Trade reform and firm-level labor demand in Cameroon

This paper investigates the impact of trade (tariffs and import penetration) and foreign direct investment (FDI) on labor adjustment and labor-demand elasticities in Cameroonian manufacturing sector. Unlike previous studies, I distinguish the effect on different skill groups of employees. Using firm-level data pooled across sectors, I find that trade openness leads to faster adjustment of different labor inputs with a higher speed for unskilled workers. Tariff liberalization does not have any statistically significant effects on labor-demand elasticities. I find strong evidence for the impact of imports on skilled-labor-demand elasticity when I replace tariffs with import-penetration ratios. I also find strong evidence that FDI inflows strongly increase unskilled-labor-demand elasticity. The sector-level results do not alter the previous findings.     

Trade liberalization and the allocation of labor between households and markets in a poor country

We consider the relationship between relative price changes and the allocation of labor between households and the formal wage labor market in the context of Vietnam's liberalization of its rice trade in the 1990s. Many individuals in poor economies work within their own household rather than in formal labor markets. We find that larger rice price increases in a community are associated with declines in hours adults devote to work within the household and increases in time spent in the wage labor market. We also observe increased specialization in household economic activities accompanying these shifts in hours towards wage work. Our results are consistent with the idea that a growth in the extent of the market shifts production and labor from households to markets during development, thereby inducing gains from specialization. Thus, the reallocation of labor between households and markets in response to a trade liberalization might be an important component in understanding the link between trade and growth in very poor economies, currently the focus of the Doha WTO negotiation round.     

Welfare implications of trade liberalization and fiscal reform: A quantitative experiment

This paper studies the welfare implications of revenue-neutral trade liberalization and fiscal reform programs for developing economies using a multi-sector dynamic general equilibrium model of a small open economy. We analyze how different combinations of tariffs – on imported consumption goods, intermediate inputs, and capital goods – and taxes – on consumption, labor income and capital income – affect the transitional and long-run welfare. We report three main findings. First, trade liberalization programs financed by consumption and labor income taxes tend to result in substantial welfare gains, but financing the lost tariff revenue through capital income taxes can have an adverse impact on welfare. Second, a significant fraction of welfare changes is due to transitional effects stemming from the allocation of resources in response to changes in tariffs and taxes. Third, trade liberalization and fiscal reform programs often translate into much larger welfare gains in countries that are more open to international financial markets.     

Trade liberalization and the evolution of skill earnings differentials in Brazil

Skilled labor earnings differentials decreased during the trade liberalization implemented in Brazil from 1988 to 1995. This paper investigates the role of trade liberalization in explaining these relative earnings movements. We perform several independent empirical exercises that check the traditional trade transmission mechanism, using disaggregated data on tariffs, prices, earnings, employment and skill intensity. We find that: i) employment shifted from skilled to unskilled intensive sectors, and each sector increased its relative share of skilled labor; ii) relative prices fell in skill-intensive sectors; iii) tariff changes across sectors were not related to skill intensities, but the pass-through from tariffs to prices was larger in skill-intensive sectors; iv) the decline in skilled earnings differentials mandated by the price variation predicted by trade was even larger than the observed one. The results are compatible with trade liberalization accounting for the observed relative earnings changes in Brazil. They also highlight the importance of considering the effects of differentiated pass-through from tariffs to prices.     

Migration and trade: Theory with an application to the Eastern-Western European integration

The remarkable increase in trade flows and in migratory flows of highly educated people are two important features of globalization of the last decades. This paper extends a two-country model of inter- and intra-industry trade to a rich environment featuring technological differences, skill differences and the possibility of international labor mobility. The model is used to explain the patterns of trade and migration as countries remove barriers to trade and to labor mobility. We parameterize the model to match the features of the Western and Eastern European members of the EU and analyze first the effects of the trade liberalization which occurred between 1989 and 2004, and then the gains and losses from migration which are expected to occur if legal barriers to labor mobility are substantially reduced. The lower barriers to migration would result in significant migration of skilled workers from Eastern European countries. Interestingly, this would not only benefit the migrants and most Western European workers but, via trade, it would also benefit the workers remaining in Eastern Europe.     

