During the 1990s, the social health insurance schemes of Germany, the Netherlands, Switzerland, Belgium and Israel were significantly reformed by the introduction of freedom of choice (open enrolment) of health insurer. This was introduced alongside a system of risk adjustment to compensate...

In the search for greater efficiency and cost-containment, many health systems have introduced the practice of medical care providers operating under a fixed budget, often referred to as the capitation or fundholding contract. Although the capitation contract seems equitable at first glance, the...

This note comments on the application of results from the theory of fair compensation to risk adjustment. It argues that the main flaw of such application lies in the consideration of health plans merely as administrative social agents, through which money flows from a central fund to providers...

The empirical effect of health status on private insurance ownership is a mixture of the effect of health on the demand for insurance (subjected to adverse selection) and its effect on the insurer's underwriting practice (subjected to risk-selection). Using bivariate partial observability probit...

The imperfect risk adjustment of prospective payment for hospitals may have dramatic consequences on equity. If the hospital is able to distinguish subgroups of patients with different expected costs within a group for which the risk-adjusted payment per admission is the same, it is likely to...

The nature of the private–public mix in health insurance and in health care is a major issue in most health systems.

Risk adjustment of the allocated health budget to health plans plays a major role in the functioning of competitive social health insurance systems. Whenever the risk adjusted allocation is below the expected marginal cost of care for a given person, incentives for risk selection arise. Since...

From the mid-1990s several countries have introduced elements of regulated competition in healthcare. The aim of this paper is to identify the most important preconditions for achieving efficiency and affordability under regulated competition in healthcare, and to indicate to what extent these...

The main objective of risk adjustment in systems of regulated competition on health insurance markets is the removal of incentives for undesirable risk selection. We introduce a simple conceptual framework to clarify how the definition of "acceptable costs" and the distinction between legitimate...
