In telecommunications some operators have deployed their own networks whereas some others have not. The latter firms must purchase wholesale products from the former to be able to compete on the final market. We show that, even when network operators compete in prices and offer perfectly...

This paper studies the role of structural remedies in merger control in a Cournot setting where (endogenous) mergers are motivated by prospective efficiency gains and must be submitted to an Antitrust Authority (AA) which might require partial divestiture for approval. Both positive and negative...

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...

The 1994 Riegle Neal (RN) Act removed interstate banking restrictions in the US. The primary motivation was to permit geographic risk diversification (GRD). Using a factor model to measure banks' geographic risk, we show that RN expanded GRD possibilities in small states, but that few banks took...

We show that the prediction of a strategic connectivity breakdown under a receiving-party-pays (RPP) system and discrimination between on- and off-net prices does not hold up once more than two networks are considered. Indeed, equilibria with finite call and receiving prices exist for a large...

This paper studies the role of the failing firm defense (FFD) concept in merger control in a Cournot setting where: (i) endogenous mergers are motivated by prospective efficiency gains; and (ii) mergers must be submitted to an Antitrust Authority which might require partial divestiture for...

In many markets governments set minimum quality standards while some sellers choose to compete on the basis of quality by exceeding them. Such ‘high-quality’ strategies often win public acclaim, especially when ‘environmental friendliness’ is the dimension along which firms are...

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,...

We introduce a flexible model of telecommunications network competition with non-uniform calling patterns, which account for the fact that customers tend to make most calls to a small subset of people. Equilibrium call prices are distorted away from marginal cost, and competitive intensity is...