The impacts of trade liberalization on informal labor markets: A theoretical and empirical evaluation of the Brazilian case

Following trade liberalization, several developing countries experienced a sharp increase in the share of informal manufacturing employment. In this paper, I examine the impacts of trade liberalization on the labor markets of a small open economy, in an environment in which tariffs affect firms' payroll tax compliance decisions. I demonstrate that a reduction in domestic import tariffs reduces the average formal wage and show that the direction of the effect on the share of informal employment depends on the initial labor market conditions. A cut in trading partner import tariffs decreases the share of domestic informal employment and increases the average formal wage. I confirm the model's principal findings empirically, using data from the 1989–2001 Brazilian trade liberalization episode. I find the results robust to endogeneity and self-selection concerns, which are addressed, respectively, using instrumental variable and switching regression approaches.     

The effect of trade liberalization on child labor

The question of how trade liberalization affects the employment of children in developing economies is at the core of the debate on globalization. Trade theory predicts that an increase in the price of an exported good could either increase or decrease child labor depending on the magnitudes of the substitution and income effects. In this paper, we study the relationship between changes in the relative price of an exported commodity and child labor using household-level data from within a poor country. In particular, we relate child labor to regional and intertemporal variation in the real price of rice surrounding national and international rice market integration in Vietnam. We find that higher rice prices are associated with declines in child labor. Income effects play an important role in this relationship. Rice price increases are associated with the largest declines in child labor in households that are large net producers of rice. These findings show that greater market integration can be associated with less child labor. Moreover, our results suggest that the use of punitive trade sanctions on exports from developing countries to eradicate child labor is unlikely to yield the desired outcome.     

中美贸易结构性失衡:基于赫克歇尔—俄林模型的分析

把中美贸易失衡问题置于国际分工的新格局下进行分析,不难发现,中美贸易逆差的根本原因在于世界头号服务业强国与世界头号制造业大国之间在服务贸易和商品贸易上发生的结构性失衡。中美贸易失衡与全球服务贸易和商品贸易在自由化进程上的非对称性紧密联系在一起。考虑到全球服务贸易自由化的缓慢进展,以及中国对服务贸易自由化已经做出的承诺水平,中美贸易的结构性失衡在相当长的时期内将难以消除。     

Globalization, regional wage differentials and the Stolper-Samuelson Theorem: Evidence from Mexico

In this paper, I study what factors determined the changes in Mexico's regional wage differentials during the nineties. I exploit the regional variation in exposure to international markets to identify the effects of NAFTA on wages and the skill premium. The results support the presence of Stolper-Samuelson type of responses during Mexico's trade liberalization: regions more exposed to globalization appear to have exhibited an increase in overall wage levels, but a decrease in the skill premium, relative to other regions of the country. The results suggest that trade liberalization has a spatial dimension that is usually neglected in traditional models.

Trade, wages, and the political economy of trade protection: evidence from the Colombian trade reforms

Worker industry affiliation plays a crucial role in how trade policy affects wages in many trade models. Yet, most research has focused on how trade policy affects wages by altering the economy-wide returns to a specific worker characteristic (i.e., skill or education) rather than through worker industry affiliation. This paper exploits drastic trade liberalizations in Colombia in the 1980s and 1990s to investigate the relationship between protection and industry wage premiums. We relate wage premiums to trade policy in an empirical framework that accounts for the political economy of trade protection. Accounting for time-invariant political economy factors is critical. When we do not control for unobserved time-invariant industry characteristics, we find that workers in protected sectors earn less than workers with similar observable characteristics in unprotected sectors. Allowing for industry fixed effects reverses the result: trade protection increases relative wages. This positive relationship persists when we instrument for tariff changes. Our results are in line with short- and medium-run models of trade where labor is immobile across sectors or, alternatively, with the existence of industry rents that are reduced by trade liberalization. In the context of the current debate on the rising income inequality in developing countries, our findings point to a source of disparity beyond the well-documented rise in the economy-wide skill premium: because tariff reductions were proportionately larger in sectors employing a high fraction of less-skilled workers, the decrease in the wage premiums in these sectors affected such workers disproportionately.     

Innovation and trade with heterogeneous firms

This paper examines how trade liberalization affects the innovation incentives of firms, and what this implies for industry productivity. For this purpose we develop a reciprocal dumping model of international trade with heterogeneous firms and endogenous R&D. Among the robust results that hold both in the short run when there is no entry, and in the long run under free entry are that trade liberalization increases aggregate R&D when trade costs are low and decreases R&D when trade costs are high. Expected industry productivity rises as trade costs fall.     

