Trade and the distribution of human capital

We develop a two-country, two-sector model of trade where the only difference between the two countries is their distribution of human capital endowments. We show that even if the two countries have identical aggregate human capital endowments the pattern of trade depends on the properties of the two human capital distributions. We also show that the two distributions of endowments also completely determine the effects of trade on income inequality. We also look at a simple majority voting model. It turns out autarky and free trade with and without compensation may be the voting outcome.     

On the similarity of country endowments

We study the production side of the Heckscher-Ohlin model empirically. The evidence we present suggests that the endowments of countries around the world are too dissimilar for all countries to be able to produce the same set of goods. In contrast, the endowments of the rich OECD countries are sufficiently similar, so that these countries do not have to specialize in different subsets of goods. Our findings have implications for a variety of issues ranging from the trade and wages debate to economic development. Our analysis relies on the lens condition of Deardorff [Journal of International Economics 36 (1994) 167-175] that compares country endowments with sectoral factor inputs. We mainly focus on the production factors capital and labor. We test the robustness of the results with different data sets and with corrections for international differences in productivity and human capital. We confirm the similarity of the developed OECD countries with skilled and unskilled labor data. We also investigate in detail the implications of measurement error and sectoral aggregation.     

Trade and imperfect competition in general equilibrium

This paper employs a multi-industry general equilibrium model of oligopolistic competition, free market entry and trade in which capital is used to establish firms and labor is used for production. We show that both absolute and relative endowments matter for the pattern of trade. We demonstrate that market entry to each industry is either too excessive or too moderate while the effect on firm size is ambiguous. If countries are sufficiently symmetric, trade will increase the wage–rental ratio in both countries. Furthermore, trade will increase per-capita consumption in capital-intensive industries and reduce it in labor-intensive industries. Nevertheless, trade will be mutually welfare-improving under relatively mild conditions.     

Export diversification: How much does the choice of the trading partner matter?

This paper studies how a country's export diversification varies across destination markets. It develops an extension of the Romalis (2004) model which yields two testable predictions. According to the first, exports between similarly endowed countries (“South–South” and “North–North”) are more diversified than exports between differently endowed countries (“South–North” and “North–South”). The second implication is that, for given countries' production patterns, low bilateral trade costs lead to greater export diversification. These predictions find empirical support in a panel of 102 trade partners and 4998 HS-6 industries over the period 1995–2007. Results show that similarities between trading partners in physical capital, land and human capital endowments per worker are associated with more diversified bilateral exports. Exports are also more diversified when bilateral trade costs are relatively low.     

Investment liberalization and international trade

This paper estimates the cross-price elasticity of exports with respect to investment costs for bilateral relations between 36 countries. We show that the effect of reducing foreign direct investment costs on exports depends on country characteristics and trade costs as predicted by the [Markusen, 1997] and [Markusen, 2002] model. When countries differ in relative factor endowments and trade costs are low, investment liberalization stimulates exports, whereas when countries are similar in terms of relative factor endowments and size, and trade costs are moderate to high, investment liberalization reduces exports.     

Export Productivity and Specialisation: A Disaggregated Analysis

The paper analyses export productivity and trade specialisation in China, Brazil, India and South Africa. The investigation calculates a time‐varying export productivity measure using highly disaggregated product categories. The modelling shows that export productivity is determined by real income and human capital endowments. But the empirical analysis also reveals significant differences in export productivity and specialisation for countries with comparable per capita income levels.     

The Asymmetric Effect of Endowments on Vertical Intra‐industrial Trade

(1238) J. Milgram‐Baleix and Ana I. Moro‐Egido This paper investigates the determinants of vertical Spanish intra‐industry trade with developed and developing countries. We empirically test the comparative advantage explanation. To do so, we build physical, human and technological capital stocks. On average, when using OLS techniques, differences in endowments are a limitation for vertical intra‐industry trade. Using quantile regression techniques, we observe that this negative effect decreases in absolute terms as vertical intra‐industry trade flows increase and, in some cases, the impact becomes positive for the upper tails, thus supporting the view of a reduced version of the comparative advantage explanation. Our results provide interesting insights into Spain and emerging countries. A large part of Spanish trade already takes place on an inter‐industry basis or consists of exporting low quality products in exchange for similar products of a higher quality range, in particular with European countries but more surprisingly with emerging countries. Our study shows that high quality exports and horizontal intra‐industry trade are mainly driven by proximities of demand and technological capital while low quality exports share most determinants of inter‐industry trade.     

Capital, technology, and specialization in the neoclassical model

The paper studies the effects of technology and capital stock on trade using simulation. For this purpose, the paper develops and evaluates a model that is distinguished by its use of the Eaton-Kortum framework to explain intra-industry trade instead of the usual Armington assumption. It is found that the magnitudes and in many cases signs of the effects of capital stock and technology on specialization are very country-specific. This implies that the regression studies that estimate cross-country average effects have limited value. Looking at the volume of trade, the paper finds that capital endowments and industry-level comparative advantages have little effect on the volume of trade — the reduced inter-industry trade between more similar countries is compensated by increased intra-industry trade. Producer heterogeneity, on the other hand, has a significant effect on the volume of trade. The paper evaluates the accuracy of the model's forecasts by performing historical simulations for 1975-95, with the results showing that the model's predictions are accurate.     

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.     

