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. …

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. …

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 …

on percolation dynamics. The model combines the concept of increasing returns to adoption with information diffusion … among consumers within social networks. The main contribution of the model is that it replicates the three stages of the … product lifecycle as an outcome of a single elementary process. The model also replicates the S-shaped diffusion curve and the …

social networks act as substitutes in the diffusion of knowledge. …Although prior empirical research has established an association between science and the widespread diffusion of … investigates whether the knowledge diffusion associated with science-based innovation stems from the norm of openness and …

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

In this paper, we propose an individual-level approach to diffusion and growth models. By , we refer to the unit of …

in a society, the underlying proclivities of various types for adoption or infection, as well as how each type interacts … with its own type. In particular, we show that homophily can facilitate diffusion from a small initial seed of adopters. …
