I am a professor of economics at the University of Paris Nanterre, a member of UMR7235-EconomiX and of the Cercle des économistes, and a scientific adviser at the French Institute for Economics (IFE). My research focuses on the long-term dynamics of economies and structural policies. I am particularly interested in defining sustainable economic growth, which would enable living standards to continue to rise while preserving the environment. My other two areas of interest concern long-term structural changes such as demographic ageing and international migration.
