Group Hug: Platform Competition With User-Groups [PDF]
SSRN Electronic Journal, 2018 We consider platform competition for small users and a user group. One platform enjoys a quality advantage and the other benefits from favorable beliefs. We study whether the group mitigates the users’ coordination problem—i.e., joining a low-quality platform because they believe that other users would do the same.
