We analyze competitive credit markets with asymmetric information in which borrowers seek financing for either positive or negative net present value projects. The striking result is that there always exists an equilibrium where investment is efficient, while competitive lenders make strictly...

We consider a model of competitive insurance markets under asymmetric information with ambiguity-averse agents who maximize their maxmin expected utility. The interaction between asymmetric information and ambiguity aversion gives rise to some interesting results. First, for some parameter...

We consider a model of competitive insurance markets involving both asymmetric information and ambiguity about the accident probability. We show that there can exist a full-insurance pooling equilibrium. We also present an example where an increase in ambiguity leads to a strict Pareto...

This paper revisits the problem of adverse selection in the insurance market of Rothschild and Stiglitz. We propose a simple extension of the game-theoretic structure in Hellwig under which Nash-type strategic interaction between the informed customers and the uninformed fi rms results always in...

In this paper, we provide a unified framework for analyzing competitive markets with adverse selection. The key feature of our model is that whether the suppliers of the contracts (uninformed) are committed to the contracts they offer or not is determined endogenously. Because of the endogeneity...
