Effects of extending paid parental leave on children’s socio-emotional skills and well-being in adolescence
利用丹麦2002年延长带薪育儿假的改革，研究发现更长的育儿假能提高青少年的幸福感、责任心和情绪稳定性，并减少缺勤，尤其对原本休假短的母亲的孩子效果最强。
We study how children’s socio-emotional skills and well-being in adolescence are affected by an increase in the duration of parental care during infancy. Exploiting a Danish reform that extended paid parental leave in 2002 and effectively delayed children’s entry into formal out-of-home care, we show that longer leave increases adolescent well-being, conscientiousness and emotional stability, and reduces school absenteeism. The effects are strongest for children of mothers who would have taken short leave in absence of the reform. This highlights how time spent with a parent is particularly productive during very early childhood.
