The Impact of Welfare on Young Mothers' Subsequent Childbearing Decisions
利用美国青年纵向调查数据，检验福利水平及增量对已有子女的年轻母亲后续生育决策的影响，发现福利无显著影响。
The impact of welfare on fertility in the United States is explored focusing on the theory that some women have many children to increase their incomes and to prolong their stay on welfare rolls. The author examines the relationship between welfare and births to women who already have a child using data on young mothers from the National Longitudinal Survey of Youth (NLSY). I find that variations in welfare benefit levels and the incremental benefit have no statistically significant impacts on the subsequent childbearing decisions of young mothers in general nor on the subsequent childbearing decisions of women who received welfare in particular. Furthermore mothers who received welfare to support their first children are no more likely to have additional children in any given year through the age of 23. (EXCERPT)
