Robert Axelrod's seminal round-robin computer tournaments for the repeated prisoner's dilemma have been hailed as the explanation of the evolution of cooperation. In this paper, Axelrod's results are systematically re-examined in the light of new insights about computer simulations. In...

Testing whether risk professionals (here insurers) behave differently under risk and ambiguity when they cover catastrophic risks (floods and earthquakes) and non-catastrophic risks (fires), this paper reports the results of the first field experiment in the United States designed to distinguish...

This article surveys the experimental economics approach to the study of religion. The field has a place in the context of the scientific study of religion generally and the social psychology of religion in particular, but employs distinct economic methods which promise new and different...

A Monte Carlo simulation study is carried out to examine the effects on study results of subjects completing a survey more than once. Three strategies subjects might use to do this - which is known as farming - are studied. Findings show that farming influences results and can cause both...

The standard chicken game is a popular model of certain important real scenarios but does not allow for the escalation behaviour these are typically associated with. This is problematic if the critical, final decisions in these scenarios are sensitive to previous escalation. We introduce and...

In this paper, we build on the emerging literature on group decision-making to study the so-called ‘group shift’ effect, i.e., groups are less risk-averse than individuals. Our study complements past research in two ways. First, we study the group shift effect under two sources of...
