Does Access to Family Planning Increase Children’s Opportunities?
研究了美国1964-1973年间县级计划生育项目的引入对儿童经济资源的影响，发现项目启动后出生的孩子家庭收入提高2.8%，贫困概率降低7%，接受公共援助的概率降低12%。
This paper examines the relationship between parents' access to family planning and the economic resources of their children. Using the county-level introduction of U.S. family planning programs between 1964 and 1973, we find that children born after programs began had 2.8% higher household incomes. They were also 7% less likely to live in poverty and 12% less likely to live in households receiving public assistance. A bounding exercise suggests that the direct effects of family planning programs on parents' resources account for roughly two-thirds of these gains.
