The spread of innovations in social networks

Andrea Montanari, Amin Saberi · 2010 · Proceedings of the National Academy of Sciences

Summary. This paper examines how network structure affects the speed at which innovations spread when people make strategic choices between competing alternatives. Using coordination game models, the authors find that innovations spread much more slowly on highly connected networks with long-range links than on low-dimensional networks based on geographic proximity. Their results contradict predictions from epidemic models commonly used to study innovation diffusion.
