Peacetime military service has both positive and negative effects on human capital. While it depreciates academic abilities it also enhances non-cognitive skills. The net effect of conscription is hard to identify due to issues of self-selection, endogenous timing and omitted variables bias. We...

Despite extensive literature on peer effects, the role of peers on personality skill development remains poorly understood. We fill this gap by investigating the effects of having disadvantaged primary school peers, generated by random classroom assignment and parental migration for employment....

A dynamic discrete choice model is set up to estimate the effects of grade retention in high school, both in the short-run (end-of-year evaluation) and in the long-run (drop-out and delay). In contrast to other evaluation approaches, this model captures essential treatment heterogeneity and...

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...

To study the causal impact of smartphone use on academic performance, we collected - for the first time worldwide - longitudinal data on students' smartphone use and educational performance. For three consecutive years we surveyed all students attending classes in eleven different study...

We examine the educational spillover effects of migrant students on local students' academic achievement in public middle schools in urban China. The identification of peer effects relies on idiosyncratic variation in the proportion of migrant students across classes within schools. We find that...

In this paper we study the allocation of time devoted to informal learning and education, i.e. those activities carried out during leisure time and outside formal education courses which boost individuals’ human and social capital. For immigrants the private investment in these activities is...

After a decade of correlational research, this study attempts to measure the causal impact of (general) smartphone use on educational performance. To this end, we merge survey data on general smartphone use, exogenous predictors of this use, and other drivers of academic success with the exam...
