We present a calibrated model of the UK mobile telephony market with four mobile networks; calls to and from the fixed network; network-based price discrimination; and call externalities. Our results show that reducing mobile termination rates broadly in line with the recent European Commission...

U.S. network industry reforms led other countries in the past, but have recently run into difficulties in specific areas. In particular, the U.S. telecommunications sector was hit by a deep crisis and electricity reforms suffered under the California disaster. Part of the explanation for these...

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...

In this paper, we analyze the specific national broadband plans which have been developed by some European governments to foster the deployment of next generation access networks, namely in France, Italy, and Portugal. In particular, we discuss the strategies adopted to achieve wide fibre...

Regulators have long been aware of the social aspects of communication. In the past, regulated monopolists have provided Universal Service Obligations, typically funded via a system of cross-subsidies. In this paper, we first review the rationale for imposing Universal Service Obligations, based...

With the use of a laboratory experiment, we show the effects of co-investments on coverage, competition and price collusion in regulated network industries. On the one hand, co-investments turn out not to be a significant driver of new infrastructure investments beyond the level achieved by...

Our survey reviews the theoretical and empirical literature on all alternative policies to promote the deployment of new fiber-based communications infrastructure. Since such investment is expected to induce substantial positive externalities, dynamic efficiency becomes a particularly important...
