Direct Investment Liberalization,Commodity Trade and Income Distribution: What Can the WTO do?

This paper analyzes a model of two-way movement of physical capital, and examines the effects of direct investment liberalization on resource allocation, income distribution and commodity trade. If either country or both countries liberalizes investment under exogenously given commodity prices, some factor owners in a country will gain but some others will lose. If capital movement affects commodity prices, all factor owners in a country may be better off after multilateral investment liberalization. In these cases, it will be much easier for the home country to sign an agreement liberalizing investment flows.     

Trade balance dynamics and exchange rates: In search of the J‐curve using a structural gravity approach

This paper uses a structural gravity approach, specifying currency movements as trade cost component to derive an empirical trade balance model, which incorporates multilateral resistance terms and accounts for the cross‐country variation in the exchange rate pass‐through into import and export prices. The model is estimated using quarterly bilateral trade flows between 47 countries over the period 2010Q1 to 2017Q2, disaggregated into 97 commodity groups. Our results support the existence of an “aggregate” J‐curve, pooled over commodity groups; at the same time they point to considerable heterogeneity in the trade balance dynamics across industries below the surface of aggregate data.     

International student migration to Germany

The past decades have witnessed an impressive growth of international student mobility. This article presents first empirical evidence on international student migration to Germany, one of the most important destination countries for international students worldwide. While previous research in the field has mainly used data on international trade in educational services, I use a novel approach that analyzes student mobility as a form of migration, using data on international student migrants. An augmented gravity equation is the basis for the theoretical and empirical framework. I also provide extensive sensitivity checks of the empirical results and estimates using both the usual log-linearized and a multiplicative specification of the gravity equation, following recent work by Santos Silva and Tenreyro (Rev Econ Stat 88(4): 641–658, 2006). The results provide evidence for the importance of distance—a familiar result from the empirical migration literature. Unlike for international migration on the whole, the importance of disposable income in the home country does not seem to be too big for students, and student migrant flows from politically unfree countries are significantly lower.     

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.     

GROWTH AND WELFARE EFFECTS OF WORLD MIGRATION

Using a two‐bloc endogenous growth model calibrated to two generic sending and receiving countries of equal size, we assess the growth and welfare impact of world migration flows of different skill compositions. The sending country (East) has a lower total factor productivity and a lower endowment of skilled labour. Migration can induce two growth‐enhancing effects: an efficiency effect from the more efficient use of labour in the receiving country (West) and a sectoral reallocation effect from a fall in the host country skilled–unskilled wage rates. Despite growth gains, there are both winners (migrants, the representative Western non‐migrant household) and losers (the representative Eastern household remaining). Remittances can see the latter group joining the winners.     

Spillovers from Foreign Exporters

We develop a general equilibrium model of international trade with heterogeneous firms that accounts for productivity spillovers transmitted by foreign exporters. Everything else equal, stronger spillovers increase welfare. We embed the model framework into a trade policy scenario where countries strategically set inter‐country variable trade costs for the trading partner. In the strategic Nash‐equilibrium policy, governments trade‐off welfare gains from protectionism and those that are due to spillovers from foreign exporters. The equilibrium degree of protectionism is decreasing in the strength of the spillover. Policy coordination induces welfare gains but these gains can be hump‐shaped in the spillover strength.     

Factor Heterogeneity,Factor Market Imperfection and Trade

This paper develops a tractable model of examining how factor heterogeneity and imperfect factor market interact for determining a pattern of trade. Institution plays a crucial role for the interaction. In my work, firm productivity is defined as a composition of factor productivity and technology. Thus, input selection should affect the pattern of Melitz’s intra-industry allocation due to the incurring transaction cost. For a simple model, I assume two factors (labor and capital) and two sectors, which are relatively less institution-dependent and relatively more institution-dependent. When the economy is open, effect of the transaction cost on income distribution is more drastic for an institutionally underdeveloped country. Depending on institutional quality, the economic openness reallocates resource across countries through job creation or job destruction. The job turnovers redistribute income between heterogeneous labors within countries. The income redistribution is catalyzed by international mobility of capital. As a result, income disparity is widened between the institutionally developed country and the institutionally underdeveloped country. This paper can contribute to the literature of institution and international trade.     

Foreign Aid under Quantitative Restrictions: Welfare Effects and International Factor Mobility

Using a two‐country, general‐equilibrium model of international trade, this paper incorporates pre‐existing quantitative trade restrictions and international factor mobility into the transfer problem analysis. The effects of foreign aid on the welfare of both the donor and recipient nations are identified under each form of quantitative trade restriction: quotas and voluntary export restraints (VERs). In doing so, this paper identifies conditions under which international transfers are strictly Pareto‐improving (i.e. increase global welfare). A central result of this analysis is the direct welfare effect of a transfer received by a nation with quota‐constrained (VER‐constrained) imports is enhanced (may be enhanced) by a worsening of the recipient’s terms of trade.     

Ancestry and international trade

This paper examines whether the relatedness of populations across the world shapes international trade flows. Using data on common ancestry for 172 countries covering more than 99% of global trade, we document that country pairs with weaker ancestral relationships are less likely to trade with each other (extensive margin) and, if they do trade, they exchange fewer goods and smaller volumes (intensive margin). The effect of ancestry is robust to a vast array of micro-geographic control variables and mitigated, yet still sizable and significant, when controlling for other measures of cultural distance as well as for current migrant stocks.     

Trade and Tradability: Exports, Imports, and Factor Markets in the Salter-Swan Model

We extend the Salter-Swan model to include both factor markets and semi-traded goods. In our model, changes in relative factor prices depend on changes in world commodity prices, factor endowments, and the trade balance. In contrast, only changes in world commodity prices can affect factor prices in the neoclassical trade model. The inclusion of semi-traded goods weakens the magnification effect in both the Stolper-Samuelson and Rybczynski theorems. When imports and domestic goods are poor substitutes, a characteristic of some commodities in developing countries, the sign of the Stolper-Samuelson theorem is reversed.     

