Les auteurs commencent par rappeler le cadre théorique de l'analyse économique moderne en matière de tarification des infrastructures. Ils présentent tout particulièrement le principe de la tarification au coût marginal, le raisonnement général qui le fonde et son application au cas...

This paper focuses on decision making under risk, comparing group and individual risk preferences in a lottery-choice experiment inspired by Holt and Laury (2002). The experiment presents subjects with a menu of unordered lottery choices which allows us to measure risk aversion. In the...

We present the results of an experiment that explores the sanctioning behavior of individuals who experience a social dilemma. In the game we study, players choose contribution levels to a public good and subsequently have multiple opportunities to reduce the earnings of the other members of the...

La réflexion engagée au début des années 90 sous l'égide du Commissariat Général du Plan a conduit en 1994 à la publication du rapport "Transports : pour un meilleur choix des investissements" qui conclut sur la nécessité de réformer les procédures d'évaluation des projets...

We study the Downs-Thomson paradox, a situation where an additional road capacitycan cause an overall increase in transport generalized cost and therefore a decrease in welfarefor transport users. To this end, we build an experiment based on a double market-entrygame (DMEG) where users have to...

This paper studies the value of private information in strictly competitive interactions in which there is a trade-off between (i) the short-run gain of using information, and (ii) the long-run gain of concealing it. We implement simple examples from the class of zero-sum repeated games with...

We consider situations in which individuals would like to choose an action which is close to that of others, as well as close to a state of nature, with the ideal proximity to the state varying across agents. Before this coordination game is played, a cheap-talk communication stage is offered to...

This paper examines firms' incentives to commit to a transparent behavior (that precludes bribery) in a competitive procedure modeled as an asymmetric information beauty contest managed by a corrupt agent. In his evaluation of firms' offers for a public contract the agent has some discretion to...

This article asks when communication with certifiable information leads to complete information sharing. We consider Bayesian games augmented by a pre-play communication phase in which announcements are made publicly. We characterize the augmented games in which there exists a full disclosure...
