The Effect of Hospital Postpartum Care Regulations on Breastfeeding and Maternal Time Allocation
研究了美国州级医院产后护理法规对母乳喂养率的影响，发现法规使母乳喂养启动率提高3.8个百分点，并增加了母亲育儿时间，减少了正式工作时间。
We study the effects of state hospital regulations intended to increase breastfeeding by requiring certain standards of care during the immediate postpartum hospital stay. We find that these regulations significantly increased breastfeeding initiation by 3.8 percentage points (5.1 percent) and the probability of breastfeeding at 3 and 6 months postpartum by approximately 7 percent. We also provide evidence that these breastfeeding-promoting policies significantly increased maternal time spent on child care, crowding out time spent on formal work. Observed reductions in employment are concentrated among mothers with infants between zero and three months of age.
