Abstract
We study the problem of spreading a particular behavior among agents located in a random social network In each period of time neighboring agents interact strategically playing a 2 × 2 coordination game Assuming myopic bestresponse dynamics we show that there exists a threshold for the degree of risk dominance of an action such that below that threshold contagion of the action occurs This threshold depends on the connectivity distribution of the network Based on this we show that the wellknown scalefree networks do not always properly support this type of contagion which is better accomplished by more intermediate variance networks
