Angel Lopez (Public-Private Sector Research Center, IESE Business School) and Patrick Rey (Toulouse School of Economics) explain Foreclosing Competition through Access Charges and Price Discrimination.
ABSTRACT: This article analyzes competition between two asymmetric networks, an incumbent and a new entrant. Networks compete in non-linear tariffs and may charge different prices for on-net and offnet calls. Departing from cost-based access pricing allows the incumbent to foreclose the market in a pro table way. If the incumbent bene ts from customer inertia, then it has an incentive to insist in the highest possible access markup even if access charges are reciprocal and even in the absence of actual switching costs. If instead the entrant benefits from customer activism, then foreclosure is profitable only when switching costs are large enough.
