Wage inequality in developing countries: South–South trade matters

The relationship between trade liberalization and inequality has received considerable attention in recent years. The major purpose of this study is to present new results on the sources of wage inequalities in manufacturing taking into account South–South (S–S) trade. Globalization has not only lead to increasing North–South (N–S) trade, but it has also changed the direction and composition of trade as more trade is carried out among developing countries. In this study, we find that increasing wage inequality is associated more with the South–South trade liberalization than with the classical trade liberalization with northern countries. A part of this increasing wage inequality due to S–S trade comes from the development of N–S trade relationship in S–S trade that increases wage inequality in middle-income developing countries. This study also seeks to shed some light on the link between the direction of trade and technological change. We explore the fact that S–S trade leads to a technological change biased toward skill-intensive sectors more than N–S trade. This indirect effect increases wage inequality for all developing countries, but it is more important in low-income countries.     

Testing creative destruction in an opening economy

This paper analyses the relationship between trade liberalization and economic growth using a Schumpeterian framework of technological innovation and applies it to sector‐level South African data. The framework examines direct and indirect effects of trade liberalization on productivity growth. Indirect impacts operate through a differential impact of trade liberalization on firms conditional on their distance from the international technological frontier. Results confirm positive direct impacts of trade liberalization. Results confirm also that the greatest positive impact of trade liberalization will be on sectors that are close to the international technological frontier and that experienced a low level of product market competition before liberalization.     

资本账户开放与国际金融冲击的传导——基于DSGE模型的分析

本文在动态随机一般均衡的框架下,建立了一个包括贸易部门和非贸易部门的小型开放经济模型,系统研究和比较资本管制与资本账户开放两种情况下,国外金融冲击、出口需求冲击对中国经济的不同影响和传导机制,并检验资本账户开放情形下应对国际冲击时不同货币政策规则的有效性。结果发现：当资本账户开放时,一国受到国外冲击的波动幅度远大于资本管制的情况;资本管制和资本账户开放对国际金融冲击传导机制的关键差异在于贸易部门与非贸易部门的互动关系,具体表现为劳动力转移的差异;在资本账户开放后,面对不同形式的国际冲击,货币数量型规则和混合型规则均能有效熨平经济波动。     

Does economic openness affect liberal and electoral democracy in a different way? Empirical evidence from developing countries

The focus of this paper was to empirically analyze the impacts of economic liberalization on the liberal and electoral democracy in a sample of 106 less developed and developing countries over the period 1970–2016. The economic relationship between these countries and the global trade and the financial system generates a crucial question of to what extent political conditions are affected by this changing relation. To test these relationships, this paper uses V‐Dem's liberal democracy and electoral democracy indices and nine economic liberalization variables. Utilizing two‐step system dynamic panel GMM estimation indicates that trade openness and economic globalization, de facto strongly affects electoral democracy.     

Trade Gains, Paretian Transfer and the Tragedy of the Commons

Consider trade liberalization between two countries, each of which produces two private goods and provides on a voluntary basis one public good (the common). In these circumstances, what are the consequences of trade liberalization on the production of the public good and on welfare in both countries? Using a Ricardian framework, we first show that the opening of trade increases the opportunity cost of producing the public good in both countries and will therefore reduce the aggregate supply of the public good. On the other hand, at the autarky equilibrium, only one country supplies the public good, the other “free rides”. The analysis of the welfare incidence of the opening of trade then reveals that the country which provides the public good under autarky always enjoys a welfare gain from trade while the free rider under autarky does not unless the terms of trade are sufficiently in its favour to compensate for the reduction in the supply of the common. Finally, if all countries involved in trade liberalization can without cost coordinate their supplies of the common, then the implementation of the first-best outcome is shown to be possible with a conditional Paretian transfer scheme.     

Water on Fire: Gains from Electricity Trade

In light of the ongoing liberalization of electricity trade in the Nordic countries, and perhaps in Northern Europe, we argue that gains from electricity trade may be different from those traditionally associated with comparative advantages and economies of scale. In particular, we consider gains arising from the exploitation of technological complementarities between hydro and thermal systems. Our theoretical framework highlights essential features of the two systems and allows for an analysis of effects of trade. We study three trading regimes, which may arise either endogenously or because of trade regulations: day–night power exchange, seasonal energy banking and unbalanced trade. The analysis suggests that gradual trade liberalization may be costly.     

