主   题：Mergers between On-Demand Service Platforms: The Impact on Consumer Surplus and Labor Welfare

主讲人：王鑫 西南财经大学工商管理学院大数据研究院教授

主持人：肖诗虹 复旦大学管理学院副教授

Abstract: We study the impact of mergers between on-demand service platforms on consumer surplus and labor welfare. On an on-demand service platform, more agents benefit customers, and more customers generate higher earnings for agents, which is referred to as the cross-side network effect. We build a game-theoretical model to analyze the impact of a merger between two platforms in the presence of the cross-side network effect. While a merger reduces competition, the merged platform can pool customers and agents together and improve matching; moreover, the merger can amplify the cross-side network effect and thus moderate the merged firm’s pricing power. When the cross-side network effect becomes strong enough, some of the benefits from pooling may be left to customers and agents. In this case, a merger can make merging firms, customers, and agents all better off, resulting in a win-win-win outcome.
