Improving the long-term life outcomes of disadvantaged youth remains a top policy priority in the United States, although identifying successful interventions for adolescents - particularly males - has proven challenging. This paper reports results from a large randomized controlled trial of an...

We present the results of three large-scale randomized controlled trials (RCTs) carried out in Chicago, testing interventions to reduce crime and dropout by changing the decision-making of economically disadvantaged youth. We study a program called Becoming a Man (BAM), developed by the...

There is growing concern that improving the academic skills of disadvantaged youth is too difficult and costly, so policymakers should instead focus either on vocationally oriented instruction for teens or else on early childhood education. Yet this conclusion may be premature given that so few...

This paper reports the results of two randomized field experiments, each offering different populations of youth a supported summer job in Chicago. In both experiments, the program dramatically reduces violent-crime arrests, even after the summer. It does so without improving employment,...

This paper examines the effectiveness of drug courts to reduce the size of the incarcerated drug-offending population using data from the Survey of Inmates in State Correctional Facilities and the Survey of Inmates in Local Jails. We find that very few of those entering state prison in 2004 or...

This paper is the introductory chapter for the forthcoming NBER volume Controlling Crime: Strategies and Tradeoffs. The Great Recession has led to cuts in criminal justice expenditures, and the trend towards ever-higher incarceration rates that has been underway since the 1970s in the U.S....

Head Start is a federal early childhood intervention designed to reduce disparities in preschool outcomes. The first randomized experimental study of Head Start, the National Head Start Impact Study (NHSIS), found impacts on academic outcomes of .15 to .3 standard deviations measured at the end...

In this paper we estimate the causal effects on child mortality from moving into less distressed neighborhood environments. We match mortality data to information on every child in public housing that applied for a housing voucher in Chicago in 1997 (N=11,848). Families were randomly assigned to...

Randomized controlled trials are increasingly used to evaluate policies. How can we make these experiments as useful as possible for policy purposes? We argue greater use should be made of experiments that identify behavioral mechanisms that are central to clearly specified policy questions,...

We examine long-term neighborhood effects on low-income families using data from the Moving to Opportunity (MTO) randomized housing-mobility experiment, which offered some public-housing families but not others the chance to move to less-disadvantaged neighborhoods. We show that 10-15 years...
