Firm Heterogeneity and the Two Sources of Gains from Trade
AbstractRecent empirical work identi.es two main channels through which consumers benefit from trade. Trade liberalization lowers prices, while it raises product variety. This paper develops the first model that connects both channels and interprets their interaction. It shows that heterogeneity in firm productivity is the source behind both. Upon liberalization efficient exporters enter, pushing out the least efficient domestic firms. Two countervailing forces emerge, both stylized facts. Liberalization leaves a moreconcentrated market. But exporters o¤er more variety than the .rms that they replace. Remarkably, total variety unambiguously increases. Exploration of comparative statics leads to an intuitive explanation.
