Fünf Fragen (und Antworten) zur Gesundheitsökonomik

Peter Zweifel

Zusammenfassung

In diesem Übersichtsartikel beschreibt Peter Zweifel die Entwicklung des Fachgebiets „Gesundheitsökonomik“ an Hand von Antworten auf fünf Fragen: Ist das Gut „Gesundheit“ wirklich anders als alle andern? Geht es zentral um die „Kostenexplosion“? Was ist die Bedeutung des moralischen Risikos im Vergleich zur adversen Selektion auf Märkten für Krankenversicherung mit Wettbewerb? Wie bedeutsam ist die anbieterinduzierte Nachfrage? Und schließlich, gibt es eine Begründung für den außerordentlich hohen Grad der Regulierung im Gesundheitswesen? Die Antworten sind solide in der Mikroökonomik verankert; sie sollten jedoch verdeutlichen, dass Ökonomen mit Interesse am Gesundheitsverhalten und am Gesundheitswesen der Karikatur des „erbsenzählenden Elefanten im Porzellanladen“ (Gbadebo und Reinhardt 2001) überhaupt nicht entsprechen.

Abstract

In this survey, Peter Zweifel describes the development of Health Economics as a discipline using five questions to be answered: Is health different from all other goods? Is the “cost explosion” the core issue? What is the relative importance of moral hazard and adverse selection in competitive markets for health insurance? What is the relevance of supplier-induced demand? And finally, is there an economic justification for the very high degree of regulation in health care? While the answers are soundly grounded in microeconomic theory, they hopefully show that economists interested in health and health care are far from the caricature of penny-pinching “elephants in a porcelain shop” (Gbadebo and Reinhardt 2001).
