In recent decades, changes in parents' attitudes towards the importance of spending time with children to optimise their future behaviour and cognitive development have greatly affected patterns of time allocation among both working and non-working parents in all developed countries. We compare...

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'...

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...

In this study we investigate the minimum wage (MW) effects for a German sub-construction sector where the MW bites extraordinary hard by international standards. Within a quasiexperiment we estimate the Quantile Treatment Effects of the MW on the conditional and unconditional distribution of...

On Wikipedia, the largest online encyclopedia, editors who contribute to the same articles and exchange comments on articles' talk pages work in collaborative manner engaging in communication about their work. Thus they can be considered as peers who are likely to influence each other. In this...
