Platform Governance
研究了亚马逊、爱彼迎等交易中介平台如何设计非价格治理规则，并分析其激励是否有利于社会福利，发现平台治理可能扭曲卖家竞争程度。
Platforms that intermediate trades—such as Amazon, Airbnb, and eBay—play a regulatory role in deciding how to govern the marketplaces they create. We propose a framework to analyze a platform’s nonprice governance design and its incentive to act in a welfare-enhancing manner. We show that the platform’s governance design can be distorted toward inducing insufficient or excessive seller competition, depending on the nature of the fee instrument employed by the platform. These results are illustrated with micro-founded applications to a platform’s control over seller entry, information provision and recommendations, quality standards, and search-design choices.
