This course covers various trade theories and policies and apply them to real-world trade issues. Theoretical models include classical Ricardian, neoclassical Heckscher-Ohlin, specific-factors models, and the recent developments on strategic trade models as well as trade models with imperfect competition. Policy issues include tariffs, quotas, voluntary export restraints, and other commercial trade strategies. In addition, topics on free trade areas and customs unions and the implications for the current regional trade integration or disintegration will be discussed.
