This paper focuses on information acquisition and individual decision making in ambiguous situations and presents a novel experimental design which may help to tackle open questions from a fresh perspective. Instead of giving subjects the choice between risky and ambiguous Ellsberg urns, we let...

This paper experimentally investigates individual information acquisition and decisions in ambiguous situations in which the degree of ambiguity can endogenously and individually be decreased by the subjects. In particular, I analyze how risk aversion, ambiguity attitude and personality traits...

In this study we measure higher-order risk preferences and their consistency. We explore the role of country differences, the variation of stakes, and the framing of lotteries. We observe a robust dichotomous pattern of choice behavior in China, in the USA and in Germany. A large majority of...

We study higher-order risk preferences, i.e. prudence and temperance, next to risk aversion in social settings. Previous experimental studies have shown that higher-order risk preferences affect the choices of individuals deciding privately on lotteries that only affect their own pay-off. Yet,...

Recent health policy reforms try to increase consumer choice. We use a laboratory experiment to analyze consumers' tastes in typical contract attributes of health insurances and to investigate their relationship with individual risk preferences. First, subjects make consecutive insurance choices...

Decision makers often take risky decisions on the behalf of others rather than for themselves. Competing theoretical models predict both, higher as well as lower levels of risk aversion when taking risk for others, and the experimental evidence is mixed. In our within-subject design, money...

We study risk aversion and prudence in medical treatment decisions. In a laboratory experiment, we investigate the frequency and intensity of second- and third-order risk preferences, as well as the effect of the medical decision context. Risk preferences are assessed through treatment...

In this study I analyze how lottery framing and lottery display type affect the degree of higher-order risk preferences. I explore differences by comparing reduced and compound lottery framing, and by comparing lotteries in an urn-style and in a spinner-style display format. Overall, my findings...
