This paper examines the impact of trade liberalization on firms' product and labor market power. We estimate the prevalence and intensity of price-cost markups and either wage markups or wage markdowns, taking the dependence between these model-consistent measures of product and labor market power into account. Exploiting reductions in tariffs upon China's WTO accession, we find that trade liberalization has not switched firms away from exercising product and labor market power. Reducing input tariffs has increased firms' price-cost markups but decreased their wage-setting power. We reveal hetero-geneous trade liberalization effects on the intensity of firms' product and labor market power.
This paper examines the impact of WTO membership on the extensive and intensive margins of product and labor market power of Chinese manufacturing firms during the period 1999- 2006. We first identify a firm's regime of competitiveness, corresponding to a combination of a product market setting and a labor market setting, at any point in time through implementing the testing procedure of Kodde and Palm (1986), the distance test. Our descriptive differencesin-differences analysis shows that an industry's dominant regime of competitiveness is stable over time. Exploiting variation in input and output tariff reductions after WTO accession across industries, we then show that on the extensive margin, reducing tariffs on intermediate inputs decreases the likelihood of shifting firms away from an imperfectly competitive labor market setting where the marginal employee is paid a real wage either above or below her marginal product (i.e. wage markup or markdown). In contrast, falling tariffs on final goods increases the likelihood of switching firms away from setting wage markdowns. On the intensive margin, trade liberalization via input tariff reductions is found to increase a firm's price-cost markup but to decrease the degree of wage-setting power that a firm possesses. Such joint responses of firms' pricing behavior to trade policy changes are important for understanding increased inter-firm wage disparities.
Looks at the recent empirical literature on the effects of trade reforms on firm level wages, employment and labor demand elasticities in import-competing sectors.
We study the effect of heterogeneous monopsony power across Chinese firms on the equilibrium allocation of labor. Based on the fact that heterogeneity in monopsony power results from the heterogeneity in workers' preferences for the jobs provided by an individual firm, we build a model to derive that the variance in logarithmic markdown serves as sufficient statistics that can be used to infer the impact of heterogeneous monopsony power on overall production efficiency at the national level. We further quantify the welfare effect associated with labor reallocation after China joined the WTO in 2001. The empirical results suggest that lower input tariffs decrease the level of misallocation in the labor market, which is captured by the decreased variance in logarithmic markdown. In contrast, reductions in output tariffs have no significant effect. Overall, the improved allocation of labor accounts for 5% of the total production efficiency gains from China's trade liberalization.
This compelling two-volume collection presents the major literary contributions to the economic analysis of the consequences of trade liberalization on growth, productivity, labor market outcomes and economic inequality. Examining the classical theories that stress gains from trade stemming from comparative advantage, the selection also comprises more recent theories of imperfect competition, where any potential gains from trade can stem from competitive effects or the international transmission of knowledge. Empirical contributions provide evidence regarding the explanatory power of these various theories, including work on the effects of trade openness on economic growth, wages, and income inequality, as well as evidence on the effects of trade on firm productivity, entry and exit. Prefaced by an original introduction from the editor, the collection will to be an invaluable research resource for academics, practitioners and those drawn to this fascinating topic.

