We compare how children aged 9-12 in Colombia and Sweden cooperate in a Prisoner's Dilemma. We introduce a new measurement device for cooperation that can be easily understood by children. There is some evidence of more cooperation in Sweden than in Colombia. Girls in Colombia are less...

We look at gender differences in preferences for altruism, risk and competition in math and word search among adolescents in Sweden. We find that girls are more altruistic and less risk taking than boys. We find no gender gap in performance change when comparing performance under non-competition...

Recent studies find that women are less competitive than men. This gender difference in competitiveness has been suggested as one possible explanation for why men occupy the majority of top positions in many sectors. In this study we explore competitiveness in children, with the premise that...

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,...

Social hierarchy is persistent in all almost all societies. Social norms and their enforcement are part of sustaining hierarchical systems. This paper combines social status and norm enforcement, by introducing status in a dictator game with third party punishment. Status is conveyed by surname;...

Economic research on gender gaps has focused on variation based on the binary classification of "men" and "women". We explore whether a self-reported continuous measure of gender identity (CGI) explains variation in economic decisions and outcomes beyond the relationship with binary gender. We...

We study whether one reason behind female underrepresentation in leadership is that female leaders are less effective at coordinating followers' actions. Two experiments using coordination games investigate whether female leaders are less successful than males in persuading followers to...

We study the stability of voluntary cooperation in response to varying group growth rates. Using a laboratory public-good game, we construct a situation where increasing group size yields potential efficiency gains, but only with sustained cooperation. We then study the effect of exogenously...

We study the stability of voluntary cooperation in response to varying rates at which a group grows. Using a laboratory public-good game with voluntary contributions and economies of scale, we construct a situation in which expanding a group’s size yields potential efficiency gains, but only...

A recent literature emphasizes the importance of the gender gap in willingness to compete as a partial explanation for gender differences in labor market outcomes. However, whereas experiments investigating willingness to compete typically do so in anonymous environments, real world competitions...
