Organizing Distribution Channels for Information Goods on the Internet
研究内容提供商如何通过互联网分销信息商品，发现只有在接入市场充分竞争时他们才偏好互联网渠道；同时维持直销渠道可改变均衡，使互联网渠道始终有利。
Rapid technological developments and deregulation of the telecommunications industry have changed the way in which content providers distribute and price their goods and services. Instead of selling a bundle of content and access through proprietary networks, these firms are shifting their distribution channels to the Internet. In this new setting, the content and Internet service providers find themselves in a relationship that is simultaneously cooperative and competitive. We find that proprietary content providers prefer the Internet channels to direct channels only if the access market is sufficiently competitive. Furthermore, maintaining a direct channel in addition to the Internet channels changes the equilibrium enough that the proprietary content providers prefer having the Internet channels, regardless of the level of competition in the access market. Telecommunications technology developments uniformly increase content providers' profit. On the other hand, the technology impact on Internet service provider profits is nonmonotonic: Their profits may increase or decrease as a result of lower telecommunication costs. While initially the ISP profit increases as more customers are drawn to the Internet, it eventually decreases as the spatial competition becomes more intense. We also show that proprietary content providers should benefit from having some free content available at the Internet service providers' sites to induce more customers to join the Internet.
