Behaviors and information often spread via person-to-person diffusion. This paper highlights how diffusion processes can facilitate coordination. I study contagion in a discrete network with Bayesian players. In addition to characterizing the extent and rate of adoption, we uncover a new effect:...

I study learning about an innovation with costly information acquisition and knowledge sharing through a network. The network structure and initial beliefs jointly determine long-run adoption behavior. Networks that share information efficiently converge on a consensus more quickly but are prone...
