This paper measures impacts of removing children from families investigated for abuse or neglect. We use removal tendencies of child protection investigators as an instrument. We focus on young children investigated before age six and find that removal significantly increases test scores and...

We look at the effect of school starting age on standardized test scores using data covering all grade four and grade eight students in Hungary. Instrumental variables estimates of the local average treatment effect suggest that children generally gain from starting school one year later and the...

While there is a big literature on the benefits of pre-school education, only little is known why kindergarten attendance improves later-life outcomes. This is partly because most studies analyze the effect of complete 2 years pre-school programs. In order to shed light into the black box of...

Grouping students by ability is a controversial issue, and its impacts are likely to depend on the type of tracking students are exposed to. This paper studies a reform that moved French schools from a rigorous tracking system, which assigned students to tracks with significantly different...

We estimate the nonlinear impact of class size on student achievement by exploiting regulations that cap class size at 20 pupils per class in kindergarten. Using student-level information from a previously unexploited large-scale census survey of kindergarten students, this study provides clear...

This paper examines the effects of skill advantages at age six on different types of parental investments, and long-run outcomes up to age 27. We exploit exogenous variation in skills due to school entry rules, combining 20 years of Chilean administrative records with a regression discontinuity...

We estimate the nonlinear impact of class size on student achievement by exploiting regulations that cap class size at 20 students per class in kindergarten. Based on student-level information from a previously unexploited and unique large-scale census survey of kindergarten students, this study...

Several studies have shown that body height is positively associated with educational attainment. In this paper, we investigate the mechanisms behind this relationship using data on German pre-teen students. We show that (i) taller children are more likely to enroll in ‘Gymnasium’, the most...

We examine whether parental and school investments reinforce or compensate for student performance. Our analysis exploits school-starting-age rules in 34 countries, capturing achievement variation that arises because younger children typically underperform their older peers. Parents respond to...

Learning outcomes among children play a major role in shaping up future individual earnings. Along with the demand side factors like parental income and education, supply side factors like school quality are important as well in shaping up learning outcomes. In the view of increasing preference...
