There is a general presumption that competition is a good thing. In this paper we show that competition in the insurance markets can be bad when there is adverse selection; Using the dual theory of choice under risk, we are able to fully characterize both the competitive and the monopoly market...

We develop a methodology to sign output distortions in the random participation framework. We apply our method to monopoly nonlinear pricing problem, to the regulatory monopoly problem and mainly to the optimal income tax problem. In the latter framework, individuals are heterogeneous across two...
