A new methodology is developed to determine the extent to which import competition has been responsible for labor displacements and wage movements inspecific, allegedly trade-impacted sectors. The procedure involves the estimation of reduced-form wage and employment equations by sector. These...

Recent research has emphasized firm heterogeneity as a source of comparative advantage. Combining this approach with labor market frictions and worker heterogeneity provides a framework for studying the impact of trade on unemployment and inequality. This paper reviews this approach and reports...
