Work Package 1: Motherhood and the Gender Gap in Self-Employment
We analyzed Dutch administrative microdata using an event-study design to document the impact of childbirth on men’s and women’s trajectories in self-employment. The analysis linked childbirth records with business ownership and financial outcomes, allowing us to track self-employment participation, profits, and industry specialization before and after childbirth. We find a significant motherhood effect on self-employment. Six years after childbirth, mothers experience a 16% decline in self-employment and a 26% decline in profits compared to fathers. We also show that women tend to shift into more flexible, female-customer-oriented industries following childbirth. A full draft of the paper has been completed, co-authored with Mery Ferrando, Teodora Tsankova, and Francesca Truffa, and submitted to a journal.
Work Package 2: Female Entrepreneurship and Professional Networks
We designed and implemented a randomized controlled trial (RCT) in Ghana with a sample of 1,771 growth-oriented female entrepreneurs. Women were randomly assigned to online networking groups via WhatsApp, and we tracked firm outcomes using survey data. The analysis focused on business practices, innovation, profitability, and the composition of business collaborations. We find that access to online networking groups led to greater innovation, improved business practices, and a 21% increase in profits. These effects were concentrated in the upper tail of the distribution and were largest for women placed in groups with more-educated, higher-quality, and more diverse peers. The intervention also shifted collaborations away from friends and family towards professional contacts in the groups. The draft paper has been completed (with Edward Asiedu, Monica Lambon-Quayefio, and Francesca Truffa) and submitted to a journal. This study was awarded the IGL Annual Research Prize for Best Experimental Paper by Junior Scholars in 2025.
Work Package 3: Gender Diversity and Innovation in Science
We assembled and cleaned historical data on U.S. universities and scientific publications to study the impact of coeducation on research directions and recognition of women’s work. The analysis uses a difference-in-differences design, exploiting variation in when universities transitioned to coeducation between 1960 and 1990. Using large-scale publication data (Microsoft Academic Graph), combined with natural language processing techniques, we analyze how exposure to female undergraduates influenced faculty research agendas and citation patterns. Preliminary results show that the transition to coeducation was associated with shifts in research topics towards those more frequently pursued by women and changes in citation patterns, suggesting increased recognition of female-authored work. These results have been presented at academic workshops and conferences, and a draft paper is in progress (with Francesca Truffa).
