In Europe Mobile Termination Rates (MTR) are being subject to reduction to reflect actual costs, marginal or incremental, of calls termination in mobiles nets. This is considered as an intermediate step to adopt the “bill-and-keep” system. Other countries around the globe, such as New...

We revisit Greif's (1993) analysis of trade between the 11th-century Maghribi traders and present two different models which bring into play, in an essential way, historical features of the Maghribi's organization which had no role in Greif's own analysis. Our reformulation of the Maghribi's...

This paper presents results from a calibrated welfare model of the UK mobile telephony market which includes many mobile networks; calls to and from the fixed network; networkbased price discrimination; and call externalities. The analysis focuses on the short-run effects of adopting lower...

With particular reference to the structure of the U.K. industry, price competition in a deregulated wholesale market for electricity is modeled as a sealed-bid multiple-unit auction with a random number of units. It is argued that, under the existing regulatory rules, one must expect volatile...

The conventional wisdom that mobile operators are able to act as monopolists in pricing call termination on their networks has recently been challenged by Hutchison 3G’s entry into European mobile markets. The European Commission’s electronic communications regime allows national regulatory...

This paper surveys the recent literature on competition between mobile network operators in the presence of call externalities and network effects. It shows that the regulation of mobile termination rates based on “long-run incremental costs” increases networks’ strategic incentives to...

This paper surveys the recent literature on competition between mobile networks in the presence of call externalities and network effects. It argues that the regulation of mobile termination rates based on fully allocated costs, or “long-run incremental cost plus”, exacerbates the network...
