When contributing content on large online platforms, producers of user-generated content have to decide where to contribute. On a complex and dynamic platform like wikipedia, this decision is expected to depend on the way the content is organized. We analyse whether the hyperlinks on Wikipedia...

I quantify spillovers of attention in a network of content pages, which is challenging, because such networks form endogenously. I exploit exogenous variation in the article network of German Wikipedia to circumvent this problem. Wikipedia prominently advertises one featured article on its main...

In this paper we estimate the effects of college education on cognitive abilities and health exploiting exogenous variation in college availability and student loan regulations. By means of semiparametric local instrumental variables techniques we estimate marginal treatment effects in an...

Theoretically, there are several reasons to expect education to have a positive effect on health, and empirical research suggests that education can be an important health determinant. However, it has not yet been established whether education and health are indeed causally-related, and the...

We analyze the effect of education on wages using German Socio-Economic Panel data and regional variation in mandatory years of schooling and the supply of schools. This allows us to estimate more than one local average treatment effect and heterogeneous effects for different groups of...

The Bologna Process aimed at harmonizing European higher education systems and at increasing their efficiency. This paper analyzes impacts of the Bologna Reform for Germany by using unique micro data from Humboldt-Universität zu Berlin (HU). We estimate treatment effects on the probability to...

In this paper, we investigate sibling correlations in educational outcomes, which serve as a broad measure of the importance of family and community background. Making use of rich longitudinal survey and register data for Denmark, our main aim is to identify the parental background...

The spell-based nature of the National Educational Panel Study poses some challenges for analyzing training participation rates across waves. Raw training participation rates of each wave using courses compiled in the SpCourses data set and in the SpEmp data set differ by up to 75 percent across...

Occupational mismatch is a wide-spread phenomenon among immigrants in many European countries. Mismatch, predominantly measured in terms of education, is often regarded as a waste of human capital. Such discussions, however, ignore the imperfect comparability of international educational degrees...

The previous literature has shown that children who enter school at a more advanced age outperform their younger classmates on competency tests taken between kindergarten and Grade 10. This study analyzes whether these effects of school starting age continue into adulthood. Based on data on math...
