Knowledge of treatment effect heterogeneity or "essential heterogeneity" plays an important role in our understanding of how programs work and in the design of systems to allocate them among the eligible. This paper provides a relatively non-technical survey of the current state of the treatment...

[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...

The traditional data warehouse model is no longer able to keep up with the evolution and changing requirements of the data analytic world. As we see the concept of a logical data warehouse gain momentum, there's a resulting need to drive a portion of the analytics closer to where the data is...

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...
