It is shown how to test revealed preference data on choices under uncertainty for consistency with first and second order stochastic dominance (FSD or SSD). The axiom derived for SSD is a necessary and sufficient condition for risk aversion. If an investor is risk averse, stochastic dominance...

This paper presents the results of an experiment that demonstrates that personality may have a significant impact on economic decision making under uncertainty. This impact is indirect since differences in personality characteristics lead decision makers to seek different types of information...

This paper is motivated by the current debate on limiting auditor liability. In a laboratory experiment, the effect of limited versus unlimited liability on behavior under risk and ambiguity is investigated for risks involving small probabilities. The amount of liability is manipulated in such a...

In this paper, we report the results of experiments designed to test whether individuals and groups abide by the axioms of monotonicity, with respect to first-order stochastic dominance and Bayesian updating, when making decisions in the face of risk. The results indicate a significant number of...

Decision and risk analysts have considerable discretion in designing procedures for eliciting subjective probabilities. One popular approach is to specify a particular set of exclusive and exhaustive events for which the assessor provides subjective probabilities. We show that assessed...

Two distinct interpretations of ambiguity attitudes have been proposed, namely, weighting the multiple priors pessimistically and exhibiting preference over different sources of uncertainty. This study examines the links among attitudes towards three sources of uncertainty including ambiguity...

We experimentally study agents’ preferences for ambiguity resolution in dynamic environments. We theoretically demonstrate that the three most popular recursive models of ambiguity aversion make different predictions regarding agents’ preferences for the timing and graduality of ambiguity...

Using a revealed preference approach, we conduct an experiment where subjects make choices from linear convex budgets in the domain of risk. We find that many individuals prefer mixtures of lotteries in ways that systematically rule out expected utility behavior. We explore the extent to which...

Incentivized experiments in which individuals receive monetary rewards according to the outcomes of their decisions are regarded as the gold standard for preference elicitation in experimental economics. These task-related real payments are considered necessary to reveal subjects' \true...
