What is the effect of immigration on native labor-market outcomes? An extensive literature identifies the differential impact of immigration on natives employed in jobs that are more exposed to immigrant labor (supply exposure). But immigrants consume in addition to producing output. Despite...

The theory of comparative advantage is at the core of neoclassical trade theory. Yet we know little about its implications for how nations should conduct their trade policy. For example, should import sectors with weaker comparative advantage be protected more? Conversely, should export sectors...

International trade has experienced a Ricardian revival. In this article, we offer a user guide to assignment models, which we will refer to as Ricardo-Roy (R-R) models, that have contributed to this revival.

This paper develops tools and techniques to study the impact of exogenous changes in factor supply and factor demand on factor allocation and factor prices in economies with a large number of goods and factors. The main results of our paper characterize sufficient conditions for robust monotone...

This paper develops tools and techniques to analyze the determinants of factor allocation and factor prices in economies with a large number of goods and factors. The main results of our paper characterize sufficient conditions for robust monotone comparative statics predictions in a Roy-like...
