Recent empirical evidence has shown that firms/plants producing similar goods react very differently to international forces. Some firms export, while others only serve their domestic market. Among the former, a small subset export to a large number of international markets while a substantial proportion of exporters only serve a single foreign market. Other firms (multinationals) choose to serve customers in foreign markets via local subsidiaries. Trade, and international forces more generally, thus induce important composition changes within industries, leading to substantial measured changes in economic performance. The lectures will survey the newer empirical literature based on firm-level studies of trade, and develop the analytical framework for general equilibrium models of trade with heterogeneous producers. The lectures will then cover applications (both theoretical and empirical) of these models to different subfields of international economics.
