What Is the Case for Paid Maternity Leave?
研究了挪威将带薪产假从18周扩大到35周的政策效果，发现产假增加对儿童教育、父母收入和生育等影响很小，但再分配效果为负且增加税收成本。
We assess the case for generous government-funded maternity leave, focusing on a series of policy reforms in Norway that expanded paid leave from 18 to 35 weeks. We find the reforms do not crowd out unpaid leave and that mothers spend more time at home without a reduction in family income. The increased maternity leave has little effect on children's schooling, parental earnings and labor force participation, completed fertility, marriage, or divorce. The expansions, whose net costs amounted to 0.25% of GDP, have negative redistribution properties and imply a considerable increases in taxes at a cost to economic efficiency.
