Balancing Variety and Quality: Examining the Impact of Benefit‐Linked Cross‐Subsidization on Multisided Platforms

open access: yesJournal of Management Studies, Volume 62, Issue 4, Page 1717-1746, June 2025.
Abstract Multisided platforms face a fundamental trade‐off: should they ease entry for a larger number of providers of complementary products or services (complementors) to join the platform and benefit from cross‐side network externalities, or should they limit entry to maintain complementors’ incentives to provide high‐quality offerings?
