This study analyses whether the Swedish school choice reform, enacted in 1992, had different effects on students from different socio-economic backgrounds. We use detailed geographical data on students' and schools' locations to construct measures of the degree of potential choice. This allows...

This paper presents a methodology to identify net demand shocks as well as wage rigidities in heterogeneous labor markets on the basis of nonparametric regression. We show how this approach can be used to make suggestions for immigration policy in economies with labor market rigidities. In an...

We study the role of privacy in the market for mobile applications. For such programs used with smartphones and tablet PCs a very important market has emerged. Yet, neither the role of privacy on that market is well understood, nor do we have empirical evidence regarding its role therein. We...

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...

Studies on the underlying mechanisms of social mobility commonly find that half of the intergenerational earnings persistence remains unexplained. Focusing on the phenomenon of overqualification, this study examines a transmission channel that might operate beyond the mechanisms previously...

Peer influence through word-of-mouth (WOM) plays an important role in many information systems but identification of causal effects is challenging. We identify causal WOM effects in the empirical setting of game adoption in a social network for gamers by exploiting differences in individuals'...

While private actions for damages against price-cartels by direct and indirect customers receive much attention, it is largely unresolved to what extent other groups that are negatively affected may claim compensation. This paper focuses on probably the most important one: suppliers to a...

In the past years Chinese firms increased their spending on R&D substantially and worked on achieving a higher quality level of R&D. We analyze whether different R&D activities show a positive influence on total factor productivity (TFP) for firms of different ownership types and across two time...