This dissertation studies trade liberalization and labor market outcomes. The first two chapters examine the impact of China's trade liberalization on the adjustment of U.S. labor market for skilled and unskilled workers in a dynamic general equilibrium framework with firm heterogeneity and factor proportions. In the first chapter, I most specifically look into the effect of trade cost reduction on U.S. skill premium in an environment which I abstract from labor market friction. Featuring labor market search and matching frictions, the second chapter is part of a broader agenda on the labor market effect of China's trade liberalization and U.S. firms' offshoring decisions, with a greater focus on the dynamics of unemployment of skilled and unskilled workers. The third chapter investigates the impact of the China's increased trade openness on its local labor market. It examines the effects of China's domestic migration policy change and trade liberalization on wage inequality in China using a dynamic general equilibrium model of international trade and internal migration across regions. This dissertation showcases some of the ways trade policy can interact with firms' endogenous offshoring and entry decisions, workers' mobility choices, and labor markets frictions in a dynamic fashion. More specifically, the first chapter studies how wage inequality between skilled and unskilled workers interact with multinational firms' decisions and countries' different factor endowments using a two-country dynamic stochastic model featuring task-offshoring, heterogeneous firms and factor proportions. It shows that besides the traditional Stolper-Samuelson mechanism that shifts factors of production towards a country's comparative advantage sectors, there also exist other firm-level adjustment mechanisms that widen the wage gap after trade liberalization. It finds that in the short run, offshoring widens wage inequality between skilled and unskilled workers through increasing high-skilled wage and lowering low-skilled wage. Such effect is more announced in the beginning phase of the adjustment, and slows down over time as low-skilled wage rises faster than the cool-down of high-skilled wage increase. The intensive margin and the extensive margin are both active in shaping rising wage gap in the home country, with the latter playing a more important role in the short to medium run compared to the beginning stage following the shock. The second chapter studies the dynamic effects of offshoring on the unemployment rates and wage inequality across the high-skilled and low-skilled workers through the dynamics of firms' production location and entry decisions in general equilibrium. First, I examine the dynamic effects of offshoring cost reduction due to China's trade liberalization. Estimates from vector autoregressions (VARs) show that a decrease in offshoring costs is associated with a short-lived increase in low-skilled unemployment, but a persistent decline in high-skilled unemployment and a less persistent expansion of wage gap in the source country. Second, I build a two-country trade-in-task model with firm heterogeneity, endogenous selection into entry and offshoring as well as search and matching frictions to study the channels through which offshoring cost reductions affect the labor market outcomes for different skill groups over time. The model successfully reproduces the VAR evidence and highlights the importance of endogenous firm entry and labor market frictions in generating the empirical dynamic responses of wage and unemployment across different skill groups. The third chapter investigates China's labor market's responses to its own trade liberalization, which is a relatively less explored topic compared to the relationship between the China shock and labor market changes in other countries. Using data from CHIP (Chinese Household Income Project), this chapter aims to fill this gap by estimating the effects of trade liberalization on Chinese local labor markets. In addition, it investigates changes in urban to rural wage inequality and skill premium in urban and rural areas separately with the availability of surveys conducted in urban and rural households. In the model, a dynamic general equilibrium framework with heterogeneous firms, heterogeneous workers and internal migration is employed to study the impact of policy-generated trade cost reduction and easing of migration restrictions on Chinese wage inequality. I focus on the role of labor mobility that characterizes the large rural-to-urban migration in the midst of trade liberalization in shaping skill premium and urban to rural wage inequality. Calibrating the changes in policy-generated migration cost reduction and trade cost decline, as well as productivity increase in the tradable sector, this paper analyzes the responses of different measures of wage inequality and other macroeconomics variables following these shocks. This dissertation highlights the role of interaction of firm dynamics, factor endowments and labor market frictions in shaping the labor market adjustments. The positive effects of offshoring on the labor market for workers regardless of skill levels suggest that more trade frictions designed to restrict offshoring is likely to hinder firm entry, which is a key driver that contributes to higher wages and lower unemployment rates of both skilled and unskilled workers over time. It also points to the importance of labor market reforms by showing that easing of migration restriction and search and matching frictions are both beneficial to exports and wages of all workers, with consequences of rising wage inequality though.
This paper examines the effect of trade reform on wages and unemployment in a two-sector, three-good economy in which labor is imperfectly mobile across sectors. Wages in the export sector are set so as to minimize turnover costs. The analysis shows that a reduction in tariffs, coupled with an adjustment in lump-sum taxes to equilibrate the government budget, lowers wages in all production sectors in the short and the medium run but has an ambiguous effect on unemployment. Although employment and production of exportables expand in the medium run, the unemployment rate may rise or fall depending on whether the elasticity of wages in the export sector with respect to wages in the nontraded goods sector is lower or greater than unity. Potentially adverse effects may be mitigated in the long run, however, as a result of induced shifts in the structure of production activities.
This report quantifies labor mobility costs in developing countries and simulates the implied adjustment paths of employment and wages following a change in trade policy. High mobility costs are shown to reduce the potential gains to trade reform.
