Results of the structural model rely on those open-source software packages:

- German tax and transfer system: gettsim.readthedocs.io
- Numerical optimization: estimagic.readthedocs.io

Policy takeaways: 1. As attitudes are important, effectiveness of policies limited in the short run. 2. They need to be considered when extrapolating average policy effects to different contexts. 3. Addressing heterogeneous subpopulations requires targeted policies.

Results: 1. Labor supply elasticities higher for traditional mothers 2. Policy facilitating access to full-time childcare has stronger effect on egalitarian mothers Implication: if distribution of attitudes changes over time, elasticities and policy effects change, as well

Second step: Study interaction of gender attitudes with hypothetical policies. Estimate a structural model of female labor supply. Elements: Discrete labor supply choice, human capital accumulation, life cycle perspective Novel feature: heterogeneity by gender role attitudes

Exploit eligibility-cutoff by birth date of the child Results: 👉 Traditional mothers reduce labor supply (46% stronger than baseline) 👉 Egalitarian mothers do not reduce labor supply

Now: Look at interaction with economic incentives using actual and hypothetical policy changes First step: Study introduction of a cash-for-care policy (`Betreuungsgeld`). Parents receive subsidy if they do not take up public childcare when child is one or two years old.

Measuring individual-level attitudes allows further analyses: 1. Study relation to background variables (explain only 13% of variation in attitudes) and control for them 2. Attitudes of the father predict maternal labor supply (in addition to mothers' attitudes) 👉 joint household decision

Event studies around birth of the first child: 👉 Pre birth: same labor supply for egalitarian and traditional mothers 👉 Post birth: egalitarians return much faster to the labor market -> 15% more likely to work, work 4 hours more, persistent effects

👉 GER panel data (pairfam) 👉 Gender role attitudes: views about appropriate role of mothers 👉 Measure attitudes before birth of the first child 👉 In main specification, consider two groups: `egalitarian` and `traditional` women (median split)

JMP alert 🎉 What drives maternal labor supply - a key factor for labor market inequalities? Gender role attitudes! We use reduced form and structural methods to show that they are of first-order importance, both directly and through the mediation of policies (w/ Tim Mensinger) 🧵👇