Preferential versus multilateral trade liberalization and the role of political economy

In this paper we analyze the effect of the freedom to pursue preferential trade liberalization, permitted by Article XXIV of the GATT, on country׳s incentives to participate in multilateral negotiations and on feasibility of global free trade. We present a model, in which countries choose whether to participate in preferential or multilateral trade agreements under political pressures from domestic special interest groups. We show that heterogeneity in political preferences across countries plays an important role in determining the relative merits of preferential and multilateral approaches to trade liberalization. On one hand, the opportunity to liberalize preferentially may be necessary to induce countries with strong political motivations to participate in multilateral free trade negotiations. On the other hand, when countries share similar political preferences, multilateral free trade that would have been politically supported otherwise becomes unattainable if countries can pursue preferential liberalization.     

Trade liberalization,technology, relative factor supplies and the relative wage: evidence from the South

There is much controversy about the role that trade liberalization, technological change and relative factor supplies have played in bringing about changes in the relative wage of the unskilled workers. Much of the empirical work on this issue has focused on the industrial countries and paid little attention to developing countries. To fill this gap, this study develops a special data set to examine the relative wage behaviour of a large number of developing countries. An empirical model based on the theory is used to test different explanations of the relative wage change. As predicted by the technology explanation, the empirical analysis in the study finds a significant negative link between the relative wage of unskilled workers and the technology index. The analysis, however, does not find a significant role for labour supplies or trade liberalization in determining the relative wage of unskilled–skilled workers.     

How deep is your love? A quantitative spatial analysis of the transatlantic trade partnership

This paper explores the quantitative effects of trade liberalization envisioned in a transatlantic trade and investment partnership (TTIP) between the United States and the European Union. We use a quantitative trade model that, in contrast to other works, features consumptive and productive uses of land and we allow for labor mobility and a spatial equilibrium. Our calibration draws mainly on the world input–output database (WIOD). The eventual outcome of the negotiations is uncertain. Tariffs in E.U.–U.S. trade are already very low, however, so that an agreement will have a major impact only by eliminating nontariff barriers. These are extremely hard to quantify. We address these uncertainties by considering a corridor of trade‐liberalization paths and by providing numerous robustness checks. Even with ambitious liberalization, real income gains within a TTIP are in the range of up to 0.46 percent for most countries. The effect on outside countries is typically negative, yet even smaller. Taking land into account scales down the welfare effects strongly. Interestingly, we find that all German counties derive unambiguous welfare gains even though the model allows for negative terms‐of‐trade effects. Our analysis also implies that in order to arrive at the same welfare gains as under a TTIP, a multilateral liberalization would have to be much more ambitious for the U.S. than for the E.U.     

Impact of Regional Economic Integration in East Asia

The current study evaluates the economy wide impact of trade liberalization in the ASEAN region along with China, Japan and Korea (ASEAN + 3) by the year 2020 using the GTAP framework. The study also assesses the environmental impact of the trade liberalization in the region focusing on the seven environmental indicators (CO₂, CH₄, N₂O, BOD, COD, Suspended Solid and Industrial Waste). The result shows that the countries under agreement (ASEAN + 3) will benefit with increased output, expansion of trade and welfare due to trade reforms. Further, the integration will increase the global welfare, although the regions not under agreement in the world will show a decline in output growth. Vietnam will be gaining with the highest output growth among the ASEAN region; however, the impact on the environment would not be favourable. The environmental impact reveals a mixed outcome for participating countries under the agreement. The paper provides useful insight in pursuing greater trade liberalization among the countries under the study.     

Intra‐industry Trade Liberalization: Why Skilled Workers are More Likely to Support Free Trade

This paper presents a theoretical model and empirical analysis that connects the prevalence of intra‐industry trade with increased wage inequality from trade liberalization in both skilled and unskilled labor abundant countries. The Stolper–Samuelson effect is incorporated into an intra‐industry trade liberalization (intra‐ITL) hypothesis where skilled labor opposes protectionism in all countries engaged in intra‐industry trade because skilled workers gain at the expense of unskilled workers from multilateral trade liberalization within the skill‐intensive sector. We examine empirical evidence on whether skilled individuals are more supportive of trade liberalization than unskilled individuals across 31 countries with different levels of intra‐industry trade and skill endowments. We find that the extent to which countries engage in intra‐industry trade in high‐tech commodities is strongly linked with the intensity of opposition to protection by skilled labor. Regression results strongly support our hypothesis that skilled workers, almost everywhere, are more likely to support free trade.     

