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

Under the proposed information mechanism, consumers share their initial information with the members of their network … characterizing how many different pieces of information a network is likely to contain. This informativeness is crucial for the … results are robust to the introduction of sequential search and network segregation, but an increase in segregation decreases …

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

A non-cooperative model of network formation is developed. Agents form links with others based on the cost of the link …

Moreover, we contrast equilibrium …

We develop a dynamic framework of strategic information transmission through cheap talk in a social network. Privately … their neighbors in the network.
