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

In this paper, we discuss the role of cable television networks and their ownership structure in promoting competition in the local access market. First, we show that the dual ownership of a local telephone network and a cable network, compared with separate ownership, may increase or decrease...

We analyze the product differentiation decision of a downstream entrant that purchases access to a bottleneck input from one of two vertically integrated incumbents, who will compete with him in the downstream market. First, an entrant chooses his product, then the entrant negotiates the access...

In this article we discuss the role of cable television networks and their ownership structure, in promoting competition in the local access market. An upgraded cable network can o¤er telecommunication services, and therefore can compete with the public switched telephone network. First, we...

In this article, we analyze the product differentiation decision of a downstream entrant that purchases access to a bottleneck input from one of two vertically integrated incumbents, who will compete with him in the downstream market. We develop a three-stage model, where first an entrant...

In this paper, we discuss the role of cable television networks and their ownership structure in promoting competition in the local access market. First, we show that the dual ownership of a local telephone network and a cable network, compared with separate ownership, may increase or decrease...

In this article, we discuss several aspects related to the entry of mobile virtual network operators. Some aspects, such as entry barriers and exclusionary practices, relate to the entry process itself. Other aspects, such as prices or the characteristics of the entrant’s product, relate to...

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,...

In this article, we analyze the incentives of vertically integrated oligopolists to concede access to their bottleneck inputs to an entrant in the downstream retail market. We develop a two-stage model, where in the first stage a downstream entrant negotiates an access price with three...
