Public policy and economics expert James Levinsohn has been tapped to lead Yale’s newly formed Jackson Institute for Global Affairs, University President Richard Levin announced Monday. Before his appointment to the institute, Levinsohn — a professor at the University of Michigan who focuses on international economics, industrial organization, economic development and applied econometrics — had agreed to join the faculty of the School of Management as a professor of economics and management. Levinsohn, whose appointment takes effect Feb. 1, has lived and worked in Senegal, Botswana and South Africa, doing research on areas such as the impact of HIV/AIDS on unemployment and school attendance in South Africa. The Jackson Institute, established in April 2009, will bring new faculty to the area of international relations and international studies, in addition to offering courses connected to global affairs and expanded career counseling in all of Yale’s schools.
