Peer gender and educational choices

We use idiosyncratic variation in gender composition across cohorts within Norwegian lower secondary schools to analyze the impact of female peers on students’ educational choices. We find that having more female peers in lower secondary school increases the probability of choosing STEM over language subjects in upper secondary school for both girls and boys. It also increases the probability of choosing a vocational track instead of an academic track. Registry data and survey evidence suggest that potential mechanisms are related to relative performance in STEM subjects, as well as less gender discrimination for girls and increased willingness to compete for boys.
