We study strategic transmission of rival information among individuals who have altruistic relations. Information sharing naturally takes the form of word-of-mouth communication. Yet, the social forces that promote communication can also undermine it. Contrary to conventional wisdom, larger social networks may spread information less, and better-connected individuals may receive less information. Therefore, when forming networks, individuals cluster into groups that share information and trust by limiting connections as a commitment to secrecy.
Keywords: Information transmission, communication, social networks, directed altruism, trust, secrecy, network formation
