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 …, learning and diffusion, and network games. I also include some background on social network characteristics and measurements …
