Labor Mobility, Trade, and Social Capital

Labor market integration raises welfare in the absence of distortions. This paper examines labor and goods market integration in a general‐equilibrium model with social capital. The findings are: (i) labor market integration has an ambiguous impact on welfare, and raises it if the goods and labor skills are sufficiently different; (ii) compared to Pareto optimum, labor mobility (social capital) is excessively large (depleted); (iii) trade is superior to labor market integration if trading costs are no higher than private migration costs, otherwise the outcome is ambiguous; and (iv) the creation of new institutions in response to labor market integration has an ambiguous impact on welfare.     

Job mobility of residents and migrants in urban China

The large-scale reform of the state-owned sector and the development of a private sector in the 1990s changed the nature of employment in urban China. The system of allocated, lifelong jobs, denoted the iron rice bowl, that had previously prevailed under state planning was eroded, permitting more labor turnover and mobility. Using an urban household survey for 1999 that has rich data on job duration and job change, we analyze inter-firm mobility in the urban labor market, its evolution, and its explanation. A distinction is made between the institutionally favored urban residents and the rural–urban migrants. The mobility rate of migrants greatly exceeds that of urban residents. The extent, patterns, determinants, and consequences of mobility for the two groups are explored and compared. Journal of Comparative Economics 32 (4) (2004) 637–660.     

Rigid labour markets with trade and capital mobility: theory and evidence

Abstract We develop a multi‐country model with imperfect labour markets to study the effect of labour market frictions on bilateral trade flows. We use a framework that allows for goods trade and capital mobility and show that labour market imperfections exert opposite effects in the absence of capital mobility (the short run) and its presence (the long run), respectively. In the short run, a higher degree of labour market rigidity decreases the value of total trade, but increases the share of intra‐industry trade for a country that is larger than its trading partner. The reverse effects are observed when capital is allowed to cross country borders. Using data on unemployment and income distribution for 23 OECD countries, we compute the central parameter in our theoretical model that describes the degree of labour market rigidity. We use this new empirical concept to provide evidence for our theoretical findings by means of reduced‐form regressions as well as simulation results of a calibrated general equilibrium model.     

The trade paradox persists under excise taxes

Brander and Krugman (1983) and Sertel (1988) followed by Krugman (1989), showed two sides of a ‘trade paradox’: The paradox in competition, viz. that opening trade (or increasing competition) may cause welfare to decline, and the paradox in efficiency, viz. that an increase in unit transport cost may increase welfare. In this paper, we consider the situation in an environment where interventionist trade policies are not permitted but each country is sovereign to impose an excise tax (or subsidy). The paradoxes persist under equilibrium excise taxes, reckoned both at the non-cooperative (Nash or dominant strategy) equilibrium and at the cooperative solution among tax-imposing authorities maximizing welfare. We also see that the paradoxes persist in a taxless environment where market equilibrium is Stackelberg rather than Cournot.     

Capital specificity,imperfect labor mobility and growth in developing economies

Labor markets in developing economies may be afflicted by a multiplicity of interacting distortions. We consider a general equilibrium model of an economy distorted by both sector-specific sticky wages and imperfect mobility of labor. In this framework, we contrast the implications of capital accumulation in the short and long run. We show that, in contrast to both the case in the absence of a sector-specific sticky wage and the case in the absence of imperfect labor mobility, the short and long-run effects of growth on the economic system converge as the degree of labor mobility is limited.     

Labor supply in urban China

Using labor supply responses from 10,560 urban Chinese workers, two-stage least squares estimations identify positive compensated wage effects and negative income effects that are, for the most part, statistically significant. The gross wage effects are mostly positive but they indicate relatively low uncompensated labor supply elasticities. The compensated wage effects are much larger; these may be important in assessing the labor market consequences of reform policies that monetize non-pecuniary benefits. The significance of labor supply responses depends on individual responsibilities within the family; the effects are largest for women and non-household heads.

Trade,Job Losses and Gender: A Policy Perspective

This paper presents a gender perspective of the Trade Adjustment Assistance (TAA) program. The TAA is the primary US policy to assist the transition of workers displaced due to trade related economic restructuring. In comparison to the relatively substantial research on gendering trade policies in developing economies there is very limited focus on gendering policy responses to trade in the US. We argue that there is a specific gender trend in the trade-displacement patterns in the US which calls for a gender sensitive policy response. We examine the TAA in light of this trend and offer some suggestions for a gendered approach to providing assistance to workers negotiating an increasingly flexible global labor market.

