  1. Note 1: Control variables include work experience (quadratic), educational categories, dummies for whether the respondent believes in traditional gender roles, whether the respondent has any children, if the youngest child is below six, yearly age dummies, region of residence dummies, and year dummies. We also control for spouse’s age, educational categories, and annual income. Note 2: For OLS and IV regressions, t-stats reported are based on standard errors clustered at the individual level. For the sibling FE model, the t-stats reported are based on standard errors clustered at the family level. *** p < 0.01, ** p < 0.05, and * p < 0.10
