Asymmetric Platform Oligopoly

open access: yesThe RAND Journal of Economics, EarlyView.
ABSTRACT We propose a tractable model of asymmetric platform oligopoly with logit demand in which users from two distinct groups are subject to within‐group and cross‐group network effects and decide which platform to join. We characterize the equilibrium when platforms manage user access by setting participation fees for each user group.
