We survey the literature on the economic consequences of the structure of social networks. We develop a taxonomy of … "macro" and "micro" characteristics of social interaction networks and discuss both the theoretical and empirical findings … concerning the role of those characteristics in determining learning, diffusion, decisions, and resulting behaviors. We also …

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 …

characterizes the topology of competing (and potentially overlapping) diffusion paths. Sellers indirectly appropriate profits over … diffusion and confer monopoly power. Links that bridge distinct classes are redundant for diffusion and generate competition … among sellers. In dense networks, competition limits the scope of indirect appropriability and intellectual property rights …
