Disruptions in family life can take many forms, but all have the potential to impact student learning. With school administrative data matched to birth records, I estimate the effect of unexpected changes in the home environment, or family shocks, on achievement. Identification comes from...

Children with lower socioeconomic status (SES) tend to benefit more from early child care, but are substantially less likely to be enrolled. We study whether reducing behavioral barriers in the application process increases enrollment in child care for lower-SES children. In our RCT in Germany...

Proponents of tracking argue that the creation of more homogeneous classes increases effciency while opponents point out that tracking aggravates initial differences between students. We estimate the effects on the intergenerational transmission of education of a reform that delayed tracking by...

During the pandemic, many measures were taken to prevent the spread of Covid-19. Some of these measures, such as school closures, directly affected students. Children from different backgrounds are likely to have different abilities to cope with the challenges of the pandemic and associated...

We implement a teaching methodology aimed at improving primary school children's mathematical skills. The methodology, grounded in active and cooperative learning, focuses on peer interaction, sharing of ideas, learning from mistakes, and problem solving. We evaluate the causal effect of the...

This article reviews empirical evidence on the early tracking system in Germany and the educational inequalities associated with it. Overall, the literature confirms the existence of considerable social, ethnic, gender- and age-related inequalities in secondary school track placement. Studies on...

This study reports a randomized controlled trial to improve teacher-student-parent feedback, conducted in a rural county in China with many left-behind children. Data are collected from over 4,000 primary schoolchildren (8 to 10 years old) over two school terms. We find that bi-weekly student...

Do increased instruction hours improve the performance of all students? Using PISA scores of students in ninth grade, we analyse the effect of a German education reform that increased weekly instruction hours by two hours (6.5 percent) overalmost five years. In the additional time, students are...

This paper provides evidence of a novel facet of peer effects by showing how peer personality affects educational achievement. We exploit random assignment of students to university sections and find that students perform better in the presence of more persistent peers and more risk-averse...
