The Review of International Organizations publishes original scientific contributions in the entire field of political economy, with a focus on the policies and structure of international organizations, such as the WTO, World Bank, NATO, WHO, the European Court of Human Rights, and the UN. The journal includes studies based on modern economic, political economic, and international relations theories, using quantitative or qualitative methods. Papers should ideally put forward a new theory and provide a rigorous empirical test of this theory, but the RIO allows for a trade-off between the two.
