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...

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

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...

This paper reports an experiment designed to test whether prior consultation within a group affects subsequent individual decision making in tasks where demonstrability of correct solutions is low. In our experiment subjects considered two paintings created by two different artists and were...

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...

We report a controlled laboratory experiment examining risk-taking and information aggregation in groups facing a common risk. The experiment allows us to examine how subjects respond to new information, in the form of both privately observed signals and signals reported from others. We find...

The unravelling prediction of disclosure theory relies on the idea that strategic forces lead firms (information senders) to voluntarily disclose information about the quality of their products provided the information disclosed is verifiable and the costs of disclosure are negligible. This...

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 examine the relationship between confidence in own absolute performance and risk attitudes using two confidence elicitation procedures: self-reported (non-incentivised) confidence and an incentivised procedure that elicits the certainty equivalent of a bet based on performance. The former...
