We study in an experiment whether humans prefer to depend on decisions of other humans (social uncertainty) or states … other humans. This is the first experiment that studies social uncertainty that does not derive from a strategic situation …

We implement an experiment to elicit subjects’ ambiguity attitudes in the spirit of Ellsberg’s three-color urn. The …

choice between risky and ambiguous Ellsberg urns, we let them choose between a safe option and a risky lottery, whose risk is …, subjects can reduce or even eliminate the ambiguity and turn the decision situation into one of risk. Under the assumption that … request more information. Moreover, we investigate whether the relation between attitudes towards risk and ambiguity is linked …

We report a portfolio-choice experiment that enables us to estimate parametric models of ambiguity aversion at the … specification includes two parameters: one for ambiguity attitudes and another for risk attitudes. We also estimate a three …

experiment where the decision maker draws twice with replacement in the typical Ellsberg two-color urns, but with a different … utility all predict unequivocally that risk-averse decision makers (DMs) will avoid the 50 - 50 urn that exhibits the highest … risk conceivable, while risk-seeking DMs do the opposite. However, we observe a substantial number of violations in the …

previous studies that found a negative relation between cognitive ability and risk aversion into perspective and in particular … show that cognitive ability is related to noisy behavior rather than risk preferences.
