Description:
We investigate the role played by the social environment in the development of gender differences in competitiveness and earnings expectations. First, we find that the gender gap in competitiveness and earnings expectations is more pronounced among adolescents with low socioeconomic status (SES). We further document that there is a positive association between the competitiveness of mothers and daughters, but not between mothers and sons. Second, we show that a randomized mentoring intervention that exposes low-SES children to predominantly female role models causally affects girls' willingness to compete and narrows both the gender gap in competitiveness as well as earnings expectations.
