Preference heterogeneity, wage inequality, and trade

We consider individuals who value product variety, and who can be skilled or unskilled as workers. Skilled people prefer to consume skill-intensive goods. We show that under plausible conditions an increase in the relative size of the skilled population increases the relative wage of skilled workers, thereby increasing wage inequality. In our two-country model of trade, an increase in the relative supply of skilled labor in either country increases the relative wage of skilled workers, and hence increases inequality in both countries.     

Relative prices and wage inequality: evidence from Mexico

This paper examines the link between relative goods prices and relative wages during two periods of Mexico's trade liberalization. The relative price of skill-intensive goods rose following Mexico's entrance to the General Agreement and Tariffs and Trade (GATT) in 1986, but fell after Mexico entered the North American Free Trade Agreement (NAFTA) in 1994. This paper adds a band pass filter to two established techniques to compare the relationship between prices and wages. Results from all three approaches are consistent with a positive long-run relationship between relative output prices and relative wages. The band pass filter results suggest that the relevant time frame for the relationship begins after 3-5 years.     

Skill bias, trade, and wage dispersion

Wage ratios between different percentiles of the wage distribution have moved in parallel and then diverged in the U.S. in the last 50 years. In this paper, I study the theoretical response of wage ratios to skill-biased technical change and trade integration. I build a simple model of heterogeneous technology and heterogeneous workers that features complementarities between the quality of ideas and abilities. I show that changes to the skill bias of technology and to trade costs can both reproduce the observed pattern since (i) they have similar asymmetric effects on productive vs. unproductive firms, and (ii) positive assortative matching in the labor market transmits this asymmetry across high and low skill workers. Focusing on the different channels through which skill-biased technical change and trade integration operate suggests ways to disentangle the magnitude of each.     

Inequality and endogenous trade policy outcomes

An enduring puzzle in international economics is why trade interventions are biased in favor of import-competing rather than export sectors and therefore restrict trade. In this paper, we show that if the government's objective reflects a concern for inequality then trade policy generally exhibits an anti-trade bias. Importantly, under neutral assumptions, the mechanism that we analyze generates the anti-trade bias independently of whether factors are specific or mobile across sectors. The mechanism also generates an anti-trade bias between large countries even after they sign reciprocal trade agreements that eliminate any terms-of-trade motivation for the use of trade protection.     

Trade liberalization, wage inequality, and endogenously determined nontraded goods

We examine the boundary between traded and nontraded goods as a channel for trade to impact factor prices. In a two-country, two-factor, continuum-good model, tariffs generate a range of nontraded goods. A tariff reduction has a direct effect to expand a country’s import set and an indirect effect through terms of trade to expand its export set. We show that the export expansion can dominate the import expansion, raising the relative demand for the factor intensively used in production. The result is useful in explaining observed rising wage inequality in developing countries following trade liberalization.     

Voting for pollution policy: the importance of income inequality and openness to trade

This paper analyzes how openness and the distribution of factor ownership interact to determine individual and aggregate demand for pollution policy. Analysis of voter preferences in autarky shows that an increased stake in either the dirty or the clean industry can induce an individual voter to prefer stricter environmental policy. Similarly, the paper shows that poorer voters may be the greener voters within an electorate. The model also reveals that the incidence of pollution policy depends upon a country’s trade regime, with consequences for the direction in which income inequality influences aggregate demand for pollution policy.     

Education bias of trade liberalization and wage inequality in developing countries

The aim of this article is to examine the impact of increased trade on wage inequality in developing countries, and whether a higher human capital stock moderates this effect. We look at the skilled–unskilled wage differential. When better educated societies open up their economies, increased trade is likely to induce less inequality on impact because the supply of skills better matches demand. But greater international exposure also brings about technological diffusion, further raising skilled labour demand. This may raise wage inequality, in contrast to the initial egalitarian level effect of human capital. We attempt to measure these two opposing forces. We also employ a broad set of indicators to measure trade liberalization policies as well as general openness, which is an outcome, and not a policy variable. We further examine what type of education most reduces inequality. Our findings suggest that countries with a higher level of initial human capital do well on the inequality front, but human capital which accrues through the trade liberalization channel has inegalitarian effects. Our results also have implications for the speed at which trade policies are liberalized, the implication being that better educated nations should liberalize faster.     

