In 1999, a reform of education was implemented in Poland, which added one year to the shortest available educational path, leading to the acquisition of basic vocational education. In the new system, students choosing this path acquire one more year of general education, which, according to the...

This study aims to identify the main determinants of student performance in reading and maths across eight European Union countries (Austria, Croatia, Germany, Hungary, Italy, Portugal, Slovakia, and Slovenia). Based on student-level data from the OECD’s PISA 2018 survey and by means of the...

Using census data on three cohorts of 5th grade Italian students we investigate how the ordinal rank in the within-school age distribution affects the probability of being bullied. Identification is achieved by exploiting within-school between-cohort variation in the age composition of different...

This paper introduces an empirical strategy to estimate dynamic treatment effects in randomized trials that provide treatment in multiple stages and in which various noncompliance problems arise such as attrition and selective transitions between treatment and control groups. Our approach is...

Social distancing requirements associated with COVID-19 (coronavirus) have led to school closures. In mid-April, the United Nations Educational, Scientific and Cultural Organization reported that 192 countries had closed all schools and universities, affecting more than 90 percent of the...

We use administrative panel data on about a quarter of a million students in the German state of Hesse to estimate the causal effect of class size on school tracking outcomes after elementary school. Our identification strategy relies on the quasi-random assignment of students to different class...

We examine the relationship between wealth and health through prominent growth indicators and cognitive ability. Cognitive ability is represented by nutritional status. In this study, the proxy variable for nutritional status is BMI since there is a strong relationship between cognitive ability...

The SEED schools, which combine a "No Excuses'' charter model with a five-day-a-week boarding program, are America's only urban public boarding schools for the poor. We provide the first causal estimate of the impact of attending SEED schools on academic achievement, with the goal of...

Using exogenous secondary school assignments to remove self-selection bias to schools and peers within schools, I credibly estimate both (1) the effect of attending schools with higher-achieving peers, and (2) the direct effect of short-run peer quality improvements within schools, on the same...

This study examines the variation in educational outcomes across and within countries using the TIMSS mathematics tests. It documents the wide cross-country variation in the level and dispersion of test scores. Countries with the highest test scores are those with the least inequality in scores,...