The effects of offshoring on the elasticity of labor demand

In this paper, I use detailed plant-level data to analyze the relationship between offshoring and labor demand elasticities in the U.S. manufacturing sector during the 1972-2001 period. The results suggest that conditional demand elasticities for production workers are positively associated with increased exposure to offshoring both in the short-run and in the long-run. This relationship holds both for the unbalanced panel of plants and, for plants which continue their operations throughout the sample period. Controlling for skill biased technical change does not alter the magnitude or the significance of the estimated positive relationship between offshoring and labor demand elasticities.     

Trade liberalization and intersectoral labor movements

This paper examines the impact of trade liberalization episodes on movements of labor across sectors. The aim is to assess empirically whether increased trade openness leads to increased structural change and, if so, to what extent. Results for a set of 25 liberalization episodes suggest weakly negative effects of liberalization on the extent of intersectoral labor shifts at the economy-wide 1-digit level of disaggregation. We do uncover increased sectoral change after liberalization at the 3-digit level within manufacturing, although the estimated effects are statistically weak and small in magnitude. The effects of liberalization on labor shifts differ across individual countries, in a way related to the scope and depth of reforms.     

Trade and industrial location with heterogeneous labor

It is shown in the context of a new economic geography model that when labor is heterogeneous trade liberalization may lead to industrial agglomeration and inter-regional trade. Labor heterogeneity gives local monopsony power to firms but also introduces variations in the quality of the job match. Matches are likely to be better when there are more firms and workers in the local market, giving rise to an agglomeration force which can offset the forces against, trade costs and the erosion of monopsony power. A robust agglomeration equilibrium is derived analytically and its properties illustrated with numerical simulations.     

Buyer power in international markets

This paper investigates the implications for international markets of the existence of retailers/wholesalers with market power. Two main results are shown. First, in the presence of buyer power trade liberalization may lead to retail market concentration. Due to this concentration retail prices may be higher and welfare may be lower in free trade than in autarky, thus reversing the standard effects of trade liberalization. Second, the pro-competitive effects of trade liberalization are weaker under buyer power than under seller power.     

Bilateralism, multilateralism, and the quest for global free trade

We develop an equilibrium theory of trade agreements in which both the degree and the nature (bilateral or multilateral) of trade liberalization are endogenously determined. To determine whether and how bilateralism matters, we also analyze a scenario where countries pursue trade liberalization on only a multilateral basis. We find that when countries have asymmetric endowments or when governments value producer interests more than tariff revenue and consumer surplus, there exist circumstances where global free trade is a stable equilibrium only if countries are free to pursue bilateral trade agreements. By contrast, under symmetry, both bilateralism and multilateralism yield global free trade.     

Unexpected Effects of the Washington Consensus: Trade Liberalization and Migration Flows in Latin America

The traditional theory of international trade assumes that there is a substitution relationship between international trade and migration flows. However, trade liberalization in Latin America has come with an increase in emigration. This article, based on an econometric analysis for the period 1981–2002, shows that there is a complementary relationship between trade and international migration. One explanation is related to the Washington Consensus. In particular, higher labor market flexibility, in the context of trade openness, has resulted in higher levels of unemployment. Therefore, emigration represents a safety valve that reduces the pressure on Latin American labor markets.     

The unfinished agenda: Indian agriculture under the structural reforms

Employing a dynamic nine-sector, seven-income classes computable general equilibrium (CGE) model for the Indian economy (1985–90). this paper analyses the medium-run effects of (agricultural) trade liberalization. Its focus is on the effects of trade reform on farmers' incentives, because it is often presumed that the lack of adequate incentives constitutes the major constraint on private agricultural investment and the use of modem inputs. The simulation results suggest that, given empirically plausible price response elasticities, the improvement in farmers' incentives consequent upon trade liberalization is unlikely to increase agricultural productivity and real incomes in a broad-based and sustained manner. It is with reference to these results that major technological, social and structural, and organizational barriers to private agricultural investment are discussed and an important role is identified for government intervention in fostering agricultural development.     

Good jobs, bad jobs, and trade liberalization

How do labor markets adjust to trade liberalization? Leading models of intraindustry trade (Krugman (1981), Melitz (2003)) assume homogeneous workers and full employment, and thus predict that all workers win from trade liberalization, a conclusion at odds with the public debate. Our paper develops a new model that merges Melitz (2003) with Shapiro and Stiglitz (1984), so also links product market churning to labor market churning. Workers care about their jobs because the model features aggregate unemployment and jobs that pay different wages to identical workers. Simulations show that, for reasonable parameter values, as many as one-fourth of existing “good jobs” (those with above average wage) may be destroyed in a liberalization. This is true even as the model shows minimal impact on aggregate unemployment and quite substantial aggregate gains from trade.
