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...

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...

Many studies document systematic gender differences in a variety of important economic preferences, such as risk-taking, competition and pro-sociality. One potential implication of this literature is that increased female representation in decision-making bodies may significantly alter...

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

There is substantial evidence that women tend to support different policies and political candidates than men. Many studies also document gender differences in a variety of important preference dimensions, such as risk-taking, competition and pro-sociality. However, the degree to which...

Recent self-reported and cross-sectional survey evidence documents high levels of mental health problems among PhD students. We study the impact of PhD studies on mental health care uptake using Swedish administrative records of prescriptions for psychiatric medication for the full population of...

Economic research on gender gaps in preferences and economic outcomes has focused on variation with respect to sex-a binary classification as either a "man" or "woman." We validate a novel and simple measure of self-reported continuous gender identity (CGI) and explore whether gender identity...

This paper explores the link between what people say they prefer to do and what they actually do. Using data from an experimental project explored trust and pro-sociality for representative samples of individuals in six Latin American capital cities, the paper links the results of these...

This paper explores the extent to which individuals trust, reciprocate, cooperate and pool risk by using a battery of field experiments containing the trust game, the voluntary contributions mechanism and the risk pooling game; applied in six capital cities in Latin America. The results suggest...
