Customs data reveal heterogeneity and granularity of relationships among buyers and sellers. A key insight is how more exports to a destination break down into more firms selling there and more buyers per exporter. We develop a quantitative general equilibrium model of firm-to-firm matching that...

During the last two decades, new research has greatly advanced our understanding of the structure of world trade. This article reviews the empirical literature that grew out of this effort, emphasizing the ways in which it relied on theoretical developments

International trade theory is a general-equilibrium discipline, yet most of the standard portfolio of research focuses on the production side of general equilibrium. In addition, we do not have a good understanding of the relationship between characteristics of goods in production and...

The net imports of labor embodied in international trade has been a fairly small and stable share of the US labor force. From this some conclude that trade has not been a major contributor to the income inequality trends. This is a non sequitur. The labor embodied in trade is jointly determined...

The last decade witnessed an explosion of research into the impact of international technology differences on the factor content of trade. Yet the literature has failed to confront two pivotal issues. First, with international technology differences and traded intermediate inputs there does not...

The two models of international trade with developed factor markets -- Heckscher-Ohlin and Specific Factors -- both suffer significant defects. For example, their predictions about the patterns of domestic production and international trade are for the most part either indeterminate or uselessly...
