摘要：
Labor supply theory predicts systematic heterogeneity in the impact of recent welfare reforms on earnings, transfers, and income. Yet most welfare reform research focuses on mean impacts.
The study investigate the importance of heterogeneity using randam assignment data from Connecticut's Jobs First waiver, which features key elements of post-1996 welfare programs.
Esitmated quantile treatment effects exhibit the substantial heterogeneity predicted by labor supply theory. Thus mean impacts miss a great deal. Looking separately at samples of dropouts
and other women does not improve the performance of mean impacts. It is thus concluded that welfare reform's effects are likely both more varied and more extensive than has been recognized.
