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...

This article proposes a duopoly model based on a model initially introduced by Shubik and Levitan to analyze the competition based on mobility and data volume between fixed and mobile broadband access. By the description of asymmetrical characteristics of fixed and mobile broadband offers and...

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...
