Daddy’s Girl

Using Danish registry data, we study how managers’ gender attitudes shape gender inequality in the workplace by exploiting the birth of a daughter – as opposed to a son – as a plausibly exogenous shock to male managers’ gender attitudes. Comparing within-firm changes in women’s labor outcomes depending on the gender of the manager’s newborn child, we find that women’s relative earnings and employment increase by 4.4% and 2.9% respectively following the birth of the manager’s first daughter. These effects are driven by an increase in managers’ propensity to substitute male hires with female hires that have comparable education, hours worked, and earnings. Consistent with this substitution channel, we do not detect any significant effect on firm performance. Because these effects emerge rapidly and persist over time, we can rule out the need for prolonged exposure to gender issues or for personal incentives tied to improving conditions for their own daughters as prerequisites for managers to promote gender equality within their firms.

Executive Summary

The study investigates how the birth of a daughter, as opposed to a son, acts as an exogenous shock to male managers' gender attitudes in the workplace, using Danish registry data. The research compares within-firm changes in women’s labor outcomes following the birth of a manager's first daughter versus a son. The results indicate that following the birth of a manager's first daughter, women’s relative earnings and employment increase by 4.4% and 2.9%, respectively. These effects are attributed to an increased propensity for managers to substitute male hires with female hires who have comparable education, hours worked, and earnings. The study found no significant effect on firm performance, suggesting that the observed changes in outcomes do not correlate with firm performance metrics. Furthermore, the rapid emergence and persistence of these effects suggest that personal incentives related to daughters are not prerequisites for managers promoting gender equality.

Full Take

The finding that the birth of a daughter drives positive shifts in women's labor outcomes through hiring substitution is a powerful mechanism suggesting that deeply ingrained managerial biases can be altered by proximal life events, even when controlling for objective factors like education and hours worked. The lack of correlation with firm performance suggests that these changes operate at an individual or micro-level behavioral adjustment rather than as systemic organizational corrections. This challenges narratives that require prolonged exposure to gender issues or external incentives for promoting equality within firms before change occurs; the data implies internal shifts can be swift. The implications point toward recognizing how personal demographic markers interact with existing power dynamics in hiring, suggesting that structural inequality is mediated by subjective managerial perception that is sensitive to familial experience. Further inquiry should focus on whether this substitution effect scales across different types of managerial roles or firms, and what role the differential exposure to these gendered experiences plays in long-term organizational commitment versus short-term outcome metrics.
