Often, fi xed-line incumbents also own the largest mobile network. We consider the effect of this joint ownership on market outcomes. Our model predicts that while fixed-to-mobile call prices to the integrated mobile network are more efficient than under separation, those to rival mobile...

A model of competition between two interconnected cellular networks is presented which shows the effects of cellular termination charges on competition and market penetration in the cellular sector. We show that the determination of cellular termination charges is quite different to standard...

A new class of access pricing problems is analyzed in which upstream firms compete for customers and access to these customers is required by downstream markets. Using fixed-to-cellular calls as an example, a model is presented which shows that the determination of cellular termination charges...

The increasing usage of mobile communication and the declining demand for fixed line telephony in Europe make the analysis of substitutional effects between fixed and mobile networks a key aspect for future telecommunication regulation. Using a unique dataset which contains information on all 27...

This paper investigates the degree of fixed-mobile call substitution (FMCS). We use quarterly data from 2004 to mid 2010 on 16 mainly Western European countries. By applying dynamic panel data techniques, we are able to estimate short-and long-run elasticities. The own-price and cross-price...

WIK-Consult hat für das Bundesministerium für Digitales und Verkehr (BMDV) untersucht, welche Rahmenbedingungen den Ausbau von mobilen und leitungsgebunden Breitbandnetzen beschleunigen können. Zu diesem Zweck haben wir zehn Fallbeispiele näher analysiert und Expertengespräche mit...

Mobile phone coverage has expanded considerably throughout the developing world, particularly within sub-Saharan Africa. Existing evidence suggests that increased access to information technology has improved agricultural market efficiency for consumer markets and certain commodities, but there...
