"This paper reviews the recent theoretical literature on heterogeneous firms and trade, which emphasizes firm selection into international markets and reallocations of resources across firms. We discuss the empirical challenges that motivated this research and its relationship to traditional...

This paper develops a new framework for examining the distributional consequences of international trade that incorporates firm and worker heterogeneity, search and matching frictions in the labor market, and screening of workers by firms. Larger firms pay higher wages and exporters pay higher...

Recent research in international trade emphasizes the importance of firms' extensive margins for understanding overall patterns of trade as well as how firms respond to specific events such as trade liberalization. In this paper, we use detailed U.S. trade statistics to provide a broad overview...

We examine US workers' employment and earnings before and after trade liberalization with China. Among workers initially employed in manufacturing, we find substantial and persistent declines in both outcomes, with indirect exposure via input-output linkages exacerbating the negative effects of...

Mexico's experience before and after trade liberalization presents a challenge to neoclassical trade theory. Though labor abundant, it nevertheless exported skill-intensive goods and protected labor-intensive sectors prior to liberalization. Post-liberalization, the relative wage of skilled...
