The international political economy of global inequality

While national inequality has made headlines in recent years, income is far more unequally distributed globally than it is within any state. It is striking that global economic inequality has garnered so little attention in International Political Economy (IPE), given the field's longstanding interest in the distribution of resources and the structure of the global economy. This paper argues that IPE should regard the unequal global distribution of wealth and income as a central research concern and outlines a research agenda for doing so. Drawing on recent work by economists, it argues that global inequality is distinctively political in cause and consequence and sufficiently different from both global poverty and national inequality to constitute a unique object of inquiry. IPE has the theoretical and conceptual tools to study global inequality, but doing so will require bridging divisions between those who consider distributional consequences, though primarily in a national perspective, and those concerned with global hierarchies, but with less regard to national agency and economic policymaking. The effort is worth it, however, given the rich substantive agenda that foregrounding global inequality opens up on a series of topics that have not all (to date) been recognized as the core of the field.
