In this article, we analyze whether non-native speakers in the classroom affect the educational achievement and social integration of migrant and native students. In contrast to previous studies, which mainly examine the effect of the share of immigrant pupils, we focus on language heterogeneity...

Population diversity arising from international migration does not only affect the labor market, but also its training ground – the classroom. While the economics literature studies the large and persistent achievement gap between native and foreign origin students, surprisingly little is...

This study investigates whether foreign origin teachers causally affect their students language skills in secondary school. Exploring within-student variation in assignment to teachers, I find that teachers who are immigrants or descendants of immigrants significantly increase the reading...

This study is the first empirical analysis to identify the causal effect of a separate preparatory language learning class on the academic success of newly immigrated primary school-aged children in comparison to their direct integration into regular classrooms. Employing unique administrative...

We use a newly available measure of linguistic distance developed by the German Max Planck Institute for Evolutionary Anthropology to explain heterogeneity in language skills of immigrants. This measure is based on an automatical algorithm comparing pronunciation and vocabulary of language...

There are various degrees of similarity between the languages of different immigrants and the language of their destination country. This linguistic distance is an obstacle to the acquisition of a language, which leads to large differences in the attainments of the language skills necessary for...
