We consider strategic issues in one-to-one matching with externalities. We show that no core (stable) mechanism is strategy-proof, extending an impossibility result of Roth (1982) obtained in the absence of externalities. Moreover, we show that there are no limits on successful manipulation of...

In this paper, we extend Aumann's (1974) well-known solution of correlated equilibrium to allow for a cost of disobedience for each player. Calling the new solution costly correlated equilibrium (CCE), we derive the necessary and sufficient conditions under which the set of CCE strictly expands...

Recent experimental studies find excessive truth-telling in sender–receiver games. We show that this phenomenon is robust to the random intervention of a truthful regulator. In addition, intervention significantly increases the excessive trust of receivers while the overall percentage of...

This study analyzes a continuous-time N-agent Brownian hidden-action model with exponential utilities, in which agents' actions jointly determine the mean and the variance of the outcome process. In order to give a theoretical justi¯cation for the use of linear contracts, as in Holmstrom and...

This paper asks whether or not it is possible to induce agents to good behavior permanently via regulators' reputations and attain perpetual social efficiency. We propose and analyze a repeated incomplete information game with a suitable payoff and monitoring structure between a regulator...

This paper analyzes optimal contracts in a linear hidden-action model with normally distributed returns possessing two moments that are governed jointly by two agents, who can observe each others' effort levels and draft enforceable side-contracts on chosen effort levels and realized returns....
