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...

We recently showed that obesity can spread socially from person to person in adults (Christakis and Fowler 2007). A natural question to ask is whether or not these results generalize to a population of adolescents. Three separate teams of researchers have analyzed the National Longitudinal Study...

Previous research has indicated that higher levels of social interactions, or greater social capital, tend to create higher levels of civic engagement and social trust. We used a large, nationally representative longitudinal survey of youth to examine the relationship between social capital, as...
