The main objective of the course is to introduce students to classical, neoclassical and more contemporary theories of international trade. The policy implications of international trade theory also constitute a significant component of the course. It is a principal aim of this course to enable students to learn some major topics, such as: Comparative advantage; gains from international trade; the role of relative-factor endowments in shaping the patterns of trade across countries; the role of product and process innovations in international trade; theoretical and policy-related implications of economies of scale, imperfect competition, and intra-industry trade; instruments and purposes of trade policies implemented by governments; market- and welfare effects of trade policies; and arguments for and against trade policies.
