We examine how three different communication processes operating through social networks are affected by homophily … on repeated averaging of neighbors' information and Markovian diffusion processes such as the Google random surfer model … friendship networks from the Adolescent Health dataset. …

to international travel, as indicated by centrality in air travel networks and tourist numbers is strongly associated …

The novelty of our model is to combine models of collective action on networks with models of social learning. Agents …

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 …

networks for which there is a convergence of beliefs. Finally, we survey some recent structural results on the speed of …

We analyze binary choice models in communication networks, in which both, the formation of links in the network as well … networks, where agents choose their strategies - actions and links - according to a perturbed best response update rule. We …

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 …
