Zuweilen wird die Meinung vertreten, dass es Investoren um jeden Preis vermeiden sollten, Steuern zu zahlen. Im Rahmen eines einfachen Portfoliomodells mit Steuern wird untersucht, ob Steuervermeidung tatsächlich auf μ-σ2-effiziente Lösungen führt. Für vier verschiedene Konzepte der...

In der Literatur zur Steuerwirkung des CAPM wurde bisher unterstellt, dass die Steuerzahlungen nicht an die Marktteilnehmer zurückverteilt werden. Diese Annahme ist unrealistisch. Wir lassen sie in diesem Modell fallen. Aus der allgemeinen Gleichgewichtstheorie ist bekannt, dass bei einem...

In this paper we consider firms having pension and other non-tradeable liabilities and we ask whether the methods of discounted cash flow (DCF) can be used for evaluation of the company. This question was so far not discussed in the literature systematically. We show how balance sheet are to be...
