Utility Maximization, Risk Aversion, and Stochastic Dominance
Consider an investor trading dynamically to maximize expected utility from terminal wealth. Our aim is to study the dependence between her risk aversion and the distribution of the optimal terminal payoff. Economic intuition suggests that high risk aversion leads to a rather concentrated distribution, whereas lower risk aversion results in a higher average payoff at the expense of a more widesp...
متن کاملRisk Aversion Asymptotics for Power Utility Maximization
We consider the economic problem of optimal consumption and investment with power utility. We study the optimal strategy as the relative risk aversion tends to in nity or to one. The convergence of the optimal consumption is obtained for general semimartingale models while the convergence of the optimal trading strategy is obtained for continuous models. The limits are related to exponential an...
متن کاملStochastic Dominance and Absolute Risk Aversion
In this paper we propose the inÞmum of the Arrow-Pratt index of absolute risk aversion as a measure of global risk aversion of a utility function. We then show that, for any given arbitrary pair of distributions, there exists a threshold level of global risk aversion such that all increasing concave utility functions with at least as much global risk aversion would rank the two distributions in...
متن کاملUtility maximization under increasing risk aversion in one-period models
It has been shown at different levels of generality that under increasing risk aversion utility indifference sell prices of a contingent claim converge to the super-replication price and the shortfalls of utility maximizing hedging portfolios starting from the superreplication price tend to zero in L1. In this paper we give an example of a one-period financial model with bounded prices where ut...
متن کاملRisk Aversion and Stochastic Dominance: A Revealed Preference Approach
Theoretically, given a choice over two risky assets with equivalent expected returns, a risk averse expected utility maximizer should choose the second-order stochastically dominant asset. We develop a theoretical framework that allows for decision error, which should decrease in risk aversion. We conduct an experiment using a risk preference elicitation mechanism to identify risk averse indivi...
