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...

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 summarise our two sets of controlled experiments designed to see if single-sex classes within coeducational environments modify students’ risk-taking attitudes. In Booth and Nolen (2012b), subjects are in years 10 and 11, while in Booth, Cardona-Sosa and Nolen (2014), they are first-year...

Decision theory assumes that agents making choices assign subjective probabilities to outcomes, also at choices where information on probabilities is obviously absent. Yet, Skogh and Wu (2005) show that risk averse agents may gain by risk sharing also at unknown (and unassigned) probabilities of...

The recent literature on individual vs. group decisions over risk has brought about divergent results, mainly depending on the institutional rules through which groups take decisions. While some studies where group decisions relied on the majority rule showed no appreciable difference between...

This study contributes to the public debate on gender quotas and the literature on gender and risk taking by analysing how the level of risk taking within a group is influenced by its gender composition. In particular we look at the shift of risk taking between group and individual decisions and...
