International political economy (IPE) is an acaemic discipline within the social sciences that analyzes international relations in combination with political economy. As an interdisciplinary field it draws on many distinct academic schools, most notably political science and economics, but also sociology, history, and cultural studies. The academic boundaries of IPE are flexible, and along with acceptable epistemologies are the subject of robust debate. This debate is essentially framed by the discipline's status as a new and interdisciplinary field of study.
