Temporary help services (THS) firms are increasing their hiring of disadvantaged individuals and claiming more subsidies for doing so. Do these subsidies-the Work Opportunity Tax Credit (WOTC) and Welfare-to-Work Tax Credit (WtW)-create incentives that improve employment outcomes for THS...

[Conclusions] This paper has reviewed and commented on recent developments in evaluation research. I have outlined recent methodological developments and their implications for evaluation practice and policy. I have also provided copious citations to the technical literature related to these...

This paper considers the use of statistical profiling to allocate persons to alternative options within government programs, or to participation or non-participation in programs. Profiling has been used in the United States to allocate unemployment insurance (UI) claimants to reemployment...

This paper introduces an innovative test of search and matching models using the exogenous variation available in experimental data. We take an off-the-shelf search model and calibrate it to data on the control group from a randomized social experiment. We then simulate a program group from a...

This paper makes three contributions to the literature on program evaluation. First, we construct a model that is well-suited to conduct equilibrium policy experiments and we illustrate effectiveness of general equilibrium models as tools for the evaluation of social programs. Second, we...

This paper introduces an innovative test of search and matching models using the exogenous variation available in experimental data. We take an off-the-shelf Pissarides matching model and calibrate it to data on the control group from a randomized social experiment. We then simulate a program...

In this paper we provide new and convincing evidence on the presence and magnitude of feedback effects associated with 'make work pay' policies currently under consideration in the US, Canada, the UK and other developed countries. We build a general equilibrium model of the labor market and use...

This paper examines the long-term impacts on health and healthy behaviors of two of the oldest and most widely cited U.S. early childhood interventions evaluated by the method of randomization with long-term follow-up: the Perry Preschool Project (PPP) and the Carolina Abecedarian Project (ABC)....

This paper develops and applies a Bayesian approach to Exploratory Factor Analysis that improves on ad hoc classical approaches. Our framework relies on dedicated factor models and simultaneously determines the number of factors, the allocation of each measurement to a unique factor, and the...

This paper organizes and synthesizes the literature on early childhood education and childcare. In it, we go beyond meta-analysis and reanalyze primary data sources in a common framework. We consider the evidence from means-tested demonstration programs, large-scale means-tested programs and...
