Online social networks, such as Facebook, disclose an unprecedented volume of personal information amplifying the occasions for social comparisons, which can be a cause of frustration. We test the hypothesis that the use of social networking sites (SNS) increases social comparisons as proxied by...

This research examines the strength of people's ties with close neighbours and the sensitivity thereof to changes in residential mobility, access to modes of public and private transport, and changes in the availability of modern communications technologies using the German Socio-economic Panel...

This paper examines to what extent marital sorting affects cross-sectional earnings inequality in Germany over the past three decades, while explicitly taking into account labor supply choices. Using rich micro data, the observed distribution of couples' earnings is compared to a counterfactual...

This paper examines to what extent non-random sorting of spouses affects earnings inequality while explicitly disentangling effects from increasing assortativeness in couple formation from changing patterns of couples' labor supply behavior. Using German micro data, earnings distributions of...

We analyze the effects of three alternative proposals to reform the taxation of families relative to the current German system of joint taxation of couples and child allowances: a French-type family splitting and two full family splitting proposals. The empirical analysis of the effects of these...

The tertiarization, or perhaps more accurately, the deindustrialization of the economy has left deep scars on cities. It is evident not only in the industrial wastelands and empty factory buildings scattered throughout the urban landscape, but also in the income and social structures of cities....

Drawing on the distinction between envy and signaling effects in income comparison, this paper uses 307,465 observations for subjective well-being and its covariates from Germany, 1990-2009, to study whether the nature of income comparison has changed in the process of economic development, and...

We study a dynamic model of opinion formation in social networks. In our model, boundedly rational agents update opinions by averaging over their neighbors' expressed opinions, but may misrepresent their own opinion by conforming or counter-conforming with their neighbors. We show that an...

We investigate the role of manipulation in a model of opinion formation. Agents repeatedly communicate with their neighbors in the social network, can exert effort to manipulate the trust of others, and update their opinions about some common issue by taking weighted averages of neighbors'...

We analyze delinquent networks of adolescents in the United States. We develop a dynamic network formation model showing who the key player is, i.e. the criminal who once removed generates the highest possible reduction in aggregate crime level. We then structurally estimate our model using data...