Labor Market Institutions and the Second-Best Tariff

Labor market distortions provide a second-best case for protection. However, the implications are less obvious when the product market is imperfectly competitive too, as suggested by several partial equilibrium studies. This paper adopts a general equilibrium approach, combining unionization in labor markets with monopolistic competition in product markets. Two labor market settings are considered: fully centralized wage bargaining ("Scandinavia", for short) and negotiation at the firm level ("Latin America"). The competitive labor market case is used as a benchmark. It is shown that in Latin America the second-best tariff is higher, and the welfare level lower, than in the benchmark case. Scandinavia reaches the first best under free trade.     

The corporate income tax in an open economy

The paper begins with a brief review of the distortion literature, stressing its relation to the general equilibrium consequences of the corporate income tax. The consequences for international trade of the distortions associated with the tax are then examined, and among other things it is found that trade could reduce welfare. Finally, the implications of trade for the incidence question are examined, and it is shown that whether labor or capital bears the burden of the tax depends entirely on whether the tax is imposed in the labor-intensive or the capital-intensive industry.     

市场竞争不完全与企业内部工资差距*——基于产品与劳动力市场融合视角的分析

理解工资差距的形成机制是在新时期破解发展不平衡不充分问题，进而实现共享发展的关键。本文从产品与劳动力市场竞争不完全相融合的视角，扩展了中国企业内部技能员工与非技能员工工资差距形成机制的研究，兼论消除竞争不完全的效率提高。基于中国企业数据并在统一的框架下构建市场竞争不完全的测算指标，本文发现：中国的市场化改革并不必然带来收入差距的扩大，不完全的市场化改革形成的产品与劳动力市场竞争不完全才是引发企业内部收入差距的重要原因。当存在市场竞争不完全时，企业会将产品市场势力扩展到劳动力市场，形成劳动力市场竞争不完全对工资差距的更大影响。这意味着单一的市场化改革不能有效缓解收入差距，只有产品与劳动力市场的同步改革才能达到最优的政策效果。中国的市场化改革可以在初次分配中通过发挥市场机制兼顾效率与公平。     

Labor Markets and Kaleidoscopic Comparative Advantage

Capturing the notion of kaleidoscopic comparative advantage ( Bhagwati, 1998 ), we show that international trade increases the volatility of profitability. In this framework, we address the labor market implications of an increase in openness, when insurance and credit markets are imperfect. With kaleidoscopic comparative advantage, trade raises the likelihood of firm shutdown and worker displacement, which, in equilibrium, affects wage contracts. In a simple model, we analyze the consequences for wage levels, earnings volatility, job instability, and income distribution, of the openness of previously nontraded industries to international trade.     

Fertility Decisions and Gender Differences in Labor Turnover, Employment, and Wages

A striking observation of the U.S. and other labor markets is the weak position of women in terms of job attachment, employment, and earnings relative to men. We develop a model of fertility and labor market decisions to study the impact of fertility on gender differences in labor turnover, employment, and wages. In our framework, individuals search for jobs and accumulate general (experience) and specific (tenure) human capital when they work. They can also increase their wage by moving to a job of higher quality. Labor market decisions (e.g., job acceptance and job mobility) may differ across genders: females that give birth may decide to interrupt their labor market attachment in order to enjoy the value of staying at home with their children. The model economy is successfully calibrated to match aggregate statistics in terms of fertility, employment, and wages. We find that fertility decisions generate important gender differences in turnover rates, with long lasting effects in employment and wages. These differences in labor turnover account for almost all the U.S. gender wage gap that is attributed to labor market experience by Blau and Kahn (2000, Journal of Labor Economics15(1), 1–42). The model also implies a very small role of tenure capital in accounting for wage differences between males and females (gender gap), and between females with and without children (family gap).

Transition Problems in Policy Reform: Agricultural Trade Liberalization in India

What will be the domestic growth and distributional effects of agricultural trade liberalization in India? How fast should Indian agriculture be liberalized and what policies should characterize the transition? This paper uses Indian agriculture to analyze medium‐term transition problems that arise in many major economic reforms. Employing a dynamic applied general‐equilibrium model, the paper focuses on the implications for policy design of the absence of efficient capital and labor markets and on the distributional consequences of economic reform in the presence of realistic limits on available intervention instruments. The key finding is that trade adjustment should be supplemented by policies that raise land productivity and, because this takes time, the adjustment should be gradual.     

