This paper studies whether structural properties of friendship networks affect individual outcomes in education. We first develop a model that shows that, at the Nash equilibrium, the outcome of each individual embedded in a network is proportional to her Katz-Bonacich centrality measure. This...

This paper studies whether conformism behavior affects individual outcomes in crime. We present a social network model of peer effects with ex-ante heterogeneous agents and show how conformism and deterrence affect criminal activities. We then bring the model to the data by using a very detailed...

This article aims to summarize the existing body of literature on social interactions and their effect on individual unemployment status. Two directions of the ongoing research are analyzed: the impact of social norms on unemployment and the importance of social networks in the job search...

This paper investigates opinion dynamics and social influence in directed communication networks. We study the theoretical properties of a boundedly rational model of opinion formation in which individuals aggregate the information they receive from their neighbors by using weights that are a...

In this paper we test the celebrated `Strength of weak ties' theory of Granovetter (1973). We test two hypotheses on the network structure in a data set of collaborating economists. While we find support for the hypothesis of transitivity of strong ties, we reject the hypothesis that weak ties...

Using novel information from the German Socio-Economic Panel for the period 1996-2011, we document that migrants with a German friend are more similar to natives than those without a local companion along several important dimensions, including engagement in social activities, concerns about the...

We develop a model where workers both choose their residential location (geographical space) and social interactions (social space). In equilibrium, we show under which condition the majority group resides close to the job center while the minority group lives far away from it. Even though the...

We develop a model where workers both choose their residential location (geographical space) and their social interactions (social space). In equilibrium, we show under which condition some individuals reside close to the job center while others live far away from it. Even though the two...

We develop a model where information about jobs is essentially obtained through friends and relatives, i.e. strong and weak ties. Workers commute to a business center to work and to interact with other people. We find that housing prices increase with the level of social interactions in the city...

This paper presents an heuristics of economic action in South Korea which is based on a qualitative study conducted on-site. It focuses on the idea of experience-near concepts - as introduced by Clifford Geertz - and is verbalised by the terms affiliation, indebtedness and mediation. The...
