Communication Filters/Networks/Filter/Communication/Bloch/Demange/Kranton: (…) networks can serve as a filter and aid communication. We contrast the network outcomes to a situation where agents can communicate to everyone simultaneously.
>Public Broadcast Model: In this “public broadcast model”, there are only two equilibrium outcomes: one with full communication and one with no communication. Full communication arises if and only if there are sufficiently few biased agents in the population
>Network Model: The network can replicate the full communication outcome when biased agents are evenly distributed in the network. The network, however, can also allow partial communication when no communication occurs in the public broadcast model. In a network, agents can block messages that originate in parts of the network that contain many biased agents. The messages that do circulate contain sufficient information for agents to take them into account when voting on the collective decision.
Strategy/Communication: (…) biased agents wishing to influence a population could be better off limiting their numbers. As unbiased agents are strategic, they block the transmission of opinions that originate in a part of the network that contains many biased agents. Hence, it can serve biased agents to limit their numbers and to spread themselves throughout the network, so as to maximize message transmission. >Misinformation/Economic theories, >Rumors/Kranton.