Human Capital,Technology, and Specialization: A Comparison of Developed and Developing Countries

GDP GDP function framework, and apply it to panel data. We find that factor supplies and openness to trade are important factors influencing the structure of production, but we also uncover interesting differences in results across output sectors and groups of countries. In addition, we find evidence that Hicks-neutral technological differences do not affect specialization. Finally, our results on the effect of openness highlight the sources of conflicts between developed and developing countries in multilateral trade negotiations.

Regionalism and Multilateral Trade Liberalization with Asymmetric Countries

The paper examines the impact of regionalism on the process of multilateral trade liberalization when countries are asymmetric. The author uses a three‐country, three‐good, competing exporters model, with countries being symmetric in everything but their discount factors. The equilibrium regional agreement is found to be a customs union between a patient and an impatient country and that the impact of regionalism depends on the discount factors. The impact of regionalism on multilateral trade liberalization depends critically on which countries engage in regionalism.     

Foreign Factor Ownership and Optimal Tariffs

In the presence of foreign factor ownership tariffs change not only the terms of (goods) trade but also income flows between countries. Assume that only the home country owns factors abroad. Then the optimal tariff is negative if and only if foreign factor ownership entails trade-pattern reversals. Trade-pattern reversals are neither a necessary nor a sufficient condition for a negative optimal tariff if the foreign country owns factors in the home country. Changes in the home country's tariff shift the foreign country's offer curve. This adds a new dimension to optimal tariff analysis.     

FACTOR ENDOWMENTS, TRADE LIBERALIZATION, AND THE FUTURE OF APEC TRADE PATTERNS

The heads of state of Asia-Pacific Economic Cooperation (APEC) nations have committed member nations to remove all barriers to trade both among themselves and with respect to the rest of the world by 2020. The present paper uses a simple econometric model of bilateral trade flows based on country size, relative factor endowments, and trade barriers of importing as well as exporting countries to estimate the shares by country of origin in imports of each of the 16 major APEC countries and the rest of the world for each of 45 commodity groups comprising world trade in commodities. The estimates reveal that APEC trade would be expanded by 13% with complete liberalization of tariff barriers, by an additional 5% if nontariff barriers are also removed, and by another 4% if the rest of the world would also remove all barriers to trade. Variants on this base scenario show that such trade expansion could be substantially reduced were trade liberalization, capital growth, or both to be reduced in the countries affected by the Asian financial crisis.

Free Trade, Growth, and Convergence

Can trade liberalization have a permanent affect on output levels, and more important, does it have an impact on steady-state growth rates? The model emphasizes the role that knowledge spillovers emanating from heightened trade can have on income convergence and growth rates during transition and over the long run. Among the results of the model, unilateral liberalization by one country reduces the income gap between the liberalizing country and other, wealthier countries. From the long-run growth perspective, unilateral (and multilateral) liberalization generates a positive impact on the steady-state growth of all the trading countries.     

Tariffs,quotas, and voluntary export restraints with endogenous labor supply

This paper develops a two-good, small-country, general equilibrium trade model with endogenous labor supply and wage taxes, and where trade is restricted by a tariff, or an import quota, or VERs. Within this framework we derive (i) the employment and welfare effects of the three types of trade restrictions, (ii) the price effect of an import quota and VERs, and (iii) the shadow price of foreign exchange under each type of trade restriction. The present results are compared to those where (i) factor supplies are fixed, and (ii) perfect international capital mobility exists.     

Migration,trade and spillover effects

This paper identifies a new channel through which migrants can affect the import demand of goods in the host country. In migrating from origin to destination country, migrants observe a change in the price of the bundle of consumable goods. In particular, the migration decision can imply a reduction in the price of imported goods for the consumption bundle of migrants: emigration towards less (tariff) protected countries allows the consumption of products that were prohibitively protected in the origin countries of migrants. To test this channel we estimate the import demand effect of migrant groups coming from third high (tariff) protected countries. Our empirical results strongly confirm this channel and suggest a new perspective about how migration can affect welfare and trade in destination countries.     

Labour‐market institutions and their impact on trade partners: A quantitative analysis

Recent theoretical literature studies how labour market reforms in one country can affect labour market outcomes in other countries, thereby rationalizing widely held policy beliefs and empirical evidence. But what is the quantitative relevance of such spillover effects? This paper combines two recent workhorse models: the canonical search‐and‐matching framework and the heterogeneous firms international trade model. Qualitatively, the framework confirms that labour market reforms in one country benefit its trading partners, replicating the stylized facts. However, when wages are bargained flexibly, the model quantitatively underestimates the correlation of structural unemployment rates across countries. Introducing some degree of real wage rigidity remedies this problem.     

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.     

Multilateral Comparisons of Productivity, Terms-of-Trade and Factor Accumulation

This paper proposes a new approach for multilateral comparisons using index numbers. The new approach combines two recently-proposed innovative techniques to examine differences among economies at various levels. The Minimum Spanning Tree algorithm, based on the idea of minimizing substitution bias of bilateral comparisons, provides a possible ordering for panel data. Making use of the suggested ordering, bilateral Törnqvist price and quantity indexes are calculated and multilateral indexes are obtained by chaining. An index-number based approach is then used to decompose the differences in GDP at the bilateral level. Different sources that contribute to the differences in GDP are considered: productivity differences, terms of trade differences, factor endowments differences and domestic output price differences. The newly formed indexes are base-invariant which provides strong support for using the technique for multilateral comparisons. An illustration of the technique using data from China and four OECD countries is included.