TRANSPORTATION INFRASTRUCTURE INVESTMENTS AND TRADE LIBERALIZATION*

This paper examines the gains from cooperative agreements on transportation infrastructure investments when there are terms of trade and technological spillovers between countries. In a two ‐country model, cooperation on investment levels will result in a lower level of transport costs. However, the cooperative equilibrium may have a higher or lower level of infrastructure investment between the partner countries in the case of preferential liberalization. The paper also addresses the desirability of linking trade and infrastructure agreements when investment choices can be used strategically.     

Trade liberalization in environmental goods

Trade negotiations have started to pay attention to liberalization in environmental goods (EGs), whose production may require dirty intermediate goods. We construct a two-country trade model to explore the effects of trade liberalization in EGs on the local pollution, the global environment and welfare in the presence of such an environmental conundrum. We find that countries do not necessarily benefit from trade liberalization in EGs in the absence of an environmental policy. With the assistance of an upstream pollution tax, trade liberalization in EGs improves each country's welfare. This result holds independent of whether the upstream market is competitive or not, or whether we have upstream trade across countries. For asymmetric countries, trade liberalization in EGs improves the world welfare and the welfare for the country if it has a smaller demand for EGs; or experiences less damage from the production of dirty inputs; or values environment improvement more.     

Endogenous Growth and Trade Liberalization Between Small and Large Countries

The paper combines insight from new trade theory and R&D-based endogenous growth models to argue that there are ambiguous growth effects of trade liberalization between countries that differ in terms of the size of their home markets. In particular, trade liberalization may reduce R&D incentives in countries with low purchasing power without invoking parallel increases in countries with high purchasing power. The paper also considers the case of imperfect international knowledge spillovers, and demonstrates that complete trade liberalization may affect the growth rate negatively.

International trade and consumption network externalities

This paper studies the effects of trade liberalization in the presence of consumption network externalities. The framework is applicable to the choice of network products and sheds light on the debate on globalization and culture. In an extended Ricardian model of international trade the paper shows that: (i) trade is not Pareto inferior to autarky if the free trade equilibrium is unique; (ii) trade is not Pareto superior to autarky if both countries are diverse (network competition) under free trade, but can be if each country is homogenous (network monopoly); (iii) and when multiple free trade equilibria exist everybody in a country can lose from free trade if that country is homogenous under autarky. Consumers of imported network goods tend to gain, while consumers of exported network goods tend to lose from trade liberalization.     

Regional versus Multilateral Trade Liberalization,Environmental Taxation,and Welfare

The paper considers trade between identical countries with imperfectly competitive markets, and compares the impacts of regional and multilateral tariff reduction on strategic environmental taxation and welfare. While both forms of trade liberalization increase production and consumption in tariff‐reducing countries, regionalism also reduces production in a non‐participating country and may decrease its consumption. Consequently, regionalism and multilateralism change pollution tax and welfare in the tariff‐reducing countries in similar ways when pollution is local, but in dissimilar ways for global pollution. When pollution is global, regionalism is likely to be preferred to multilateralism for the establishment of free trade among countries.     

Differentiated Products,Divided Industries: Firm Preferences over Trade Liberalization

The recent focus on firms in international trade suggests two conjectures about preferences over trade policy – only the most productive firms should support freer trade, and industries can be internally divided over reciprocal liberalization. This paper clarifies the content and scope of these claims. The most productive firms are generally not the greatest beneficiaries from trade liberalization and may oppose further liberalization due to increased competition in export markets from compatriot firms. Exporting industries will feature no support for trade if foreign competition is too strong or barriers too unequal. The key analytic factor generating intra‐industry division is product differentiation, both directly, by increasing export opportunities for less efficient firms, and by inducing home market effects wherein larger countries are more competitive. The implications of these findings for the distributional effects of liberalization and the study of trade politics are discussed.     

Income,taxes and employer pension contributions

This paper empirically examines the effects of a change in foreign trade regime on productivity growth. Based on a Generalized Leontief factor demand function system, total factor productivity growth (TFPG) rates are calculated for the Turkish rubber industry during a substantial trade liberalization in the 1980s: TFPG was significantly higher following trade liberalization. Technological change was the major contributor to this growth. When a panel data estimation technique is used to explain technological change, the effects of trade liberalization become clearer: a one percentage point increase in the protection level led to more than a one percentage point (1.27) decline in the technological change rate.
