Welcome to my webpage!

I am Professor (and Director of International Relations) at the Paris School of Economics, University Paris 1 Panthéon-Sorbonne, and Senior Member of the Institut Universitaire de France (IUF), with research affiliations with CEPR, CEPII, IZA, CESifo, Harvard CID, LISER, and European Development Network (EUDN).

I have been a member of Bar-Ilan University until 2013 and held visiting positions at Stanford University (in 2001-03) and at the Harvard Kennedy School of Government (in 2009-11). Since 2008 I coordinate the “Migration and Development” annual conferences jointly organized by the World Bank and the French Development Agency.

My research focuses on the growth and developmental impact of migration and on the economics of immigration, diversity, and refugees’ integration.
