In this paper it is shown that the combination of mental accounting and loss aversion can fundamentally changes people's way of evaluating risky alternatives. The observation is applied in a market setting: Parimutuel betting markets. In parimutuel betting markets it has been found that for...

This paper studies a class of robust mean-variance portfolio selection problems with state-dependent risk aversion. Model uncertainty, in the sense of considering alternative dominated models, is introduced to the problem to reflect the investor's ambiguity aversion. To characterize the robust...

Measuring risk aversion is sensitive to assumptions about the wealth in subjects' utility functions. Data from the same subjects in low- and high-stake lottery decisions allow estimating the wealth in a pre-specified one-parameter utility function simultaneously with risk aversion. This paper...

A game-theoretic framework that allows for explicitly randomized strategies is used to study the effect of ambiguity aversion on equilibrium outcomes. The notions of "independent strategies" as well as of "common priors" are amended to render them applicable to games in which players lack...

Although risk aversion has been used in economic models for over 275 years, the past few decades have shown how higher order risk attitudes are also quite important. A behavioral approach to defining such risk attitudes was developed by Eeckhoudt and Schlesinger (2006), based upon simple lottery...

This paper analyzes, for S-shaped value functions, the relations between loss aversion and perceptional risk aversion (i.e. computed with the perceived probability weights) in Cumulative Prospect Theory. We show that perceptional risk aversion for mixed sign lotteries is equivalent to weak loss...

In this article, a simple paper-and-pencil experiment, based on lottery bonds, shows that financial decisions taken by participants are inconsistent with the traditional view of economic agents as risk averse expected utility maximizers. First, our results cast doubt on the relevance of variance...

Parametric and non-parametric risk aversion is often elicited through binary lotteries. Basing ourselves on recent evidence of the higher than theorized importance of skewness in decision making, we highlight in this paper that skewness might bias the result of risk aversion elicitation in two...
