On Tuesday, 14 April 2026, a tribute will be paid to the memory of the economist Roger Guesnery, Honorary President of PSE-Paris School of Economics and Professor Emeritus at the Collège de France, holding the Chair in ‘Economic Theory and Social Organisation’. His work contributed to advances in research on the functioning of public services: asymmetric information between the State and citizens, international coordination in the fight against global warming, rational expectations of agents, and the ‘second-best’ equilibrium, among other topics.
Roger Guesnery co-founded DELTA (Département et laboratoire d’économie théorique et appliquée – Department and Laboratory of Theoretical and Applied Economics) with François Bourguignon. At the request of François Furet, then President of the EHESS, he was also the first head of the doctoral programme ‘Economic Analysis and Policy’ from 1981 to 1991. He served as Chair of the Board of Governors of the Paris School of Economics, and was a member of the Conseil d’analyse économique (Economic Analysis Council) and of the editorial boards of several renowned professional journals. He was Co-Editor-in-Chief of Econometrica (from 1984 to 1989), President of the European Economic Association (1994), President of the Econometric Society (1996) and President of the Association Française de Sciences Économiques (2003). He was awarded the CNRS Silver Medal (1993) and appointed as an Honorary Foreign Member of the American Economic Association (since 1997) and as a member of the American Academy of Arts and Sciences.
The event brought together, in the Daniel Cohen Amphitheatre of the Paris School of Economics, around forty economics researchers, including two Nobel Prize winners and several professors from the Collège de France, the EHESS and the world’s leading universities.
The speeches, which were often moving, provided an opportunity to appreciate Roger Guesnery’s human qualities, as well as the vitality of French research in economics – and especially in econometrics – which has already been honoured with five Nobel Prizes.
