Coordination and Lock-In: Competition with Switching Costs and Network Effects

Farrell, Joseph; Klemperer, Paul - C.E.P.R. Discussion Papers - 2006

Switching costs and network effects bind customers to vendors if products are incompatible, locking customers or even markets in to early choices. Lock-in hinders customers from changing suppliers in response to (predictable or unpredictable) changes in efficiency, and gives vendors lucrative ex...

Calling Circles: Network Competition with Non-Uniform Calling Patterns

Hoernig, Steffen; Inderst, Roman; Valletti, Tommaso - C.E.P.R. Discussion Papers - 2010

We introduce a flexible model of telecommunications network competition with non-uniform calling patterns, which account for the fact that customers tend to make most calls to a small subset of people. Equilibrium call prices are distorted away from marginal cost, and competitive intensity is...

Competition Between Multiple Asymmetric Networks: Theory and Applications

Hoernig, Steffen - C.E.P.R. Discussion Papers - 2010

We present a tractable model of competition between an arbitrary number of interconnected communications networks in the presence of tariff-mediated network externalities, call externalities, and cost and market share asymmetries. On the theory side, we provide a criterion for stability in...

Tariff-Mediated Network Externalities: Is Regulatory Intervention Any Good?

Hoernig, Steffen - C.E.P.R. Discussion Papers - 2008

Mobile phone networks' practice of charging higher prices for off-net than for on-net calls has been pinpointed as the source of two competition problems: underprovision of calls and permanent disadvantages for small networks. We consider these allegations and four different remedies: limiting...

Asymmetric Broadband Wholesale Regulation

Hoernig, Steffen - C.E.P.R. Discussion Papers - 2011

existing access regulation is based on a single essential network. We show that continued asymmetric access regulation of one … network does not control sufficiently for market power and benefits the unregulated network, and that symmetric regulation … would lead to higher consumer surplus. Furthermore, the whole setup of access regulation may not be viable in the long run …
