本文提出了一种平台侵占模型，其中平台不仅充当消费者和第三方卖家之间的中介，而且还销售其第一方产品。当侵犯时，平台会在公平和有偏见的搜索引擎之间进行选择。在公平搜索下，所有产品出现在搜索结果中的可能性相同，而在偏见搜索下，第一方产品更有可能出现。有偏见的侵占使得平台向卖家收取较低的佣金，从而导致均衡价格较低，从而吸引更多的消费者。增加消费者参与可以通过间接网络外部性提高卖家参与。
This paper presents a model of platform encroachment, in which a platform not only acts as an intermediary between consumers and third-party sellers, but also sells its first-party products. When encroaching, the platform chooses between fair and biased search engines. Under the fair search, all products are equally likely to appear in search results, whereas the first-party product is more likely to appear under biased search. Biased encroachment makes the platform impose a lower commission on sellers, which leads to a lower equilibrium price which consequently attracts more consumers. Increased consumer participation can raise seller participation through indirect network externalities.
