Influential Opinion Leaders

Abstract

We present a two-stage coordination game in which early choices of experts with special interests are observed by followers who move in the second stage. We show that the equilibrium outcome is biased toward the experts' interests even though followers know the distribution of expert interests and account for it when evaluating observed experts' actions. Expert influence is fully decentralized in the sense that each individual expert has a negligible impact. The bias in favor of experts results from a social learning effect that is multiplied through a coordination motive. We show that the total effect can be large even if the direct social learning effect is small. We apply our results to the diffusion of products with network externalities and the onset of social movements.
