We introduce a model of asymmetric competition where two network operators with different investment costs may build an internet access infrastructure and where a virtual operator provides services through third-party access. We show that the virtual operator requests access from the low cost...

We analyze competition between vertically integrated infrastructure operators that provide access in different geographical areas. A regulator may impose a uniform access price, set local access rates, or deregulate access locally. We analyze the impact of these alternative regulatory regimes on...

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...

In this paper, we analyze the incentives of an incumbent and an entrant to migrate from an “old” technology to a “new” technology, and discuss how the terms of wholesale access affect this migration. We show that the coverage of the new technology varies non-monotonically with the access...

We analyse competition between vertically-integrated operators who build infrastructure and provide access in different geographical areas. Under full commitment, the regulator sets socially-optimal access rates that depend on the local degree of infrastructure competition. If he can only commit...
