International trade policy analysis has tended to focus on the production side of general equilibrium, with policies such as a tariff or carbon tax affecting international and internal income distributions through a Heckscher-Ohlin nexus of factor intensities and factor endowments. Here I move...

We show in a multi-sector, heterogeneous-firm trade model that the effect of tariffs on entry, especially in the presence of production linkages, can reverse the traditional positive optimal tariff argument. We then use a new tariff dataset, and apply it to a 189-country, 15-sector version of...

Regional trade agreements must specify domestic-content rules (rules of origin) that define the conditions under which a good qualifies as 'domestic' and so may be freely traded within the block. The paper analyzes such rules, focussing in particular on oligopolistic industries in which foreign...

Producer services such as managerial and engineering consulting can provide domestic firms with the substantial benefits of specialized knowledge that would be costly in terms of both time and money for domestic firms to develop on their own. These intermediate services are often non-traded, or...

This paper explores the relationship between exchange rate pass-through and market share for monopolistically competitive exporters. Under fairly general assumptions we show that pass-through should be high for exporters based in a country with a very large share of total destination market...

We argue that trade in intermediate inputs, or 'global production sharing,' is a potentially important explanation for the increase in the wage gap between skilled and unskilled workers in the U.S. and elsewhere. Using a simple model of heterogeneous activities within an industry, we show that...

A theoretical model is developed and applied to the North American auto industry, motivated by the possibility of US-Mexico free trade. Special features of the model include (1) significant scale economies at the plant level, (2) imperfect competition among firms, (3) joint ownership of plants...
