Knowledge that Transforms

Using multiple administrative data sources from Norway, we examine how firm performance changes after entrepreneurs become parents.Female-owned businesses experience a substantial decline in profits, steadily decreasing to 30% below baseline ten years post-childbirth.In contrast, male-owned businesses show no decline, often growing in revenues and costs after childbirth.The profit decline for female-owned firms is most pronounced among highly capable entrepreneurs, women who are majority owners, and those with working spouses.Entrepreneurial effort is key to performance, and our findings suggest that time demands from childbirth and childcare are a significant determinant of the decline in firm profits.

This paper estimates the causal impacts on child skills and the mechanisms producing these impacts using data from a randomized control experiment. We study a widely emulated early-childhood home visiting program and show the feasibility of replicating it at scale. We go beyond reporting treatment effects as unweighted item scores and assess item difficulties. To interpret treatment effects, we estimate individual-level latent skills and compare treatments and controls. The program substantially improves multiple skills. We decompose the source of treatment effects and find that enhancements in latent skills explain most of the conventional treatment effects for language and cognition.
