Using data from the Head Start Impact Study, this paper examines variation in Head Start effects across individual children, policy-relevant subgroups of children, and Head Start centers. It finds that past estimates of the average effect of Head Start programs mask a wide range of relative program effectiveness.
Using an alternative to classical statistics, this paper reanalyzes results from three published studies of interventions to increase employment and reduce welfare dependency. The analysis formally incorporates prior beliefs about the interventions, characterizing the results in terms of the distribution of possible effects, and generally confirms the earlier published findings.

Evidence from a Sample of Recent CET Applicants
This working paper examines employment and earnings over a four-year period for a group of disadvantaged out-of-school youth who entered the Evaluation of the Center for Employment Training (CET) Replication Sites between 1995 and 1999. It assesses the importance of three key factors as barriers to employment: lack of a high school diploma, having children, and having an arrest record.