Trade liberalization and rising wage inequality in Latin America: Reconciliation with HOS theory

The paper puts forward the hypothesis that the transitory effects of trade liberalization on wage inequality can differ from the long-run outcome. In cases where the HOS theory predicts a decline in wage inequality in the long run, a temporary rise can, nevertheless, occur due to (i) the asymmetries in the speed of contraction in the import sector and expansion in other sectors, and (ii) the capital-skill complementarity in production. The asymmetric contraction and expansion causes a transitory capital accumulation that boosts the relative and the real wage of skilled labor due to capital-skill complementarity. Although the long-run HOS fundamentals are, therefore, dominated in the short run by the transient effects arising due to capital-skill complementarity, the observed rise in wage inequality is nonetheless consistent with the HOS theory appropriately extended to a dynamic setting.     

The effect of outward processing trade on wage inequality: the Hong Kong case

This study uses time series analysis to investigate the impact of Hong Kong's increased outward processing trade with the Chinese Mainland on wage inequality. We found a significant positive association between outward processing trade and the wage premium of university graduates over primary school graduates and that over secondary school graduates. Moreover, a standard test showed one-way causality from outward processing trade to the widening of skill wage gap. Furthermore, the increase of outward processing trade is found to both increase the pay for well-educated people and decrease the pay for less well-educated people, thereby widening the wage gap.     

A causal relationship between trade efficiency and economic efficiency: Evidence from dynamic simultaneous equations models

The objective of this study is to examine the causal relationship between economic efficiency and trade efficiency using dynamic panel data in simultaneous equations models for global panel of 50 countries over the period 2000–2014. The study also implements this interrelationship for two groups of countries based on their level of development. Two models applying different factors reflecting countries’ economic and trade policies are proposed to measure the targeted efficiencies using data envelopment analysis method. Evidence from the simultaneous equations models to identify a relationship between economic efficiency and trade efficiency supports the bidirectional causality between them in all three categories of countries. It has been also found that both economic and institutional factors have a significant positive influence on trade and growth performance, with the effect of political factors being especially pronounced for developing countries that suffer from weak institutional capacity. These empirical findings are of particular interest to policy-makers as they help to build sound policies in order to maximize trade performance as well as economic efficiency.     

The Uruguay Round and air pollution: estimating the composition,scale and technique effects of trade liberalization

This paper develops a methodology to estimate the environmental impact of the Uruguay Round trade agreement. The impact is estimated in terms of five air pollutants for both developed and developing countries/regions. The methodology estimates environmental Kuznets curves and uses these in conjunction with FranÇois et al.'s (1995) estimates of Uruguay Round income gains and sectoral production changes, together with sectoral pollution intensities from Hettige et al. (1994). In this manner, composition, scale and technique effects of the Uruguay Round on air pollution are estimated. The monetary cost/benefit associated with the pollution changes is also estimated. Results indicate that emissions of all five pollutants are predicted to increase in developing and transition regions as a result of the Uruguay Round, whilst in developed regions emissions of three pollutants decrease and two increase. The results also suggest that the environmental impact will be considerably greater if the Uruguay Round affects the rate of economic growth.     

Intra-national versus international trade in the European Union: why do national borders matter?

The first objective of this paper is to estimate border effects among European Union countries. In this context, the specification of the gravity equation, together with the choice of the distance measure, are shown to be crucial for assessing the size of the border effect. The second objective is to evaluate the determinants of the cross-commodity variation in national border effects. Contrary to previous findings reported in the literature, we show that trade barriers do provide an explanation. In particular, technical barriers to trade, together with product-specific information costs, increase border effects, whereas non-tariff barriers are not significant. Our results further suggest that these barriers are not the only cause since the spatial clustering of firms is also found to matter.

