In accordance with the development of broadband services, interests are focused on the deployment of optical fiber and various reports and researches are published, including "Next Generation Connectivity" by the Berkman Center, Harvard University, and "Indicators of Broadband Coverage" by OECD....

Technological progress allows Internet Service Providers (ISPs) to carry out network manage-ment practices in a discriminatory fashion without being detected by their customers. This creates an opportunity that providers will exploit this information asymmetry in an opportunistic way by blocking...

In the current telecommunications domain, a clear trend towards vertical disintegration is observed, whereas multiple actors take up different roles in the value chain instead of one monopoly operator that is responsible for the full service delivery. Although this trend is observed in different...

Traditionally, neoclassical economics has been the guiding framework in the development of legislative and regulatory rules in the telecommunication markets. The regulatory perspective has long assumed a static environment. However, telecommunication markets have evolved into extremely dynamic,...

We study the implementation of reasonably efficient operator margin squeeze tests by National Regulatory Authorities in European telecommunications markets. We provide a theoretical framework in which we show how regulatory authorities deal with the asymmetries between the entrants and the...

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...

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...

The availability of undersea cables around Africa has been transformed by a recent surge of investment, ending the monopoly in West Africa and an absence in East Africa. Private investors alone and with governments have funded the laying of cables. Consequently, previous calls for regulated...
