In this paper we use a very large matched database on firms and employees to analyze the use of temporary agencies by low earners, and to estimate the impact of temp employment on subsequent employment outcomes for these workers. Our results show that, while temp workers have lower earnings than...

Innovation in the U.S. economy is about employing and rewarding highly talented workers to produce new products. Using unique longitudinal matched employer-employee data, this paper makes a key connection between talent and firms in markets with risky product innovations. We show that software...

We use the National Longitudinal Survey of Youth 1997 cohort to examine mismatch between student ability and college quality. Mismatch has implications for the design of state higher education systems and for student aid policy. The data indicate substantial amounts of both undermatch (high...

This paper decomposes the participation process of a prototypical program into eligibility, awareness, application, acceptance and enrollment. With this decomposition, we determine the sources of unequal participation for different groups, and demonstrate that variables often have very different...

The key to estimating the impact of a program is constructing the counterfactual outcome representing what would have happened in its absence. This problem becomes more complicated when agents self-select into the program rather than being exogenously assigned to it. This paper uses data from a...

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...

A variety of criteria are relevant for evaluating alternative policies in democratic societies composed of persons with diverse values and perspectives. In this paper, we consider alternative criteria for evaluating the welfare state, and the data required to operationalize them. We examine sets...

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...

This paper examines the effect of the Worker Profiling and Reemployment Services (WPRS) system. This program 'profiles' UI claimants to determine their probability of benefit exhaustion (or expected spell duration) and then provides mandatory employment and training services to claimants with...

This paper develops and applies semiparametric econometric methods to estimate the form of selection bias that arises from using nonexperimental comparison groups to evaluate social programs and to test the identifying assumptions that justify three widely-used classes of estimators and our...
