This paper examines the cross-country income and welfare consequences of trade-induced human capital (dis-)accumulation. The model is based on heterogeneous workers who make educational decisions in the presence of complete markets. When such heterogeneous workers invest in schooling, high type agents earn a surplus from their investment. In the presence of cross-country differences in skill-augmenting technology, trade shifts this surplus to rich countries that can use skills more efficiently. Thus, while the static gains from trade may lead to convergence, the dynamic gains from trade occur to initially rich countries, thus leading to cross-country divergence of income and welfare. The second part of the paper endogenizes world prices, documenting that as trade liberalization concentrates skills in countries with a high level of skill augmenting technology, it thereby increases the effective global supply of skilled labor. Despite the resulting decline in the price of skill-intensive goods, trade is shown to be skill-biased.

This study provides empirical evidence that trade increases on-the-job human capital accumulation by estimating the effect of home country openness on estimated returns to home country experience of U.S. immigrants. The positive effect of trade on on-the-job human capital accumulation remains significant when controlling for GDP, educational attainment, and institutional quality. It is not the result of self-selection, heterogeneity in returns to experience, English-speaking origin, or cultural background. The effect persists when restricting the sample to non-OECD countries, thereby resolving the theoretical ambiguity of whether trade increases or decreases learning-by-doing. The role of trade in generating economic growth is therefore likely to be more important than generally considered.

This work focuses on researching and establishing the importance of human capital and innovation as determinants of competitive advantages in international trade—in the context of rapidly evolving technological advancement, globalization, and economic integration. The processes that accompany the shift from industrial economics to a knowledge-based economy are currently the object of interest of both scientists, politicians, investors and entrepreneurs. In many countries, the traditional sources of socioeconomic development, such as low labor costs, availability of inexpensive raw materials, and favorable geographic location are waning. These economies are searching for new sources of competitive advantage that will allow for maintaining growth, among other things by boosting participation in international trade. The book explores non-traditional drivers of competitiveness in both theory and practice. First, chapters 1 through 4 present theoretical and methodological aspects of the relationships among international trade, human capital and innovation. Here the authors address the controversy associated with the concept of competitiveness itself and its measurement, while paying special attention to the political development of comparative advantages related to international trade. The second part of the monograph, chapters 5 through 8, is of empirical nature. This section contains case studies of selected countries that represent models of various national innovation systems. Finally, the theoretical and practical aspects are integrated, allowing policymakers and financial and business leaders to consider how their decisions can influence their countries’ competitive positions through their investments in innovation and human capital.

November 1998 Empirical analysis confirms that a policy of trade openness has a strong positive impact on economic growth. The accelerated accumulation of physical capital accounts for more than half this growth. Enhanced technological transmissions and improvements in the quality of macroeconomic policy each account for about 20 percent of the effect of openness on growth. Wacziarg investigates the links between trade policy and economic growth using data from a panel of 57 countries from 1970-89. This is the first attempt to empirically evaluate, in a cross-country context, the respective roles of various theories of dynamic gains from trade in explaining the observed positive impact of trade openness on economic growth. Wacziarg uses a new measure of trade openness, based on the effective policy component of trade shares, in a simultaneous equations system aimed at identifying the effect of trade policy on several determinants of growth. The results suggest that a policy of trade openness has a strong positive impact on economic growth. The accelerated accumulation of physical capital accounts for more than half this effect. Enhanced technological transmissions and improvements in the quality of macroeconomic policy each account for about 20 percent of the impact of trade openness on growth. This decomposition is robust to alternative specifications and time periods. Wacziarg also successfully tests whether the empirical methodology captures all or most of the effects of trade policy on growth. The lack of statistically significant results concerning several other channels may be due to measurement problems. The black market premium may be a weak proxy for the efficiency of the price system. Moreover, international technological transmissions are very hard to measure, so there may be a downward bias in the estimates based on the manufactured exports channel, and a corresponding overstatement of other channels. This paper-a product of the Development Prospects Group, Development Economics-is part of a larger effort in the Bank to analyze the relationship between openness and economic growth.
