How do financial frictions affect the type of human capital investments that students make in college? To study this question, I build a novel dataset covering more than 700,000 U.S. students, merging commencement records with address histories, credit bureau records, and professional resumes. I document that students trade-off initial earnings against lifetime earnings when choosing college majors, and that students from low-income families are more likely to choose majors associated with higher initial earnings but lower lifetime earnings. I provide causal estimates of how student debt affects this trade-off using the staggered implementation of Universal No-Loan Policies across 22 universities from 2001 to 2019. I find that students who are required to take on more student loans to finance their education choose majors with higher initial earnings but lower lifetime earnings. Furthermore, student debt differentially affects students depending on their family backgrounds: Students who grew up in low-income families display greater sensitivity to changes in student debt. Finally, I show that student debt leads to different job profiles and earnings later in life. Combined, these findings highlight the role of financial frictions in human capital investments and subsequent labor market trajectories.

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 random 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.
