When Sarah Meets Lawrence: The Effects of Coeducation on Women's College Major Choices.

We leverage variation in the adoption of coeducation by U.S. women's colleges to study how exposure to a mixed-gender collegiate environment affects women's human capital investments. Our event-study analyses of newly collected historical data find a 3.0-3.5 percentage-point (30-33%) decline in the share of women majoring in STEM. While coeducation caused a large influx of male peers and modest increase in male faculty, we find no evidence that it altered the composition of the female student body or other gender-neutral inputs. Extrapolation of our main estimate suggests that coeducational environments explain 36% of the current gender gap in STEM.

Sexual Assault Experiences in the Active-Component Army: Variation by Year, Gender, Sexual Orientation, and Installation Risk Level.

To better understand the circumstances surrounding sexual assault in the Army, RAND Arroyo Center researchers created descriptions of active-component soldiers' most serious sexual assault experiences using data from the 2016 and 2018 Workplace and Gender Relations Survey of Active Duty Members. In this study, researchers describe the most common types of behaviors that occurred, characteristics of alleged perpetrators, and times and places in which the experiences occurred. They also explore differences by gender, sexual orientation, and installation risk level. Nearly 90 percent of victims believed that the assault was committed for a sexual reason, and more than half indicated that the assault was meant to be abusive or humiliating. The typical perpetrator of victims' most serious sexual assault experiences was a male enlisted member of the military acting alone. Perpetrators were most often a military peer of the victim; perpetrators who were strangers to the victim were uncommon; and assaults by spouses, significant others, or family members were comparatively rare. Approximately two-thirds of victims' most serious experience of sexual assault occurred at a military installation. The authors found substantial differences by gender, especially in terms of the types of sexual assault behaviors victims experienced and in terms of the setting in which victims were sexually assaulted. The authors also found some evidence suggesting that sexual minorities-that is, individuals who identify with a sexual orientation other than heterosexual-may experience more-violent sexual assaults and more assaults that are meant to abuse, humiliate, haze, or bully, especially among men.
