We study the role of professional networks in facilitating the escape of persecuted academics from Nazi Germany. From 1933, the Nazi regime started to dismiss academics of Jewish origin from their positions. The timing of dismissals created individual-level exogenous variation in the timing of...

A growing literature establishes that high quality early childhood interventions targeted toward disadvantaged children have substantial impacts on later life outcomes. Little is known about the mechanisms producing these impacts. This paper uses longitudinal data on cognitive and personality...

In the 1960s and 1970s, many states introduced grants for school districts offering kindergarten programs. This paper exploits the staggered timing of these initiatives to estimate the long-term effects of a large public investment in universal early education. I find that white children aged...

Between 1898 and 1948, English was the language of instruction for most post-primary grades in Puerto Rican public schools. Since 1949, the language of instruction in all grades has been Spanish. We use this policy change to estimate the effect of English-intensive instruction on the...

Between 1972 and 1978 U.S. high schools rapidly increased their female athletic participation rates - to approximately the same level as their male athletic participation rates - in order to comply with Title IX, a policy change that provides a unique quasi-experiment in female athletic...

Theories of market failures and targeting motivate the promotion of entrepreneurship training programs and generate testable predictions regarding heterogeneous treatment effects from such programs. Using a large randomized evaluation in the United States, we find no strong or lasting effects on...

Non-family-based institutions for socializing young people may play a vital role in creating close-knit, inclusive communities. We study the potential for youth camps—integrating rituals, sports, and civics training—to strengthen intergroup cohesion. We randomly assigned Hindu and Muslim...

By the 2008/09 school year the federal state of North Rhine-Westphalia (Germany) abolished binding school catchment areas (SCAs) in all municipalities. The reform has been controversial and it was feared that school choice would increase ethnic segregation. Using data on all primary schools, we...

We study whether early tracking of students based on ability increases migrant-native achievement gaps. To eliminate confounding impacts of unobserved country traits, we employ a differences-in-differences strategy that exploits international variation in the age of tracking as well as student...
