This course examines the role of global business as an actor in international relations. It reviews the political and economic theories that seek to explain the rise of global business, paying attention in particular to International Relations and International Political Economy theories (realism, liberalism, Marxism), but also covering the main economic explanations of MNCs. Thereafter, the course examines the interaction between global business and states in international relations. This involves the study of corporate power and how to conceptualise it in IPE, the study of state-firm bargaining over investment decisions, and the regulation of global business by states and international governance institutions. The final part of the course considers the role that global business plays in selected global policy areas: economic development, environmental protection and human rights.
