Abstract
For many years International Political Economy (hereafter IPE) was something of a misfit in the study of international politics in particular and political science – indeed, in the social sciences in general. It was never at ease with the economist, for whom it was not ‘real economics’; it was far too ‘economistic’ for scholars of international relations; too ‘international’ for scholars of political science; and largely unnoticed by normative political philosophy. As a consequence, it tended to sit at the periphery of most social science ‘disciplines’. For a range of reasons to be discussed in this com‐panion essay to political science, this situation has changed dramatically over the last two decades. IPE is now deemed more salient to the study of politics and international relations and even some branches of economics. Pertinently, the interactions between IPE and philosophy are becoming similarly important of late.
