Abstract:
In collective decision-making, impatient or low-stake voters are attractive allies if some group members want to stop deliberations to decide for their favored alternative. Competition for their votes can lead to hasty outcomes through strategic complementarity in the stopping decision. Majority rule is not robust in that one very impatient agent can cause the whole group to rush to a decision. This can be avoided by super-majority rule. Moreover the impacts of impatient voters and patient voters are not symmetric: one extremely patient agent will not cause the group to deliberate without end under super-majority rule unless unanimity is required.

Abstract:
We study the role rumors play in revolutions using a global game model. Agents with diverse private information rationally evaluate the informativeness of rumors about the regime strength. Without communication among agents, wild rumors are discounted and agents are generally less responsive to rumors than to trustworthy news. When agents can exchange views on the informativeness of rumors, a rumor against the regime would coordinate a larger mass of attackers than that without communication. The effect of communication can be so large that rumors can have a greater impact on mobilization than does fully trustworthy information.

Abstract:
The Hong Kong Stock Exchange briefly adopted call auctions as its closing mechanism. We find evidence of abnormally large orders and price changes during the last five seconds of the auction sessions. Such sniping attacks were associated with the expiration of derivative products, which provided an incentive for price manipulation. Prices had a tendency to revert the day following a sniping attack. Although prices were on average more informative in a closing auction procedure than in a random closing procedure, they were more prone to manipulation attempts.

Abstract:
Two organizations compete for high quality agents from a fixed population of heterogeneous qualities by designing how to distribute their resources among members according to their quality ranking. The peer effect induces both organizations to spend the bulk of their resources on higher ranks in an attempt to attract top talents that benefit the rest of their membership. Equilibrium is asymmetric, with the organization with a lower average quality offering steeper increases in resources per rank. High quality agents are present in both organizations, while low quality agents receive no resources from either organization and are segregated by quality into the two organizations. A stronger peer effect increases the competition for high quality agents, resulting in both organizations concentrating their resources on fewer ranks with steeper increases in resources per rank, and yields a greater equilibrium difference in average quality between the two organizations.

Abstract:
This paper examines the optimal design of a futures hedge program for a risk-averse multinational firm (MNF) under exchange rate uncertainty. All currency futures contracts are marked to market and require interim cash settlement of gains and losses. The MNF commits to prematurely liquidating its futures position on which the interim loss incurred exceeds a threshold level (i.e., the liquidation threshold). When the liquidation threshold is exogenously given, we show that the MNF optimally opts for an under-hedge (an over-hedge) should the futures exchange rates be not too (sufficiently) positively autocorrelated. When the liquidation threshold is endogenously determined, we show that the MNF voluntarily chooses to prematurely liquidate its futures position only if the futures exchange rates are positively autocorrelated. In the case that the futures exchange rates are uncorrelated or negatively autocorrelated, the MNF prefers not to commit to any finite liquidation thresholds.

Abstract:
This paper examines the interaction between investment and financing decisions of a firm using a real options approach. The firm is endowed with a perpetual option to invest in a project at any time by incurring an irreversible investment cost at that instant. The amount of the irreversible investment cost is directly related to the intensity of investment that is endogenously chosen by the firm. At the investment instant, the firm can finance the project by issuing debt and equity, albeit subject to an exogenously given credit constraint that prohibits the firm’s debt-to-asset ratio from exceeding a prespecified threshold. The optimal capital structure of the firm is determined by the trade-off between interest tax-shield benefits and bankruptcy costs of debt. Irrespective of whether the exogenously given credit constraint is binding or not, we show that leverage has no impact on the firm’s optimal investment intensity, thereby rendering the neutrality of debt in investment intensity. Similar to earlier work, we show that debt is not neutral to investment timing in general, and the levered firm invests earlier than the unlevered firm in particular.

Abstract:
This paper examines how changes in irreversibility of investment affect the timing and intensity of lumpy investment. We develop a continuous-time model wherein a firm is endowed with a perpetual option to invest in a project at any time by incurring a partially reversible investment cost at that instant. The amount of the investment cost is directly related to the intensity of investment that is endogenously chosen by the firm at the instant when the investment option is exercised. We show that higher irreversibility of investment induces the firm to raise its optimal investment trigger, thereby deferring the undertaking of the project. Furthermore, we show that changes in irreversibility of investment have no impact on the firm’s optimal investment intensity due to two opposing effects that exactly offset each other. Finally, we show that higher irreversibility of investment reduces the value of the investment option and, therefore, makes the firm less valuable.

Abstract:
A counterexample to the findings in the finance and development literature is that firms have achieved good performance in many developing economies where the financial sector is far from established. One widely suggested mechanism in the literature is that firms in these developing economies use a high ratio of informal financing, i.e., trade credit. This paper, by using a survey of firms in China conducted by the World Bank in early 2003, examined the impact of trade credit on firm performance. The ordinary least squares estimations showed that trade credit was significantly and positively correlated with firm performance. However, after we used the instrumental variable approach to tackle the potential endogeneity issues, trade credit no long had any impact on firm performance. The results were robust with a series of robustness checks. Our study suggested that the role of trade credit in promoting firm performance was limited.

Abstract:
This paper, by using annual surveys of manufacturing firms from 1998 to 2005 in China, first documents a positive correlation between industrial agglomeration and firm size, which is previously found in developed economies. Next, by using the system GMM and instrumental variable estimations, we identify that industrial agglomeration has a positive and statistically significant causal impact on firm size. Finally, we find that firms are more likely to benefit from locating with a number of large firms rather than with a large number of firms.

Abstract:
This paper empirically studies union effects on the performance of, and employment relations in, China’s private enterprises. The study finds a positive and statistically significant union effect on labor productivity, but not on profitability. It further finds that unions lead to better employee benefits and increased contract signing in employment. These findings suggest that, in the era of transition from a centrally planned to a market economy, unions in China’s private enterprises do promote workers’ interests as unions do in other economies. And they do that without abandoning their traditional role of harmonizing employment relations, as required by the Party.

Abstract:
It has been taken for granted in the literature on the determinants of vertical integration that the effectiveness of contract enforcement is guaranteed, which is far from true even in some developed countries. In this paper, using a World Bank data set of manufacturing firms in China, we investigate how the variations in the effectiveness of contract enforcement across China’s cities affect the degree of vertical integration. We find that weaker contract enforcement causes firms to be more vertically integrated, and that firms with greater reliance on external environment are more vertically integrated in cities with poorer contract enforcement.

Abstract:
Family control of business is prevalent in developing economies, and one of the leading theories suggests that it is a response to weak contract enforcement in such economies. In this paper, we investigate the impacts of contract enforcement on the degree of family control of business using a sample of China??s private enterprises. It is found that weaker contract enforcement is associated with the higher degree of family control of business. Our results are robust to the control for omitted variables and reserve causality issues, to the adjustment for the sample attrition bias, to the use of a sub-sample, and to the inclusion of other explanations for the family control of business.

Abstract:
This paper aims at providing an analytical examination of the criticism that the WTO is unfair and hurts the weak, developing countries. We utilize a formal model with the following features: in both the powerful and the weak economies, pressure groups lobby to influence their trade policies in their respective countries. We then allow the powerful country the exclusive ability to spend resources to facilitate the lobbying of one of the pressure groups in the weak country, thereby moving the trade policy of the developing country in favor of the powerful trading partner. Next we compare the effects of asymmetric foreign influence in a world with no WTO and no multilateral principles (most-favored-nation principle MFN and the negotiation principle of reciprocity) to a situation with WTO and its associated non-discrimination principles. We show that the weak, developing country will have less unfair concessions of market openings and in general will be better off with the WTO and with rules of nondiscrimination.

Abstract:
Using the Cultural Revolution of China as a quasi-experiment, this paper analyzes the long-term impact of interrupted education in the midst of economic transition with booming opportunities that highly reward educational qualifications. We focus on the remedial human capital investment decisions taken by individuals whose education has been interrupted by this shock. We find substantial increases in schooling levels among the adult cohorts as they invest in continuous education to make up for their interrupted schooling and take advantage of new opportunities afforded by the economic transition. Estimates of the educational loss caused by the Cultural Revolution that ignore subsequent re-investments would not accurately measure the true losses inflicted by this event.

Abstract:
This paper examines the incentive effects of the soft budget constraint on the investment behavior of firms in general and on the investment-cash flow sensitivity in particular. To this end, we develop a simple model of moral hazard that takes the soft budget constraint into account. Within this moral hazard environment, we show that investment is positively related to the amount of internal funds. We further show that the presence of the soft budget constraint deteriorates the moral hazard problem, thereby making the investment level less sensitive to the amount of internal funds. This is the case irrespective of whether the soft budget constraint renders the firm more or less liquidity constrained. To test the model’s empirical implications, we employ data of China’s listed companies for the period from 1997 to 2003. We use the share of state ownership as a proxy for the severity of the soft budget constraint. We find strong evidence that firms with larger shares of state ownership exhibit lower investment-cash flow sensitivities than firms with smaller shares of state ownership.

Abstract:
This paper develops an expected utility model of an exporting firm in a developing country where currency derivative markets do not exist. The firm faces exchange rate risk exposure to a foreign currency cash flow. To cross-hedge against this risk exposure, the firm uses currency futures and options between the foreign currency and a third currency. Since a triangular parity condition holds among the three given currencies, this available hedging opportunity, albeit incomplete, is proved to be useful in reducing the firm’s exchange rate risk exposure. We show that currency options are redundant under two rather restrictive conditions: (i) logarithmic utility functions and/or (ii) independent spot exchange rates. In a more realistic cross-hedging environment, we show that currency options are optimally used by the firm to incompletely span the missing currency futures between the domestic and foreign currencies. We also estimate the benefits of using currency options for cross-hedging purposes. The improvement in hedging effectiveness can be substantial.

Abstract:
This paper places the competitive firm under output price uncertainty in a standard efficiency wage model, wherein the work effort of labor depends on the wage rate set by the firm. Irrespective of the availability of a commodity futures market, we show that the Solow condition holds in that the equilibrium effort-wage elasticity is unity. The optimal wage rate is preference-free and independent of the underlying output price uncertainty under the efficiency wage hypothesis. Furthermore, we show that the introduction of the commodity futures market induces the firm to hire more labor and thereby produce more output if the firm is sufficiently risk averse.

Abstract:
This paper develops a real options model of a firm that operates in continuous time with an infinite horizon. The firm receives stochastic profit flows that are subject to progressive taxation. Tax progression arises from an exogenously given tax exemption threshold that makes the average tax rate increase with the tax base. The firm possesses an option to liquidate its operation, which is optimally exercised when the firm’s profit flow reaches an endogenously determined threshold level (the liquidation trigger) from above. We show that the firm’s liquidation trigger under progressive taxation increases with either a reduction in the tax exemption threshold or an increase in the corporate income tax rate. Corporate income taxes are thus not neutral when tax schedules are progressive.

Abstract:
This paper examines the optimal design of a futures hedge program by a competitive firm under output price uncertainty. Due to a capital constraint and the marking-to-market procedure of futures contracts, the firm faces endogenous liquidity risk. If the futures prices are sufficiently positively correlated, we show that the capital constraint is non-binding in that the optimal amount of capital earmarked to the futures hedge program is less than the firm’s capital endowment. Otherwise, we show that the capital constraint becomes binding in that the firm optimally puts aside all of its capital stock for the futures hedge program. In the case of non-binding capital constraint, we show that the firm’s optimal futures position is likely to be an over-hedge for reasonable preferences. In the case of binding capital constraint, the firm’s optimal futures position is an under-hedge or an over-hedge, depending on whether the autocorrelation coefficient of the futures price dynamics is below or above a critical positive value, respectively.

Abstract:
This paper examines the hedging behavior of a value-maximizing firm that lasts for two periods. The firm faces uncertain income and is subject to tax asymmetries with no loss-offset provisions. The firm has access to unbiased futures contracts in each period for hedging purposes. We impose a liquidity constraint on the firm. Specifically, whenever the net interim loss due to its first-period futures position exceeds a predetermined threshold level, the firm is forced to terminate its risk management program and thus is prohibited from trading the futures contracts in the second period. We show that the liquidity constrained firm optimally adopts a full-hedge via its second-period futures position to minimize the extent of the income risk, and an under-hedge via its first-period futures position to limit the degree of the liquidity risk.

Abstract:
This paper examines an international Cournot duopoly wherein a home firm and a foreign firm compete in the home market under exchange rate uncertainty. The foreign exporting firm, being risk averse, has incentives to hedge its exchange rate risk exposure. In a two-stage setting, we show that hedging via an unbiased currency futures market acts as a strategic device. In particular, under either constant or decreasing absolute risk aversion, an increase in the hedging volume of the foreign firm promotes its exports and deters the home firm’s output. In contrast to the well-known full-hedging result in a perfectly competitive environment, we find that the foreign firm over-hedges for strategic reasons. Furthermore, the separation result from the hedging literature under perfect competition no longer holds in our duopoly framework, i.e., equilibrium output levels depend on the risk attitude of the foreign firm as well as the probability distribution of the spot exchange rate.

Abstract:
This paper examines the investment-uncertainty relationship in a canonical real options model. We show that the critical lump-sum payoff of a project that triggers the exercise of the investment option exhibits a U-shaped pattern against the volatility of the project. This is driven by two opposing effects of an increase in the volatility of the project: (i) the usual positive effect on option value, and (ii) a negative effect on option value due to the upward adjustment in the discount rate. We further show that such a U-shaped pattern is inherited by the expected time to exercise the investment option. Thus, for relatively safe projects, greater uncertainty may in fact shorten the expected exercise time and thereby enhance investment. This is in sharp contrast to the negative investment-uncertainty relationship as commonly suggested in the extant literature.

Abstract:

This paper examines the behavior of a risk-averse multinational firm (MNF) under exchange rate uncertainty. The MNF has an investment opportunity in a foreign country. To hedge the exchange rate risk, the MNF can avail itself of customized derivative contracts that are fairly priced. Foreign direct investment (FDI) is irreversible and costly expandable in that the MNF can acquire additional capital at a higher unit price after the spot exchange rate has been publicly revealed. The MNF as such possesses a real (call) option that is rationally exercised whenever the foreign currency has been substantially appreciated relative to the domestic currency. The ex-post exercise of the real option convexifies the MNF’s ex-ante domestic currency profit with respect to the random spot exchange rate, thereby calling for the use of currency options as a hedging instrument. We show that the MNF’s optimal initial level of sequential FDI is always lower than that of lumpy FDI, while the expected optimal aggregate level of sequential FDI can be higher or lower than that of lumpy FDI. We further show that currency hedging, no matter perfect or imperfect, improves the MNF’s ex-ante and ex-post incentives to make FDI, a result consistent with the complementary nature of operational and financial hedging strategies.

Abstract:
This paper develops a real options model of a price-setting cartel under uncertainty to examine whether market demand volatility facilitates collusion or not. We show that there is a critical level of market demand (the optimal defection trigger) above which firms find it desirable to defect from the cartel. We show further that an increase in the underlying market demand uncertainty has two opposing effects on the optimal defection trigger. First, the increased market demand volatility gives rise to the usual positive effect on option value that lifts up the optimal defection trigger. Second, the increased market demand volatility calls for an upward adjustment of the discount rate and thus creates a negative effect on option value that pushes down the optimal defection trigger. We show that the negative effect dominates (is dominated by) the positive effect when the underlying market demand uncertainty is trivial (significant), thereby rendering a U-shaped pattern of the optimal defection trigger against the market demand volatility.

Abstract:
Wages, participation and unemployment are major topics for researchers of the labor market. How have these measures evolved in the economic transition of urban China? Have they evolved in accordance with those in the Statistical Yearbook and previous studies? We find that the wage level has been largely understated in the Statistical Yearbook. Our estimated participation rate is lower than that of Giles, Park, and Cai (2006) because the Urban Household Surveys (UHS) that we use include middle and small cities that are absent in their data. The unemployment rate in the published official statistics, the most frequently doubted by researchers, turns out to be significantly biased after the mid-1990s. Our analysis shows that the unemployment rate is much higher than that of the official statistics, but lower than that estimated with the China Urban Labor Survey (CULS) data in Giles, Park, and Zhang (2005). Our analysis provides the first systematic comparison of the wage level from different sources, and supplements the existing estimates on participation and unemployment using a more representative dataset for urban China.

Abstract:
Compensation policy has become one of the most important ingredients of corporate governance. In this paper we take a new look at the issue, by contrasting the use of options with that of pure stock. We do this by integrating the repricing or resetting aspect of options with that of industrial structure. We show that industry competition may play an important role in dictating which form of compensation is optimal. When aggressive competition for key professional staff is an issue, the flexibility of options may actually become a disadvantage and therefore pure stock compensation may survive as an equilibrium. Thus compensation trends can be reconciled with trends in the nature of the competitive environment.

