Unbundling of the local loop (ULL) has seen quite different "success stories" in the various countries across Europe. Although the obligation for the provision of ULL was implemented in the regulatory framework early and mostly parallel to other means of liberalisation, national implementation...

This paper addresses the question of what options are available to regulate the sector in the near future. In order to answer this question, the paper focuses on the problem of investment and innovation in an ex ante regulated sector. Relying on existing literature, we argue that ex ante...

Is the United States in full retreat from internationally recognized regulatory best practice? Or is it instead headed toward some different destination – "dancing to the beat of a different drummer"? Where is this likely to lead?

This article discusses changes in the U.S. telecommunications market over the last decade and argues that increasing competitive substitution from wireless and internetbased communications has undermined the rationale for conventional monopoly regulation of incumbent local telephone carriers....

P2P networks have mainly been used for downloading cultural goods. This sociological research focuses on the practices and norms of users and designers. Drawing on a qualitative survey, it explores the many ways sharing takes place. It looks at P2P networks as file sharing communities and probes...

The literature on the effects of market concentration in platform industries or two-sided markets often compares the competitive outcome against a benchmark. This benchmark is either the “joint management” solution in which one decision maker runs all platforms or a “pure” monopoly with...

We investigate the social desirability of free entry in the co-opetition model in which firms compete in a homogeneous product market while sharing common property resources that affect market size or consumers' willingness to pay for products. We show that free entry leads to socially excessive...

This paper investigates regulation by auctions of private supply of congestible infrastructures in two networks settings: 1) two serial facilities, where the consumer has to use both in order to consume; and 2) two parallel facilities that are imperfect substitutes. There are four market...

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...

We propose both a monopoly and a duopoly model of a two-sided market. Both settings are fully comparable, as we impose a homogeneous good produced at zero costs without capacity constraints, as well as identical parameterization of market sizes. We determine the duopoly equilibrium and the...
