Integration and Independent Innovation on a Network
分析电信网络中垄断者与独立创新者之间的激励冲突，指出垄断者可能阻碍创新，并探讨隔离、平价定价等解决方案的可行性，对电信政策与反垄断有参考价值。
Physical telecom networks are costly and few, traditionally to the point of monopoly. Innovation thrives with many independent minds. So one might hope independent innovators, not only its proprietor M, can offer innovative services on a network, as has been true on the Internet. This issue is central in telecom policy; it also arises elsewhere, including complaints about Microsoft. I try to expound the following key points. Often an unregulated M has ex ante incentives to organize service innovation efficiently. But this incentive breaks down ex post as M can extract an independent J’s quasi-rents (Farrell and Michael Katz 2000). Even ex ante, the one monopoly rent theorem (Ward Bowman 1957) fails when M’s bottleneck access business is more regulated than its competitive services (e.g., Jean-Jacques Laffont and Jean Tirole 2000). This tempts M to sabotage J’s innovations. Quarantining M from the service sector solves these problems, but excludes the firm with (often) the best opportunities and the strongest incentives to innovate. Parity pricing or ECPR (Robert Willig 1979) purports to get the best of both worlds (BoBW). But it seems so hard to implement in innovation markets that one might construe ECPR analysis as reductio ad absurdum for BoBW.
