This paper studies the relevance of equilibrium and nonequilibrium explanations of behavior, with respects to equilibrium refinement, as players gain experience. We investigate this experimentally using an incomplete information sequential move game with heterogeneous preferences and multiple...

An important branch of economic research on emotions has used power-to-take game experiments to study the impact of negative emotions, such as anger, irritation and contempt, on the decision to punish. We investigate experimentally to what extent the findings of this literature are driven by the...

We explore gender differences in preferences for competition and risk among children aged 9-12 in Colombia and Sweden, two countries differing in gender equality according to macro indices. We include four types of tasks that vary in gender stereotyping when looking at competitiveness: running,...

We explore gender differences in preferences for competition and risk among children aged 9-12 in Colombia and Sweden, two countries differing in gender equality according to macro indices. We include four types of tasks that vary in gender stereotyping when looking at competitiveness: running,...

Cooperation and competition are both essential elements of economic life. Here we explore how cooperativeness in a prisoner’s dilemma is correlated with competitiveness in a sample of 9-12 year old children in Colombia and Sweden. Using two different measures and four different tasks for...

This paper compares cooperation among Columbian and Swedish children aged 9-12. We illustrate the dynamics of the prisoner´s dilemma in a new task that is easily understood by children and performed during a physical education class. We find some evidence that children cooperate more in Sweden...

Social preferences have been shown to be an important determinant of economic decision making for many adults. We present a largescale experiment with 883 children and adolescents, aged eight to seventeen years. Participants make decisions in eight simple, oneshot allocation tasks, allowing us...

We devise a new experimental game by nesting a voluntary contributions mechanism in a broader spectrum of incentive schemes. With it, we study tensions between egalitarianism, equity concerns, self-interest, and the need for incentives. In a 2x2 design, subjects either vote on or exogenously...

This paper examines how third-party surveillance influences preferences over distributional outcomes. In addition, we examine what motivates people to invest economic resources to monitor decision-making processes. Our results show that a large majority of individuals is willing to pay for a...

People can become less cooperative when threatened with sanctions, and researchers have pointed to both 'intentions' and incentives as sources of this effect. This paper reports data from a novel experimental design aimed at determining the relative importance of intentions and incentives in...
