So, I’ll focus on how the separation requirement might work for Amazon Marketplace. The costs and benefits of a separation requirement have to be evaluated on a fairly narrow case-by-case basis. In the case of Amazon’s Marketplace, the danger of the separation requirement for vendors is the potential loss of Amazon’s customer base. A regulator or a court would have to supervise the platform separation requirement on an on-going basis. Yet many of them, 300,000 new ones per year, choose to sell on Amazon Marketplace.
