Players have privacy concerns that may affect their choice of actions in strategic settings. We use a variant of signaling games to model this effect and study its relation to pooling behavior, misrepresentation of information, and inefficiency

We analyze repeated games in which players have private information about their levels of patience and in which they would like to maintain the privacy of this information vis-a-vis third parties. We show that privacy protection in the form of shielding players' actions from outside observers is...

We study the implementation challenge in an abstract interdependent values model and an arbitrary objective function. We design a mechanism that allows for approximate optimal implementation of insensitive objective functions in ex-post Nash equilibrium. If, furthermore, values are private then...