Abstract:

This paper examines the optimal design of a futures hedge program for the competitive firm under output price uncertainty. All futures contracts are unbiased and marked to market in that they require interim cash settlement of gains and losses. The futures price dynamics follows a first-order autoregression with a random walk serving as a special case. The firm’s futures hedge program is constituted of an endogenous provision for premature termination, which depends on how the futures prices are autocorrelated. Succinctly, the firm voluntarily commits to premature liquidation of its futures position on which the interim loss incurred exceeds a predetermined threshold level if the futures prices are positively autocorrelated. In this case, the liquidity constrained firm optimally opts for an over-hedge if its preferences exhibit either constant or increasing absolute risk aversion. If the futures prices are uncorrelated or negatively autocorrelated, the firm prefers to be liquidity unconstrained and thus adopts a full-hedge to completely eliminate the output price risk.

Abstract:

This paper examines how the presence of an abandonment option affects a firm’s investment decision in general, and its operating leverage in particular. We show that the value of the abandonment option is a decreasing function of the firm’s operating leverage. Upon the introduction of the abandonment option, the firm as such optimally lowers its operating leverage. We further show that there are direct and indirect effects of the abandonment option on the firm’s optimal investment trigger, which act against each other. First, the ability to shut down production offers downside protection to the firm, thereby making the firm more eager to exercise the investment option. This is the negative direct effect that pushes down the investment trigger. Second, introducing the abandonment option to the firm induces the firm to lower its operating leverage, thereby making the firm more reluctant to exercise the investment option. This is the positive indirect effect that lifts up the investment trigger. We numerically verify that the overall effect of the abandonment option on the firm’s optimal investment trigger is negative.

Abstract:
This paper examines the impact of cross-hedging on the behavior of the risk-averse multinational firm (MNF) under multiple sources of exchange rate uncertainty. The MNF has operations domiciled in the home country and in a foreign country, each of which produces a single homogeneous good to be sold in the home and foreign markets. Since there are no currency derivative markets between the domestic and foreign currencies, the MNF has to rely on a currency futures market in a third country to cross-hedge its exchange rate risk exposure. We show that the MNF optimally opts for an under-hedge, sells less (more) and produces more (less) in the foreign (home) country. When the set of hedging instruments made available to the MNF is expanded to include currency option contracts between the domestic and third currencies, we show that the MNF optimally opts for a long option position. This paper thus offers a rationale for the cross-hedging role of currency options for MNFs under multiple sources of exchange rate uncertainty.

Abstract:

Using data from China’s Annual Survey of Industrial firms from 1998 to 2005, we find strikingly different patterns of firm productivity and exporting behavior between China’s indigenous firms and foreign multinationals operating in China. Among indigenous firms, exporters are more productive than non-exporters, and the more productive firms self-select to become exporters. But the results for foreign multinationals are just the opposite. We then propose an explanation to our findings by expanding the scope of firm heterogeneity from mere productivity differences to include differences in the fixed costs of exporting relative to local sales across firms of different national origins.

Abstract:

The rise and decline of China’s collectively-owned enterprises, a hybrid of public and private ownership, has led to intensive debates about the costs and benefits of government ownership. It has been argued that government ownership may help firms gain access to production inputs and infrastructural services, but government officials may use public enterprises to pursue private benefits. From a panel dataset of 13,733 China’s collectively-owned enterprises for the period of 1998-2003, it is found that collectively-owned enterprises, once privatized, encountered an increase in the cost of goods sold to sales ratio but had a decrease in the managerial expenses to sales ratio. These changes in the costs and benefits of government ownership are found to be most significant in the first privatization and take place immediately after the privatization.

Abstract:

This paper examines the impacts of economic institutions, including property rights protection and contract enforcement, on the location choice of foreign direct investment. From a data set of 6,288 U.S. multinationals investing in various China’s regions for the period of 1993-2001, it is found that U.S. multinationals prefer to invest in those regions that have better protection of intellectual property rights, lower degree of government intervention in business operations, lower level of government corruption, and better contract enforcement. Our results are robust to alternative measures of economic institutions, and to the inclusion of control variables such as those for agglomeration economies, and other traditional factors of FDI location choice.

Abstract:
The 6th Plenum of the 16th Central Committee of the Communist Party of China (CPC) concluded on October 11, 2006, with the commitment to establish a harmonious society by 2020. The obvious implication from this commitment is that the present major social, economic and political trends are not leading to a harmonious society or, at least, not leading to a harmonious society fast enough. Analytically, if the Chinese economy is depicted as a speeding car, then are three classes of failures that could result in a car crash: (1) hardware failure, (2) software failure, and (3) power supply failure.

A hardware failure refers to the breakdown of an economic mechanism, a development that is analogous to the collapse of the chassis of the car. Probable hardware failures are (1) a banking crisis that dislocates production economy-wide, and (2) a budget crisis that necessitates reductions in important infrastructure and social expenditure.

A software failure refers to a flaw in governance that creates frequent widespread social disorders that disrupt production economy-wide and discourage private investment. This situation is similar to a car crash that resulted from a fight among the people inside the speeding car. Probable software failures could come from (1) the present high-growth strategy creating so much inequality, and corruption that severe social unrest results; and (2) the state not being able to meet the rising social expectations about governance issues.

A power supply failure refers to the economy being unable to move forward because it hits either a natural limit or an externally-imposed limit, a situation that is akin to the car running out of gas or having its engine switched off because an outsider reached in and pulled out the ignition key. Examples of power supply failures are (1) an environmental collapse; and (2) a collapse in China’s exports because of a trade war.

My assessment is that the highest probability event in hardware failure is the weakening of China’s fiscal position; the highest probability event in software failure is social disorder, and the highest probability event in power supply failure is water shortage. And my ranking of the probability of these three specific negative events in descending order is social disorder caused by outmoded governance, water shortage as a result of inept environmental management, and fiscal crisis generated by the repeated recapitalization of the state banks and the rapid aging of the population (cont…).

Abstract:
This paper examines the impact of liquidity risk on the behavior of the risk-averse multinational firm (MNF) under exchange rate uncertainty in a two-period dynamic setting. The MNF has operations domiciled in the home country and in a foreign country, each of which produces a single homogeneous good to be sold in the home and foreign markets. To hedge the exchange rate risk, the MNF trades currency futures contracts that are marked to market at the end of the first period. Liquidity risk is introduced to the MNF by a liquidity constraint that obliges the MNF to prematurely liquidate its futures position whenever the interim loss incurred from this position exceeds a prespecified threshold level. We show that the liquidity constrained MNF optimally opts for an under-hedge, sells less (more) and produces more (less) in the foreign (home) country. When the set of hedging instruments made available to the liquidity constrained MNF is expanded to include nearby currency futures and option contracts, both of which mature at the end of the first period, we show that the MNF optimally opts for a long nearby futures position, a short distant futures position, and a long option position. This paper thus offers a rationale for the hedging role of futures spreads and currency options for liquidity constrained MNFs.

Abstract:

In this paper we infer the return on capital from firms’ actual capital expenditures and study how institutions affect corporate investment efficiency through an examination of various crosssections of the inferred return on capital. We apply the Generalized Method of Moments (GMM) estimator derived from a structural investment model to a large sample of Chinese industrial firms. Based on the estimated structural parameters, we compute the stochastic discount rate perceived by managers to decide investment spending. We document robust evidence that ownership is the primary institutional factor affecting the firm-level return on capital in China. The results from our benchmark estimation show that return on capital for a non-state firm is approximately 10 percentage points higher than that of an otherwise similar state firm. We also find that privatization leads to improvement in corporate investment efficiency. Applying the same estimation to the universe of China’s listed firms, we further identify that firms with better corporate governance have higher returns on capital. Our estimates show that redirecting the capital from less efficient state sector to more efficient private sector can unleash a 4.4% GDP growth in China every year, and that the deadweight loss due to capital mis-allocation is about 4% of China’s GDP.

Abstract:
Industry-specifc human capital reduces the incentive for older workers to leave declining industries and raises the incentive for younger workers to join growing industries. Using the industry restructuring experience of Hong Kong, we find that a one percent increase in employment share of an industry is associated with a 0.60 year decrease in the average age of its workforce. The relationship is more pronounced among less educated workers, who have less general human capital, and male workers, who are more committed to the labor force, than among well educated workers and female workers.

Abstract:
This paper analyzes changes in the gender earnings gap in urban China during 1988-2004 using urban household survey data. The mean female/male earnings ratio declined by about 10.1 percentage points from 86.3% in 1988 to 76.2% in 2004. The main contributors to this diverging trend are the rapid increases in returns to both observed and unobserved skills that weigh the skill deficit of women more heavily. Women on the average also lose due to an enlarged gap in unobserved skills or increased discrimination. Although the gender gap in observed skills such as education narrows over the years, which works to reduce gender gap, the effect is not strong enough to offset the negative forces. We also examine changes in gender earnings gap in the bottom and top percentiles of the earnings distribution and changes in gender earnings inequality in four sub-periods, namely, 1988-1994, 1994-1998, 1998-2001, and 2001-2004.

Abstract:
In this paper, we study how short-sale constraints affect asset price and market efficiency. We consider a fully rational expectations equilibrium model, in which investors trade to share risk and to speculate on private information in the presence of short-sale constraints. Short-sale constraints limit both types of trades, and thus reduce the allocational and informational efficiency of the market. Limiting short sales driven by risk-sharing simply shifts the demand for the asset upwards and consequently its price. However, limiting short sales driven by private information increases the uncertainty about the asset as perceived by less informed investors, which reduces their demand for the asset. When this information effect dominates, short-sale constraints actually cause asset prices to decrease and price volatility to increase. Moreover, we show that short-sale constraints can give rise to discrete price drops accompanied by a sharp rise in volatility when prices fail to be informative and the uncertainty perceived by uninformed investors surges.

Abstract:

This paper presents a new approach to infer return on capital from firms’ capital expenditures, and then examines how institutions and financial development affect this implied return on capital. We apply the Generalized Method of Moments (GMM) estimator derived from a structural investment model to a large sample of Chinese industrial firms in China. Based on the estimated structural parameters, we compute the stochastic discount rate perceived by the managers to decide investment spending. We identify robust evidence that this return on capital measure is a function of variables capturing institutions and financial development. The results from our benchmark estimation show that return on capital for a non-state firm is more than 10 percentage points higher than that of an otherwise similar state firm. We document evidence that regions with better institutions and a market-prone financial system have more efficient non-state sectors. Our estimates show that redirecting the capital from less efficient state sector to more efficient private sectors can unleash a 4.5% GDP growth in China every year, and the deadweight loss due to capital mis-allocation is about 8% of China’s GDP.

Abstract:

Fiscal decentralization introduced as part of China’s economic reform since 1979 has unleashed strong incentives for China’s local governments to pursue economic development, but the same incentives have also led to local protectionist policies inhibiting the process of regional specialization. This paper focuses on the constraints or freedom with which local governments can implement their protectionist policies. Using a panel data of 29 China’s regions over the time period of 1985-1997, we find that China’s political system of bureaucratic integration (specifically, concurrent appointment of local government officials in the central government) imposes constraints on the local governments from practicing protectionism. We also find that the effectiveness of local protectionist policies is limited by market competition, specifically, competition from foreign-invested firms operating in China and foreign imports. Our results on the role of local protectionism remain robust to controls for the regional variations in the size of the economy and the stage of economic development.

Abstract:

Public housing represents a sizable subsidy to housing cost and it has to be strictly rationed among competing users. When rationing occurs, resources may not be allocated to their most valuable uses because people cannot effectively convey the intensity of their preferences. This study investigates the hidden costs of public housing from the perspective of the misallocation of housing units to tenants and examines how this misallocation affects these tenants’ lives. This paper shows that public housing occupants are more immobile than private housing occupants. Conditional on moving, however, public housing occupants are more likely than their private housing counterparts to have to move farther away from their original district or region of residence. Due to the lack of choice and mobility, public housing occupants are also less likely to work in the same district or region as their place of residence.

Abstract:
This paper examines the effect of uncertainty on investment timing in a canonical real options model. We show that the critical value of a project that triggers the exercise of the investment option exhibits a U-shaped pattern against the volatility of the project. This is due to the two countervailing risk and return factors in effect. We further show that such a U-shaped pattern is inherited by the expected time to exercise the investment option. Thus, for relatively safe projects, greater uncertainty shortens the expected exercise time and thus enhances investment. This is in sharp contrast to the negative investment-uncertainty relationship commonly found in the extant literature. Finally, we show that the positive investment-uncertainty relationship is more likely for high growth projects than for low growth projects.

Abstract: This paper examines the hedging decision of an international firm facing exchange rate risk exposure to a foreign currency cash flow. Financial markets are incomplete in that there are no hedging instruments directly related to the home currency. There is, however, an unbiased currency forward market between the foreign currency and a third currency accessible to the firm. A triangular parity condition holds among the home, foreign, and third currencies, thereby making cross-hedging opportunities available. If the spot exchange rate of the home currency against the third currency and that of the third currency against the foreign currency are positively (negatively) correlated in the sense of regression dependence, we show that the firm’s optimal forward position is an under-hedge or an over-hedge, depending on whether the firm’s Arrow-Pratt measure of relative risk aversion is everywhere less (greater) or greater (less) than unity, respectively.

Abstract:
We document that the value-weighted aggregate discretionary accruals have significant power in predicting the one-year-ahead stock market returns between 1965 and 2004. The predictive relation is stable and robust to different ways to measure market returns and discretionary accruals as well as to the inclusion of other known return predictors. The value-weighted aggregate discretionary accruals are positively related to future stock market returns and negatively correlated with contemporaneous market returns. Our extensive analysis favors the managerial equity market timing story and suggests that managers of large firms have stronger market timing ability than managers of small firms.

Abstract:

This study documents that changes in credit ratings significantly affect chief executive officer’s (CEO’s) pay-performance sensitivity. Modeling credit ratings changes and changes in CEO incentive levels as jointly endogenous, we identify significant and robust evidence that CEO incentives tend to increase subsequent to the downgrades of credit ratings, and decrease after the upgrades. We also find that the effect of credit ratings changes on CEO incentives is stronger for larger firms, for firms with investment grade debts and larger presence of institutional investors, and for firms whose investors have less access to public information. More importantly, we find the credit ratings changes have larger impact on CEO incentives for firms whose CEOs have been either over- or under-compensated previously. Our empirical findings suggest that rating agencies’, or more generally, debt-holders’, disciplines complement equity-based incentive pay to resolve agency conflicts between managers and stakeholders.

Abstract:

The massive downsizing of the state-owned sector and the concomitant impressive growth of the private sector at the end of the 1990s have altered the nature of the Chinese labor market. By bringing in more competition and market mechanisms, they have contributed to increasing labor turnover and competitiveness in market wages. Using two urban household surveys for 1995 and 2002, this paper analyzes the evolution of labor market segmentation in urban China, by applying an extended version of Oaxaca-Blinder decomposition methods. During the 7-year period, the sharp increase in earnings for all workers however shows substantial differences across ownership, economic sectors, and regions. We find strong evidence of a multi-tiered labor market along these three major lines and highlight increasing segmentation within each of the three dimensions, the gap between the privileged segments of the labor market and the most competitive segments widening over time.

Abstract:

In the Stackelberg duopoly experiments in Huck et al. (2001), the followers behave less timidly than predicted by conventional theory and the leaders act less aggressively than predicted. We provide a parsimonious explanation to these anomalies by simplifying the model of Fehr and Schmidt (1999) in two directions — there is no advantageous inequality aversion and all players with non-standard preferences have the same degree of disadvantageous inequality aversion. Maximum likelihood procedures show that the predictions of this model are consistent with the data in Huck et al. (2001), and that more than a third of the players have high degree of disadvantageous inequality aversion which is statistically different from zero.

Abstract:

The reform of China’s state-owned enterprises (SOEs) has been characterized by a gradual and selective approach. In fact there was no privatization at all until mid 1990s, some fifteen years after China started its economic reform. Despite of years of economic reform, state ownership remains significant in the economy. Most of the SOEs are money losing, and the few exceptional ones tend to be sheltered by government protection in selected industries. Yet China has been enjoying one of the most spectacular growth experiences in the world history, and much of the growth is driven by non-state-owned enterprises (non-SOEs), including foreign invested enterprises operating in China and China’s own private enterprises. Given the poor financial performance of SOEs, the co-existence of state ownership and private ownership in China is a puzzling phenomenon. Does state ownership exist solely for the benefit of politicians, as is modeled by Andrei Shleifer and Robert W. Vishny (1994), or has state ownership played any role in China’s spectacular growth? Is there any rationale behind China’s gradual and selective approach towards privatizing its SOEs? What types of SOEs does the Chinese government choose to privatize? What are the consequences of privatization? In this paper, we offer a theory of SOE reform in the context of China, which has predictions on the types of SOEs to be chosen for privatization and the results of privatization. We then present empirical evidence supporting the basic premise of the theory and its theoretical predictions.

