Increasingly Mean-Seeking Utility Functions and N-Asset Portfolios
Abstract
The literature exhibits a dearth of comparative static results for n-asset portfolios. This paper shows a necessary and sufficient condition on utility functions for an increase in initial wealth never to decrease expected per-dollar final wealth in optimal n-asset portfolios. For the resulting utility function class the literature provides a measure of relative risk of portfolios; it is shown here that relative risk never decreases in optimal n-asset portfolios as initial wealth rises.
