Networks in Economics: Theory, Econometrics, and Policy Implications draws on the latest findings in economics, sociology, physics, computer science and mathematics, providing an empirical review of social network analysis, and their regularities. It discusses random graph-based models as well as strategic models of network formation. The three parts of the book, theory, empirics and policy, are presented in a consistent and interdependent framework. This book supports students, researchers and practitioners, helping them to understand outcomes and behaviors in networked societies, and to be able to evaluate real world policy instruments in this context.

Chih-Sheng Hsieh is Assistant Professor at The Chinese University of Hong Kong, China. His research interests span over labor economics, health economics, and social networks. In particular, he works on endogenous selection issues inherited in social interaction studies, and empirical network formation to accommodate important features from observed network data, such as homophily in characteristics, behaviors, as well as link dependence.
