Female neighbors and careers in science
利用希腊学生数据，研究发现同年龄段女性邻居比例越高，男女学生的高中和大学成绩越好，且女生更可能选择STEM专业和高收入职业，社区公共空间会放大这一效应。
How much does your neighbor impact your test scores and career? In this paper, we examine how an observable characteristic of same-age neighbors—their gender—affects a variety of high school and university outcomes. We exploit randomness in the gender composition of local cohorts at birth from one year to the next. In a setting in which school assignment is based on proximity to residential address, we define as neighbors all same-cohort peers who attend neighboring schools. Using new administrative data for the universe of students in consecutive cohorts in Greece, we find that a higher share of female neighbors improves both male and female students’ high school and university outcomes. We also find that female students are more likely to enroll in STEM disciplines that promote innovation and pursue more financially rewarding career paths when they are exposed to a higher share of female neighbors. We collect rich qualitative geographic data on communal spaces (e.g., churches, libraries, parks, Scouts and sports fields) to understand whether access to spaces of social interaction drives neighbor effects. We find that communal facilities amplify neighbor effects among females.
