This article addresses the impact of regulatory policy on levels of infrastructure deployment and derived welfare in the telecommunications sector. The model considers two potentially coexisting and partially competing techniques (the old ADSL - Asymmetric Digital Subscriber Line - technique) -...

Network operators of competing infrastructures in European electronic communications markets face asymmetric regulation: incumbent telecommunications firms are required to open their networks for retail broadband competition, while cable companies have no such obligation. Furthermore, for...

We study the impact of the access charges of copper and fiber unbundling on an incumbent's incentives to invest in fiber access networks. Once the fiber deployment is in place, the incumbent and the entrant compete for consumers in both copper and fiber markets. We show that when the regulator...

In this paper we study how the coexistence of access regulations for legacy (copper)and fiber networks shapes the incentives to invest in network infrastructure. To this end, we develop a theoretical model explaining investment incentives by incumbent telecom operators and heterogeneous entrants...

In this paper, we study the adjustments made by National Regulatory Authorities to simple margin squeeze tests, in order to model a reasonably efficient operator. More precisely, by inspecting the possible differences between an entrant and an incumbent that would cause a market disadvantage for...

In this paper, we study the adjustments that National Regulatory Authorities make to simple margin squeeze tests, when using them ex-ante. More precisely, by inspecting the possible differences between an entrant and the incumbent that would cause a market disadvantage for the former, we provide...
