We study the implications of trade liberalizations on real GDP and real consumption in a widely-used class of models in international trade. We calculate the change in aggregate quantities in response to a reduction in international trade costs, following as closely as possible the procedures...

What are the consequences of international trade on income inequality---measured as the relative wage of skilled to unskilled workers, the skill premium? To address this question we formulate a multi-country model of international trade that introduces skill intensity differences across firms...

We study the response of factor allocation and the skill premium to trade liberalizations in a model that combines exogenous determinants of comparative advantage--that result from sectoral productivity and factor endowment differences across countries--with endogenous determinants of...

The production of capital equipment is concentrated among a small group of countries, and many countries import a large share of their equipment. If capital-skill complementarity is an important feature of technology, international trade may have important effects on the skill premium through...

Capital equipment - such as computers and industrial machinery - embodies skill-biased technology, in the sense that it is complementary to skilled labor. Most countries import a large share of their capital equipment, and by doing so import skill-biased technology. In this paper we develop a...

We examine the implications of workhorse trade models for how aggregate productivity, real GDP and real consumption, as measured by statistical agencies, respond to changes in trade costs. In a range of models, changes in measured productivity are equal to the inverse of an export-share weighted...

Do theoretical welfare gains from trade translate into aggregate measures of economic activity? We calculate the changes in real GDP and real consumption that result from changes in trade costs in a range of workhorse trade models, following the procedures outlined by statistical agencies in the...

We provide an assignment model to decompose changes in between-group wage inequality into changes in the composition of the workforce, the productivity/demand for tasks, computerization, and labor productivity. The model incorporates comparative advantage between many groups of workers, many...
