IPE is the study of a problématique, or set of related problems. The traditional IPE problématique includes analysis of the political economy of international trade, international finance, North-South relations, multinational corporations, and hegemony. This problématique has been broadened in recent years as many scholars have sought to establish a New IPE that is less centered on International Politics and the problems of the nation-state and less focused on economic policy issues. These scholars seek to create a new discipline of IPE that would transcend the perceived limits International Politics and International Economics as fields of study and research.
