We analyze how termination charges affect retail prices when taking into account that receivers derive some utility from a call and when firms may charge consumers for receiving calls. A novel feature of our paper is that we consider passive self-fulfilling expectations and do not allow for...

Alternative telecom operators have continuously invested in their own infrastructure in recent years. After more than a decade since liberalisation, competitive conditions have substantially changed, especially in urban areas. European regulatory authorities have acknowledged this development by...

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...

This paper develops a simple reduced form model of two-way network competition with linear retail pricing. Using the techniques of supermodular games, it is demonstrated that the most important results from the existing literature do not depend on routinely invoked assumptions, such as specific...

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...

Typically, incumbent providers enjoy a demand-side advantage over any entrant. However, market entrants may enjoy a supply-side advantage in costs over the incumbent, since they are more efficient or operate on innovative technologies, such as the voice of internet protocol (VoIP) telephony....

In this paper, we examine welfare implications of switching from a neutrality regime to a network management regime. While in the former a network provider or an integrated ISP should transmit data with a-bit-is-a-bit principle, in the latter it is allowed to differentiate its connection quality...

In many telecommunications markets incumbent providers enjoy a demand-side advantage over any entrant. However, market entrants may enjoy a supply-side advantage over the incumbent, since they are more efficient or operate on innovative technologies. Considering both a supply-side and a...

Network shares and retail prices are not symmetric in the telecommunications market with multiple bottlenecks which give rise to new questions of access fee regulation. In this paper we consider a model with two types of asymmetry arising from different entry timing, i.e. a larger reputation for...
