This project examined the relationship between the institutional authority of international organizations (IOs) and the dynamics of institutional overlap by asking two questions: What are the implications of differences in IO authority for institutional overlap? And given conditions of institutional overlap, which IO characteristics lead to more or less authority?
In cooperation with Yoram Haftel (Hebrew University Jerusalem), these questions were approached through quantitative analyses and case studies of overlap among international/regional organizations in Africa.
This project was funded by the Ministry of Science and Culture of Lower Saxony’s Research Cooperation Lower Saxony – Israel grant between 2018 and 2023.
