In this paper, equilibrium of the life/medical insurance market is analyzed under conditions where insurers demands that an insurant undergo genetic testing, on the assumption that the Human Genome Project will allow direct insight into the precise manner of operation of individual genes. Also,...

This study is based on the assumption that in future, genetic testing will create a situation where people can tell whether they are disposed to certain diseases including cancer, but utilization of such genetic testing is banned for the purposes of medical examination of insurants. What, then,...

In this paper we propose a simple method of characterizing countervailing incentives in adverse selection problems. The key element in our characterization consists of analyzing properties of the full information problem. This allows solving the principal problem without using optimal control...

We study a nonexclusive insurance market with adverse selection in which insurers compete through simple contract offers. Multiple contracting endogenously emerges in equilibrium. Different layers of coverage are priced fairly according to the types of insurees who purchase them, giving rise to...

We analyze markets where insurers are better informed about risk than consumers. We show that even competitive markets may result in insufficient information revelation and inefficient insurance coverage. This explains why certain risky consumers remain uninsured and why certain market segments...

We examine equilibria in competitive insurance markets when individuals take unobservable labor supply decisions. Precautionary labor motives intro-duce countervailing incentives in the insurance market, and equilibria with positive profits can occur even in the standard case in which...

We examine equilibria in competitive insurance markets with adverse selection when wealth differences arise endogenously from unobservable savings or labor supply decisions. The endogeneity of wealth implies that high risk individuals may ceteris paribus exhibit the lower marginal willingness to...

We examine equilibria in the sense of Rothschild and Stiglitz (1976) in competitive insurance markets when individuals take unobservable labor supply decisions. Precautionary labor motives introduce countervailing incentives in the insurance market, and imperfect type separation can occur in the...

We provide an experimental analysis of competitive insurance markets with adverse selection. Our parameterized version of the lemons' model (Akerlof 1970) in the insurance context predicts total crowding out of low-risks when insurers offer a single full insurance contract. The therapy proposed...
