Platform Mergers: Lessons from a Case in the Digital TV Market*
研究了法国竞争管理局对电视频道广播服务合并的批准与广告销售服务合并的禁止，指出忽视平台双边互动可能导致意外结果。
We contribute to the analysis of mergers in two‐sided markets, in which a platform provides its service for free on one side but obtains all its revenues from the other. A structural model allowing for multi‐homing of advertisers is developed to assess a decision of the French competition authority, which approves the merger of the broadcasting services of TV channels but prohibits the merger of their advertising sales services through a behavioral remedy. We show that ignoring the interaction between the two sides of platforms in designing competition or regulatory policy can result in unexpected outcomes.
