It is well known that when agents are fully rational, compulsory public insurance may make all agents better off in the Rothschild and Stiglitz (1976) model of insurance markets. We find that when sufficiently many agents underestimate their personal risks, compulsory insurance makes low-risk...

When a principal and an agent operate with simple contracts, at equilibrium, renegotiation will occur after the action is taken. Also, since renegotiation makes incentive contracts non-credible, the principal may prefer non-renegotiable monitoring options. Current literature does not fully...

The issue of how players' model of a game may evolves over time is largely unexplored. We formalize this issue for games with perfect information, and show that small-probability model deterioration may upset the complete-model backward induction solution, possibly yielding a Pareto-improving...

Motivated by real-world information economics problems and by experimental findings on overconfidence, this paper introduces a general epistemic construction to model strategic interaction with incomplete information, where the players’ self-perception may be mistaken. This allows us to...

This paper applies mechanism design to con ict resolution. We determine when and how unmediated communication and mediation reduce the ex ante probability of con ict in a game with asymmetric information. Mediation improves upon unmediated communication when the intensity of con ict is high, or...
