This paper studies general health insurance markets. It proposes an ex post risk adjustment scheme that discourages risk selection and promotes efficient competition. Under the proposed risk adjustment scheme, the regulator engages in transfers that are conditional on the ex post profits of...

Not only does economic theory predict high-risk individuals to be more likely to purchase insurance, but insurance coverage is also thought to crowd out precautionary activities. In spite of stark theoretical predictions, there is conflicting empirical evidence on adverse selection, and evidence...

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,...

We investigate the presence of moral hazard and advantageous or adverse selection in a market for supplementary health insurance. For this we specify and estimate dynamic models for health insurance decisions and health care utilization. Estimates of the health care utilization models indicate...

The identification of information problems in different markets is challenging issue in the economic literature. In this paper, we study the identification of moral hazard from adverse selection and learning within the context of a multi-period dynamic model. We extend the model of Abbring et...

Given adverse selection, durable goods that trade infrequently depreciate quickly. Consistent with this prediction I find an inverse relationship between depreciation and trading volume for less reliable brands of used business aircraft. Additionally, recent theoretical analyses suggest that...
