Women are less likely than men to start firms and female entrepreneurs are less likely to succeed. This paper studies the effect of childbirth on women’s entrepreneurial activity. Drawing on rich administrative data from Canada and using an event study and instrumental variable design, I show that childbirth has substantial negative effects on women’s founding rates and firm performance, accounting for a large share of the gender gap in entrepreneurship. The impact spills over onto workers, who experience a decrease in earnings. The effects are permanent: entrepreneurial outcomes never recover to their pre-birth levels. The results are not due to a reduction in risk-taking and cannot be fully explained by household specialization based on labor market advantage. Childcare availability, progressive gender norms, and access to credit reduce the adverse effect of childbirth on the entrepreneurship gap.

Entrepreneurs with better diversified portfolios provide more insurance to employees against labor income risk: in a sample of over 524,000 Canadian firms and 858,000 owners, firms owned by more diversified entrepreneurs offer more stable jobs and earnings to employees when faced by idiosyncratic shocks. A one standard deviation increase in owner’s diversification reduces the shock’s pass-through rate to labor layoffs by 13% and to workers’ earnings by 41%. The data are consistent with such insurance being partly provided to retain valuable human capital and partly to avoid costly terminations. There is no evidence of insurance being priced in average wages.

This study examines the mining sector’s responsiveness to global commodity price shocks, with a focus on critical minerals essential for the low-carbon transition, such as cobalt, nickel, and lithium. First, we show that exploration and extraction activities are highly responsive to global commodity price fluctuations. Second, we analyze the reallocation of human capital from other sectors as sustainable mining emerges as a key industry. Our analysis considers both the flow of professionals from various industries into mining and the individuals who capitalize on these opportunities to establish new firms or become early-stage investors in mining ventures.
