Welcome

The Séminaire parisien de Théorie des Jeux is an open, inter-institutional, multi-disciplined seminar which covers all fields of game theory. It takes place on Monday from 11:00 to 12:00 am at Institut Henri Poincaré, 11 rue Pierre et Marie Curie, Paris 5ème. MAP

You will find the program for the current academic year on the page 2026/2027 and the program for past years on the page Archives.

The junior seminar welcomes PhD students in game theory to present their work.  You will find the program for the current academic year on the page Junior Seminar 2026/2027.

Title: Efficiency in Sequential Games with Sequential Transfers (joint with Nathaniel Neligh, University of Tennessee). 

Abstract: Given any finite-player finite-action perfect information sequential game, if players can offer action-conditional utility transfers to the moving player sequentially at every history ("bid" for actions), every Markov perfect equilibrium results in a utilitarian-efficient outcome, maximizing the sum of all players' utilities. In equilibrium players bid "pivotally," offering just enough to change which action is the most valuable, taking into account the bids and utilities of other players.
