Chapter 1. Undergraduate Gender Diversity and Direction of Scientific Research (with Ashley Wong) Can diversity lead to greater research focus on populations underrepresented in science? Diverse researchers can bring new questions and perspectives, but exposure to diversity may also inspire scientists, regardless of demographic identity, to pursue new topics. This paper studies a new determinant of research ideas: the diversity of the academic environment. Between 1960 and 1990, 76 all-male US universities, including many elite and prominent research institutions, transitioned to coeducation. Using a generalized difference-in-differences design, we document a 42% increase in the number of gender-related research publications authored by scholars at newly coed universities. This increase is explained by a combination of a more diverse researcher pool in terms of gender and prior research interests, as well as a shift in the research focus of individual scientists towards more gender-related topics. A bounding exercise suggests that the direct effects of the policy on scientists' research focus can account for more than half of these gains. These findings suggest that a diverse academic environment can influence the direction of scientific research. Chapter 2. Peer Effects and the Gender Gap in Corporate Leadership: Evidence from MBA Students (with Menaka Hampole and Ashley Wong) Women continue to be underrepresented in corporate leadership positions. This paper studies the role of social connections in women's career advancement. We investigate whether access to a larger share of female peers in business school affects the gender gap in senior managerial positions. Merging administrative data from a top-10 US business school with public LinkedIn profiles, we first document that female MBAs are 24 percent less likely than male MBAs to enter senior management within 15 years of graduation. Next, we use the exogenous assignment of students into sections to show that a larger proportion of female MBA section peers increases the likelihood of entering senior management for women but not for men. This effect is driven by female-friendly firms, such as those with more generous maternity leave policies and greater work schedule flexibility. A larger proportion of female MBA peers induces women to transition to these firms where they attain senior management roles. We find suggestive evidence that some of the mechanisms behind these results include job referrals and gender-specific information transmission. These findings highlight the role of social connections in reducing the gender gap in senior management positions. Chapter 3. Pension Caregiver Credits and the Gender Gap in Old-Age Income (with Fabio Blasutto and Ashley Wong) We study a 2001 pension insurance reform in Germany that introduced additional caregiver credits for working mothers with children between the ages of 3 and 10. Using administrative social security data from Germany combined with a difference-in-differences design, we find that the reform leads to a 66.5% increase in yearly retirement contributions during the eligibility period. 66% of the total effect can be explained by a change in the labor market outcomes of eligible mothers, while the remaining 34% is the mechanical effect of the reform. We find a significant increase in employment earnings, driven by both an increase in employment and a switch from marginal to employment subject to social security contributions. This translates into a 9.1 percentage point (18.3%) reduction in the gender gap in lifetime non-marginal earning points. Finally, a simple life-cycle model predicts that the pension reform leads to a 9.8\% increase in retirement income and a 12% reduction in the gender gap in old-age income.
