Since the seminal contribution of Jackson and Wolinsky (J Econ Theory 71(1):44–74, 1996) it has been widely acknowledged that the formation of social networks exhibits a general conflict between individual strategic behavior and collective outcome. What has not been studied systematically are the sources of inefficiency. We approach this omission by analyzing the role of positive...

Certain estimation problems involving the covariance matrix in large dimensions are considered. Due to the breakdown of finite-dimensional asymptotic theory when the dimension is not negligible with respect to the sample size, it is necessary to resort to an alternative framework known as large-dimensional asymptotics. Recently, an estimator of the eigenvalues of the population...

These days, it is common practice to base inference about the coefficients in a hetoskedastic linear model on the ordinary least squares estimator in conjunction with using heteroskedasticity consistent standard errors. Even when the true form of heteroskedasticity is unknown, heteroskedasticity consistent standard errors can also used to base valid inference on a weighted least...

In 2014 the Swiss Upper House introduced an electronic voting system, which would make it easier to monitor the voting behavior of its legislators. In this system, individual decisions on specific exogenously defined vote types are published automatically, while all other votes are not publicly disclosed. The present paper uses this institutional change to determine, in a quasi-...

Das Interesse an der Verteilung von Einkommen und Vermögen ist in jüngster Zeit wieder neu entbrannt. Nicht zuletzt, weil nach vielen Jahren der Stabilität die Ungleichheit in vielen Ländern wieder zunimmt. Auch in der Schweiz geniesst die Frage nach der Einkommens- und Vermögensverteilung in der öffentlichen und politischen Diskussion grosse Aufmerksamkeit. Die Analyse über die...

This paper investigates how the peer gender composition in university affects students' major choices and labor market outcomes. Women who are randomly assigned to more female peers become less likely to choose male-dominated majors, they end up in jobs where they work fewer hours and their wage grows at a slower rate. Men become more likely to choose male-dominated majors after...

This paper empirically examines the business-stealing effect of store entry in the Swiss grocery retail industry. A uniquely spatially detailed dataset of all Swiss retail stores and residents is constructed, that captures important drivers of demand and competition with great detail. I employ Entropy Balancing to control for systematic differences across local markets and provide...
