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...
