This course provides an intermediate level study of international trade theory and policy. We will discuss various aspects of international trade at a fairly abstract and rigorous level. The issues that will be addressed are, among others, the fundamental gains from trade, the implications of imperfect competition for trade patterns and welfare, how firms of different sizes and productivities engage in trade and investment, and justifications for policies that restrict trade. Also covered are the World Trade Organisation (WTO) and regional and bilateral trade agreements.
