  1. Note: Panel A displays the share of leave spells in the IABS that can be linked to childbirth in the Pension Register by month of birth (in the IABS data), after imposing the preferred restrictions. The last row reports the p-value for the hypothesis that the birth month dummies in a linear probability model are jointly equal to zero. Panel B reports results from linear probability models where the dependent variable is equal to 1 if the leave spell in the IABS is due to childbirth. The findings are based on Sample B. Robust standard errors in parentheses.
