This paper studies competition in the German market for mobile telecommunications, motivated by recent suggestions that T-Mobile and Vodafone possess a position of collective dominance. Allegedly, their position of joint dominance is secured through a combination of first-mover advantages and...

This paper estimates demand elasticities for the Turkish mobile telecommunication market. In contrast to most other studies, firm level data is used to estimate dynamic panel data models including instrumental variable techniques. Both short- and long-run elasticities are calculated, yielding a...

This paper explores how consumers react towards price differentiation between on-net and off-net calls in mobile telecommunications - a pricing policy that is common in many mobile telecommunications markets. Based on a survey of 1044 students we demonstrate that some consumers may suffer from a...

This paper examines mobile termination fees and their regulation when networks are asymmetric in size. It is demonstrated that with consumer ignorance about the exact termination rates (a) a mobile network's termination rate is the higher the smaller the network's size (as measured through its...

This paper analyzes how competition works in mobile telecommuncations markets and, bases on this analysis, we discuss whether regulatory intervention in mobile telephone markets is justified from an economic perspective. Starting point of our analysis is the observation that an evaluation of...

This paper examines the consequences of introducing mobile number portability (MNP). As MNP allows consumers to keep their telephone number when switching providers, it reduces consumers' switching costs. However, MNP may also cause consumer ignorance if telephone numbers no longer identify...

Das vorliegende Papier beschreibt und analysiert die erfolgte Liberalisierung des Telekom-munikationssektors in Deutschland. Zu diesem Zweck werden die erfolgten Liberalisierungs-maßnahmen beschrieben und ihre Auswirkungen auf die verschiedenen Märkte analysiert. Während der Wettbewerb in den...

This paper provides a hedonic price analysis of mobile telephones for the German market. We have assembled data on 302 different handsets from 25 manufacturers over the period from May 1998 to November 2003. While volume has a negative effect on the price of a mobile handset, the number of...

This paper analyzes price elasticities in the Austrian market for mobile telecommunications services using data on firm specific tariffs. Both static and a dynamic panel data approaches lead to consistent results which provide evidence for a relatively elastic demand. Furthermore, some basic...

This paper analyses price elasticities in the Austrian market for mobile telecommunications services using data on firm specific tariffs in the period between January 1998 and March 2002. Dynamic panel data regressions are used to estimate short-run and long-run demand elasticities for business...
