Education is key to the structural integration of immigrants and their children. While research indicates that educational inequalities by migration background are a serious issue, relatively little is known about when, how and why they develop. The current paper adds to the literature by investigating to what extent achievement gaps by migration background develop during the primary school period. Drawing on data from a national longitudinal study of children in Ireland (N = 7577) and using structural equation modelling, it presents a path model of host language achievement. The results indicate that a large part of the disadvantages in English language achievement by migration background during primary school could be attributed to achievement gaps that already existed before school. Moreover, given earlier achievement, the effect of having a migration background was often insignificant or even positive, suggesting that disparities remain relatively stable or even decrease during the period of formal schooling.

This study examines within- and cross-country trends and differences in marital sorting by education in Europe. Unlike previous research on assortative mating, our study focuses on the outcomes of the partner search process. We investigate how variations in (a) structural opportunities (educational composition of potential partners) and (b) assortative mating (non-random matching by education) have shaped trends and differences in educational sorting outcomes. Using vital statistics data on all marriages contracted from 2000 to 2020 in Sweden, the Czech Republic, and Italy, we decompose trends and differences in educational sorting outcomes into these two components. Within countries, trends in educational homogamy and hypogamy have been stable or increasing while hypergamy has declined. However, the drivers of these trends varied across countries. For example, in Sweden, shifts in assortative mating and structural opportunities led to more marriages between equally educated spouses, while in Italy, the rise in homogamy stems solely from changes in assortative mating. Within each year, homogamy and heterogamy levels varied between countries. Our findings demonstrate that these cross-country differences can be primarily attributed to variations in assortative mating rather than in opportunity structures. This study adds to recent research studying the structural causes of trends in sorting outcomes. [ABSTRACT FROM AUTHOR]

Graduate and doctoral schools around the world struggle to shorten the long time to degree and to prevent high dropout rates. While most of previous research studied individual determinants of PhD completion, we analyze the impact of two structural reforms of the doctoral program on thesis completion at a selective European graduate school. Exploiting a unique PhD dataset covering 30 entry cohorts, we identify reform effects on PhD outcomes using an interrupted time-series regression design. We find that the first reform improved timely completion rates by between 10 and 15 percentage points (according to the specific outcome), whereas the second reform increased completion rates by between 9 and 20 percentage points. Additionally, each reform reduced dropout rates by 7 percentage points. The results are robust to various sensitivity checks. At the end, we discuss lessons learned for those in charge of graduate schools and/or PhD programs.
