This chapter examines the effects of network topology on the diffusion of behaviors. A key empirical question is, what is the expected length of time for a network to “switch over” from the old behavior to the new? It uncovers conditions on network topology the decision process that, surprisingly, bound the expected waiting time for diffusion to occur from above, independently of the size of the network.

Keywords: network topology; behaviors; decision process; diffusion
