AFDC, SSI, and Welfare Reform Aggressiveness
研究AFDC改革是否影响另一项目SSI的受助人数，发现积极改革的州中女性户主家庭领取SSI的概率增加21.6%，表明一个项目受助人数减少不等于接受公共援助的家庭总数等量减少。
Abstract Welfare reform has made receipt of cash benefits more difficult and less attractive for single mothers. We examine whether reforms of AFDC affected caseloads of another program—Supplemental Security Income (SSI). We exploit state variation in welfare reform over time, and find that femaleheaded households in states aggressively pursuing welfare reform were 21.6 percent more likely to receive SSI. This implies that a decrease in caseloads in one program cannot be interpreted as an equal-sized decrease in the number of families receiving public assistance. In addition, our results have policy implications for the well-being of families affected by welfare reform time limits.
