As waves of migrants have crossed the Mediterranean and the US Southwest border, development agencies have received a de facto mandate: to deter migration from poor countries. Will it work?

With rigorous economic research and practical policy solutions, we focus on the issues and institutions that are critical to global development. Explore our core themes and topics to learn more about our work.
