We propose a two-sided model with two competing Internet platforms, and a continuum of Content Providers (CPs). We study the effect of a net neutrality regulation on capacity investments in the market for Internet access, and on innovation in the market for content. Under the alternative...

We study the regulation of a utility firm which is active in a competitive unregulated sector as well. If the firm jointly operates its activities in the two markets, it enjoys economies of scope, whose size is the firm’s private information and is unknown to the regulator and the rival firms....

This paper analyses the effects of universal service obligations, such as uniform pricing, coverage constraints and price caps, on markets newly opened to competition, e.g. broadband services. We show that the requirement of uniform pricing has strong repercussions on coverage decisions. Imposed...

This paper analyses the pattern of state aids to the manufacturing sector in ten EC countries for the period 1981--90. It focuses on determinants suggested by the political economy of state aids. We estimate a regression model where the intensity of state aids is accounted for by the weakness of...

We analyze the impact of mandatory access on the infrastructure investments of two competing communications networks, and show that for low (high) access charges firms wait (preempt each other). Contrary to previous results, under preemption a higher access charge can delay first investment....

Regulators have recently shown an increased sensitivity to the issue of price squeezes, especially telecom regulators in European countries. This Paper analyses the relevance and the scope of price squeeze tests as proposed by practitioners and economists, taking the existing regulatory...

We analyze competition between vertically integrated infrastructure operators that provide access in different geographical areas. A regulator may impose a uniform access price, set local access rates, or deregulate access locally. We analyze the impact of these alternative regulatory regimes on...

This paper questions whether competition can replace sector-specific regulation of mobile telecommunications. We show that the monopolistic outcome prevails independently of market concentration when access prices are determined in bilateral negotiations. A light-handed regulatory policy can...

The purpose of this article is to investigate the prospects for entry into an existing network in the telecommunication industry, and how public policy may promote a more competitive outcome. We apply a model that captures the fact that the incumbent has an installed base of loyal consumers,...
