Asymmetric Platform Oligopoly
研究了一个非对称平台寡头模型，分析平台如何通过设定参与费来管理用户接入，并探讨了平台进入、质量变化和兼容性程度的影响。
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. We explore the effects of platform entry, a change of incumbent platforms' quality under free entry, and the degree of compatibility. We show how the analysis can be extended to partial user participation.