Abstract:

This paper examines the behavior of the competitive firm that exports to two foreign countries under multiple sources of exchange rate uncertainty. There is a forward market between the home currency and one foreign country’s currency, but there are no hedging instruments directly related to the other foreign country’s currency. We show that the separation theorem holds when the firm optimally exports to the foreign country with the currency forward market. The full-hedging theorem holds when the firm either exports exclusively to the foreign country with the currency forward market or when the relevant spot exchange rates are independent. In the case that the relevant spot exchange rates are positively (negatively) correlated in the sense of regression dependence, the firm optimally opts for a short (long) forward position for cross-hedging purposes.

Abstract:
In organizing production, many firms conduct bi-sourcing, i.e., acquiring the same set of inputs by both buying from external suppliers (outsourcing) and producing in componentmanufacturing subsidiries (insourcing). We show that, by adopting the bi-sourcing strategy, firms can use the in-house production to mitigate the holdup problem in outsourcing and introduce elements of competition from outsourcing in dealing with the incentive problem in insourcing (the cross-threat effect). When firms conduct bi-sourcing in the global economy consisting of high-waged North and low-waged South, they need to make the location choice for both insourcing and outsourcing. We find that the low wage in the South can stimulate investment incentive by component suppliers no matter whether they are internal or external suppliers (the cost difference effect). Furthermore, firms may achieve better cross-threat effect by locating overly strong (or weak) supplier in the disadvantageous North (or advantageous South) (the balancing effect). We demonstrate that locating both internal and external suppliers in the South often yields the highest production efficiency among all possible patterns of bi-sourcing. Our results on bi-sourcing patterns are consistent with some recent trends in world trade such as the growing vertical specialization, intrafirm trade and complementarity between foreign direct investments and trade.

Abstract:

This paper examines the behavior of a risk-averse multinational firm (MNF) making investment in a foreign country under exchange rate uncertainty. To hedge the exchange rate risk, the MNF has access to an unbiased currency forward market. Foreign direct investment (FDI) is irreversible and sequential in that the MNF can acquire additional capital after the exchange rate uncertainty is completely resolved. The MNF as such possesses a real (call) option that is rationally exercised whenever the foreign currency has been substantially appreciated relative to the domestic currency. We show that the MNF’s optimal initial level of sequential FDI is always lower than that of lumpy FDI, while the expected optimal aggregate level of sequential FDI can be higher or lower than that of lumpy FDI. We further show that the presence of the currency forward market improves the MNF’s incentives to make FDI, both ex ante and ex post.

Abstract:
This paper examines the impact of liquidity risk on the behavior of the competitive firm under price uncertainty in a dynamic two-period setting. The firm has access to unbiased one-period futures and option contracts in each period for hedging purposes. A liquidity constraint is imposed on the firm such that the firm is forced to terminate its risk management program in the second period whenever the net loss due to its first-period hedge position exceeds a predetermined threshold level. The imposition of the liquidity constraint on the firm is shown to create perverse incentives to output. Furthermore, the liquidity constrained firm is shown to optimally purchase the unbiased option contracts in the first period if its utility function is quadratic or prudent. This paper thus offers a rationale for the hedging role of options when liquidity risk prevails.

Abstract:
This paper examines the interaction between operational and financial hedging in the context of a risk averse competitive exporting firm under exchange rate uncertainty. The firm is export-flexible in that it makes its export decision after observing the realized spot exchange rate. However, export-flexibility is limited by certain minimum sales requirements due to long-term considerations. This creates a piecewise linear exchange rate exposure. If the firm is allowed to use customized derivatives contracts, its optimal hedge position can be replicated by selling currency forward contracts and call options. If the firm is restricted to use forward contracts as the sole hedging instrument, optimal output is unambiguously smaller. Introducing currency call options thus stimulates production. An extension analyzes more general types of exchange rate exposure.

Abstract:
This paper studies how shifts in the distribution of quality on one side of the market affects earnings on the other side in a model of one-to-one matching. A more dispersed distribution of quality hurts the low ability agents on the other side because they are matched to inferior partners. Earnings being a differential rent in these markets, this pulls down the earnings of high quality agents as well. It is shown that a more dispersed ability distribution reduces total earnings on the opposite side of the market. Under some conditions, all agents on that side are hurt.

Abstract:

This paper examines the optimal bidding and hedging decisions of a risk-averse firm that takes part in an international tender. The firm faces multiple sources of uncertainty: exchange rate risk, risk of an unsuccessful tender, and business risk. The firm is allowed to trade unbiased currency futures contracts to imperfectly hedge its contingent foreign exchange risk exposure. We show that the firm shorts less (more) of the unbiased futures contracts when its marginal utility function is convex (concave) as compared with the case that the marginal utility function is linear. We further show that the curvature of the marginal utility function plays a decisive role in determining the impact of currency futures hedging on the firm’s bidding behavior. Sufficient conditions that ensure the firm bids more or less aggressively than in the case without hedging opportunities are derived.

Abstract:

This paper examines the interaction between operational and financial hedging in the context of an internationally competitive but domestically monopolistic firm under exchange rate uncertainty. Operational hedging is modeled by letting the firm make its export decision after it has observed the true realization of the then prevailing spot exchange rate. Financial hedging, on the other hand, is modeled by allowing the firm to trade fairly priced exotic derivatives that are tailor-made for the firm’s hedging need. We show that both operational and financial hedging unambiguously entice the firm into producing more. We further derive sufficient conditions under which operational hedging dominates (is dominated by) financial hedging in terms of promoting the firm’s optimal output.

Abstract:
The objective of this study is to measure the economic benefits of infrastructure investments. Specifically, I consider an investment in China that doubled the tracks of a one-thousand-mile-long railroad in 1994. This capacity expansion, intuitively, may gain welfare by increasing interregional trade and decreasing prices of traded goods. I first estimate the impact of this investment on price differences across regions. The identification relies on a key feature of my setting that the expansion in rail capacity only affects the trade of goods in one direction. I find that the investment significantly reduces interregional price gaps, and this effect is robust to both reduced-form and structural estimation techniques. In the second stage of analysis, using a partial equilibrium framework, I derive a welfare measure that transforms the estimated price-gap effect into welfare estimates. I find that the internal rate of return of the investment may significantly exceed the costs of capital in China.

Abstract:
There are two main theories about the costs and benefits of public ownership: the efficiency theory that public ownership is a means for government to achieve its social objectives and the political patronage theory that public ownership is used by government officials to pursue their personal gains. The latest development of the efficiency theory emphasizes that state-owned enterprises engage in multiple tasks and one of the tasks has externalities. This theory implies that the incentives for privatization depend on the level of the government. Using a panel data set of 26,153 state-owned enterprises in China from 1995 to 1997, this paper tests this as well as other implications of the two main theories of public ownership and finds strong support for the efficiency theory, especially the multi-task efficiency theory, but mixed support for the political patronage theory.

Key words: multi-task efficiency theory of public ownership, political patronage theory of public ownership, divergent interests of local and central governments, privatization

Abstract:

Poor protection of private properties – manifested in the risks of expropriation and discrimination – has limited the access to bank loans by private enterprises in developing and transition economies. Under those circumstances, private entrepreneurs have resorted to ingenious ways of enhancing the de facto protection of private properties through political participation and philanthropic activities. Using a data set of 3,073 private enterprises in China, this paper empirically investigates the effects of formal and de facto property rights protection on the access to bank loans.

Abstract:

This paper examines the stock market reactions to the US biotech firms’ innovation news announcements during 1983-1993. Besides the positive abnormal returns observed during the announcement period, the paper identifies a medium-horizon negative drift in the stock price subsequent to firms’ innovative events. The observed negative drift is robust to the benchmarks and procedures used in calculating the abnormal returns. Cross-sectional analysis demonstrates that the post-announcement abnormal returns are positively related to a firm’s technology depth (measured by R&D intensity) and book-to-market ratio, negatively related to the size. The evidence favors the investor expectational errors hypothesis, and suggests that R&D or other intangibles are market value relevant in the high-tech firms.

Abstract:
We investigate the role of information-based trading in affecting the risk-incentive relation. We analytically decompose the risk-incentive relation into two o setting components. Directly reducing incentive aside, a greater uncertainty increases the level of information-based trading which enhances incentives indirectly. Numerical analysis shows that the indirect effect is about 40-50% of the direct effect in size and contributes significantly to social welfare improvement. Empirical tests using probability of informed trading (PIN) and CEO compensation data show that a median level of information-based trading on average causes a 20% offset of the risk-incentive tradeoff and improves CEO incentives by 15-96%.

Abstract:

We find that an informationally efficient stock market induces firms to rely more heavily on pay-for-performance schemes. We construct five stock market informativeness measures using stock trading data and analysts’ earnings forecast data. These variables, individually and collectively, account for the cross-sectional variation in chief executive officer (CEO) payperformance sensitivity well. Our results are robust to the choice of estimators, samples, time periods, incentive measures, model specifications, and estimation methods. We also analyze the properties of the pay-performance sensitivities of nonCEO executives and executive teams; These have similar properties as CEO pay-performance sensitivity.

Abstract:

In this paper, we explore the possibility of developing “vulnerability” indicator for gauging the health of the economy of Hong Kong. An important measure of “health” to be considered is the popular maximum Lyapunov exponent in the dynamical system literature which measures the sensitivity to initial conditions of a deterministic function. Other key economic and financial indicators that have impact on the Hong Kong financial market such as yield spreads & forward rates are also considered. Lyapunov exponent is often used to indicate the presence of nonlinearity and has not been used as an explanatory variable in the literature, when in fact the Lyapunov exponent also contains useful information about a dynamical system and such information can be usefully exploited. Using stepwise probit regression an indicator of the vulnerability of the financial sector is obtained which is able to indicate empirically observed crisis. An interesting feature of this indicator function is that the local maximum Lyapunov exponent plays a non-negligible role in predicting the status of the economy.

Abstract:
Using the annual survey on large and medium-sized industrial enterprises in China by the National Bureau of Statistics, this paper examines enterprise performance in north-east China. It shows clearly that the privatization of SOEs in the north-east region during 1995-2002 is rapid and often more aggressive than in the rest of China. The improvement in profitability and productivity of enterprises in the north-east China is also as significant as in the rest of China. Reforms in the north-east region have led to dramatic changes in the allocation of capital and labor, largely consistent with the national trend. Using regression analysis on the firm-level panel data, the study is able to measure and explain the differences in firm productivity and profitability across time, region, ownership, and market conditions, and to identify the remaining performance gaps that are specific only to the north-east region. The results of this study indicate that while the north-east region should continue the standard market-oriented reforms, such as privatization, encouraging market competition, and attracting FDI, it should also work hard to catch up in institutional reforms that could improve its local business environment since the performance gaps that are due to specific to its location are still quite large.

Abstract:

This paper uses provincial macro-data from the mid-1980s onwards to investigate the determinants of land-use choice in rural China, by paying a particular attention to the decision to plant trees as competing with agriculture. The evidence supports the importance of economic motivations in the afforestation decision. A profit-seeking behavior is found to be at stake in the decision to plant trees, which is made according to both the relative profitability of forestry against agriculture, and their relative risks. Afforestation is also found to strongly depend on the pressure upon land as well as on household wealth.

Abstract:
The Battle of the Sexes game, which captures both conflict and coordination problems, has been applied to a wide range of situations. We show that, by reducing conflict of interest and enhancing coordination, (eventual) turn taking supported by a ‘turn taking with independent randomizations’ strategy allows players to engage in intertemporal sharing of the gain from cooperation. Using this insight, we decompose the benefit from turn taking into conflict-mitigating and coordination-enhancing components. Our analysis suggests that an equilibrium measure of the ‘degree of intertemporal conflict’ provides an intuitive way to understand the sources of welfare gain from turn taking in the repeated Battle of the Sexes game. We find that when this equilibrium measure is higher, players behave more aggressively and the welfare gain from turn taking is smaller.

This paper uses U.S. Census data from 1980, 1990 and 2000 to estimate synthetic-cohort life cycle effects of fertility on women’s and couples’ labor supply. Multiple births are used as an instrument to control for unobserved heterogeneity. For single women, the causal effect of fertility has declined significantly over time. Couples, however, have become more specialized along traditional lines, with married men tending to increase labor earnings rather than reduce hours worked.

Abstract:

This paper investigates whether market competition enhances firms’ incentives to hide profits. We develop a theoretical model of firms’ profit hiding behavior in competitive environments and derive several testable hypotheses. We then test the model using a database that covers more than 20,000 large-and-medium-sized industrial firms in China during the period 1995-2002. Our findings show that firms in more competitive market environments — as well as firms in relatively disadvantageous positions — hide a larger share of their profits. This suggests that policies intended to promote competition should be accompanied by policies aiming at strengthening institutional infrastructure and at leveling playing fields.

Abstract:

In this paper, we provide a preliminary survey of the burgeoning literature on corporate governance in China. We structure the existing research around three themes: (1) What are the current corporate governance practices in China? (2) How do these corporate governance practices affect Chinese firms’ valuation and various corporate policies? (3) How does China’s unique institutional setting pre-determine the governance model adopted in China? The evidence indicates that the current governance practices adopted in China can be best described as a control-based model, which contrasts strikingly with the market-oriented model commonly used in the US and UK, and championed by most corporate governance advocates. The evidence also shows that Chinese firms, whose corporate governance practices deviate from the control based model, demonstrate stronger performance, and tend to make decisions in line with the shareholders’ interest. The evidence from the literature also suggests that the control-based model root in the “administrative governance” approach adopted by the Chinese regulatory authorities, and is tailed to China’s specific institutional setting.

Abstract:

We find that accruals mispricing is more pronounced for stocks with higher level of probability of informed trading (PIN). We interpret it as the evidence of informed traders using their proprietary information on accruals quality to trade against average investors. The informed traders’ arbitrage generates an annualized size and book-to-market adjusted abnormal return of 19.81% over the 1993-2002 period. Using three different methods to estimate the transaction costs and the impact of various market frictions on the accruals strategy, we find that informed traders make an abnormal return of 6.5%–17.53% after trading costs. Our findings are robust to testing methods, asset pricing models used, and various ways of controlling for trading costs. They suggest that the persistence of accruals anomaly might be driven by the non-diversifiable information risk rather than higher trading costs of extreme accruals stocks. We also design a strategy for uninformed traders to mimick informed traders’ behavior, and find that it generates profits equivalent to those obtained by the informed traders.

Abstract:

This paper explains how China was able to develop a large, active, and technologically advanced stock market in the 1990s while still maintaining its salient socialistic institutions of state ownership and monopolistic control over financial intermediation and offering shareholders only weak legal protection. We argue that the marriage of socialism and capitalism that took place during the establishment of China’s poorly regulated stock market has produced an arena for rent-seeking local governments and state-owned enterprises and a casino for speculators. We show how China’s stock market development in the 1990s was driven primarily by rent-seeking and speculative activities rather than by value-driven transactions between investors and fund seekers.

Abstract:
This paper examines the behavior of a multinational firm (MNF) under exchange rate uncertainty. The MNF has operations domiciled in the home country and in a foreign country. Each of these two operations produces a single homogeneous good to be sold in the home and foreign markets. To hedge the exchange rate risk, the MNF has access to an intertemporally unbiased currency futures market. All currency futures contracts are marked-to-market and thus require interim cash settlement of gains and losses. We impose a liquidity constraint on the MNF in that the MNF is forced to prematurely liquidate its futures position from which the interim loss exceeds a predetermined threshold level. If the MNF’s utility function satisfies decreasing absolute risk aversion, we show that the MNF optimally opts for a short under-hedge. Furthermore, the MNF sells less (more) and produces more (less) in the foreign (home) country in response to the imposition of the liquidity constraint.

Abstract:
This paper examines the interplay of the financing and hedging decisions of a risk-averse multinational firm having a wholly-owned foreign subsidiary. Exchange rate risk management of the multinational firm is shown to have direct impacts on its international capital structure decision and on its currency of denomination decision. If a currency forward market exists, the multinational firm will devise its international capital structure so as to minimize the global weighted average cost of capital. Or else the multinational firm has to rely on a money market hedge through issuing more foreign currency denominated debt and less domestic currency denominated debt, thereby resulting in a higher global weighted average cost of capital.

Abstract:

Most companies do not compare acquisition and alliance before picking one, and often end up with the “wrong” thing (Dyer, Kale, and Singh, 2004). Even though academic literature does compare acquisitions and alliances, there exist inconsistent explanations and findings. In this study, we reexamine the choice of multinational firms in partial-ownership acquisitions and start-ups (joint ventures) when they expand into an emerging economy, China. Drawing upon the existing literature, we examine the influence of product relatedness, competitive rivalry, task-specific knowledge, and location-specific knowledge. Our sample consists of 2,152 partial acquisitions and start-ups in China in 257 product sectors from 23 countries between 1985 and 2001. Our findings offer new insights on partial ownership international expansion strategies.

