Aufbauend auf einem klassischen Finanzmarktmodell behandeln wir drei Modellvarianten, die jeweils einen anderen Ansatz der (heterogenen) Erwartungsbildung von Investoren über künftige Wertpapierpreise in den Vordergrund der Betrachtungen rücken: das Konzept der konsistenten Erwartungen, das...

We compare the performance of the characteristics-based parametric portfolio approach introduced by Brandt, Santa Clara and Valkanov (RFS 2009) with standard optimal portfolio investments on the basis of S&P-500 stocks. We establish that the characteristics-based parametric portfolio approach...

We provide examples of pitfalls for parametric portfolio policies as introduced by Brandt, Santa Clara and Valkanov. For the leading case of constant relative risk aversion (CRRA) strong assumptions on the properties of the returns, the variables used to implement the parametric portfolio policy...

We extend the d cifically we analyse constant absolute and constant relative risk aversion, provide conditionsfor the existence of equilibrium, and evaluate equilibrium prices at US-data. We find that constant absolute risk aversion works particularly well at moderate levels of risk aversion. In...
