Diese Arbeit untersucht die Auswirkungen einer Erhöhung der Lebensarbeitszeit für den Beitragssatz einer umlagefinanzierten Rentenversicherung. Dabei werden die von der längeren Lebensarbeitszeit betroffenen Personen durch versicherungsmathematische Zuschläge entschädigt. Es wird gezeigt,...

We study the effects of 'balance billing', i.e., allowing physicians to charge a fee from patients in addition to the fee paid by Medicare. First, we show that on pure efficiency grounds the optimal Medicare fee under balance billing is zero. An active Medicare policy thus can only be justified...

This study investigates hospitals’ dynamic incentives to select patients when hospitals are remunerated according to a prospective payment system of the DRG type. Given that prices typically reflect past average costs, we use a discrete-time dynamic framework. Patients differ in severity...

This paper studies how society votes on the payroll taxes of a basic income and a social health insurance scheme. Individuals differ along the two most important dimensions when it comes to the design of the two welfare schemes, namely, income and risk. Even though the introduction of a basic...

In 2009 the German central health fund was implemented. It was the result of a political compromise. One political party intended to equalise the risk structure among 130 different health care funds, and the other wanted to intensify competition and to improve efficiency among the different...

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 examines the trade-off between risk allocation and quality supply for an insurance monopolist when individuals face two kinds of risk related to health. First, they may suffer an ordinary monetary loss. Second, they are subject to uncertain premiums because their type may change. We...

We analyze the effects of a permanent increase in life expectancy and of a permanent decline in the rate of population growth on intergenerational redistribution in a pay-as-you-go pension system with a constant contribution or constant replacement rate. We show that under these policies both...

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...