Abstract:
This paper introduces a model in which rational voters select news sources with ideological positions similar to their own. We find that extreme media outlets do not influence political outcomes, and that new entry always makes party policies more centrist. In an optimal media, diversity of viewpoints is more important than unbiased reporting. A slightly partisan media outlet, which is trusted by the supporters of a party, is more effective than a completely centrist one in inducing the party to adopt less partisan policies. In a commercial media market, voter welfare is typically higher under duopoly than under monopoly.

This paper uses annual data spanning 1962 to 2003 to examine whether business and inflation cycles have become more similar across Chinese provinces as the economy has been liberalised and modernised. We find evidence of synchronisation, although business cycles in a group of mainly north-western provinces appear to have diverged from those in the rest of China. Both the business and inflation cycles in Hong Kong seem to have become increasingly synchronised with those in the Mainland over recent years.

Abstract:

There is no doubt that part of People’s Republic of China (PRC)’s FDI inflows belongs to the return of the Chinese capital that has gone aboard escaping the foreign exchange control. This paper shows a large part of the capital originally created in PRC has managed to go abroad and has stayed aboard waiting for opportunities to return back to PRC. On average the round tripping FDI, e.g. the returning Chinese capital, is about 20% to 30% of the capital flight of various estimations. The pattern of capital creation and movement uncovered here suggests that competition for FDI flows are not a zero-sum game. The FDI inflows are not simply a fix sum to be competed away among different countries. Instead, PRC’s experiences have shown that FDI inflows are probably endogenously determined by the capacity of the hosting countries to create new capital. When a developing economy like PRC is creating new capital, a significant part of the new capital is likely to find its way abroad through mis-invoicing in international trade, smuggling, and other channels of capital flight since the people who are creating the new capital have strong incentives to diversity domestic risks and to seek better protection of property rights. The accumulated capital flight then forms the base for sustained round tripping FDI back home when the opportunities to make profits and create new capital at home continue to exist.

Abstract:

People’s Republic of China (PRC) in recent years has emerged as the largest recipient of foreign direct investment (FDI) in the world. Many analysts and government officials in the developing world have increasingly expressed concerns that they are losing competitiveness to PRC. Is PRC diverting FDI from other developing countries? Theoretically, a growing PRC can add to other countries’ direct investment by creating more opportunities for production networking and raising the need for raw materials and resources. At the same time, the extremely low Chinese labor costs may lure multinationals away from sites in other developing countries when the foreign corporations consider alternative locations for low-cost export platforms.

 

In this paper, we explore this important research and policy issue empirically. We focus our studies on East and Southeast Asia as well as Latin America. For Asia, we use data for eight Asian economies (Hong Kong, China, Taipei,China, Republic of Korea, Singapore, Malaysia, Philippines, Indonesia and Thailand) for 1985-2002 while for Latin America, we use data for sixteen Latin American economies (Argentina, Bolivia, Brazil, Chile, Columbia, Costa Rica, Ecuador, El Salvador, Guatemala, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay and Venezuela) for 1990-2002. We control for the standard determinants of their inward direct investment. We then add PRC’s inward foreign direct investment as an indicator of the “PRC Effect”. Estimation of the coefficient associated with the PRC Effect proxy gives us indications about the existence of the PRC Effect.

 

We have three results: (1) The level of PRC’s foreign direct investment is positively related to the levels of inward direct investments of economies in East and Southeast Asia, while the PRC Effect is mostly insignificant for Latin American nations; (2) the level of PRC’s foreign direct investment is negatively related to the direct investment of these economies as shares of total foreign direct investments in the developing countries; (3) The PRC Effect is generally not the most important determinant of the inward direct investments of these economies. Market sizes and policy variables such as openness and corporate tax rates tend to be more important.

Abstract:

By any measure, China’s policy to attract foreign direct investment (FDI) as a pillar of its development strategy has been a huge success. This FDI policy is promoting growth in China. But is this development strategy beggar-thy-neighbor? In other words, is China taking direct investment away from other Asian developing economies? Theoretically, a growing China can add to other countries’ direct investment by creating more opportunities for production-networking and raising the need for raw materials and resources. At the same time, the extremely low Chinese labor costs may lure multinationals away from other Asian sites when the foreign corporations consider alternative locations for low-cost export platforms.

 

In this paper, we explore this developmental issue empirically. We use data for eight Asian economies (Hong Kong, Taiwan, Republic of Korea, Singapore, Malaysia, Philippines, Indonesia and Thailand) from 1985 to 2001 and control for the determinants of their inward direct investment. We then add China’s inward foreign direct investment as an indicator of the “China Effect”. Due to issues of simultaneity, we use a random effects simultaneous equation model to estimate our coefficients.

 

We have three results: (1) The level of China’s foreign direct investment is positively related to the levels of these economies’ inward direct investments; (2) the level of China’s foreign direct investment is negatively related to the direct investment of these economies as shares of total Asian foreign direct investments; (3) The China Effect is generally not the most important determinant of the inward direct investments of these economies. Policy and institutional factors such as openness, corporate tax rates and the level of corruption tend to be more important.

Abstract:

We examine forward sale (pre-sale) activities on the volatility of spot prices in the real estate market. The abundance of pre-sales data and major changes in regulatory control on the pre-sale market during the 90’s in Hong Kong allow us to undertake empirical tests using Hong Kong’s real estate data. Our results show that the volatility of spot prices increased significantly after forward sales were severely dampened by regulatory control measures introduced in 1994, but decreased again when the measures were partly relaxed in 1998. The results contribute to the long lasting debate on whether the introduction of a futures market reduces the volatility of spot prices. Previous studies were mainly conducted in markets with low transaction costs, notably financial markets. By utilizing the unique regulatory changes in the pre-sale market of Hong Kong, we are able to conduct an experiment on the conditional volatility of spot prices in a high information-cost environment. This sheds light on the mixed evidence found in the finance literature.

Abstract:

A major empirical interest in growth studies is whether permanent changes in economic fundamentals affect the long-run growth rate or not. However, a direct time series analysis of this hypothesis may not always be feasible because the permanence of many such changes is rather questionable. This paper explains why examining the long-run effects of temporary changes in investment share on per capita output provides indirectly the answer regarding the effects of (possibly hypothetical) permanent changes in investment share, when per capita output and per capita investment are cointegrated. Applying the proposed method to the post-war data of major industrial countries, it is found that a disturbance to investment share does not produce a positive long-run effect in each of the four countries—France, Italy, Japan and the UK—in which per capita output and per capita investment are cointegrated. The evidence is unfavorable to the class of endogenous growth models.

Abstract:
This note studies the optimal production and hedging decisions of a competitive international firm that exports to two foreign countries. The firm as such faces multiple sources of exchange rate uncertainty. Cross-hedging is plausible in that one of these two foreign countries has a currency forward market. We show that the separation theorem holds in that the firm’s production decision depends neither on its risk attitude nor on the underlying uncertainty. We further show that the firm’s optimal forward position is an over-hedge, a full-hedge, or an under-hedge, depending on whether the two random exchange rates are strongly positively correlated, uncorrelated, or negatively correlated, respectively.

Abstract:

This paper analyzes the impact of market liberalization on gender wage differentials and discrimination against women in urban China at the beginning of the 90s. The observed stability in the overall gender wage gap between 1988 and 1995 is shown to result from a complex set of evolutions across enterprises, earnings distributions and time. Our results highlight the interplay of opposing forces, economic reforms contributing to changes in managers’ behaviors in different dimensions. On the one hand, by bringing more competition, liberalization favored a reduction in discriminating behaviors in both urban collectives and foreign-invested enterprises; on the other hand, by relaxing institutional rules, it led to a loosening of the government’s egalitarian wage setting policies, thus leaving space for discrimination to arise in state-owned enterprises.

Abstract:

Using a panel data of both audit firms and listed firms in China from 2001 to 2003, we examine the continuous relation between audit firm size and audit quality in China’s relatively competitive market for publicly listed firms. We find that larger auditors are more likely to issue modified opinions than smaller auditors. We also find that larger auditors tend to enjoy a significant audit fee premium. These results indicate the existence of not only a positive but also a continuous relation between audit firm size and audit quality in the market. We further examine the relation between the size of auditors and the listed firms’ corporate governance and offer evidence that the size of auditors is related positively to quality of corporate governance. The results suggest that auditing is a complement to various internal corporate control mechanisms in the listed firms.

We obtain three results. First, we offer evidence that the likelihood of forced CEO turnover is related to the incidence of negative earnings but not to industry-adjusted return on asset. Second, we document some improvement in accounting performance following CEO turnover, but the extent of the improvement is smaller and less significant than what has been documented for U.S. and Japanese enterprises. Third, we show that there is no significant relation between CEO turnovers and stock price performance.

Abstract:

The Washington Consensus suffers from fundamental inadequacies, and that a more comprehensive framework of the economic process is needed to guide the formulation of country-specific development strategies. The following five propositions summarise the set of interrelated arguments made in this paper:

 

1. The Washington Consensus was based on a wrong reading of the East Asian growth experience. This explains why some observers have called the trade regimes of Korea and Taiwan in the 1965-1980 period “free trade regimes” even though they featured extensive import tariffs and export subsidies.

2. There have been two phases to the Washington Consensus doctrine. The mantra of the first phase (Washington Consensus Mark 1) is “get your prices right”, and the falsification of this first mantra led to the emergence of the second phase of the Washington Consensus doctrine. The new mantra from the Washington Consensus Mark 2 is “get the institutions right”. The danger is that an elastic definition of the term “institutions” will render the current mantra intellectually vacuous.

3. While central planning went overboard in suppressing the private market economy, the Washington Consensus runs the danger of denying the state its rightful role in providing an important range of public goods. The Washington Consensus also runs the danger of denying the limitations of self-help in the case of sub-Saharan Africa by overlooking the possibility of poverty traps.

4. The Washington Consensus does not understand that the ultimate engine of growth in a predominantly private market economy is technological innovations, and that the state can play a role in facilitating technological innovations. The Washington Consensus is too hooked upon trade-led growth to acknowledge that science-led growth is becoming even more important.

5. The Washington Consensus does not recognize the constraints that geography and ecology could set on the growth potential of a country. For example, the trade-led growth strategy of East Asia cannot work with the same efficiency for a landlocked country. Foreign direct investment is also less likely to go to places that are malaria-infested.

Abstract:

There exist three views in the literature on the efficiency of state-owned versus private firms: competition, ownership, and governance. Each view emphasizes on one aspect while ignoring others. In this paper, we use a unique World Bank survey data of 736 Chinese firms across seven sectors and five cities from 1996 to 2001 to assess the relative importance of the above three views, both independently and jointly. It is found that when examined independently each determinant matters in explaining the efficiency of our sample firms; however, when they are jointly examined, ownership type and corporate governance are relatively more important, while the competition effect is less significant generally. We also find there is some degree of substitutability between two pairs: privatization and corporate governance, and privatization and competition. These results suggest that the three views are indeed incomplete, and a complete package requires some combination of these determinants. We also find that non-SOEs seem to have certain advantage in some governance mechanisms than SOEs and that market competition matters greatly for SOEs but not so much for non-SOEs. These results have important policy implications for China’s on-going privatization movement and her strive for better corporate governance and market competition.

Abstract:
This paper examines the optimal futures hedging decision of a firm facing uncertain income that is subject to asymmetric taxation with no loss-offset provisions. All futures contracts are marked to market and require interim cash settlement of gains and losses. The firm is liquidity constrained in that it is forced to prematurely close its futures position on which the interim loss incurred exceeds a threshold level. The liquidity risk created by the interim funding requirement of a futures hedge is shown to proffer the firm perverse incentives, thereby making an under-hedge optimal. This under-hedging result holds irrespective of whether the firm is risk neutral or risk averse.

Abstract:

This paper examines the interaction between operational and financial hedging in the context of the competitive firm under output price uncertainty. The firm is endowed with an abandonment option in that its production decision is made after the true realization of the random output price has been observed. If the realized output price is less than its marginal cost, the firm optimally exercises its abandonment option and ceases from production. Otherwise, the firm lets its abandonment option extinguish and produces at its capacity. The existence of the abandonment option is shown to induce the firm to opt for a concave payoff risk-sharing rule that can be perfectly replicated by writing call options with a single strike price set equal to the marginal cost. We derive necessary and sufficient conditions that ensure a positive (negative) effect of operational hedging via the abandonment option on the firm’s optimal operating leverage. In contrast, we show that the effect of financial hedging via customized exotic derivatives on the firm’s optimal operating leverage is unambiguously positive. These results suggest that the interaction between abandonment options and exotic hedging is multi-dimensional and deserves further scrutiny.

Abstract:
This paper examines the production and hedging decisions of a globally competitive firm under exchange rate uncertainty. The firm is risk averse and possesses export flexibility in that it can distribute its output to either the domestic market or a foreign market after observing the realized spot exchange rate. To hedge against its exchange rate risk exposure, the firm can trade fairly priced currency call options of an arbitrary strike price. We show that both the separation and full-hedging results hold if the strike price of the currency call options is set equal to the ratio of the domestic and foreign selling prices. Otherwise, neither result holds. Specifically, we show that the optimal level of output is always less than that of an otherwise identical firm that is risk neutral. Furthermore, an under-hedge (over-hedge) is optimal whenever the strike price of the currency call options is below (above) the ratio of the domestic and foreign selling prices.

Abstract:
This paper proposes a theory of group formation based on the motive to seek informed opinion. Because an individual evaluates whether others are informed or not using his own priors, he identifies people with similar beliefs to be more informed than those with different beliefs. The result is an equilibrium in which society is divided into distinct groups, with members of each group believing that their own group is superior. When individuals have overconfidence in their ability to discern uninformed opinion from informed opinion, learning from like-minded peers can lead to persistent bias within a group.

Abstract:

In this paper we have addressed the nature of China’s politicized capitalism emerging from market transition. We have specifically sought to investigate whether the pattern of interventions by the communist party and government bureaus in the corporate governance of for-profit firms represents a stable equilibrium in the institutional evolution of China’s mixed economy. We have yielded two major findings. First, we confirm the developmental state view that the quality of state actor interference is actually contingent on state structures, incentives and constraints. In this sense, we provided evidence that overall party intervention is inferior to government intervention and that the quality of state actor involvement in economic transactions at the firm level is determined by the functional aptitude of state actors. Second, our estimates do not support the widespread belief in the existence of a “helping hand” of state intervention at the firm level in China. In contrast to the common view that close state-firm relations have actually contributed to China’s remarkable growth trajectory (Walder 1995, Frye and Shleifer 1997), our results suggest that politicized capitalism is not associated with significant beneficial input in China’s listed firms and is therefore unlikely to represent a stable institutional equilibrium.

Abstract:
Two-color partial rainbow options, or TCPRO for short, are proposed. Such options allow holders to choose between the two underlying vanilla options at a specifed time before expiry. Examples of benefits of TCPROs to both holders and issuers are given. Pricing formulae for such options are derived. The extra premium due to the choosing feature of a TCPRO, called the price of choice, is a nonnegative decreasing function of the correlation coeffcient of the two underlying assets and the remaining time to choosing. Numerical results are obtained to show that while TCPROs are more valuable than the underlying vanilla options, their risk parameters such as delta and gamma are smaller.

Abstract:
We offer evidence that variations in firm idiosyncratic volatility are related to both behavior and fundamental factors. Using Japanese data from 1975 to 1999, we document that both institutional herding and the absolute value of firm earnings are positively related to idiosyncratic volatility. We find that institutional herding explains about 10% of the cross-sectional variation in idiosyncratic volatility, more than firm earnings, which account for less than 1%. Moreover, we reject the hypothesis that institutional investors herd toward stocks with high idiosyncratic volatility and systematic risk. We present preliminary results on the co-movement of dispersions of change in institutional ownership and return-on-asset with the market aggregate idiosyncratic volatility in the Japanese market. Our results, when relating to evidence on the U.S. market, suggest both investor behaviors and stock fundamentals may help explain the time-series pattern of market aggregate idiosyncratic volatility.

Abstract:

In this paper, we examine the dynamics of the price change-trading volume relation at the aggregate market/index level. We introduce the use of a novel “volume dispersion” measure designed to proxy for the variability in firm-specific information flows across securities that comprise the market. Our results suggest that the price change-volume relation can be strengthened by the introduction of this measure. We also offer evidence of a positive relation between market volatility and trading volume and a negative relation between market volatility and volume dispersion. Furthermore, we demonstrate that lagged values of market level trading volume and volume dispersion can predict the next day’s index level volatility. Our findings remain robust when the implied volatility of the S&P 100 index options is used in the analysis. This suggests that index option traders need to pay close attention to both aggregate market level trading volume and volume dispersion to better capture the dynamics of daily market volatility.

