We examine the spread of a disease or behavior through a social network. In particular, we analyze how infection rates … first- and second order stochastic dominance relationships of the degree distribution in order to compare infection rates … across different social networks. …

The paper examines individuals’ abilities to identify the highly central people in their social networks, where … centrality is defined by diffusion centrality (Banerjee, Chandrasekhar, Duflo, and Jackson, 2013), which characterizes a nodeâ …€™s influence in spreading information. It first show that diffusion centrality nests standard centrality measures – degree …

We consider the spread of a harmful state through a population divided into two groups. Interaction patterns capture the full spectrum of assortativity possibilities. We show that a central planner who aims for eradication optimally either divides equally the resources across groups, or...

Although an influence network is a crucial factor affecting diffusion processes, it is generally fixed or assumed to … follow some typical topologies in traditional diffusion research. The purpose of this study is to examine how innovation … diffusion is changed by different influence relationship structures existing among individuals. We introduce an extended version …

The difference between small, local, personal networks and … large, global, anonymous networks arises endogenously from our analysis. Fundamentally, the first type of networks is “tie …
