Child Support Enforcement and Welfare Caseloads
利用1980-1999年美国州级面板数据，发现更有效的子女抚养费强制执行能显著降低福利案件数量，1999年约减少9%。
Although there is a large body of research devoted to the issue of the determinants of welfare caseloads, none of these studies has incorporated the effects of child support enforcement (CSE). We employ annual state panel data from 1980 to 1999 and find that states with more effective CSE have significantly lower welfare caseloads. The improvement in CSE over this period reduces welfare caseloads by about 9 percent in 1999. We also discover that individual child support variables may not be good indicators of state CSE vigor and that a CSE index that includes multiple dimensions of CSE is more likely to capture the multiplicative functions of CSE.