Abstract:
The short-sales practice in the Hong Kong stock market distinguishes itself in that only stocks on a list of designated securities, revised from time to time, can be sold short. By analyzing the price effects around the changes of the list, we find that short-sales constraints tend to cause stock overvaluation and that the overvaluation effect is more dramatic for individual stocks where wider dispersion of investor opinions exist, which are consistent with Miller (1977)’s intuition and other optimism models. We also document higher volatility and less positive skewness of individual stock returns when short sales are allowed.

Abstract:

This paper conducts a two-stage analysis to demonstrate that earnings management in China’s listed companies is mainly induced by controlling owners’ tunneling activity. In the first stage, we relate our analyses to prior research on Chinese listed companies which has documented their strong incentives to manage earnings in order to meet certain return on equity (ROE) thresholds. We identify tunneling evidence in two scenarios where such practice has been most conspicuous. In the second stage, we examine systematic differences in earnings management across the universe of China’s listed companies during 1999-2001. We provide cross-sectional and timeseries evidence showing that firms with higher corporate governance levels tend to have less earnings management. Our empirical findings although not being able to completely exclude other theories, strongly suggest that agency conflicts between controlling shareholders and outside investors are the main stimuli of earnings management in China’s listed companies.

Abstract:

This paper studies the relationship between the governance mechanisms and the market valuation of publicly listed firms in China empirically. We construct measures for corporate governance mechanisms and measures of market valuation for all publicly listed firms on the two stock markets in China by using data from the firm’s annual reports. We then investigate how the market-valuation variables are affected by the corporate governance variables while controlling for a number of factors commonly considered in market valuation analysis. A corporate governance index is also constructed to summarize the information contained in the corporate governance variables. The index is found to have statistically and economically significant effect on market valuation. The analysis indicates that investors pay a significant premium for well-governed firms in China, benefiting firms that improve their governance mechanisms.

Abstract:

This paper develops a fairly general empirical procedure to trace out the extent of profit disguising and examine the motives behind it. Applying the methodology to the National Bureau of Statistics of China (NBS) database which covers more than 20,000 large-and mediumsized industrial firms in China for 1995-2002, we find (i) there is a profit-disguising propensity order by ownership in China (from the weakest to the strongest) — foreign invested firms < Hong Kong or Taiwan firms < state-owned enterprises < mixed firms < collective firms < private firms. Specifically, we find that, based on a conservative estimation, the private firms in China on average disguise 18.5% more profits than the state-owned enterprises and 37.4% more profits than foreign firms; (ii) firms with tighter financing constraints reveal stronger tendency to disguise profit; and (iii) smaller firms tend to disguise more profits. These results suggest that tax evasion, and incentive to overcome financing constraints, together with distorted corporate behavior caused by insecure property rights and weak institutions, account for Chinese firms’ profit disguising. We also find that Chinese firms’ profit disguising lies principally on revenue rather than cost.

Abstract:

When there is competition for the control over a listed firm, the contestants have to bid for it by committing their own resources to prop up the firm, which benefits ordinary outside shareholders. The existing literature has not provided clear evidence of propping and the conditions under which propping prevails. The evidence for the benefits of having a market for corporate control is also lacking. This paper fills the aforementioned void by presenting a case study of China’s emerging corporate control market. We examine why a typical piece of bad news – a listed firm gets into financial trouble and is designated a special treatment (ST) firm by the regulatory authorities – could have generated overwhelmingly favorable market reactions. Our analysis shows that the firms’ 31.8 percentage points of abnormal stock market performance over the two years after being designated ST reflects the price paid by their controlling shareholder (incumbent or entrant) in resources commitment in order to gain control over and save the firms. We find that the controlling shareholders’ propping is more conspicuous in firms where the competition for the control rights is tougher and the size of control benefits is larger. We also suggest an innovative way to estimate the private benefits of control and find that they are on average 33.5% of firm value in China.

Abstract:
Following the analytical approach suggested in Campbell (1994), this paper considers a baseline real-business-cycle (RBC) model with endogenous labor supply. It is observed that the coeffcients in the loglinear equations approximating the equilibrium are related to the fundamental parameters in a relatively simple manner. These equations can be utilized to obtain the closed-form approximate solution with ease and to demonstrate the properties (say, uniqueness) of the solution with clarity. Furthermore, comparative static results can be confirmed analytically (by, for example, straightforward differentiation). We believe that (at least some of) these conclusions can be generalized to more complicated RBC models.

Abstract:

Traditionally, belief in the Chinese Zodiac promotes the superstition that the timing of one’s birth determines one’s fate. Adherence to this belief has resulted in increased birth rates during Dragon years and, hence, problems in the logistics of providing certain public goods and services (such as schools and medical services) by governments. Despite the possible economic impacts of this superstition on society, no previous study has attempted to test its validity. Using the 1991 and 1996 Hong Kong census data sets, as well as the standard “Return-to-Education” methodology, we do not find any evidence for this pervasive superstition.

Abstract:

Liquid markets for debt securities exist comprehensively in no East Asian economy other than Japan, even though short or medium-term bonds are issued in most and Asian borrowers are established (though generally not prolific) international issuers. Today’s markets provide a borrowing medium (not always effectively) for Asian governments, financial institutions and some companies, but investor activity is closely correlated with bank credit creation. Above all, the region’s markets provide no real guard against crisis or contagion, nor act as a balance to banking systems susceptible to distortion and event risk. Asia’s economies may not suffer general capital shortages but poor resource allocation is pervasive and would be greatly improved by efficient national and regional financial markets.

This paper is concerned with markets for tradable debt securities, with the impediments to their proper functioning and with the value of structured finance techniques to expand general usage in Asia’s debt markets. Seven years after its most profound financial crisis, Asia risks new contagion from any similar, unforeseen loss of confidence. Active debt capital markets would help limit such risks. The world’s foremost bond markets developed as a result of intense national needs, and while economic growth will inevitably lead to greater bond issuance and trading this will be insufficient for the region’s wider requirements without official sponsorship of active cooperative market reform.

The paper concludes with three linked policy proposals: a matrix of steps to remove legal, fiscal, regulatory or systemic obstacles or omissions that severely hinder market usage; measures to encourage the development of a unified regional offshore market for local and major currency risk; and the concept of a regional body to promote the creation of assetbacked securities on a scale not previously contemplated.

Abstract:
This paper examines the behavior of the competitive firm under price uncertainty in general and the hedging role of futures spreads in particular. The firm has access to a commodity futures market where unbiased nearby and distant futures contracts are transacted. A liquidity constraint is imposed on the firm such that the firm is forced to prematurely close its distant futures position whenever the net interim loss due to its nearby and distant futures positions exceeds a threshold level. This paper shows that the liquidity constrained firm optimally opts for a long nearby futures position and a short distant futures position should the firm be prudent, thereby rendering the optimality of using futures spreads for hedging purposes. This paper further shows that the firm?s production decision is adversely affected by the presence of the liquidity constraint.

Abstract:

Central banks have been criticised for changing interest rates “too little, too late”. While this pattern arises in a simple model in which policymakers are exposed to uncertainty about the optimal level of interest rates and set the policy rate in steps, we show that the problem is exacerbated if a policy committee takes decisions by consensus rather than by a vote. Policy rate changes are moreover rarer under a consensus procedure and, when there is an adjustment, the policy rate is more frequently adjusted by several steps at a time.

Abstract:
This paper estimates a small structural model of the Hong Kong economy using quarterly data for the period 1990 to 2002 on the output gap, CPI, property price and import price inflation, the nominal interest rate and the nominal effective exchange rate. We find that fluctuations in the output gap are mainly driven by external factors, while CPI inflation also is affected by domestic shocks. The paper then provides counterfactual simulations of how the economy would have evolved under alternative monetary arrangements. To that end, we simulate the model using an interest rate reaction function of the Taylor type and a Singapore-style reaction function of the nominal effective exchange rate. It appears that these alternative regimes might have led to different inflation trajectories but would have had a limited impact on the path of economic activity.

This paper uses unobserved components analysis to estimate the natural rate of unemployment in Hong Kong. We assume that the natural rate follows a random walk and is a determinant of the Beveridge curve. We find that the natural rate has increased since the 1990s but nevertheless lies clearly below the actual rate of unemployment. This indicates that unemployment is likely to decrease in the near future.

Abstract:
SARS is the first deadly infectious disease of the 21st Century. It started in Guangdong of China in November 2002, and by August 2003, it had spread to 29 countries and 3 regions, with a cumulative total of 8,422 cases and 916 deaths. This paper describes the spread of the disease in Hong Kong and discusses its impact on the economy. SARS was an unexpected negative shock. The most significant negative effects were on the demand side, with local consumption and the export of services related to tourism and air travel severely affected in the short run. The economy did not experience a supply shock, as the manufacturing base in the Pearl River Delta was unaffected, and goods continued to be exported through Hong Kong normally. Initial alarmist reports and estimates about the negative economic impacts were not borne out. Fear and panic subsided quickly once the outbreak was under control, and the economy rebounded rapidly.

Abstract:
We develop an equilibrium model to analyze the role of the media in electoral competition. Policy payoffs in the model are state dependent. We show that voters cannot infer the state directly from off-equilibrium party policies. As a result, party policies do not converge to the median voter’s ideal policy when the media report only party strategies. News analyses that convey information about the state allow voters to identify the party that serves their interests. Competition for positive news coverage causes political parties to adopt more centrist policies. In equilibrium voters interpret the news srategically. Mass media that are likely to have the same policy preference as the median voter are more effective in promoting electoral competition, resulting in greater policy convergence. However, since voters are rational, media that are more biased need not be less effective.

Abstract:

In this paper, we use a version of the Dixit-Grossman-Helpman (1997) common agency model and apply the lobbying framework to exchange rate policies. In particular, we formalize Ron McKinnon’s idea that the appreciation of the Japanese yen in the past was due to trade pressure applied by the U.S. government. We extend the theory to examine the case where the Japanese firms are modeled as a coalition of shareholders and incumbent employees (Aoki 1988). We conclude by pointing out that this approach is applicable and relevant to the current disputes on the level of the Yuan exchange rate between the U.S. policymakers and the Chinese government.

Abstract:
Instrumental variables (IV) estimates of the effect of fertility on female labor supply have only been able to identify the causal effect of second and higher-parity children. This study uses exogenous variation in fertility caused by the Chinese lunar calendar to identify the effect of the first child. Additionally, weighting formulas are presented to interpret IV estimates as weighted average treatment effects in the case of multiple endogenous variables, which are useful when children vary in intensity by both number and age. The effect of the first child is found to be much greater than that of other children.

Abstract:

There is a large literature on the determinants of foreign direct investment. In recent years, China emerges as the largest recipient of foreign direct investment. Is China taking direct investment away from other Asian economies? Theoretically, a growing China can add to other countries’ direct investment by creating more opportunities for production networking and by raising demand for raw materials and resources. At the same time, relatively low Chinese labor costs may lure multinationals away from other Asian sites when multinationals consider alternative locations for low-cost export platforms. In this paper, we explore this important issue empirically. We use data from eight Asian economies (Hong Kong, Taiwan, Republic of Korea, Singapore, Malaysia, Philippines, Indonesia, and Thailand) from 1985 to 2001 and control for the determinants of their inward foreign direct investment (FDI). We then add China’s FDI inflows as an indicator of the “China Effect”. Due to possible simultaneity between China’s and the Asian countries’ inward FDI, we use fixed effects as well as random effects simultaneous equation models to estimate the “China Effect”. We have four results: (1) The level of China’s FDI is positively related to the levels of other Asian economies’ inward direct investments; (2) the level of China’s FDI is negatively related to these economies’ shares of total Asian inward FDI as well as shares of total FDI inflows to the developing countries; (3) the China Effect on the Asian countries’ shares of the world inward FDI is mixed, minimal and not significant; and (4) the “China Effect” is not the most important determinant of inward direct investments to these economies. In particular, corporate tax rates, the level of corruption, and openness to trade have more influential effects on FDI inflows.

Abstract:
This paper investigates the possibility of hedging discrete stochastic jumps and their tradeoffs in guaranteed funds under discrete dynamic hedging. Since a guaranteed fund price process is composed of diffusion and jump process, its expected rate of return is above the risk-free rate of interest. When delta dynamic hedging occurs at discrete instants, the rate differential will be manifested in non-zero expected hedging errors. We employ the dynamic guaranteed fund as our example, whose exotic fund structure excludes the possibility of static hedge. We derive a pricing model and develop hedging formulas for discrete dynamic guaranteed funds. We show our discrete-time delta hedging formulas induce smaller hedging errors than those based on applying the continuous-time hedging formula of Gerber and Pafumi (2000) at discrete instants. Nevertheless, this discrete-time model still incurs significant negative expected hedging errors induced partly by the guarantee jumps. We introduce a gamma-adjusted delta hedging strategy. The simulation results indicate that the strategy can effectively improve the discrete hedging performance of dynamic guaranteed funds.

Abstract:

Is China taking direct investments away from other Asian economies? Theoretically, a growing China can add to other countries’ direct investments by creating more opportunities for production-networking and raising the need for raw materials and resources. At the same time, the extremely low Chinese labor costs may lure multinationals away from other Asian sites when the foreign corporations consider alternative locations for low-cost export platforms. In this paper, we explore this important issue empirically. We use data for eight Asian economies (Hong Kong, Taiwan, Republic of Korea, Singapore, Malaysia, Philippines, Indonesia and Thailand) from 1985 to 2001 and control for the determinants of their inward direct investment. We then add China’s inward foreign direct investment as an indicator of the “China Effect”. Due to issues of simultaneity, we use a random effects simultaneous equation model to estimate our coefficients. We have three results: (1) The level of China’s foreign direct investment is positively related to the levels of these economies’ inward direct investments; (2) the level of China’s foreign direct investment is negatively related to the direct investments of these economies as shares of total Asian foreign direct investments; (3) The China effect is not the most important determinant of the inward direct investments of these economies. Policy and institutional factors such as openness, corporate tax rates and corruption can be more important.

Abstract:

Turn taking is observed in many field and laboratory settings. We study when and how turn taking can be supported as an equilibrium outcome in a class of repeated games, where the stage game is a symmetric two-player mixed-interest game with asymmetric joint-payoff-maximizing outcomes that may or may not be Nash equilibria. We consider the “turn taking with independent randomizations” (TTIR) strategy that achieves the following three objectives: (a) helping the players get onto a joint-payoff-maximizing turn-taking path, (b) resolving the question of who gets to start with the good turn first, and (c) deterring defection. The TTIR strategy is simpler than those time-varying strategies considered in the Folk Theorem for repeated games. We determine conditions under which a symmetric TTIR subgame-perfect equilibrium exists and is unique. We also derive comparative static results, and study the welfare properties of the TTIR equilibrium.

Abstract:

This paper examines the behavior of the competitive firm under output price uncertainty when the firm is endowed with an abandonment option and has access to a forward market for its output. When the realized output price is less than its marginal cost, the firm optimally exercises its abandonment option and ceases from production. The firm lets its abandonment option extinguish, thereby producing up to its capacity, only when the realized output price exceeds its marginal cost. The ex post exercising of the abandonment option as such convexifies the firm’s ex ante profit with respect to the random output price. We show that neither the separation theorem nor the full-hedging theorem holds in the presence of the abandonment option. The firm under-hedges its output price risk exposure in the forward market wherein the forward price contains a non-positive risk premium. When the set of hedging instruments is expanded to include options, we show that both the separation and full-hedging theorems are restored. We further show that the firm prefers options to forwards for hedging purposes when both types of contracts are fairly priced.

Abstract:
We analyze the role played by the most favored nation (MFN) principle in accession negotiations in the WTO. We make use of a model with three countries trading in three goods. Two countries of similar size are existing members of WTO and the third country applies to join it. To capture the existing WTO accession procedure, we assume there to be a series of bilaterial sequential bargaining. We found that not only does the applicant gain a higher share of the total surplus than the existing members, its absolute gain is also higher under MFN. Even when compared with multilateral Nash bargaining, bilateral sequential bargaining with MFN favors the applicant both relatively and absolutely. The result can be easily extended to an N-country case.

Abstract:

Frequent bank recapitalization is the biggest threat to China’s fiscal solvency and macroeconomic stability. Our calculations conclude that the forthcoming second recapitalization since 1997 is the last one that China can afford. Even then, fiscal solvency and macroeconomic management requires that the state continues keeping interest rates artificially low in order to avoid reducing the present fiscal stimulus to accommodate the servicing of the bonds issued for the bank bailout. In short, China faces a difficult tradeoff between the maintenance of fiscal stimulus to keep growth on track and the promotion of financial market development via recapitalizing the state banks, splitting them up and privatising some of them, liberalising the establishment of private financial institutions, improving prudential monitoring and enforcement, and deregulating interest rates.

