越来越多的中间商（如亚马逊、苹果的Appstore和沃尔玛）在自己的市场上充当经销商。我们建立了一个双重市场和经销商中介的模型，以探讨这种做法的影响，并呼吁禁止它，考虑到中介的最佳模式选择。我们的分析表明，即使在允许第三方卖家进行创新之后，彻底的禁令往往会以牺牲消费者剩余或福利为代价，使第三方卖家受益。我们的研究表明，限制对高度创新的第三方产品的模仿并防止买家转向中介自己的产品的政策，而不是彻底禁止，将导致更可取的结果。
A growing number of intermediaries (e.g. Amazon, Apple's Appstore, and Walmart) act as resellers on their own marketplaces. We build a model of dual marketplace and reseller intermediation to explore the implications of this practice, and the call to ban it, taking into account an intermediary's optimal choice of mode. Our analysis shows that an outright ban tends to benefit third-party sellers at the expense of consumer surplus or welfare, even after allowing for innovation by third-party sellers. Rather than an outright ban, we show that policies that limit the imitation of highly innovative third-party products and prevent steering of buyers to the intermediary's own products would lead to preferable outcomes.
