Gilles Saint-Paul obtained his Ph.D. from MIT in 1990. Since then he has worked on issues related to unemployment, long-term economic growth, political economy and European labour market institutions. He has published extensively on these issues, in particular Dual Labor Markets: A macroeconomic perspective (MIT Press, 1996) and The Political Economy of Labour Market Institutions (Oxford University Press, 2000). His recent work has dealt with the implications of new technologies and intellectual property rights for growth, and the dynamics of income distribution. He has been Professor of Economics at DELTA in Paris from 1990 to 1997, and at Universitat Pompeu Fabra in Barcelona from 1997 to 2000. Since then he is a Professor at Toulouse University and a Visiting Professor at Birkbeck College, London.

He has served as a consultant for the IMF, the Spanish government, and the Swedish government. He is a member of the Conseil d’Analyse Economique, an advisory council to the French Prime Minister, and is Programme Director of the Centre for Economic Policy Research in London in the area of Labour Economics.
