Info for Authors


International Organization seeks to publish the best and most innovative scholarly manuscripts available on international political and economic relations. A study that does not emphasize any international (or cross-border) phenomenon—for example, as a major cause or effect—falls outside the journal’s domain.

Additionally, IO features articles that contribute to the improvement of general knowledge or empirical theory defined broadly. Although we may publish a manuscript designed to propose a solution to a current world problem, we prefer to publish those that also apply theoretical ideas and findings or address general questions debated in scholarly publications.

Editorial Team

Jon Pevehouse at the University of Wisconsin is the journal's editor. He is assisted by three associate editors, Michael Barnett of George Washington University, Lars-Erik Cederman of the Swiss Federal Institute of Technology ETH, and by Andrew Kydd of the University of Wisconsin. Elana Matthews is the managing editor.

Our primary role as editors is to encourage the best work to be submitted to IO, and then to manage a fair process of review. In that regard, IO continues to favor no particular research tradition, theoretical school, or methodological approach. Rather, its hallmark is the theoretical and methodological diversity now so obvious in its traditional core subfield of international political economy (IPE), as well as in international relations (IR) more generally.
