Abstract
Using a sample of 2072 women who participated in New Jersey's Family Development Program experiment during 1992-1996, we compare three welfare-to-work strategieslabor force attachment (LFA), human capital investment (HCI), and a mixed strategyemploying traditional effectiveness analysis within an experimental design and an efficacy approach which controls for selective participation by experimental and control subjects. Controlling for selective participation, we find that each year of participation in LFA increases the probability of employment by about 3 percent. In our earnings analyses we find that HCI participants earn about $163 less per year of exposure to this strategy.