Small firms in Portugal: a selective survey of stylized facts,economic analysis,and policy implications

I survey a number of stylized facts pertaining to the dynamics of firm entry, growth, and exit in competitive industries. I focus particularly on data for Portugal, although I also consider, for comparison purposes, data from other countries. I then present a series of theoretical models that attempt to explain the stylized facts and evaluate the welfare impact of market distortions. Finally, I derive a number of policy implications, all centered around the notion of economic mobility.

Trade, Skills and Adjustment Costs: A Study of Intra-Sectoral Labor Mobility

The relationship between the ability of workers to change job, sector or industry and the short‐run adjustment costs associated with a reallocation of labor is the subject of lively debate among academics. This paper examines recent sector and industry level labor market adjustment in the UK using data from the Quarterly Labour Force Survey. We explore the link between the nature of UK trade patterns and labor adjustment within the manufacturing sector and employ a multinomial logit approach to examine the determinants of “within” and “between” industry mobility. By controlling for individual skill specificity we find some evidence of a link between intra‐industry trade and intra‐industry labor adjustment.     

The sequencing of reform in transition economies

In this paper, we examine the consequences of sequencing on the progress of reforms in transition economies. The paper uses panel logit models to determine whether or not progress in some reforms enhances the prospects for other reforms. We find that progress on small-scale privatization is associated with advances in several other reforms, perhaps because small-scale privatization creates lobbies for reform. Our estimations suggest that a comprehensive program of small-scale privatization is needed to stimulate large-scale privatization, trade, and banking reform in a country that has undertaken little reform. Moreover, if restructuring is to occur banking reform is necessary. We also find that relaxing the fiscal constraint stimulates large-scale privatization, restructuring, and trade reform. Finally, we find that negotiations about EU accession negotiations advance the transition but only in banking reform and competition policy.

Endogenous trade policy in general equilibrium: An interaction of redistribution rule,trade openness,and labor market condition

Using a general equilibrium framework, the paper derives trade policy endogenously for a small country. It shows that, contrary to the existing literature, a lobbying industry is not guaranteed trade protection; it may even face trade taxes. Besides lobbying, trade policy depends on other factors such as the trade revenue distribution rule, income distribution across groups, trade openness, factor substitutability in production, industry employment size, and labor market flexibility. The paper also shows that the observed phenomenon of government preference for import tariffs over export subsidies—a long overdue puzzle—is an inherent outcome of lobbying equilibrium. It also shows that trade policies such as import tariffs and export taxes that have the same impact on economic market—Lerner symmetry (1936)—are driven by the same forces in the political market.     

The Effects of Market Liberalization on the Relative Earnings of Chinese Women

In this paper, we explore the effects of differences in labor market institutions and the degree of market liberalization on the size and composition of gender wages gaps in China's urban labor markets. We use enterprise-ownership type, enterprise age, and workers' methods of finding employment as proxies for the extent of market liberalization. We find both the size of the wage gaps and the proportion of the gap left unexplained by differences in observed characteristics largest in the most liberalized joint-venture sector and smallest in the least liberalized state sector. We next investigate the effects of differences in the wage structure on the gender wage gaps. We find that differences in the wage structure, in general, and the degree of wage dispersion, in particular, are extremely important in accounting for the larger wage gaps in the joint-venture and collective sectors relative to the state-owned sector.

Optimal Taxation of Risky Human Capital*

In a two‐period life‐cycle model with ex ante homogeneous households, earnings risk, and a general earnings function, we derive the optimal linear labor tax rate and optimal linear education subsidies. The optimal income tax trades off social insurance against incentives to work. Education subsidies are not used for social insurance, but they are only targeted at offsetting the distortions of the labor tax and internalizing a fiscal externality. Both optimal education subsidies and tax rates increase if labor and education are more complementary, because education subsidies indirectly lower labor tax distortions by stimulating labor supply. Optimal education subsidies (taxes) also correct non‐tax distortions arising from missing insurance markets. Education subsidies internalize a positive (negative) fiscal externality if there is underinvestment (overinvestment) in education because of risk. Education policy unambiguously allows for more social insurance if education is a risky activity. However, if education hedges against labor‐market risk, optimal tax rates could be lower than in the case without education subsidies.
