Abstract

In this paper we relate a particular form of social interactions, i.e. peer group influences, to the structure of the network from which they originate. Using an extremely detailed dataset on friendship relationships between students from U.S. school, we find evidence suggesting that the topology of the networks of social contacts among teenagers might be an important actor in shaping their education achievement.

Keywords: Centrality measures, peer influence, network structure, directed and undirected networks, education
