We show that if an agent is uncertain about the precise form of his utility function, his actual relative risk aversion may depend on wealth even if he knows his utility function lies in the class of constant relative risk aversion (CRRA) utility functions. We illustrate the consequences of this...

We determine the importance of long-term and short-term components of state variables for asset allocation decisions. The long-term and short-term decompositions are performed using a variety of filtering techniques. We allow for a flexible semiparametric form of the dependence of asset...