Abstract:
Through individuals prefer to join groups with high quality peers, there are also advantages from being high up in the pecking order within the group. We show that sorting of agents in this environment results in an overlapping interval structure in the type space. Segregation and mixing coexist in a stable equilibrium. A greater degree of egalitarianism within organizations leads to greater segregation across organizations. Policies that are effective for lower-quality organizations to attract talent may be counterproductive for higher-quality organizations to retain talent.

Abstract:
We examine the impact of the introduction of no-fault divorce on the age at first marriage in the context of a model where everyone has a different value of marriage. Our model predicts that the spread in the age at first marriage should become smaller when legal regimes switch from fault to no-fault. We test this hypothesis with a large data set of American marriage records from 1970 to 1995. We find support for our prediction–the standard deviation of the log age at first marriage drops by approximately eight percent with the introduction of no-fault divorce. Given our model, the median and mean age of first marriage act as indicators of welfare over the transition. We find that the median and mean age at first marriage drop slightly, suggesting that the median person is slightly better off.

Abstract:
This paper analyses the determinants of wage differentials among enterprises of different ownership in urban China in 1995, using an extended version of Oaxaca-Blinder decomposition methods. We find strong evidence of a multi-tiered labor market in China, pure ownership-related differences and differences in hours worked being the major determinants of observed wage gaps. Our results highlight different paying schemes among domestic enterprises as well as between domestic and foreign enterprises. We stress the dual nature of domestic production structures, workers in central state-owned enterprises being highly protected as compared to other domestic enterprises. We also emphasize that foreign-invested enterprises provide higher total annual earnings mostly at the cost of a much longer working time and do not offer higher hourly wages than state-owned enterprises. Our results provide explanations for the very low labor mobility observed out of the large overstaffed SOEs in the 90s, which has led to massive lay-offs at the end of the decade.

Abstract:
In 1989, the Hong Kong government embarked on a program to increase the provision of first-year first-degree places from 7 percent to 18 percent of the 17-20 age cohort. The expansion of tertiary education represents a large and exogenous increase in supply of university graduates to the territory. This paper measures the labor market effects of the expansion program by studying the changes in earnings premium for university graduates. Two alternative hypotheses, crowding and quality effects, are identified to explain why the earnings premium shrinks. The results support the view that the declining quality of university graduates is the prime candidate for the declining earnings premium.

Abstract:
Most central banks change interest rates in steps of 25, 50 or 75 basis points at scheduled dates. This paper presents a model that determines optimally the step size and the frequency of policy decisions. In contrast to the existing literature we argue that the size of interest rate changes is chosen to help focus policy decisions, which we assume are taken by a Monetary Policy Committee. Moreover, we assume that the preparations of policy meetings are costly and that decisions therefore are scheduled such that an interest rate change is likely. The analysis indicates that the step pattern depends on the variability of the unobserved optimal level of interest rates, policymakers’ difficulties observing it and their preferences. The model expands the literature by predicting occasional policy rate adjustments by two steps at a time.

Abstract:
Will the formation of free trade areas lead to lower wages? Much of the literature on linking globalization and the labour market suggest that increased openness can lead to lower wages. In this paper we investigate empirically the case of Canada, which signed a free trade agreement with the United States in 1988. A significant portion of trade between the United States and Canada is intra-industry in character. In Krugman’s (1981, 1982) monopolistically competitive intra-industry model, trade liberalization actually has an ambiguous impact on wages. Based on Krugman’s model, we provide an empirical study relating Canadian wages to workers’ characteristics, industry characteristics, and tariff and non-tariff barriers. Among other findings, we show that freer intra-industry trade can raise workers’ wages. This result persists even after the endogeneity of trade barriers is taken into account.

Abstract:
Markets for debt securities exist in a comprehensive way in no Asian economy other than Japan, even though short or medium-term bonds have been issued in almost all and Asian borrowers are established (though not prolific) international issuers. The markets provide no more than a simple borrowing medium for governments, banks and some companies, while investor activity is closely correlated with banking sector credit creation. Above all, the region’s unfinished markets provide no guard against crisis or contagion, nor act as a balance to banking systems that are susceptible to distortion and event risk. Insufficient effort has been made to encourage activity by institutional investors.

This paper is concerned with markets for tradable debt securities; and with the value and appropriateness of stuctured finance techniques to expand general usage of Asia’s debt markets. The paper examines the condition of the domestic and offshore debt capital markets for Asia-Pacific risk. It traces common patterns of development among the established and nascent public debt securities markets in the region, and looks at the dynamics that will affect these markets in the medium term. Last, it seeks to identify whether Asian markets can be made to accommodate continuous issuing and trading activity typical of advanced economies, and to consider the associated advantages and considerations.

Abstract:
Ever since Shanghai announced in April 1990 its plan to develop the Pudong New Area, and its ambition to re-emerge as a major international financial, commercial and shipping centre by 2010, the traditional Tale of Two Cities about the rivalry, real or imagined, between Hong Kong and Singapore has gradually given way to a new one featuring Shanghai vs. Hong Kong. Shanghai’s recent successful bid for the 2010 World Expo, in contrast to Hong Kong’s failure to capture even the Asian Olympics, is regarded by many as pregnant with symbolic significance.

Abstract:
Currency boards are subject to runs if the foreign currency reserve is insufficient to back the convertible money supply. We construct a simple model capturing the main features of a currency board to analyze a government’s decision to maintain or abandon a currency board based on the costs and benefits. We show how pre-specified commitments can enhance the credibility of a currency board and avert runs in times of uncertainty, and determine what the optimal reserve commitment should be. If there exists asymmetric information on the government’s resolve, the government can use commitments as a costly signal to induce a separating equilibrium. The model can be adapted to analyze other hard-fixed exchange rate systems such as dollarizations and monetary unions. We illustrate the implications of our model in terms of the recent success in Hong Kong and possible remedies for Argentina.

This paper examines the qualitative impact and the degree of effectiveness of several labor market policies when domestic union’s wage response and economic integration are explicitly taken into account. The employment policies considered include payroll tax cuts, unemployment benefits cuts, aggregate demand expansion and wage subsidies. It is shown that with endogenous wages and an open economy, these policies can in some cases become more potent. But in other instances, they become less effective. In fact, under some conditions derived in this paper, employment policies can even be counterproductive, leading to a drop in domestic employment.

Abstract:

In this study we use a data set that provides information on Chinese Communist Party grassroots organizations’ political control over decision-making in China’s listed firms. Specifically, we examine how different types of shareholders affect (1) the party’s level of decision-making power and (2) the performance implications of party control for firm performance. We obtain two major results. First, we find that the proportion of shares held by domestic individual shareholders is negatively related to the party’s level of decision-making power. Second, we find that the existence of large institutional investors tends to mitigate the negative performance effect of party control. Our results suggest that both the exit and the voice channel are effective at depoliticizing China’s listed firms and improving their performance. This study both addresses an important corporate governance issue relevant to China’s listed firms and offers interesting information in terms of comparative studies of corporate governance and reform strategies in transitional economies.

Abstract:

This study examines the performance implications of the involvement of grassroots organizations of the Chinese Communist Party (CCP) (hereafter referred to as local party committees) in the decision-making of China’s listed firms. We obtained two results. First, we show that the decision-making power of local party committees relative to the largest shareholders is positively associated with firm performance. This suggests that party control helps contain the largest shareholders’ agency problems and that the existing level of party control is insufficient when viewed from the perspective of controlling the largest shareholders. Second, we show that the decision-making power of local party committees relative to managers is negatively associated with firm performance. This suggests that political costs associated with party control over managers is more detrimental to firm performance than are managers’ agency problems and that the existing level of party control is excessive when viewed from the perspective of controlling managers. On net, our results indicate that the existing level of party control is excessive and that reducing the decision-making power of local party committees tends to improve the performance of China’s listed firms.

Abstract:
This paper examines the geographic determinants of U.S. and Japanese direct investment in China for the years 1990-2001. We use a random effect panel model of estimation to study their determinants. Four results emerge from our empirical study. First, the size of the domestic market matters. This is true in all our regressions. Thus U.S. and Japanese firms locate in China partly to sell in the Chinese market. Second, the share of manufacturing output accounted for by state-owned enterprises (SOEs) is negatively related to both U.S. and Japanese direct investments. This variable potentially captures all the formal and informal barriers that may exist against foreign investors. A large share of output by SOEs signal to the foreign investors that economic reforms are still far from complete and foreign investors should expect to face difficult political and economic challenges in that region. Thus as economic reforms deepen and spread to the interior and the western parts of China, U.S. and Japanese firms will increasingly migrate to those regions. In this respect, economic reforms generate double dividends: they are inherently efficient-enhancing and on top of that, they also attract U.S. and Japanese investors. Third, infrastructure is positively related to U.S. and Japanese direct investment flows. This includes railroads as well as roads. Transportation matters to the manufacturing operations of U.S. and Japanese multinationals in China. Lastly, the policy variable representing the number of Economic and Technological Development Zones (ETDZs) is also conducive to attracting Japanese and U.S. investment.

Abstract:

This paper embeds product market search in an AK growth model to study the effects of search frictions on market structure, capital accumulation, and long run growth. The basic hypothesis is that search frictions, in giving rise to market power, result in higher prices and lower output levels. The falling demand for capital stemming from firms cutting back output then lowers the interest rate, dampening capital accumulation and slowing down growth. A decline in search frictions sets the process in reverse, eventually speeding up growth through the change in market structure. In the meantime, the stock market values of firms could fall.

Abstract:
How may the low search cost in the new economy affect innovation and new product introduction? The usual model of product market search suggests that a low search cost can turn out to be detrimental to innovation and new product introduction as the low search cost erodes firms’ market power, attenuating the profit from innovation. This usual model, however, misses the important dimension of product market search that how often it pays to search depends on the pace at which new products are introduced. This paper studies a model of monopolistic competition with costly search, where the point of departure is that of a fixed cost of a shopping trip. With this fixed cost, the optimal frequency of search is tied to the pace at which new products are introduced. In this environment, a low search cost could turn out to be favorable to innovation. At a low search cost, consumers search more often, speeding up the diffusion of new products and possibly resulting in higher profits for firms, despite the erosion of market power.

The paper presents a model of team production motivated by the stylized facts we found from a sample of 200 joint venture contracts. The model incorporates the revenue-sharing contract into the Property-Rights and the Transaction-Cost Theories of the firm, and emphasizes the impact of expropriation. Joint control can be optimal as well as unilateral control. Our econometric analysis of the revenue-sharing and control arrangements offers strong support to our Property-Rights-Theory motivated model with self investment but rejects that with cooperative investment. The Transaction-Cost-Theory motivated model leaves some important empirical findings unexplained. Our findings reject some existing theories of joint ownership.

Abstract:
We consider a two-sided, finite-horizon model of search and matching with heterogeneous types on both sides of the market. The quality of the pool of potential matches deteriorates as agents who have found mutually agreeable matches exit the market. With automatic participation of all agents in each round, the market performs a sorting function in that more attractive types of agents have a chance to meet and match with their peers in earlier rounds of the market. If agents incur an arbitrarily small cost in order to participate in each round, however, the market completely loses its sorting function as all agents rush to participate in the first round and match with anyone they meet.

Abstract:
In many occupations, reputation or past performance affects the demand for a worker’s output, creating an incentive to invest in reputation early in a career. This results in a tendency for superior workers to start their career in the mainstream market. The intuition is that, for high ability workers, the returns to investing in reputation is larger in the mass market, while less able ones would avoid the more competitive mainstream by developing their specializations in the fringe market. Some mainstream workers may enter the fringe market once the motive to invest in reputation diminishes later in their careers, but less able workers who start in the fringe are seldom able to return to the mainstream. These results are empirically testable and have potential implications for product markets as well.

Abstract:
The observation that a worker has a family friendly job reflects both the worker’s decision to search for such a job and employer’s decision to provide it to that worker. Previous research estimating the determinants of family friendly work practices has been severely limited by the inability to distinguish between these two decisions. Using linked employer-employee data and partial observability probit models, this paper provides the first empirical identification of the determinants of these two decisions. In addition to confirming the role of many worker and firm chracteristics, the results are consistent with theoretical model in which family friendly work practices are valuable to workers but costly to employers. Specifically, as predicted by a hedonic model of the labour market, firms providing such practices offer lower wages, all else equal.

Abstract:

We examine the profitability of insider trading in Hong Kong between 1993 and 1997. On average, firms in Hong Kong have very concentrated ownership and insiders trade more actively and account for larger fractions of total turnover of their firms’ shares than do US insiders. Inside sellers in Hong Kong earn negligible rents; however, inside buyers earn statistically and economically significant positive mean abnormal returns. Inside buyers’ abnormal returns are especially large for firms in consolidated industries. We argue that such firms are less transparent than firms that operate in more focused businesses and, consequently, that shares of these firms are more likely to provide opportunities for insiders to trade based on privileged information.

In this study, we investigate the impact of institutional trading on the market by examining the daily relation between aggregate flow into U.S. equity funds and market volatility. We differentiate the impact of fund inflow and outflow, respectively, on the market volatility. Our empirical results show that there exists an asymmetric concurrent relationship between fund flow and market volatility: fund inflow is negatively correlated with market volatility while fund outflow is positively correlated with market volatility. We also discuss the potential explanations for our results and suggest that our results are consistent with information content differences of funds’ buys and sells.

Abstract:
We use time-series properties of changes in share turnover with GMM tests to examine the number of factors that drive changes in conditional expected time-varying volume. In the three ten-year subperiods between 1966 and 1996, we detect no more than two factors. These findings support the hypothesis that changes in conditional time-varying expected volume can be represented parsimoniously as a function of a few factors. However, whether we detect one factor (as Tkac (1999) suggests) or two factors (as Lo and Wang (1998) indicates) depends on which sample period we use, on whether we sort portfolios by turnover or returns betas, and on whether we measure those betas relative to the equal- or the value-weighted index.

Abstract:
In 2002, according to estimates by the U.S. government, the United States ran a merchandise trade deficit of US$ 103.1 billion with China. However, according to estimates by the Chinese government, the deficit was US$ 42.8 billion. It is often pointed out that as both a developing economy and an economy in transition, China lacks the resources to gather accurate trade data. While this is likely to be true in general, the trade data are likely to be of better quality than other kinds of economic data. Moreover, our research also shows that when it comes to U.S.-China trade, there are also significant problems with official U.S. export and import data. Our central claim is that neither the U.S. nor the Chinese official trade figures are completely accurate in terms of reflecting the true bilateral situation. The objective of this paper is to provide more accurate measurements of the trade imbalance for the purpose of facilitating more objective policy discussions between the two governments.

Campbell (1994) argues that a clear understanding of dynamic stochastic general equilibrium models can best be achieved by an analytical approach, and he suggests loglinearizing the Euler equation and the capital accumulation equation. Inspired partly by his approach and partly by the results of Long and Plosser (1983), this paper suggests an alternative approximate analytical solution procedure to dynamic stochastic models by loglinearizing the utility function and the capital accumulation equation. This approximate solution has a simple analytical form; thus, it is relatively easy to obtain further results based on the solution. Comparing its performance with that of the conventional method, it is further argued that the suggested solution procedure is most useful for dynamic stochastic models exhibiting endogenous growth.

Abstract:
This paper examines the recent trends, characteristics and determinants of Japanese direct investment in China. To study these issues, we first use qualitative and survey data to compare Japanese direct investment in China with similar investment in other Asian countries. We found that within Asia, China is the largest recipient of Japanese direct investment, with Hong Kong and Thailand coming in second and third. 76.5% of Japanese direct investment in China is in manufacturing. Such concentration in manufacturing is typical for Japanese investment in developing Asia, but rather unusual compared with Japanese investment in other developed countries. Almost one-third of Japanese investment in China is in electrical machinery. 40% of Japanese firms invest in China for cost reasons, while 21% say that they invest in China to expand market shares in China. In 1999, Japanese affiliates in China procure 47% of their inputs from China and sold 47% of the goods locally in China. We also examine econometrically the determinant of Japanese direct investment in various regions of China and compare these locational factors for direct investment from Hong Kong, the largest foreign investor in China. We found that Hong Kong companies place a stronger emphasis on labor costs and a smaller emphasis on labor quality compared to Japanese multinationals. In addition, Japanese firms prefer Economic and Technology Development Zones (ETDZs) while Hong Kong firms are attracted to Special Economic Zones (SEZs).

Abstract:
This paper examines the locational choices of Hong Kong and U.S. direct investments (DI) in China using a regional data set from 1990 to 1999. The results of the panel regressions show that there are various similarities and differences in the significance and the magnitudes of the determinants of DI between these two sources. Local GDP significantly affects the inflows of both types of investments, but U.S. investment is more sensitive to local demand. The lagged wage variable negatively affects both Hong Kong and U.S. investment, but Hong Kong investment is more sensitive to local labor cost. A rise in regional labor quality raises both investment inflows, but the quality index exerts a stronger influence on U.S. investment. These econometric estimates can be understood in light of two stylized facts of U.S. and Hong Kong investments in China. First, the motive of U.S. firms investing in China is primarily to sell in China, whereas Hong Kong firms tend to invest in China to take advantage of the low labor costs and then to export. Second, U.S. investments in China tend to be more capital- and skilled- intensive than those from Hong Kong.

