On The Role of Access Charges Under Network Competition


Buehler, Stefan; Schmutzler, Armin (2005). On The Role of Access Charges Under Network Competition. Working paper series / Socioeconomic Institute No. 501, University of Zurich.

Abstract

We aim to clarify the role of access charges under two-way network competition, employing a reduced-form approach. Retaining the key features of specific network competition models but imposing less structure, we analyze the impact of changes in access charges on linear and non-linear retail prices. We derive su.cient conditions for usage fees to be increasing (and subscriber charges to be decreasing) in access charges. These conditions are shown to be satisfied only under rather restrictive assumptions on the demand for calls, suggesting that implementing collusion by inflating access charges is likely to be nonfeasible.
