Fixed-line incumbents often 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 networks...

In this paper we study the impact of different forms of access obligations on firms’ incentives to migrate from the legacy copper network to next generation broadband infrastructures. We analyze geographically differential access prices of copper (that depend on whether or not an alternative...
