摘要：
This paper develops a model to examine the formation of influencer networks in user-generated content markets. Unlike previous research, we find that every strict equilibrium network exhibits a nested, upward-linking structure where multiple levels of influencers can coexist. Moreover, across a broad range of parameters, all payoff dominant strict equilibria conform to the law of the vital few: regardless of the population size, a small but significant group of players provides all content. We also establish a link between efficiency and equilibrium, and shows that all efficient strategy profiles are strict equilibria of an auxiliary game with larger benefit parameters. For sufficiently large populations, a single nested upward-linking network connecting all players can emerge, despite potentially polarized tastes over content categories.
