Portfolio Behaviour and Asset Pricing in a Characteristics Framework.

This paper argues that the characteristics model of demand provides a unifying framework for examining preference-based asset portfolio behavior and asset pricing. In particular, the author shows that it encompasses a number of very familiar models of portfolio behavior and asset pricing: the state-preference model, the parameter-preference model, the capital asset pricing model, and the intertemporal capital asset pricing model.
