New Evidence on the Long-Term Effects of Employment Training Programs
利用新数据追踪国家支持工作实验对青年和AFDC群体八年的收入影响，发现对AFDC群体收入有显著正向效果，成本可被抵消，但对青年无显著影响。
This research utilizes new data to track the earnings effect of the National Supported Work experiment (NSW) on the youth and Aid to Families with Dependent Children (AFDC) target groups for eight years following training. The research indicates that the NSW's effect on the AFDC recipients ranged from $375 to $525 in 1978 dollars during the years 1982-86. The sum of the estimated earnings effects for the AFDC treatments over the observed posttraining period more than offset the costs of the training program. The NSW was found to have no discernible effect on the earnings of the youth target group. Copyright 1992 by University of Chicago Press.
