This paper considers the semiparametric identification of endogenous and exogenous peer effects based on group size variation. We show that Lee (2006)'s linear-in-means model is generically identified, even when all members of the group are not observed. While unnecessary in general,...

Die Etablierung des Westlichen Maiswurzelbohrers (Diabrotica virgifera virgifera) stellt eine zentrale Herausforderung für die österreichische Maisproduktion dar. Eine aktive Regulierung ist unerlässlich, um weitere Schäden zu verhindern bzw. zu reduzieren. Die Umsetzung bzw. Nicht-Umsetzung...

In social and economic networks linked agents often share additional links in common. There are two competing explanations for this phenomenon. First, agents may have a structural taste for transitive links - the returns to linking may be higher if two agents share links in common. Second,...

We develop and analyze a tractable empirical model for strategic network formation that can be estimated with data from a single network at a single point in time. We model the network formation as a sequential process where in each period a single randomly selected pair of agents has the...

One of the motivations for establishing a European banking union was the desire to break the ties with between national regulators and domestic financial institutions in order to prevent regulatory capture. However, supervisory authority over the financial sector at the national level can also...

We study the social interaction of non-smokers and smokers as a sequential game, incorporating insights from social psychology and experimental economics into an economic model. Social norms affect human behavior such that non-smokers do not ask smokers to stop smoking and stay with them, even...
