In this chapter, I provide an overview of research on social networks and their role in shaping behavior and economic … outcomes. I include discussion of empirical and theoretical analyses of the role of social networks in markets and exchange …, models of network formation, models for the statistical analysis of social networks, as well as community detection. …

On the contrary, the economics approach is very precise in explaining why networks emerge but …
