people's preferences are affected by ambiguity. Health economic analyses generally ignore ambiguity preferences and assume … that they are the same as preferences under risk. We show how health preferences can be measured under ambiguity and we … compare them with health preferences under risk. We assume a general ambiguity model that includes many of the ambiguity …

Individuals exhibit a randomization preference if they prefer random mixtures of two bets to each of the involved bets. Such preferences provide the foundation of various models of uncertainty aversion. However, it has to our knowledge not been empirically investigated whether uncertainty-averse...

To make predictions with theories, usually we assume an individual's characteristics such as uncertainty preferences to be stable over time. In this paper, we analyze the stability of ambiguity preferences experimentally. We repeatedly elicit ambiguity attitudes towards multiple 3-color Ellsberg...

Recently proposed models of risky choice imply systematic violations of transitivity of preference. Five studies explored whether people show patterns of intransitivity predicted by four descriptive models. To distinguish trueʺ violations from those produced by error,ʺ a model was fit in which...

Several models of choice under uncertainty imply systematic violations of transitivity of preference. Our experiments explored whether people show patterns of intransitivity predicted by these models. To distinguish "true" violations from those produced by "error," a model was fit in which each...
