We measure the "new" gains from trade reaped by Canada as a result of the Canada-US Free Trade Agreement (CUSFTA). We think of the "new" gains from trade of a country as all welfare effects pertaining to changes in the set of firms serving that country as emphasized in the so-called "new" trade...

We develop a general equilibrium model of monopolistic competition and trade based on indirectly additive preferences and heterogenous firms. It generates markups independent from destination population but increasing in destination per capita income, as documented empirically. Trade...

In a standard multi-sector, heterogeneous-firm trade model the effect of tariffs on entry, especially in the presence of production linkages, can reverse the traditional positive optimal-tariff argument. We construct and employ a new, large, disaggregated tariff dataset and then apply a...

This paper examines the microstructure of import markets and the division of the gains from trade among consumers, importers and exporters. When exporters and importers transact through anonymous markets, double marginalization and business stealing among competing importers lead to lower...

In a general equilibrium product-cycle model, lower trade barriers increase Southern purchasing power, which lifts long-run growth by increasing the profit from innovation. In the short run, factors of production must be reallocated inside firms, which lowers the opportunity cost of innovation,...

We review a recent body of theoretical work that aims to put numbers on the consequences of globalization. A unifying theme of our survey is methodological. We rely on gravity models and demonstrate how they can be used for counterfactual analysis. We highlight how various economic...
