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 …

Network externalities spur the growth of networks and the adoption of network goods in two ways. First, they make it …—which, for small networks, can amount to a large relative increase. 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 …

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. …

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

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 …

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 …
