We study the impact of frictions on the prevalence of systemic crises. Agents privately learn about a fixed payoff parameter, and repeatedly adjust their investments while facing transaction costs in a dynamic global game. The model has a rich structure of externalities: payoffs may depend on...

We present a family of tractable dynamic global games and its applications. Agents privately learn about a fixed fundamental, and repeatedly adjust their investments while facing frictions. The game exhibits many externalities: payoffs may depend on the volume of investment, on its volatility,...

We present a two-stage coordination game in which early choices of experts with special interests are observed by followers who move in the second stage. We show that the equilibrium outcome is biased toward the experts' interests even though followers know the distribution of expert interests...

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 (ir)reversibility of early actions plays an important role in the...

We study a learning process in which subjects extrapolate from their experience of similar past strategic situations to the current decision problem. When applied to coordination games, this learning process leads to contagion of behavior from problems with extreme payoffs and unique equilibria...

It is well documented that the possibility of punishing free-riders increases contributions in one-shot public good games. I demonstrate theoretically that minimal punishment commitments (perhaps provided by anger) may lead to high contribution levels. Thus, almost selfish players may behave as...

We build a dynamic global game in which players repeatedly face a similar coordination problem. By choosing a risky action (invest) instead of an outside option (not invest), players risk instantaneous losses as well as payoffs from future stages, in which they cannot participate if they go...

We study coordination failures in many simultaneously occurring coordination problems called projects. Players encounter one of these projects, but have an outside option to search for another of the projects. Drawing on the global games approach, we show that such a mobile game has a unique...

We provide a set of new models of three different processes by which political parties nominate candidates for a general election: nominations by party leaders, nominations by a vote of party members, and nominations by a spending competition among potential candidates. We show that more extreme...
