"Eine der Funktionsbedingungen für Kassenwettbewerb ist, dass Risikoselektion unterbunden wird. Denn Gegenstand des Kassenwettbewerbs sollen nicht bestimmte Merkmale von Versicherten sein (z.B. der Gesundheitszustand), vielmehr sollen die Anreize zur Verbesserung der Qualität und Effizienz der medizinischen Versorgung verstärkt werden. In einem wettbewerblichen Krankenversicherungssystem mit Risikoselektion werden die Interessen schlechter Risiken unzureichend berücksichtigt. Risikoselektion in der gesetzlichen Krankenversicherung (GKV) soll durch den Risikostrukturausgleich (RSA) verhindert werden. Seine Ausgestaltung muss bisher als unzureichend bezeichnet werden. Die Versichertenmerkmale Einkommen und Morbidität werden nicht hinreichend ausgeglichen. Theoretisch bestehen für die Krankenkassen also deutliche Anreize, Risikoselektion zu betreiben, was sich in der Empirie durch zahlreiche Beispiele belegen lässt." (Autorenreferat)... view less

"One of the requirements for the good functioning of competition among sickness funds is the absence of risk selection. Selection by funds has adverse effects which counter the positive effects of competition, to name the improvement of quality and efficiency of medical care. The interests of insured persons with high risks are inadequately accounted for in a competitive health insurance market with risk selection. Risk selection in the German statutory health insurance market is to be preserved by a system of risk equalization payments among German Statutory Sickness Funds. This risk compensation scheme is so far incomplete. The compensation for morbidity and income is inadequate. In theory, there are strong incentives for the sickness funds to select good risks, which can be affirmed by many examples." (author's abstract)... view less
