The core subjects of trade theory are the pattern and volume of trade: which goods are traded by which countries, and how much of those goods are traded. The first part of the paper discusses evidence on comparative advantage, with an emphasis on carefully connecting theory models to data...

Classic trade questions are reconsidered by generalizing a factor-proportions model to multiple countries, multi-stage production, and country-specific trade costs. We derive patterns of production specialization and trade for a matrix of countries that differ in relative endowments (columns)...

In contemporary data, the measured factor content of trade is far smaller than its predicted magnitude in the pure Heckscher-Ohlin-Vanek framework, the so-called 'missing trade' mystery. We wonder if this problem has been there from the beginning: that is, we ask if the Heckscher-Ohlin theory...

The standard neoclassical model of trade theory predicts that international specialization will be jointly determined by cross-country differences in relative factor endowments and relative technology levels. This paper uses duality theory combined with a flexible functional form to specify an...

Study of the factor content of trade has become a laboratory to test our ideas about how the key elements of endowments, production, absorption and trade fit together within a general equilibrium framework. Already a great deal of progress has been made in fitting these pieces together....

Within developing and newly industrialized countries, rising wage inequality is both common and highly correlated with export growth. This is incompatible with the Stolper-Samuelson theorem, but suggestive of a role for technological catch-up. We develop this insight using a model that features...

This study examines the effect of NAFTA, an instance of North-South trade liberalization, on returns to skill in Mexico. Mexico is abundant in low-skill workers relative to the US and Canada, and so, by the Hecksher-Ohlin-Samuelson trade model, NAFTA ought to have raised the relative earnings of...

In recent years, Spain has received unprecedented immigration flows. Between 2001 and 2006 the fraction of the population born abroad more than doubled, increasing from 4.8% to 10.8%. For Spanish provinces with above-median inflows (relative to population), immigration increased the high school...

This paper provides new evidence on the determinants of individual trade policy preferences using an individual-level data set identifying both stated trade policy preferences and potential trade exposure through several channels for the United States in 1992. There are two main empirical...
