The European Commission believes that for the regulation of next generation fixed telecommunications networks the continuity approach is preferable to the equality of access approach and the no-regulation approach. According to the European Commission, (i) functional separation eliminates...

We analyze if two-part access tariffs solve the dynamic consistency problem of the regulation of next generation networks. We model the industry as a duopoly, where a vertically integrated incumbent and a downstream entrant, that requires access to the incumbent's network, compete on Hotelling's...

We analyze the impact of network neutrality regulation on: (i) competition between CPs, and on (ii) ISPs. incentives to invest. We consider both competition between ISPs and between CPs and show that, if ISPs can o¤er network services of different quality to CPs, they prefer to sell the highest...

We analyze if two-part access tariffs solve the dynamic consistency problem of the regulation of Next Generation Networks. We model the industry as a duopoly, where a vertically integrated incumbent and a downstream entrant, that requires access to the incumbent's network, compete on Hotelling's...

We analyze the incentives of a telecommunications incumbent to invest and give access to a downstream entrant to a next generation network, NGN. We model the industry as a duopoly, where a vertically integrated incumbent and a downstream entrant, that requires access to the incumbent's network,...

We analyze …firms incentives to bundle and tie in the telecommunications industry. As a fi…rst step, we develop a discrete-choice demand model where fi…rms sell products that may combine several services in bundles, and consumers choose assortments of different types of products available...

The question of whether bundles of telecommunication services are relevant product markets is addressed. As a first step, demand for bundles of services, as well as the associated services, is modeled as a discrete choice problem with a potentially large number of products. A unique invoice...

In this article, one makes two points about the impact of bundles on competition and regulatory policy. First, one argues that the growing importance of bundles requires an adjustment in the current framework of relevant product markets for individual services, and that the traditional tools of...
