A Survey Data Response to the Teaching of Utility Curves and Risk Aversion

Abstract

In many finance and economics courses as well as in practice, the concept of risk aversion is reduced to the standard deviation of returns, whereby risk-averse investors prefer to minimize their portfolios’ standard deviations. In reality, the concept of risk aversion is richer and more interesting than this, and can easily be conveyed through theoretical or applied examples. The authors offer an example of a 2-asset choice problem in which risk-averse investors ought to prefer the asset with not only a higher standard deviation but also a lower expected return. A corresponding survey of 131 respondents confirmed this preference.
