Abstract: 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. Qualitative interviews reveal that some of the mechanisms behind these results include emotional support, job referrals, and information transmission. These findings highlight the role of social connections in reducing the gender gap in senior management positions.

Abstract: Can diversity lead to greater research focus on populations underrepresented in science? Between 1960 and 1990, 76 all-male US universities transitioned to coeducation. Using a generalized difference-in-differences design, we find that coeducation led to a 44% increase in gender-related research publications. This increase is driven by research focused on female subjects and gender differences. While coeducation led to a compositional shift with more women and researchers interested in gender topics, much of the  increase comes from male incumbent researchers shifting their research focus toward gender-related topics. The results support interaction with more diverse students and peers as key underlying mechanisms.  

Abstract: This paper presents new evidence on the relationship between motherhood, maternity leave policies, and unemployment insurance (UI) participation. Using German administrative data, we show that over 32% of mothers received UI benefits, concentrated in the months after the expiration of paid maternity leave. We show that extensions of maternity leave in Germany reduce mothers' UI take-up by 19%. The timing of the reduction suggests mothers use UI as income replacement in the absence of paid leave. Importantly for our welfare calculations, the reduction in UI benefits is substantial and represents 68% of the increase in maternity leave benefits.

Abstract: Female-owned businesses continue to be smaller and less profitable than male-owned firms. We conduct an RCT in Ghana on a sample of 1,771 growth-oriented female entrepreneurs to investigate the effect of online networking groups on firm performance. We find that access to online networking opportunities leads to greater innovation, better business practices and higher profits by 21%. The increase in profits is concentrated in the upper tail of the distribution. The treatment shifts business collaborations from friends and family members to business network members in the intervention. We find the largest effects for those in groups with more-educated, higher-quality, and more diverse entrepreneurs. Our findings reveal that a low-cost, light-touch online intervention that increases networking opportunities can effectively improve outcomes of female-owned firms.

Work in Progress

Abstract: 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 earning points. Finally, a simple life-cycle model predicts that the pension reform leads to a 6.5% reduction in the gender gap in old-age income.

Abstract: High transaction and contracting costs are often thought to create credit and savings market failures in developing countries. The microfinance movement grew largely out of business process innovations and subsidies that reduced these costs. We examine an alternative approach, one that infuses no external capital and introduces no change to formal contracts: an improved “technology” for managing informal, collaborative village-based savings groups. Such groups allow, in theory, for more efficient and lower-cost loans and informal savings, and in practice have been scaled up by international non-profit organizations to millions of members. Individuals save together and then lend the accumulated funds back out to themselves. In a randomized evaluation in Mali, we find improvements in food security, consumption smoothing, and buffer stock savings. Although we do find suggestive evidence of higher agricultural output, we do not find overall higher income or expenditure. We also do not find downstream impacts on health, education, social capital, and female decision-making power. Could this have happened before, without any external intervention?  Yes. That is what makes the result striking, that indeed there were no resources provided nor legal institutional changes, yet the NGO-guided, improved informal processes led to important changes for households.
