This is the theory of Milton Friedman and Leonard Savage postulating that the curvature of an individual's utility function differs based upon the amount of wealth the individual has. The utility function is concave to the left of the origin and convex to the right. We propose a parametric form of utility consistent with Markowitz’s (1952) hypotheses as a useful model to consider. Markowitz The Markowitz model is based on several assumptions concerning the behavior of investors: 1. Utility Analysis and Group Behavior: An Empirical Study Friedman–Savage utility function - Wikipedia Critiques to expected utility theory | Policonomics If an investor’s utility function is expressed as U=E(r)−12Aσ2 and the measure for risk aversion has a value of −2, the risk-seeking investor is most likely to choose: A. In summary, in the presence of a risk-free asset the efficient frontier becomes a straight line known as the capital market line. It's important to understand the pitfalls of using a Markowitz analysis, particularly the lack of robustness with respect to errors in estimating certain parameters. Financial Markowitz Portfolio Optimization (Bonds, Stocks, Commodities), including classical Efficient Frontier, Utility Function etc. utility functions, there is not a direct equivalence between expected utility max-imization and mean-variance criteria. Explanation of the Allais paradox and the preference of many for multiple prize lottery tickets provide a rationale for why a model of agent's choice under uncertainty should embody the assumption that they distort probabilities.
