Some countries, notably those which have long had a weak history of vocational education like the UK and the US, have recently seen a rapid expansion of hybrid schools which provide both general and vocational education. England introduced "University Technical Colleges" (UTCs) in 2010 for...

This paper estimates labor-market returns for students pursuing certificates or associate's degrees in eight broad fields of study at community colleges and for-profit institutions. The data contain 400,000 students beginning their studies between 2005 and 2012 in one state. We estimate two-step...

We use a change in Iceland’s education system as a natural experiment to measure the effect of years spent in upper secondary school on subsequent first year outcomes at university. The duration of Iceland´s upper-secondary education was shortened by one year through compression of the...

Almost all countries worldwide closed schools at the outbreak of the Covid-19 crisis. I document that schooling time dropped on average by -55% in the US and -45% in Germany from the onset of the crisis to the summer of 2021. In the US, schools were closed longer in richer than in poorer areas,...

This paper studies the impact of a desegregation ruling on several medium-run outcomes. This ruling mandates that seven school districts, which serve higher-income, predominantly-white families, accept a group of minority elementary school students who apply to transfer from a nearby,...

We study the effect of the world's largest school feeding program on children's learning outcomes. Staggered implementation across different states of a 2001 Indian Supreme Court Directive mandating the introduction of free school lunches in public primary schools generates plausibly exogenous...

We identify externalities in human capital production function arising from sibling spillovers. Using regression discontinuity design generated by school-entry cutoffs and school records from one district in Florida, we find positive spillover effects from an older to a younger child in less...

While several studies suggest that stress-related mental health problems among school children are related to specific elements of schooling, empirical evidence on this causal relationship is scarce. We examine a German schooling reform that increased weekly instruction time and study its...

We exploit variation stemming from school consolidations in Denmark from 2010-2011 to analyze the impact on student achievement as measured by test scores. For each student we observe enrollment and test scores one year prior to school consolidation and up to four years after. We find that...

Most studies find little to no effect of classroom computers on student achievement. We suggest that this null effect may combine positive effects of computer uses without equivalently effective alternative traditional teaching practices and negative effects of uses that substitute more...
