This paper investigates the impacts of the current roaming rules on domestic competition and welfare. We consider a model for two countries in which each country has two operators that compete in the retail market for access services and also in the wholesale market for roaming. We first derive...

We analyse network competition in a market with international calls. National regulatory agencies (NRAs) have incentives to set regulated termination rates above marginal cost to extract rent from international call termination. International network ownership and deregulation are alternatives...

We develop a model of competition between interconnected networks, with separate local and long-distance markets, allowing for various degrees of symmetry between carriers. Assuming two part pricing, we show that effective competition can be achieved with simple regulations involving mandatory...

The Scottish National Party (SNP) government in Scotland has published an outline of how it wishes economic and competition regulation to operate in the event that it is successful in persuading the residents of Scotland to vote in September 2014 for independence in March 2016. It envisages a...

The best proposals for network neutrality rules are simple. They ban abusive behavior like tollboothing and outright blocking and degradation. And they leave open legitimate network services that the Bells and Cable operators want to provide, such as offering cable television services and voice...

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 analyse competition between perfectly substitutable networks. Monopolization can be sustained in equilibrium by asymmetric access prices whereby entry is deterred by a set of margin squeezes. A regulatory package consisting of (i) mandatory interconnection; (ii) reciprocal access prices;...