Abstract:

Using firm level data obtained from a survey of about 800 state owned enterprises (SOEs), we investigate the extent of soft budget problem among China’s SOEs and its impact on firm performance. Using both ex ante and ex post soft budget proximate measures, we find that SOEs in China in general face soft budget constraint in the late 1980s. The majority of the firms surveyed pay tax from their after-loan payment profit. In addition, more than one third of the firms depend on government financial when they run into financial hardship to repay loans. Empirical estimation show that that firms facing soft budget constraint are more often perform better than (or as good as) the others in both the level and the change of labor productivity. One reason could be that firms with good performance are more often receive favorable treatment from government. It is often inevitable that government provide financial assistance to SOEs of some sort during economic transition. This is because market institutions are not fully developed and SOEs are still bearing additional social responsibilities. Our finding suggests that government assistance may not necessarily create immediate harmful consequences.

Abstract:

The paper provides a comprehensive overview of the policies and development of foreign direct investment during China’s economic reform in the past two decades. Deng’s opening-up policy initiated in the late 1970s attracted large and growing amount of foreign investment, first from neighboring economies and in recent years increasingly from western industrial countries. Foreign investment has played crucial role in China’s foreign trade as well as domestic industrial restructuring. Foreign investors provide China with much needed finance, especially during the early years of the reform. More importantly, foreign businesses bring with them technology, managerial skills, and international marketing experiences. Today, foreign businesses are important elements in China’s economy. With the accession to the WTO, China has become the one of the most attractive designation for cross-border investment.

Abstract:

The paper provides a comprehensive overview of China’s trade policies and development during the reform. During the past two decades, China’s trade with the rest of the world has growth with an unprecedented speed. At the same time, China achieved remarkable economic growth. China’s trade has some distinct characteristics. First of all, a large portion of China’s trade is what is called processed trade, including trade due to processing and assembly and trade due to processing with imported materials. Secondly, a large portion of China’s trade is conducted by foreign firms in China. Thirdly, China’s trade is geographically concentrated in the southeast part of the country, especially in the province of Guangdong. Fourthly, Hong Kong has played important role in China’s export expansion. A large portion of China’s export go through Hong Kong to be re-exported elsewhere.

Abstract:
This paper uses a dynamic panel estimation method to investigate the determinants of regional specialization in China’s industries, paying particular attention to local protectionism. Less geographic concentration is found in industries where the past tax-plus-profit margins and the shares of state ownership are high, reflecting stronger local government protection of these industries. The evidence also supports the scale-economies theory of regional specialization. Finally, the overall time trend of regional specialization of China’s industries is found to have reversed an early drop in the mid 1980s, and registered a significant increase in the later years.

Abstract:
When employers cannot tell whether a school truly has many good students or whether it is just giving easy grades, schools have an incentive to inflate grades to help their mediocre students. However, schools also care about preserving the value of good grades for their good students. We construct a signaling model in which grade inflation is the equilibrium outcome. The inability to commit to an honest grading policy in an environment of private information reduces the informativeness of grades and hurts the school. We also show that grade inflation by one school makes it easier for another school to fool the market with grade inflation. Hence, easy grades are strategic complements, and this provides a channel to make grade inflation contagious.

Abstract:
This paper studies the determination of split of gains among the negotiating parties (member countries and the acceding country) in a WTO accession negotiation using a sequential bargaining model. In particular, we are interested in the effect of the most-favored-nation (MFN) principle on the negotiation outcome. The MFN principle says that any tariff reduction offered by the applicant for accession has to be automatically granted to all existing members. This implies that any deal that an applicant, such as China, makes with a member can be made more unfavorable to China in subsequent negotiations. On the other hand, since China has the foresight that giving up each dollar to one country means giving up many more dollars, this would harden China’s bargaining position. Resorting to intuition alone, therefore, it is not clear whether China would benefit or be disadvantaged by the existence of MFN. Using the model, however, we find unambiguously that China’s share of surplus is more when MFN is in place.

Abstract:
This paper analyzes the within-cohort relative wages of differently-educated workers in Taiwan. In a development context, the educational composition of a population often changes more rapidly than its age composition. Younger cohorts entering the labor force in Taiwan between 1979 and 1998 received far more education than older cohorts. As a result, the return to education within younger cohorts declined dramatically. Therefore, in a development context, it is important to take educational composition into account when analyzing the relative wages of different cohorts.

Abstract:
This paper studies the effects of changes in occupational composition to changes in the overall female labor force participation rate in Taiwan. Using the Taiwanese KAP-IV and KAP-VI fertility surveys and the Taiwanese Panel Survey of Family Dynamics, the authors estimate a linear probability model of women?s labor force participation given time since marriage and initial occupation. There is a higher probability of participation after marriage for women in white-collar occupations than for those in blue-collar occupations. The former are also more likely to remain in the labor force in the presence of young children. Changes in occupational structure account for 30% of the observed increase in the female labor force participation rate from 1979 to 1998. This supports the hypothesis that changes in occupational structure during economic development play a significant part in determining overall female labor force participation.

Abstract:
This paper employs a new database, which contains the market and accounting data from more than 1000 Chinese listed companies up to the year 2000, to document the characteristics of these firms in terms of capital structure. As in other countries, leverage in Chinese firms increases with firm size, non-debt tax shields and fixed assets, and decreases with profitability and correlates with industries. We also find that ownership structure affects leverage. Different from those in other countries, leverage in Chinese firms increases with volatility and firms tend to have much lower long-term debt. The static tradeoff model rather than pecking order hypothesis seems better in explaining the features of capital structure for Chinese listed companies.

Abstract:
In this paper, we test the 2-parameter symmetric variance gamma option pricing model and the 3-parameter asymmetric variance gamma option pricing model empirically. Prices of the Hang Seng Index call options which are of European style are used as the data for the empirical test. Since the VG option pricing model is developed for the pricing of European options, the empirical test gives a more conclusive answer than previous papers which used American option data to the applicability of the VG models. The present study uses a large number of intraday option data which span over a period of three years. Sychonous option and futures data are used throughout the study. Pairwise comparison between the accuracy of model prices are carried out using both parametric and non-parametric methods. The conclusion is that the VG models are useful models for option pricing and can produce model prices which approximate observed market prices better than the Black-Scholes approach.

This paper investigates the determinants of regional specialization using a panel data set covering 32 two-digit industries in 29 Chinese regions over a period of 13 years (1985-1997), paying particular attention to the role of regional protectionism. It is found that there is less geographic concentration in industries where past profit and/or tax margins are high and where the share of employment by the state-owned enterprises is high, reflecting stronger local government protection of these industries. The evidence also supports the external-economies theory and the increasing-returns-to-scale theory, but not the resource-endowment theory, of regional specialization. Finally, the overall time trend of regional specialization of China’s industries is found to have reversed an early drop in the mid 1980s, and registered a significant increase in the later years.

Abstract:

The implementation of China’s Company Law in 1994 has been regarded as a major tool in the corporatization of China’s enterprises and establishment of a new power structure modeled on modern corporations in market economies. The law attempts to transfer decision-making power from the old party/state organizations to standard organizational bodies of modern corporations. Several observers have already claimed that the power transfer has not been complete in corporatized enterprises, but astonishingly, there have been no attempts to empirically measure the de facto enforcement of the Law and reveal the prevailing pattern of enterprise power structure. Based on a unique survey of the corporate governance structure of 248 companies listed at the Shanghai Stock Exchange, our paper seeks to bridge the gap by approaching the issue with a dual focus; first of all, we seek to reveal whether the current power distribution in China’s listed companies is actually consistent with the formal rules of the Company Law. Secondly, we highlight the role of the local party units in the evolving power structure of the companies. The paper offers a preliminary evaluation of the enforcement of the Company Law and the degree of de facto enterprise de-politicization. The results will be particularly helpful to broaden understanding of the forces and dynamics of institutional and organizational changes in China’s transitional economy.

Abstract:

Structural changes of the elite have been a particular focus of sociological and economic research since the outset of reforms in the post-communist transition countries. While most studies on elite changes focus on the relative income position as the indicator for the changing position of the old elite, we concentrate on the strength and pattern of decision-making power of China’s old elite in newly emerging economic entities like listed companies. In line with the power persistence thesis, our analysis shows that the local party committees still succeed at keeping their fingers in the decision-making process even after two decades of economic transition, due to diverse lock-in effects between party and various areas of the institutional environment. We hypothesize that the decision-making power of the local party committees is weakened by the emergence of market and private power during the economic reform and test our hypothesis by employing a survey conducted by the Shanghai Stock Exchange. This study supplements and broadens evidence to market-transition model and emphasizes private power as the major constraints on local Party power persistence in enterprise decision-making.

Abstract:

In the corporate governance literature, the notion that political interference in enterprise decision-making is detrimental to corporate performance is widespread and is buttressed by a large body of theoretical studies. However, few empirical studies support the theories these studies espouse. For our study, we construct measures with which to capture political interference in the decision-making of China’s listed companies and perform direct tests to determine the relationship between political interference in the decision-making of these companies and their performance. We offer evidence that political interference in these companies’ decision-making negatively affects their performance. This study not only addresses an important corporate governance issue for China’s listed companies but also brings together the theoretical and empirical aspects of the corporate performance implications of political interference.

Abstract:

Agency theory suggests that managerial discretion is negatively related to firm performance. In this study, we investigate how the relationship may be affected by the existence of controlling parties with non-profit-maximizing objectives. In particular, we examine the relationship in China’s listed firms and offer evidence that managerial discretion is related positively to firm performance. Our results suggest that managerial discretion is not necessarily detrimental to firm performance, as traditional agency theory suggests. Rather, managerial discretion may have a positive impact on firm performance if managers’ objectives are better aligned with firm performance than those of controlling parties.

Abstract:
This paper develops an expected utility model of a multinational firm facing exchange rate risk exposure to a foreign currency cash flow. Currency derivative markets do not exist between the domestic and foreign currencies. There are, however, currency futures and options markets between the domestic currency and a third currency to which the firm has access. Since a triangular parity condition holds among these three currencies, the available, yet incomplete, currency futures and options markets still provide a useful avenue for the firm to indirectly hedge against its foreign exchange risk exposure. This paper offers analytical insights into the optimal cross-hedging strategies of the firm. In particular, the results show the optimality of using options in conjunction with futures in the case of currency mismatching, even though cash flows appear to be linear.

Abstract:
The traditional theory of urban land markets assumes perfect contestability–the absolute freedom of market entry–that compels developers to bid up the land rent to equal the economic profit from land use. This assumption, however, is untested empirically due to the difficulties in measuring the ex ante economic profit of land acquisition. We overcome these difficulties by applying the event-study methodology to Hong Kong government land auctions. When a developer acquires a site at a price below its fair market value, the rationality of the stock market entails a positive abnormal return of the developer’s stock. Our analysis shows evidence of positive expected abnormal returns, indicating an imperfectly contestable land market. We further show that the expected abnormal return increases with the site value and the government land disposal level but decreases with the property market liquidity.

Abstract:
This paper proposes a new market-based approach to the bankruptcy problem. A hypothetical claims market, where creditors can trade their claims prior to the allocation of the liquidation value, is considered. The introduction of the claims market opens an atypical arbitrage opportunity, which allows creditors to make profits even by buying and selling the same amount of claims at the same price. This anomaly occurs because the claims market enables the creditors to exploit any sensitivity of a bankruptcy rule to a change in the distribution of claims, and is ruled out by requiring that the bankruptcy rule satisfy a no-arbitrage condition. The no-arbitrage condition turns out to be a necessary and sufficient condition for the existence of equilibrium in the claims market. All equilibria are shown to be equivalent to the outcome of the proportional rule. A connection between the market-based approach and the axiomatic approach is developed and simpler characterizations of the proportional rule are derived. A new normative foundation for the proportional rule is also established.

Abstract:
This study compares, with the use of accounting data, the pre- and postlisting financial and operating performance for the complete sample of the H-firms that were incorporated in mainland China and listed in Hong Kong. Theoretically, there are two major opposing influences on the performance change of these newly listed firms: the negative IPO effect and the positive privatization effect. Our major findings are: (1) the IPO effect dominates the privatization effect, so that the H-firms experienced a significant decrease in profitability and operating efficiency after listing, and (2) the performance of a control sample of newly listed private firms declined more than that of the H-firms, probably because the positive privatization effect somewhat offset the negative IPO effect for the H-firms. This paper is the first to document the positive effect of revenue privatization in listed Chinese companies.

Abstract:
Multiple delivery specifications exist on nearly all commodity futures contracts. Sellers are typically allowed to deliver any of several grades of the underlying commodity and at any of several locations. On the delivery day, the futures price as such needs not converge to the spot price of the par-delivery grade at the par-delivery location, thereby imposing an additional delivery risk on hedgers. This paper derives the optimal hedging strategy for a risk-averse hedger in the presence of delivery risk. In particular, it is shown that the hedger optimally uses options on futures for hedging purposes. This paper provides a rationale for the hedging role of options when futures markets allow for multiple delivery specifications.

Abstract:
Stimulated by recent studies on hyperbolic discounting, Barro (1999) examines the neoclassical model of capital accumulation using a continuous-time model and a general time preference function. However, the analysis seems rather complicated. This paper provides a complementary analysis to Barro (1999) by emphasizing the transparent derivation of the hyperbolic Euler equation and its intuition. To achieve these objectives, a discrete-time model and a specific time preference function first appearing in Phelps and Pollak (1968) are used. The analysis suggests that the derivation of the Euler equations in hyperbolic-discounting growth models shows similarity with the standard exponential-discounting case. Moreover, it shows that an interpretation of the hyperbolic Euler equation for the intertemporal consumption model in Harris and Laibson(2001) contains model-specific elements and therefore may not be valid for other dynamic models. This paper also extends some results in Phelps and Pollak (1968) and Long and Plosser (1983) by obtaining closed-form solutions for some hyperbolic-discounting growth models.

Campbell (1994) argues that a clear understanding of the stochastic growth model can best be achieved by working out an approximate analytical solution, and suggests loglinearizing the Euler equation and the intertemporal resource constraint. The paper follows his idea but streamlines the presentation of the loglinear approximate solution for the neoclassical model of capital accumulation. By focusing on the partial elasticity of capital stock with respect to its lag term, this paper is able to confirm analytically some conclusions based on numerical calculations in previous papers, and to clarify why simpler solution arises in several special cases.

Abstract:
There is ample evidence that the agglomeration of economic activities raises productivity. The available evidence, however, suggests that agglomeration economies do not appear to extend to helping raise employment in cities above less dense locales. But in the absence of other effects, standard economic reasoning suggests that more productive workers should also experience higher employment. This paper explains that the outward shift in the production function by improving investment incentives would also induce firms to create more specialized jobs. The specialized jobs are harder to fill and hence employment needs not go up, despite the increase in productivity.

Abstract:

While the traditional human capital model regards differential lifetime net earnings as the key motivation for emigration, in reality migrants often earn substantially less in the receiving country when they leave a country facing possible changes in political and economic systems. In this paper we incorporate the interaction of economic and political factors in the emigration decision. Empirically we allow economic and political confidence to interact in a discrete choice model of migration decision and test it with the data of Hong Kong when she was facing a transition to a new regime of “one country and two systems”. Our results show that the lack of political confidence increases emigration propensity significantly. Lack of economic confidence also increases emigration propensity though by a lesser extent, whereas expected decrease in income abroad deters emigration by only a small magnitude. Our analysis is pertinent to migration from countries facing political uncertainties such as the LDCs, Asian and former Soviet bloc countries.

Abstract:
Does an increase in interest rate defend the value of a currency? A (one-shot) sharp increase does. In this paper, we start with a game-theoretical model in which a monetary authority increases the interest rate and wins a reputation of being strong. The speculators are thus stopped from continuing the attack. The model is a variant of the reputation game that originates from the discussion of market signalling. As with other models of credible policies, the reputation of being strong hinges on the significant costs incurred to the monetary authority. Unlike the existing models of currency defence, we consider some general opportunity costs of foregone investements, and the depletion of foreign reserves is not a necessary ingredient. Speculators infer the unknown type of the monetary authority solely from high interest rates. This signalling mechanism applies well to reserves-abundant economies, where other interest-sensitive fundamentals are more relevant. Finally, we provide evidence to show that the model is consistent with the events in some emerging market amidst the Asian crisis.

