Using Swedish population register data on cohorts born 1982-1994 (N=1,087,750), we examine the effects of preterm births on school grades using sibling fixed effect models which compare individuals with their non-preterm siblings. We test for heterogeneous effects by degree of prematurity, as...

To investigate the effects of reducing the intensity of tracking, this study exploits reforms across German states which combined the two lower secondary school tracks, sometimes additionally offering the possibility to acquire a university entrance qualification. Using a...

This paper studies the effect of longer school days - induced by voluntary all-day programs in German primary schools - on school performance. We combine data from the National Educational Panel Study covering 5348 primary school students with municipality-level information on all-day school...

Numerous countries require teachers to assign comportment grades rating students’ social and work behavior in the classroom. However, the impact of such policies on student outcomes remains unknown. We exploit the staggered introduction of comportment grading across German federal states...

We exploit a recent state-level reform in Germany that granted parents the right to decide on the highest secondary school track suitable for their child, changing the purpose of the primary teacher's recommendation from mandatory to informational. Applying a disaggregated synthetic control...

Patience and risk-taking – two cultural traits that steer intertemporal decision-making – are fundamental to human capital investment decisions. To understand how they contribute to international differences in student achievement, we combine PISA tests with the Global Preference Survey. We...

We report results from a large-scale, pre-registered randomized field experiment in 159 Norwegian schools over four years. The intervention includes students aged 7-9 and consists of pulling students from their regular mathematics classes into small, homogenous groups for mathematics instruction...

We investigate the impact of the presence of university dropouts on the academic success of first-time students. Our identification strategy relies on quasi-random variation in the proportion of returning dropouts. The estimated average zero effect of dropouts on first-time students’ success...

Decisions about admission to selective schools usually rely on performance measures. To reach a required achievement threshold students may make use of additional resources, such as private tutoring. We investigate how the use of private tutoring relates to the transition probability to an...

We provide evidence about the mechanisms linking resource-related income shocks to conflict. Combining temporal variation in international drug prices with spatial variation in the suitability to produce opium, we show that higher drug prices reduce conflict over the 2002-2014 period in...
