Bestehende SRI-Ansätze haben Umwelt-, Sozial- und Governancekriterien (ESG Kriterien) als weitere Dimension in die Portfolioauswahl einbezogen; diese Ansätze konzentrieren sich allerdings auf klassische Investoren und berücksichtigen nicht spezifische Aspekte von Versicherungsunternehmen. In unserem Beitrag betrachten wir das Problem der Aktienportfolioselektion von Lebensversicherungsunternehmen. Neben dem Aktienrisiko berücksichtigt unser Modell auch andere wichtige Marktrisikokategorien von Versicherern, nämlich das Zinsrisiko und das Kreditrisiko. In Übereinstimmung mit den üblichen Standards in der Solvabilitätsregulierung messen wir das Risiko anhand der Solvenzquote, d.h. anhand des Verhältnisses zwischen dem marktbasierten Eigenkapital des Versicherers und den Solvenzkapitalanforderungen aller modellierten Risikokategorien. Hierauf aufbauend verwenden wir eine Modifikation der Portfolioselektionstheorie nach Markowitz, indem wir die Solvenzquote als Maß für das Abwärtsrisiko nutzen, um mögliche optimale Portfolios in einer dreidimensionalen (Risiko, Rendite und ESG) Kapitalallokationsebene zu identifizieren. Wir stellen fest, dass bei einer gegebenen Solvenzquote Aktienportfolios mit einem moderaten ESG-Niveau zu einer höheren erwarteten Rendite führen können als solche mit einem niedrigen ESG-Niveau. Ein sehr ehrgeiziges ESG-Niveau verringert jedoch die erwartete Rendite. Aufgrund der Besonderheiten in ihrem Geschäftsmodell können die Auswirkungen des ESG-Niveaus auf die erwartete Rendite von Lebensversicherern erheblich von den entsprechenden Auswirkungen für klassische Investoren abweichen.","PeriodicalId":39247,"journal":{"name":"Zeitschrift für die gesamte Versicherungswissenschaft","volume":"201 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136361896","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
