Nous modélisons cette relation comme un contrat réciproque où chaque joueur a la possibilité de prendre des engagements conditionnels aux engagements des autres joueurs. Nous nous distinguons du reste de la littérature sur les contrats réciproques en supposant que les sanctions ne peuvent ˆêtre appliquées dans le cas où la coopération prend fin. Nous caractérisons l’ensemble des allocations qui peuvent ˆêtre implémentées par des équilibres bayésiens parfaits. Nous utilisons cette caractérisation pour montrer que l’ensemble des allocations soutenables avec contrats réciproques est plus grand que l’ensemble des allocations soutenables avec un m´mécanisme d’incitation centralise dans lequel le planificateur ne peut pas punir les non-participants. Ce résultat provient de la capacité des joueurs dans le cadre de contrats réciproques `a transmettre des informations partielles sur leurs types au moment où ils offrent des contrats. Nous discutons des implications de notre analyse pour modéliser la collusion entre plusieurs agents qui interagissent avec le même principe."
"en" => "We study an incomplete information game in which players can coordinate their actions by contracting among themselves. We model this relationship as a reciprocal contracting procedure where each player has the ability to make commitments contingent on the other players’ commitments. We differ from the rest of the literature on reciprocal contracting by assuming that punishments cannot be enforced in the event that cooperation breaks down. We fully characterize the outcomes that can be supported as perfect Bayesian equilibrium outcomes in such an environment. We use our characterization to show that the set of supportable outcomes with reciprocal contracting is larger than the set of outcomes available in a centralized mechanism design environment in which the mechanism designer is constrained by his inability to enforce punishments against non-participants. The difference stems from the players’ ability in our contracting game to convey partial information about their types at the time they offer contracts. We discuss the implications of our analysis for modelling collusion between multiple agents interacting with the same principal."

If resale is not allowed and the bidder valuations are drawn from a strictly convex distribution function, the symmetric equilibrium (where all bidders use the same cutoff) is less efficient than a class of two-cutoff asymmetric equilibria. Existence of these equilibria without resale is sufficient for existence of similarly constructed two-cutoff equilibria with resale. Moreover, the equilibria with resale are “more asymmetric” and (under a sufficient condition) more efficient than the corresponding equilibria without resale."

"fr" => "We study information flows in an organization with a top management (principal) and multiple subunits (agents) with private information. Under centralized communication, eliciting the agents' information may induce the principal to manipulate aggregate information, which obstructs an effective use of information. Under hierarchical communication, the principal concedes more information rent due to loss of control, but is able to use the agents' information more effectively. The trade-off between the organizational structures depends on the likelihood that the agents are efficient. Centralized communication is optimal when such likelihood is low. Hierarchical communication, by contrast, is optimal when it is high."
