In this paper we study concentration in the European Internet upstream access market. Measurement of market concentration depends on correctly defining the market, but this is not always possible as Antitrust authorities often lack reliable pricing and traffic data. We present an alternative...

Is the quality of interconnection between Internet operators affected by their asymmetry? While recent game theoretic literature provides contrasting answers to this question, there is a lack of empirical research. We introduce a novel dataset based on Internet routing policies, and study the...

Recent industry studies found the Internet backbone industry competitive. In our paper we explore a novel route to monitor for market power using prices and quality data from Band-X. First we test the hypothesis that Europe is a connectivity market on its own, unchallenged by the US and then, by...

In the Internet information packets are routed through many vertically related hops. However these network hierarchies are not fixed. Two providers can be simultaneously vertically related in a routing process as supplier and retailer, while horizontally competing in another. We study pricing...

Peering decisions between Internet Service Providers contain substantial non-measurable aspects requiring trust and informal cooperation among peering partners. We study whether spatial agglomeration is observed between Internet peers. Our empirical analysis of the bilateral peering decisions at...

In this paper we study concentration in the European Internet upstream access market. Measurement of market concentration depends on correctly defining the market, but this is not always possible as Antitrust authorities often lack reliable pricing and traffic data. We present an alternative...

Does asymmetry between Internet Providers affect the “fairness” of their interconnection contracts? While recent game theoretic literature provides contrasting answers to this question, there is a lack of empirical research. We introduce a novel dataset on micro-interconnection policies and...
