I study a repeated game in which a patient player wants to win the trust of some myopic opponents but can strictly benefit from betraying them. His benefit from betrayal is strictly positive and is his persistent private information. I characterize every type of patient player's highest...

I study reputation models in which information about the long-run player's past behavior is dispersed among short-run players. I identify two challenges to reputation building when such information is aggregated via the short-run players' actions. First, when the long-run player's action can...

We study the monotonicity of sender's equilibrium strategy with respect to her type in signalling games. We use counterexamples to show that when the sender's payoff is non-separable, the Spence-Mirrlees condition cannot rule out equilibria in which the sender uses non-monotone strategies. These...

We study the interaction between a potential offender's (principal ) incentive to commit crimes and the potential victims' (agents) incentive to report crime. The probability of crime and the credibility of reports are endogenously determined in equilibrium, and the principal is convicted if...