Exporting under trade policy uncertainty: Theory and evidence

I provide novel evidence for the impact of trade policy uncertainty on exporters. In a dynamic, heterogeneous firms model, trade policy uncertainty will delay the entry of exporters into new markets and make them less responsive to applied tariff reductions. Policy instruments that reduce or eliminate uncertainty, such as binding trade policy commitments at the WTO, increase entry. The predictions are tested on disaggregated, product-level Australian imports with model-consistent measures of uncertainty. The estimates show that growth of exporter–product varieties would have been 7% lower between 1993 and 2001 without the binding commitments implemented after the WTO was formed in 1996. If Australia reduced all its tariffs and bindings to zero, more than half of predicted product growth is accounted by removing uncertainty. These results illuminate and quantify an important new channel for trade creation.     

Trade and inequality in developing countries: a general equilibrium analysis

Developing and newly industrialized countries that have experienced the sharpest increases in wage inequality are those whose export shares have shifted towards more skill-intensive goods. We argue that this can be explained by technological catch-up. We develop this insight using a model that features both Ricardian and endowments-based comparative advantage. In this model, Southern catch-up causes production of the least skill-intensive Northern goods to migrate South (where they become the most skill-intensive Southern goods). This raises wage inequality in both the South and the North. We provide empirical evidence that strongly supports this causal mechanism: Southern catch-up exacerbates Southern inequality by redirecting Southern export shares towards more skill-intensive goods.

Trade liberalization and the environment: The case of intra-industry trade

Abstract

While a large body of literature examines the environmental impact of trade on the environment, this discussion focuses largely on the context of inter-industry trade. Empirical evidence has long suggested that an increasing share of international trade takes the form of intra- rather than inter-industry trade. In an attempt to fill this gap, the present paper uses a price-setting duopoly model of intra-industry trade to highlight the environmental consequences of trade liberalization when oligopolistic rivalry rather than comparative advantage drives international trade. We find that the environmental impact of trade liberalization depends mostly on two factors, namely, on the nature of pollution (i.e. whether it is local, transboundary or global) and on which country liberalizes trade (i.e. whether it is the ‘clean’ country or the ‘dirty’ country).     

Exchange-rate variability and industry trade flows between Malaysia and Japan

This research investigates the exchange-rate risk sensitivity of Malaysian bilateral trade flows with its important trading partner, Japan. To this end, bounds testing approach to co-integration is applied using industry level data over the monthly period 2000–2013. Findings suggest that above the one-third of the total co-integrated export (43.86%) and import (34.54%), industries experiences the ringgit/yen variability effect in the short run. However, this effect sustains in relatively less number of export (14.03%) and import (32.73%) industries in the long run. It is interesting to note that exchange-rate risk boosts trade flows in the majority of these affected industries.     

Endogenous political organization and the value of trade agreements

In a bargaining model of endogenous protection, I introduce fixed costs of political-organization that need to be incurred by capitalists prior to actual lobbying. Unlike Maggi and Rodriguez-Clare [J. Pol. Econ. 106(3) (1998) 575] intersectoral capital mobility is disallowed. Nevertheless, I am still able to obtain their main result that a government with low bargaining power vis-à-vis the import-competing lobby precommits to a free-trade agreement. Further, with high fixed organizational costs, the government prefers to stay out of such agreements. Its maximum bargaining power consistent with signing a trade agreement has an inverse-V-shaped relationship with respect to the size of fixed costs.     

EMU and trade: A PPML re-assessment with intra-national trade flows

This paper examines the EMU effect on trade for the eleven early joiners and Greece relying for the first time on data that include both international and intra-national trade flows, in line with all the microfoundations of the structural gravity model of trade. We find that the overall EMU impact on trade is positive between its members and, specially, for trade between members and non-members. Interestingly, we further show that the effect of the EMU on bilateral trade remarkably differs across countries. For Ireland, Belgium–Luxembourg, Spain, Portugal and Austria, we find robust evidence that EMU has boosted trade both with other members and with third countries, while for Finland, France, Germany, Italy and the Netherlands, the results suggest that only trade with third countries has been enhanced by the EMU. Greece is the only country that shows a negative impact in trade with other EMU members and no effect in trade with non-members. Finally, the results across countries according to the direction of the trade flows (exports versus imports) do not show significant differences in any case.
