His educational background includes:

• Ecole Polytechnique
• Ecole des Ponts et Chaussées (as Ingénieur des Ponts et Chaussées)
• PhD in economics from EHESS and the European Doctoral Programme (1992)

Professor Jehiel's research spans several areas within economic theory. His primary interests include bargaining, auction theory, mechanism design, market design, game theory, and bounded rationality. His work often bridges theoretical economics with practical applications in market design and behavioral economics. He has made significant contributions to understanding strategic behavior in various economic settings, from public procurement to financial markets and voting systems. His research demonstrates a consistent focus on designing efficient economic mechanisms while accounting for behavioral considerations.

His recent publications show an evolving research agenda that increasingly incorporates algorithmic approaches and behavioral insights into traditional economic frameworks. The publications span theoretical developments in game theory and mechanism design while addressing practical applications in public procurement, financial markets, and voting systems. His work demonstrates interdisciplinary connections between economics, computer science, and cognitive science, particularly in the 2025 paper on Q-learning applications to market making.

Professor Jehiel has received significant recognition for his contributions to economic science:

• Fellow of the Econometric Society
• Fellow of the European Economic Association
• Fellow of the Society for the Advancement of Economic Theory
• Fellow of CEPR
• Former holder of an ERC advanced grant

Throughout his distinguished career, Professor Jehiel has held several prestigious editorial and governance positions. He served as co-editor of Econometrica, one of the most respected journals in economics, and was a council member of both the Econometric Society and the Game Theory Society. His research has been supported by competitive grants, including an ERC advanced grant, reflecting the significance and impact of his theoretical contributions. His academic service demonstrates leadership within the economics profession and commitment to advancing economic science through rigorous theoretical work.

Professor Jehiel's scholarly activities appear to be primarily theoretical research conducted through individual work and collaborations with other economists. His publications in top discussion paper series and policy-focused outlets like VoxEU indicate active engagement with both academic and policy-relevant economic questions, particularly in areas related to market design, auction theory, and behavioral economics.
