This paper studies the enforcement abilities of authorities with a limited commitment to punishing violators. Commitment of resources su±cient to punish only one agent is needed to enforce high compliance of an arbitrary number of agents. Though existence of other, non-compliance equilibria is...

We study how the presence of multiple participation opportunities coupled with individual learning about payoff affects the ability of agents to coordinate efficiently in global coordination games. Two players face the option to invest irreversibly in a project in one of many rounds. The project...

Players repeatedly face a coordination problem in a dynamic global game. By choosing a risky action (invest) instead of waiting, players risk instantaneous losses as well as a loss of payoffs from future stages, in which they cannot participate if they go bankrupt. Thus, the total strategic risk...

Agents at the beginning of a dynamic coordination process (1) are uncertain about actions of their fellow players and (2) anticipate receiving strategically relevant information later on in the process. In such environments, the irreversibility of early actions plays an important role in the...

We show by example that communication can cause common knowledge acquisition to fail. In the absence of communication, agents acquire approximate common knowledge of some parameter, but with communication they do not.

We study coordination failures in many simultaneously occurring coordination problems. Players encounter one of the problems but have the outside option of migrating to one of the remaining ones. Drawing on the global games approach, we show that such a mobile game has a unique equilibrium that...

We study learning in a large class of complete information normal form games. Players continually face new strategic situations and must form beliefs by extrapolation from similar past situations. We characterize the long-run outcomes of learning in terms of iterated dominance in a related...

We consider a common investment project that is vulnerable to a self-fulfilling coordination failure and hence is strategically risky. Based on their private information, agents { who have heterogeneous investment incentives - form expectations or "sentiments" about the project's outcome. We...
