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...

When hiring an adviser (he), a policy maker (she) often faces the problem that she has incomplete information about his preferences. Some advisers are good, in the sense that their preferences are closely aligned to the policy maker's preferences, and some advisers are bad. Recently, some...

We investigate the nature of the adverse selection problem in a market for adurable goodwhere trading and entry of new buyers and sellers takes place in continuoustime. In thecontinuous time model equilibria with properties that are qualitativelydifferent from thestatic equilibria, emerge....

Banks provide risky loans to firms which have superior information regarding the quality of their projects. Due to asymmetric information the banks face the risk of adverse selection. Credit Value-at-Risk (CVaR) regulation counters the problem of low quality, i.e. high risk, loans and therefore...

We take a dynamic perspective on insurance markets under adverseselection and study a generalized Rothschildand Stiglitz model where agents may differ with respect to theaccidental probability and their expenditure levels incase an accident occurs. We investigate the nature of dynamicinsurance...

I present a model in which individuals compete for a prize by choosing to apply or not. Abilities are private information and in attempt to select the best candidate, the committee compares applicants with an imperfect technology. The choice of application cost, size of the prize and use of...

This paper studies the design of tax systems that implement a planner's second-best allocation in a market economy. An example shows that the widely used Mirrleesian (1976) tax system cannot implement all incentive-compatible allocations. Hammond's (1979) "principle of taxation" proves that any...
