Unlike previous attempts to implement cooperation in a prisoners’ dilemma gamewith an infinite horizon in the laboratory, we focus on extended prisoners’ dilemmagames in which a second (pure strategy) equilibrium allows for voluntary cooperationin all but the last round. Our four main...

We analyze the effects of asymmetric information concerning thesize of a pie on proposer behavior in three different bargaining situations:the ultimatum game, the Yes-No-game and the dictator game.Our data show that (a) irrespective of the information condition, proposergenerosity increases with...

Charness et al. (2007b) have shown that group membership has a strong effect on individualdecisions in strategic games when group membership is salient through payoff commonality.In this comment I show that their findings also apply to non-strategic decisions, even when nooutgroup exists, and I...

We experimentally investigate how affective processes influence proposers’and responders’ behaviour in the Ultimatum Game. Using a dualsystemapproach, we tax cognitive resources through time pressure andcognitive load to enhance the influence of affective processes on behaviour.We find that...

The study of gender differences in social preferences has shown mixedresults, preventing economists and other social scientists from drawingdefinitive conclusions on this topic. Several original investigations andexperimental reviews have hypothesized that the main reason of this heterogeneityof...

Contrary to the models of deterministic life cycle saving, we take itfor granted that uncertainty of one's future is the essential problem ofsaving decisions. However, unlike the stochastic life cycle models, we capturethis crucial uncertainty by a non-Bayesian scenario-based...

We perform an experimenta linvestigation using a dictator game inwhich individuals must make a moral decision —to give or not to give anamount of money to poor people in the Third World. A questionnaire inwhich the subjects are asked about the reasons for their decision showsthat, at least in...

I examine how financial incentives interact with intrinsic motivation and especially cognitive abilities in explaining heterogeneity in performance. Using a forecasting task with varying cognitive load, I show that the effectiveness of high-powered financial incentives as a stimulator of...

This paper extends existing evidence on the interaction between financial incentives and cognitive capital. I focus on the impact of task-specific cognitive capital, the role of which is central to the capital-labor-production framework of Camerer and Hogarth (1999) and has long been studied in...

Gneezy, List and Wu [Q. J. Econ. 121 (2006) 1283-1309] document that lotteries are often valued less than the lotteries’ worst outcomes. We show how to undo this result.
