Xavier Gabaix

Xavier Gabaix is the Pershing Square Professor of Economics and Finance at Harvard University’s Department of Economics, part of the Faculty of Arts and Sciences. He holds a PhD from Harvard University and an undergraduate degree in Mathematics from the École Normale Supérieure in Paris. His research bridges behavioral economics, finance, and macroeconomics, with a focus on bounded rationality, asset pricing, and large economic fluctuations.

Key awards include the Fischer Black Prize (best financial economist under 40), the Bernacer Prize (top European macro-finance economist under 40), and the Lagrange and Allais Prizes. He is a Research Associate at the National Bureau of Economic Research and the Center for Economic Policy Research.

His work explores complexity aversion, sparse dynamic programming, and granular economic shocks. Recent articles address AI applications in central banking, propagation of economic shocks in networks, and behavioral macroeconomic modeling. Gabaix’s research often integrates econophysics principles to explain power-law distributions in financial markets and city size dynamics.
