Abstract

Ziel dieser Arbeit ist es, in die ökonomische Analyse des Versicherungsbetrugs einzuführen und einige grundlegende Determinanten für vertragswidriges Verhalten von Versicherungsnehmern aufzuzeigen. Dazu werden zunächst die strategischen Entscheidungsprobleme von Versicherungsnehmern und Versicherern eingehend analysiert und optimales Verhalten unter realitätsnahen Annahmen hergeleitet, sowie Ansatzpunkte für die Betrugsbekämpfung aufgezeigt. Beispielhaft werden dazu die Auswirkungen von Betrugserkennungssystemen oder die konsequente Anzeige entdeckter Betrüger auf die Bekämpfung von Versicherungsbetrug näher untersucht. Es zeigt sich, dass beide Ansatzpunkte erheblichen Einfluss auf die Kosten des Versicherungsbetrugs haben können. Ein häufig geäußerter Kritikpunkt an solchen Analysen ist, dass ethische Bedenken der Versicherungsnehmer meist unberücksichtigt bleiben. Die Einbeziehung von ethischen Bedenken führt aber nicht zwangsläufig zu einer niedrigeren Betrugshäufigkeit. Abschließend wird der Frage nachgegangen, inwieweit Versicherungsbetrug auf versicherungsspezifische Faktoren zurückzuführen ist und wie bzw. in welchem Umfang Versicherer Einfluss auf die ethische Bewertung des Versicherungsbetrugs durch Versicherungsnehmer nehmen können.
