Asset Demand: A Simple Dual Approach

Author

  • Appelbaum, Elie

Abstract

This paper provides a simple framework for obtaining asset demand using indirect utility functions. Assuming expected utility maximization, we show that assets are held according to their mean returns' proportional marginal utility. We also show that an asset's equilibrium equity premium is given by the ratio of the indirect utility function's mean and standard deviation elasticities. Furthermore, we show that we can extend these results to a non-expected utility framework.
