Julien Combe

Julien Combe is a tenured Professor at the Department of Economics of École Polytechnique, where he holds a permanent membership at CREST (Center for Research in Economics and Statistics), a joint research center between ENSAE, ENSAI and École Polytechnique. He is also affiliated with the Institut des Politiques Publiques and the Center for Economic Policy Research (CEPR).

His academic journey includes:

• PhD in Economics from Paris School of Economics (2017), supervised by Professor Olivier Tercieux
• Habilitation à Diriger les Recherches (HDR) completed June 2023
• Visiting Scholar at Columbia University (2015-2016)
• Research Associate at University College London (2017-2019)

Combe specializes in theoretical and empirical market design with applications spanning education systems (kindergarten assignment, school choice, teacher allocation) and healthcare (kidney exchange programs). His research uniquely bridges rigorous economic theory with practical policy implementation, frequently collaborating with French government agencies to design efficient allocation mechanisms. As an organizer of CREST's Microeconomic Seminar, he fosters academic exchange in his field.

His publication pattern reveals consistent contributions to solving real-world matching problems through sophisticated economic models. Recent work focuses on dynamic assignment mechanisms, kidney exchange optimization, and equitable teacher distribution systems, demonstrating both theoretical innovation and practical relevance. His research methodology combines formal mathematical modeling with empirical validation, making significant contributions to economic science while directly informing public policy decisions.

Combe actively engages with policymakers through:

• Multiple policy briefs for the Institut des Politiques Publiques
• Technical contributions to France's kidney exchange program
• Algorithm design for teacher assignment systems
• Public commentary on school admission platforms like Parcoursup

His work has received substantial media attention in France, appearing in Le Monde, Libération, France Info, and other major outlets, demonstrating the societal impact of his research on allocation mechanisms affecting millions of citizens.
