We develop a new analytical framework for both cross-border services trade and services trade through foreign affiliates, based on heterogeneous firms operating under oligopoly. This leads to direct predictions about choice of services delivery (mode of delivery) at the firm level, and about the...

International trade models typically assume that producers in one country trade directly with final consumers in another. In the real world, of course, trade can involve long chains of potentially independent actors who move goods through wholesale and retail distribution networks. These...

Working with a panel dataset of of OECD countries over the decade 1994-2004, we examine linkages between cross-border trade and FDI in the service sectors. We first develop a consistent analytical framework for the application of the gravity model jointly to services trade and commercial...

This paper reviews the new approach to international trade based on firm heterogeneity in differentiated product markets. This approach explains a variety of features exhibited in disaggregated trade data, including the higher productivity of exporters relative to non-exporters, within-industry...

This paper reviews the empirical evidence on firm heterogeneity in international trade. A first wave of empirical findings from micro data on plants and firms proposed challenges for existing models of international trade and inspired the development of new theories emphasizing firm...

This paper examines the determinants of intra-firm trade in U.S. imports using detailed country-product data. We create a new measure of product contractibility based on the degree of intermediation in international trade for the product. We find important roles for the interaction of country...

Antidumping actions in the United States and EU are known to be linked to macroeconomic conditions. In part, this is because positive injury findings may be easier to make in a downturn. We explore the evidence for Mexico, one of the main ‘new’ antidumping-using countries. Injury...

The theoretical literature on endogenous growth and international trade suggests that comparative advantage is endogenous. Sector-specific learning by doing and technology transfer respectively provide reasons why initial patterns of international specialization may persist or exhibit mobility...

Most of the large tariff reductions achieved in multilateral trade negotiations have involved tariff-cutting formulas such as the ‘Swiss’ formula. Wide variations in initial tariff rates between active participants, however, call for new approaches under the Doha Development Agenda. This...

The theoretical result that there are welfare gains from trade is a central tenet of international economics. In a class of trade models that satisfy a "gravity equation", the welfare gains from trade can be computed using only the open economy domestic trade share and the elasticity of trade...
