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...

We conducted a set of experiments to compare the effect of ambiguity in single person decisions and games. Our results suggest that ambiguity has a bigger impact in games than in ball and urn problems. We find that ambiguity has the opposite effect in games of strategic substitutes and...

This paper presents a nonparametric approach to classification of data from lottery experiments. Using very basic mathematical tools the paper endeavors to answer the questions: How to determine the "average" subject in a group? How to find a subject presenting the most similar behavior to a...

I experimentally examine whether feedback about others' choices provides an anchor for decision-making under ambiguity. In a between-subjects design I vary whether subjects learn choices made individually by a "peer" in a first part when facing the same task a second time, and whether prospects...

This paper theoretically and experimentally studies decision-making in risky and social environments. We explore the interdependence of individual risk attitudes and social preferences in form of inequality aversion as two decisive behavioral determinants in such contexts. Our model and the data...
