题目: 少即是多：家庭规模如何影响长期人力资本与经济机会（Less is More: How Family Size in Childhood Affects Long-Run Human Capital and Economic Opportunity）

报告摘要:

This paper examines the impact of family size on children’s long-term wellbeing. The number of siblings is a prominent aspect of childhood family environments that affects parental time and resource investments. Leveraging temporal and county-level variation in access to abortion in the United States during the 1970s, my research design contrasts adult outcomes of children born just before an abortion clinic opened with adult outcomes in counties in which abortion remained difficult to obtain. The results suggest that access to abortion decreases the completed number of younger siblings. As their parents avoided unplanned children and achieved smaller family sizes, the children experienced significant improvements in their long-run outcomes, including increased educational attainment, greater labor-force participation, and higher neighborhood quality. The effects are larger in areas with greater exposure to safety net programs. These findings imply large, persistent returns to reproductive health policies that promote smaller families.
