agents are myopic best responders. We develop a new network measure, the contagion threshold, that determines when a p … show that a p-dominant action spreads to the whole network whenever the contagion threshold of that network is greater or … the long run. This result implies that targeted contagion, a network-wide diffusion of actions initiated by targeting …

I study information diffusion in a social network where a third party can control the precision of information as well … each other through links in a social network. The designer relies on this word-of-mouth communication channel to diffuse …

We combine network formation and information transmission in a simple model and predict that people reveal less …

We then allow for endogenous … costs, the monocentric network with one aggregator connecting to all other agents as transmitters on a tree graph is the …

We study the diffusion of a true and a false opinion (the rumor) in a social network. Upon hearing an opinion …

This paper considers a population of agents that are engaged in a listening network. The agents wish to match their … neighbors in the network. I derive a closed expression for the (interim) social welfare loss that depends on the initial … information structure and on the possible pieces of information that can be gathered under the network.
