We study the existence of a profitable unemployment insurance market in a dynamic economy with adverse selection rooting in information on future job losses. The new feature of the model is that the insurer and workers interact repeatedly. Repeated interactions make it possible to threaten...

In a continuous-time setting, we study the design of a dynamic contract between a government and a private entity, wherein the latter commits to pay the government in return for the exclusive right to sell a service by operating a public facility. Private revenues are modelled as depending on...

I prove an efficiency result for repeated games with imperfect public monitoring in which one player's utility is privately known and evolves according to a Markov process. Under certain assumptions, patient players can attain approximately efficient payoffs in equilibrium. The public signal...

The paper studies, in a repeated interaction setting, how the presence of cooperative agents in a heterogeneous community organized in groups affects efficiency and group stability. The paper expands on existing literature by assuming that each type can profitably mimic other types. It is shown...

In a contestable market the possibility of "hit-and-run" entry prevents the price from rising above average cost. A contestable natural monopoly earns zero profits despite economies of scale. We show that informational imperfections can also result in a single firm serving the entire market with...

This work takes a closer look on the predominant assumption in usual lemon market models of having finitely many or even only two different levels of quality. We model a situation which is close to the classical monopolistic setting but admits an interval of possible quality values....

This paper studies the incentive of a long run seller to disclose past offers when trading with a sequence of short-run buyers. Compared with the models of mandatory disclosure or mandatory non-disclosure, there is a new set of equilibria generated by allowing flexibility in the disclosure...

This paper studies asset markets where buyers of assets do not inherit private information from previous owners and must learn asset quality over time. Imperfect information transmission reduces asymmetric information, but also reduces the trading volume, prices and efficiency. This result is...
