There is growing concern that it is too difficult or costly to substantially improve the academic skills of children who are behind in school once they reach adolescence. But perhaps what we have tried in the past relies on the wrong interventions, failing to account for challenges like the...

We study how reported sexism in the population affects American women. Fixed-effects and TSLS estimates show that higher prevailing sexism where she was born (background sexism) and where she currently lives (residential sexism) both lower a woman's wages, labor force participation and ages of...

In response to budget problems, many urban school systems reduced resources for getting students to come to school, like truancy officers. Chicago, for instance, went from 150 truancy officers down to, in 1991, a total of zero. Is that a good idea? We explore here the effects of increased...

We revisit the early months of the Covid-19 pandemic to examine whether restaurant foot traffic reveals changes in sentiment towards ethnic groups. Our findings show reduced demand for dining at Asian restaurants located inside Asian enclaves, while outside enclaves, the decline in visits to...

High-dosage tutoring is an effective way to improve student learning (Nickow et al., 2024; Guryan et al., 2023). Finding ways to deliver high-dosage tutoring at large scale remains a challenge. Two primary challenges to scaling are cost and staffing. One possible solution is to reduce costs by...

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...

The epidemic of youth violence in the United States peaked in 1993 and has been followed by a rapid, sustained drop. In parallel with our earlier treatment (Cook and Laub 1998), we assess two types of explanation for this drop -- those that focus on 'cohort' effects (including the effects of...

We analyze a sample of 47 major US cities to illuminate the mechanisms that lead Right-to-Carry concealed handgun laws to increase crime. The altered behavior of permit holders, career criminals, and the police combine to generate 29 and 32 percent increases in firearm violent crime and firearm...

In 1954 the Supreme Court of the United States ruled that separate schools for black and white children were 'inherently unequal.' This paper studies whether the desegregation plans of the next 30 years in fact benefited the black students for whom the plans were designed. Analysis of data from...
