Abstract Much of the evidence supporting the Ellsberg's paradox comes from experiments on individual choice and judgement. In this study, we address the issue whether, in market experiments, there is a tendency for anomalous behaviour to disappear or to be reduced as a consequence of market...

Much of the evidence supporting the EllsbergÕs paradox comes from experiments on individual choice and judgement.In this study, we address the issue whether, in market experiments, there is a tendency for anomalous behaviour to disappear or to be reduced as a consequence of market experience...

In a series of experiments the interactions among individual attitudes towards risk and uncertainty, the sign of the outcome domain, and the way uncertainty is represented are tested. This is done in a unified framework, eliciting individual values by means of a second price auction. Results...

In a laboratory experiment we test the hypothesis that consumers' valuation of insurance is sensitive to the amount of information available on the probability of a potential loss. In order to test this hypothesis we simulate a market in which we elicit individuals' willingness to pay to insure...

In this work we use data from two sets of midterm exams and question-by-question evaluations of confidence levels and construct different indicators in order to study predictive ability and overconfidence. Our results show that (1) there is a significant evidence of a good ability of...

In the literature of happiness economics individual subjective utility is measured by directly asking individuals to self-assess their level of utility, usually on a numerical scale, using various terms such as happiness, life satisfaction and well-being, most of the times taking for granted...

There is a large theoretical literature in both economics and psychology on decision making under ambiguity (as distinct from risk) and many preference functionals proposed in this literature for describing behaviour in such contexts. However, the empirical literature is scarce and largely...

This paper presents the results of two experiments designed to test violations of Subjective Expected Utility Theory (SEUT) within a sample of Italian trade union delegates and leaders. Subjects priced risky and ambiguous prospects in the domain of gains. Risky prospects were based on games of...
