This paper makes three primary contributions. First, we demonstrate the usefulness of general equilibrium models as tools with which to draw policy implications for policies implemented in practice only as small-scale social experiments. Second, we illustrate the usefulness of social experiments...

We consider the effects of student ability, college quality, and the interaction between the two on academic outcomes and earnings using data on two cohorts of college enrollees. Student ability and college quality strongly improve degree completion and earnings for all students. We find...

This chapter considers means-tested employment and training programs in the United States. We focus in particular on large, means-tested federal programs, including the Job Training Partnership Act (JTPA), its successor the Workforce Investment Act (WIA), that program's recent replacement, the...

We study the job training provided under the US Workforce Investment Act (WIA) to adults and dislocated workers in two states. Our substantive contributions center on impacts estimated non-experimentally using administrative data. These impacts compare WIA participants who do and do not receive...

This paper examines the performance of the JTPA performance system, a widely emulated model for inducing efficiency in government organizations. We present a model of how performance incentives may distort bureaucratic decisions. We define cream skimming within the model. Two major empirical...

This paper considers the statistical and economic justification for one widely-used method of adjusting data from social experiments to account for dropping-out behavior due to Bloom (1984). We generalize the method to apply to distributions not just means, and present tests of the key...

This paper demonstrates that even under ideal conditions, social experiments in general only uniquely determine the mean impacts of programs but not the median or the distribution of program impacts. The conventional common parameter evaluation model widely used in econometrics is one case where...

We document substantial variation in the effects of a highly-effective literacy pro-gram in northern Uganda. The program increases test scores by 1.40 SDs on average, but standard statistical bounds show that the impact standard deviation exceeds 1.0SD. This implies that the variation in effects...

Bucky's Tuition Promise (BTP) at the University of Wisconsin-Madison offers generous financial aid to low-income, in-state students. Unlike many similar programs at other public universities, financial eligibility for BTP depends solely on a family's Adjusted Gross Income (AGI), rather than on...

We provide simple tests for selection on unobserved variables in the Vytlacil-Imbens-Angrist framework for Local Average Treatment Effects (LATEs). Our setup allows researchers not only to test for selection on either or both of the treated and untreated outcomes, but also to assess the...
