Nevertheless She Persisted? Gender Peer Effects in Doctoral STEM Programs
研究STEM博士项目中同伴性别构成对女性坚持和毕业的影响，发现无女性同伴时女性毕业率显著低于男性，而增加女性同伴比例能提升女性按时毕业概率。
We study the effects of peer gender composition in STEM doctoral programs on persistence and degree completion. Leveraging unique new data and quasi-random variation in gender composition across cohorts within programs, we show that women entering cohorts with no female peers are 11.7pp less likely to graduate within 6 years than their male counterparts. A 1 sd increase in the percentage of female students differentially increases women's probability of on-time graduation by 4.4pp. These gender peer effects function primarily through changes in the probability of dropping out in the first year of a Ph.D. program.
