An Empirical Model for Strategic Network Formation

Christakis, Nicholas A. - 2010

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...
