The course introduces students to the theories and analytical frameworks relating to decision- making and negotiation in international economic relations and helps them to apply these to particular cases. It includes coverage of the respective roles of the main actors, institutional settings and processes involved in domestic decision-making and international negotiation, and their interaction with each other. In this changing world, technological developments, fresh actors, new issues and the breakdown of distinctions between foreign and domestic policy have undermined the monopoly of diplomats over international relations. Foreign services have been overtaken by these changes and are no longer up to the challenges of defending and promoting national interests. Nevertheless, an effective foreign service is ever more essential to a country's security, economic and social welfare. Understanding the process of decision making in foreign economic policy is thus crucial for various students studying international relation, government, politics, or economics. This course is structured in several sections. First, we attempt to describe the theoretical principles of economic diplomacy. The second part invokes the main working tools of economic diplomacy, institutional aspects, and methods. The third section attempts to make a comparative analysis of some models of economic diplomacy, including country studies and global governance institutions. Finally, the fourth part allows the students to experience their own simulation exercise of an economic diplomacy summit.