International portfolios, capital accumulation and foreign assets dynamics

Despite the liberalization of capital flows among OECD countries, equity home bias remains sizable. We depart from the two familiar explanations of equity home bias: transaction costs that impede international diversification, and terms of trade responses to supply shocks that provide risk sharing, so that there is little incentive to hold diversified portfolios. We show that the interaction of the following ingredients generates a realistic equity home bias: capital accumulation and international trade in stocks and bonds. In our model, domestic stocks are used to hedge fluctuations in local wage income. Terms of trade risk is hedged using bonds denominated in local goods and in foreign goods. In contrast to related models, the low level of international diversification does not depend on strongly countercyclical terms of trade. The model also reproduces the cyclical dynamics of foreign asset positions and of international capital flows.     

The role of endowments,technology and size in international trade: new evidence from product-level data

Using product-level trade data, we empirically investigate the export patterns of more than 150 countries in their exports to the USA, Brazil, India, and Japan. We document strong evidence that exporters specialize according to their relative factor endowments, technology, and economic size. More developed, capital abundant countries are found to export products of higher unit values and a wider range of products to developed, emerging and developing markets. More developed, economically larger, and technologically advanced countries are also the major exporters of new products, spanning a wide range of product categories with high unit values. Our findings provide important insights into the macro phenomenon that a large proportion of the global trade takes place among developed economies, and that the latter are also major exporters to developing markets.

Accounting for quality differences in human capital and foreign direct investment

This paper empirically investigates how cross-country differences in the quality of human capital, as they are captured by the conventional measures of international test score differences, influences the patterns of foreign direct investment. Using panel data covering 32 countries during the period between 1985 and 2004, this paper finds that a host country's quality of educational attainment plays an independent role in attracting foreign direct investment. In particular, the quality of human capital influences horizontal foreign direct investment, even after accounting for the roles of skill and factor endowments, trade costs, investment costs, and country-size and income effects.     

Determinants of Export Diversification Around the World: 1962–2000

Using a large dataset for 79 countries covering the period 1962–2000, this study analyses the main determinants of export diversification (concentration). We explore the role of several factors and we use three different indicators of export concentration. We find robust evidence across specifications and indicators that trade openness induces higher specialisation. In contrast, financial development does not seem to help countries to diversify their exports. Looking at the effects of exchange rates, in some of the results, a negative effect of real exchange rate volatility on export diversification is detected, but no significant effects of exchange rate overvaluation. There is also evidence that human capital accumulation contributes positively to diversify exports and that increasing remoteness tends to reduce export diversification. We also explore the role of terms of trade shocks. Most of the results suggest an interesting interaction between this variable and human capital: improvements in the terms of trade tend to concentrate exports, but this effect is lower for those countries with higher levels of human capital. This evidence suggests that countries with higher education can take advantage of positive terms of trade shocks to increase export diversification.     

Credit constraints, equity market liberalizations and international trade

This paper provides evidence that credit constraints are an important determinant of international trade flows. I exploit shocks to the availability of external finance and examine the impact of equity market liberalizations on the export behavior of 91 countries in the 1980-1997 period. I show that liberalizations increase exports disproportionately more in financially vulnerable sectors that require more outside finance or employ fewer collateralizable assets. This result is not driven by cross-country differences in factor endowments and is independent of simultaneous trade policy reforms. Moreover, it obtains with equal strength in the full panel of countries as well as in both panel and event-study analyses of countries which removed capital controls during the sample period. Finally, the effects of liberalizations are more pronounced in economies with initially less active stock markets, indicating that foreign equity flows may substitute for an underdeveloped domestic financial system. Similarly, opening equity markets has a greater impact in the presence of higher trade costs caused by restrictive trade policies.     

Who Supports Free Trade in Latin America?

This paper examines individual trade policy preferences across 17 countries in Latin America. The focus is on whether skilled or unskilled workers are more likely to support liberalised trade and on whether country characteristics, such as factor endowments, alter the preferences of skilled and unskilled workers. Based on the standard Heckscher‐Ohlin model and the Stolper‐Samuelson theorem, wage inequality in developing countries will decrease under free trade and unskilled workers will benefit. We find that on average skilled workers are more likely than unskilled workers to support free trade in Latin American countries. Separate country regressions reveal that this pattern is only statistically significant in 8 out of 17 Latin American countries. However, there are no countries in our sample in which unskilled workers are statistically more likely to support free trade than skilled workers, not even in the lowest skill‐endowed country in the sample. We also find that people from Latin American countries with higher GDP, faster growth, more cropland and a longer period of time since reform were more likely on average to support free trade.     

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.     

Openness,inequality and poverty: Endowments matter

Using tariffs as a measure of openness, this paper finds consistent evidence that the conditional effects of trade liberalization on inequality are correlated with relative factor endowments. Trade liberalization, measured by changes in tariff revenues, is associated with increases in inequality in countries well-endowed with highly skilled workers and capital or with workers that have very low education levels. Similar, although less robust, results are also obtained when decile data are used instead of the usual Gini coefficients. Taken together, the results are strongly supportive of the factor-proportions theory of trade and suggest that trade liberalization in poor countries where the share of the labor force with little education is high raises inequality. Simulation results also suggest that relatively small changes in inequality as measured by aggregate measures of inequality, like the Gini coefficient, are magnified when estimates are carried out using decile data.

Increasing returns,monopolistic competition,and international trade

This paper develops a simple, general equilibrium model of noncomparative advantage trade. Trade is driven by economies of scale, which are internal to firms. Because of the scale economies, markets are imperfectly competitive. Nonetheless, one can show that trade, and gains from trade, will occur, even between countries with identical tastes, technology, and factor endowments.
