We provide examples of pitfalls for parametric portfolio policies as introduced by Brandt, Santa Clara and Valkanov (RFS 2009). 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...

This paper derives conditions under which the well-known decomposition of unconditional expected utility into marginal probabilities and conditional expected utility generalizes to Cumulative Prospect Theory, as well as updating rules for probability weighting functions. The results are, for...
