Regulation and the Vertically Integrated Firm: The Case of RBOC Entry into Interlata Long Distance.

Congress is considering telecommunications reform legislation that would allow the Regional Bell Operating Companies (RBOCs) to enter the interLATA long-distance market. A concern is that a vertically-integrated RBOC would be able to discriminate against its rivals. A proposed remedy would require the RBOCs to reduce their access market share as a precondition to interLATA entry. We show formally that such a precondition likely contributes to higher long-distance prices and enhances the risk of discrimination. Furthermore, the lower the share of access profits retained by an RBOC, the weaker are its incentives to lower long-distance prices. Copyright 1995 by Kluwer Academic Publishers
