Using an experiment with incentivized decisions of groups in the economics laboratory, I investigate the effect of group diversity on group risk taking. I measure econometrically the effects of various aspects of subjects' diversity: nationality, language, university degree and gender. I find...

Low self-control is considered a fundamental cause of crime. The aim of our study is to provide causal evidence on the link between self-control and criminal behavior. We test whether individuals with lower self-control behave in a more antisocial manner and are less risk-averse and thus are,...

This paper reports on an experiment designed to examine the effects of small-scale changes in wealth on risk attitudes. We find that the money given prior to risky choices does not induce a change of subjects' risk preferences. This result supports a key assumption in a recent literature over...

We investigate experimentally the effect of consultation (unincentivized advice) on choices under risk in an incentivized investment task. We compare these choices to two benchmark treatments: one with isolated individual choices, and a second with group choice after communication. Our...

We report an experiment examining risk taking and information aggregation in groups. Group members come to the table with an individual preference for a choice under risk, based on privately received information, and can share this information with fellow group members. They then make a decision...

We examine confidence in own absolute performance using two elicitation procedures: selfreported (non-incentivised) confidence and an incentivised procedure that elicits the certainty equivalent of a bet based on performance. The former procedure reproduces the "hard-easy effect" (overconfidence...

We use an experimental lottery choice task and public goods game to examine if responsibility for the financial welfare of others affects decisionmaking behaviour in two different types of decision environments. We find no evidence that responsibility affects individual risk preferences....

Using hypothetical lottery choices to measure risk preferences, Frederick (2005) finds that higher cognitive ability is associated with less risk aversion. This paper documents, however, that when using an incentive compatible measure of risk preference, attitudes towards risk are not associated...
