One of the main features of health insurance is moral hazard, as defined by Pauly (1968); people face incentives for excess utilization of medical care since they do not pay the full marginal cost for provision. To mitigate the moral hazard problem, a coinsurance can be included in the insurance...

Given heterogeneity in incomes and health risks, with asymmetric information in the latter, preferences over the public-private mix in health insurance and care are derived. Results concerning crowding-out in the presence of adverse selection are established. For low-risk individuals,...

We study a health-insurance market where individuals are o.ered coverage against both medical expenditures and losses in income. Individuals vary in their level of innate ability. If there is private information about the probability of illness and an individual’s innate ability is su.ciently...

Several empirical studies provide evidence that their actual health state affects people's attitudes towards health and medical care in hypothetical health states. In the tradition of behavioural economics this paper considers the actual health state as a point of reference and builds a model...

A common approach to avoid risk selection in health insurance markets is to define and enforce a community-rated basic benefit package. The market for complementary insurance is usually completely separate from the market for basic health insurance. In Switzerland, however, the basic benefit...

In the absence of a perfect risk adjustment scheme, reimbursing health insurers' costs can reduce risk selection in community-rated health insurance markets. In this paper, we develop a model in which insurers determine the cost efficiency of health care and have incentives for risk selection....

This paper analyses possible options how to improve the risk adjustment of the health insurance system in the Czech Republic. Out of possible options it argues for including Pharmaceutical Cost Groups (PCGs) as additional risk factors since it is an improvement that can be implemented almost...