Abstract:
Ethnic networks are important for cross-border economic activities. Ethnic Chinese are well known for their active participation in international trade, particularly in Southeast Asia. Our empirical study of Vietnam private firms show that Chinese businesses have played important role in Vietnam’s export growth after economic reform started in the country more than a decade ago. In addition, we find that, private firms with strong ties with state owned enterprises are in a better position in going abroad. This is because the reform in Vietnam has not substantially weakened the dominance of the state sector in the economy. Finally, our analysis identifies some elements that demonstrate higher initial cost for export. This suggests that there is substantial entry cost in export market. The firm’s export behaviors are consistent with the assumption of entry barrier to export.

Abstract:
The hypothesis of the adjustment costs associated with factor adjustments under intra-industry trade are lower than those under inter-industry trade is initially supported by a specific-factor model analysis theoretically. Yet there is no comprehensive empirical evidence to support that. This paper therefore, tested the hypothesis that factor adjustment under intra-industry trade specialisation predominantly occurs within industries rather than between industries using a dynamic factor demand system.

The test was carried out in three steps. First, the optimal solutions of factor demand and output supply were derived for the dynamic adjustment costs model when the function of production is assigned in a quadratic form. Secondly, using data obtained from the OECD’s international sectoral database in the quasi-fixed input demand equations, adjustment coefficients were estimated at the subdivision level of ISIC manufacturing industries. This derivation was employed to Canada, Germany and the United States due to the availability of data. Thirdly, specifying two effects–a trade specialisation effect and a structural change effect–in the empirical model to explain the determinants of labour and capital adjustment coefficients. The results reveal strongly that if an industry has a high degree of intra-industry trade specialisation, the factor adjustments are more intra-industry oriented.

Abstract:
Ethnic Chinese entrepreneurs are known for their active domestic and cross-border business networking practices, particularly in Southeast Asia. This paper empirically investigates the role of ethnic Chinese networks in promoting foreign direct investment (FDI). Using a standard gravity model to analyze bilateral FDI reported by 54 economies, we find that ethnic Chinese networks are important in facilitating cross-border direct investment between countries. The strength of ethnic Chinese networks between country pairs, approximated by the product of the numbers of ethnic Chinese in both countries, is positively correlated with the cumulative amount of their reciprocal FDI. More importantly, this significant relationship is not limited to countries in Southeast Asia, but is applicable to other country pairs included in the study as well, regardless of whether the investment originated from industrial countries or developing economies. Finally, the analysis finds no evidence that ethnic networks are only effective in countries where economic and legal institutions are under-developed. The measure for ethnic Chinese networks is found significant in promoting FDI to countries with a relatively higher bureaucratic quality, and the magnitude of the coefficient is in fact much larger than that found for FDI destined to countries with a lower bureaucratic quality.

Abstract:
Using a firm-level survey, this study examines the effects of foreign direct investment and foreign technology on local Chinese firms. The empirical results suggest that knowledge inflow carried out mainly through direct foreign investment is an important conduit in promoting Chinese firms’ export. Moreover, foreign knowledge is likely to increase local firms’ total employment and production, especially in the short-run. In addition, local non-affiliate firms can benefit through business dealings with those firms directly associated with foreign businesses. The study also explores the possible contributing factors related to foreign technology transfer, such as domestic competition and employees education level.

Abstract:
Significant transformation of economic activities has taken place in Hong Kong in the past two decades. Hong Kong’s manufacturing industry has declined substantially relative to the service industry in terms of the employment and contribution to GDP. Hong Kong has emerged as a center of services, mainly manufacturing-related producer services. While growth of producer services is expected for most advanced economies, Hong Kong’s transformation from an industrialized city to a center of manufacturing-related services has been dramatically sped up by the opening-up of the Mainland Chinese economy in the past two decades. In addition to its relocation of manufacturing to the mainland China, Hong Kong has played an increasingly important role of intermediary for trade between Mainland China and the world market.

Abstract:
In this paper, we estimate the property price gradients in Hong Kong. We distinguish our efforts from previous studies on the estimation of property price gradients by directly measuring the economic distance, i.e. the commuting cost and commuting time, instead of merely the physical distance. Changes in commuting cost exert a statistically significant and fairly pronounced effect on property values. In fact, our estimations suggest that the saving in commuting cost appears to be over-capitalized in property values. The effect of changes in commuting time on property values is either imprecisely estimated or non-monotonic, however. Nevertheless, the value of time implied by the estimates agrees well with the results reported in the transportation economics literature.

Abstract:
This paper shows that monopoly in the capital equipment market results in higher productivity and wages but lower employment relative to the benchmark of competition. The combined effect on workers’ welfare is negative for expected earnings, defined as the product of the probability of employment and the wage earned when employed, is lowered. More interestingly, the declines in employment and expected earnings are greater for low skill workers. Increases in the relative supply of high skill workers intensify the declines. The employment and expected earnings of all workers as well as the employment of low skill workers relative to high skill workers are all decreasing in the relative supply of high skill workers.

Abstract:
A model of delegation and expertise is presented, with self-interested and privately-informed decisionmakers and experts. Conflict of interests exists both between the decisionmakers and the experts, and between experts within a team. A balanced team of experts with extreme and opposite biases is shown to be acceptable to a wide range of decisionmakers with diverse preferences, but the value of expertise from such a team is low. We also find that a decisionmaker wants to appoint experts who are less partisan than himself, in order to facilitate the pooling of information and thereby increase the quality of decisions by the expert team. Selective delegation, either by controlling the decisionmaking process or by conditioning the delegation decision on his own information, is another effective way for the decisionmaker to safeguard own interests while making use of expert information.

Abstract:
This paper models the accession process to the World Trade Organization (WTO) as a two stage game. In the first stage, member countries choose tariff rates to be applied on trade with each other. In the second stage a non-member country applies for membership in the agreement and negotiates with the member countries over the tariff rates to be applied. Based on the rules of the WTO accession process, we model this negotiation using the Nash bargaining solution. The analysis focuses on the question of how the pattern of trade between the acceding country and the member countries affects the distribution of gains from accession between the members and the acceding countries, given the rules of the WTO negotiation process. We consider two n good, n country trade models which highlight features of the WTO tariff negotiations. The first is a model in which each country imports one good from all of the other countries (competing supplier model). This model highlights the role of the MFN principle, since member countries are forced to extend the same tariff treatment to non-members when they join. We show that the non-member will free ride on tariff reductions among the member countries in this case, and that the non-member will gain a larger fraction of the gains from accession if transport costs are sufficiently low. The second model considers a case in which each country exports a single good to the other countries (principal supplier model). We show that in this case tariff reductions by the member countries reduce the welfare of the non-member country, and the member countries gain a larger share of the gains from accession.

Abstract:

The objective of this study is to examine the effect of prevailing market sentiments in real estate markets on the stock market response to the outcomes of real estate auctions in Hong Kong. The reactions of stock market to the winners of the auctions have at least two interesting implications. On one hand, the success in acquiring a real estate implies that the developer has acquired a project with potentially positive net present value and the stock price of the developers should rise. Bids on real estate development projects are often based on the developer’s estimate of potential costs and profits. These estimates, when conditioned on the current market information, may be highly influenced by the prevailing market sentiments. The complexity of estimating the development costs may cause the developers to arrive at different estimates and thereby different bids. The prevailing market sentiments in the real estate markets may also affect the bidding behavior of the bidders. During periods when the real estate prices are soaring, the bidders may bid more aggressively against each other. As a result, the successful bidder may be the victim of the “winner’s curse”. If this is the case, investors in the stock market should view this as a factor that negatively affects the stock price of the developer, thus discounting the stock price of the winning firm. The availability of the auction records and the stock prices in Hong Kong provides us an excellent opportunity to test the auction theory and allows us to examine how the stock market evaluates these two counteracting effects. Moreover, we can investigate how market sentiments in the real estate markets may affect the stock market response to the auction winners.

Abstract:
Hong Kong’s Mandatory Provident Fund is a forced saving scheme for retirement. This paper discusses the institutional features of the system and examines the reasons for forcing workers to save for retirement. Workers have to bear all the investment risks under the system. The MPF benefits are uncertain and may also be insufficient, with the replacement rates for workers older than 50 lower than 20 percent under some realistic scenarios. The lack of annuitization of the retirement benefits and whether the MPF system can coexist with the existing welfare programme for the aged are also explored in the paper.

Abstract:
This paper explores the implications of inter-generational marital transfers on the allocation of resources within a conjugal household. Adopting a Nash bargaining framework with alternative models of the threat points, it is argued that parents have greater incentive to make transfers to a married child because of the efficiency gains from joint consumption and production of family public good, and also because of the increase in bargaining power of the child in the allocation of private consumption. Such transfers also enhance marital stability by increasing the efficiency gains from marriage.

Abstract:
The paper presents price-based (dual) estimates of total factor productivity growth (TFPG) for the East Asian countries. While the dual estimates of TFPG for Korea and Hong Kong are similar to the primal estimates, they exceed the primal estimates by roughly 1 percent a year for Taiwan and by more than 2 percent a year for Singapore. The basic reason for the large discrepancy for Singapore is that despite the high rate of capital accumulation indicated by Singapore’s national accounts, the return to capital has remained constant in Singapore. Furthermore, changes in the risk-premium, financial market controls, taxes on capital, and public investment subsidies do not explain why the rental rate of capital in Singapore has not fallen.

Abstract:
From 1990 to 1997, over 710 thousand Russian Jews emigrated to Israel, increasing Israel’s working-age population by 15 percent. This paper argues that a canonical one-sector neoclassical growth model explains both the short run and the medium run response of Israel’s economy to this shock. Specifically, we show that average effective wages of native Israelis fell and the return to capital increased during the height of the influx in 1990 and 1991. By 1997 however, both average wages and the return to capital had returned to pre-immigration levels due to an investment boom induced by the initial increase in the return to capital. As predicted by an intertemporal model of the current account, the investment boom was largely financed by external borrowing. Furthermore, despite the high educational levels of the Russian immigrants, the Russian influx did not lower the skill-premia of native Israelis. We show that this result is not explained by Rybczynski-type output composition changes but because the Russian immigrants suffered from substantial occupational downgrading in Israel and thus did not change the relative supply of skilled workers in Israel.

For decades the government of Hong Kong had enjoyed huge fiscal surpluses. Only rarely did Hong Kong register a fiscal deficit. The natural question to ask, following this observation, is where did the surging revenues come from, and whether such hugh revenues can be expected to continue indefinitely.

Abstract:
This paper argues and provides statistical evidence that the very serious recession that Hong Kong underwent in 1998 was not the direct result of the Asian Financial Crisis but rather the result of the ecological consequences of misguided housing policy adopted by the Hong Kong SAR Government. By selling public housing cheaply to tenants, the attractiveness of Home Ownership Scheme housing was reduced dramatically. Price declines of HOS housing spread to housing of a more superior quality because the latter depends on HOS owners trading up. Lacking buyers from among HOS owners, the owners of these units could not trade up either. As a result the entire housing market and economy plunged into deep recession.

Abstract:
That workers in cities are more productive is arguably the most celebrated fact in urban economics. The available evidence, however, suggests that agglomeration economies do not appear to extend to helping raise employment in cities above less dense locales. But in the absence of other effects, standard economic reasoning suggests that more productive workers should also experience higher employment. This paper explains that the outward shift in the production function by improving investment incentives would also induce firms to create more specialized jobs. In equilibrium, the productivity gains may not be dissipated in more job creation, but in the creation of more specialized jobs that may only be sustained in a labor market with a longer job queue.

Abstract:
The Employees Retraining Programme, launched by the Hong Kong government in 1992, was promoted as the solution to structural unemployment resulting from rapid transformation of the economy. However, our study of the labour market performance of a group of trainees who received skills training in 1994/5 shows no evidence of any positive effect on the earnings, days of employment, employment rate or unemployment rate of trainees more than three year after the completion of training when compared to a group of job searchers. In particular, full-time training is found to be less effective than part-time training, and training in general skills (language, computer and office skills) is significantly less effective than training in specific occupational skills. This suggests problems in the design and implementation of retraining in Hong Kong. The Programme has yet to fulfill its rather lofty promise.

Abstract:
The extension of basic schooling from six to nine years in 1968 was the largest expansion of education in Taiwan’s modern history. More than 140 new junior high schools were opened in 1968 under this program, increasing the number of junior high schools by 70 percent from 1967 to 1968. We evaluate the effect of this program on education and wages by analyzing cohort differences in educational attainment induced by the timing of the program and by combining these cohort differences with differences across countries in the number of schools built. These estimates suggest that children who were between the ages of 6 and 11 in 1968 received 0.3 to 0.5 additional years of education for every school constructed per 1000 graduates from primary school. We use the exogenous variation in schooling due to this program to construct instrumental variable (IV) estimates of the returns to education. We find that IV estimates based on cohort differences in education are lower than the corresponding OLS estimates, but IV estimates based on regional differences in inter-cohort patterns are typically higher than the OLS estimates.

Abstract:
This paper places the competitive firm a la Sandmo in a standard efficiency wage model, wherein the work effort of labor depends on the wage rate set by the firm. Irrespective of the availability of hedging opportunities, we show that the Solow condition under which the equilibrium effort-wage elasticity equals unity is a norm. Thus, the optimal wage rate paid by the firm is invariant to the risk attitude of the firm and to the incidence of output price uncertainty. We further show that hedging activities induce the firm to hire more labor as a result of the reduction in its risk exposure. Thus, the introduction of futures markets is beneficial in that employment is increased and output is enhanced.

Abstract:
This paper combines unemployment and vacancy data to analyze the efficiency of the Hong Kong labor market for the period 1976 to 1977. We confirm that the negative relationship between unemployment and vacancy, commonly known as the Beveridge curve, applies to the Hong Kong labor market. There was an inward shift of the Beveridge curve around 1982, which implies falling match fractions since then. We also find systematic evidence that Hong Kong has been close to full employment for on average, around eighty percent of unemployment in the period was due to structural and frictional unemployment with only twenty percent attributable to cyclical unemployment.

The present study investigates whether Hong Kong’s volatile real estate market is consistent with a non-linear consumption-based asset pricing model. It finds that the asset-pricing model is not rejected for some types of properties. However, the differentials between the returns to residential properties and risk free rate are too large to be explained by the model.

Abstract:
The market for resident domestic helpers offers a rare opportunity where the surplus from employment relationship can be quantitatively measured for each individual employee. Using the difference between employer’s cost of time and employee’s wage as a measure of rent, it is found that wages for domestic helpers are positively related to rent. However the apparent sharing of rent is better explained by matching than by efficiency wage models. Rent sharing is observed even in households where monitoring or turnover costs are low. Rent sharing is not observed among newly arrived foreign domestic helpers, whose ability remains to be revealed.

The recently developed approximate band-pass filter is used to extract the fluctuations at business cycle frequencies (8 to 32 quarters) of macroeconomic time series. Based on the filtered time series, we identify the cyclical turning points, describe the pattern of output fluctuations, and examine the co-movement of various macroeconomic variables.

Abstract:
This paper analyzes gender wage differentials and the role of occupational segregation in Hong Kong. It is found that the female-male earnings ratio has increased substantially from 0.710 in 1981 to 0.839 in 1996. The Brown et al. decomposition, which takes into account occupational differences, shows that the gender pay gap is mostly within occupations and most of the intra-occupation wage gap is unexplained. The gender pay differential due to occupational differences is small; in fact, the overall occupational segregation favours females in Hong Kong.

Abstract:
This paper offers a theoretical and empirical analysis on the sources of the narrowing gender gap in wages, based on two census data sets in Hong Kong. Extending a recent important contribution by Galor and Weil (1996), the model implies that when an economy transforms from a manufacturing-oriented economy to service-oriented economy, a woman’s productivity relative to a man’s will generally increase. The model, together with the Galor-Weil model, predicts that the gender gap is smaller in the occupations in which physical labor is less intensively used. The implication of the theoretical analysis is then tested based on one percent random sub-samples of 1981 and 1991 population censuses. The empirical results are strongly supportive of the predictions of our model.

Abstract:
In a recent paper (Chan 1996), I suggest that a contest between internal and external candidates for a position within a firm is generally biased in favor of the former in order to maintain work incentives. This implies that a successful external candidate tends to be superior in ability to his internally promoted colleagues and therefore enjoys a higher probability of subsequent promotion. Moreover, this effect tends to diminish as one goes up the hierarchy. Analyzing nine years of personnel data from a U.S. financial corporation, I find consistent support for this hypothesis.

The Employees Retraining Programme , launched by the Hong Kong government in 1993, was promoted as the solution to structural unemployment resulting from rapid structural transformation of the economy. However, our study of the labour market performance of a group of trainees who received training in 1994/5 shows no evidence of any positive effect on the earnings or employment rate of trainees one year after the completion of training when compared to various comparison groups. This apparent lack of success can be traced to low target efficiency and distorted incentives that result in over-utilization of retraining resources.
