This paper evaluates the main measures that have been used to regulate the interconnection prices in the telecommunication sector. We show that many of the regulations that are applying the vast majority of countries have very little theoretical support, and we identify the restrictions that...

Condiciones propicias de interconexion en redes de telecomunicaciones son fundamentales para que se alcance un nivel alto de competencia. Se considera que estudiar bajo que condiciones se generan mejores tarifas de interconexion puede ayudar a disenar politicas que permitan alcanzar una mejora...

We analyze how network regulation affects investment into network infrastructure and complementary services. While regulation negatively affects investment incentives in the regulated network market, the effects of network regulation on investment in complementary services can be either negative...

The objective of this paper is to find the key factors that affect a firm's optimal transfer pricing policy. It examines two minimalist vertical models — one consisting of a vertically integrated firm monopolizing an intermediate input for its own and rival's downstream division, and the other...

A model of interaction between hardware vendors, Intel and AMD, and developers ofWindows and Linux operating systems is suggested. Intel and AMD both maximize profits forming atraditional oligopoly, while Microsoft and the community of Linux developers form a mixedduopoly, in which only the...

This paper considers the collusive stability of downstream competition in a vertical market with network externalities and cost asymmetry. A dynamic collusion game is constructed, and backward induction is employed to solve the subgame perfect Nash equilibrium. We show that larger network...

Do telecoms really contribute to the economic development of developing countries ? After funding a new mobile phone operator in Haiti, the Agence Française de Développement and Proparco have been willing to assess the impact of the arrival of this new operator on the Haitian economy. This...

The debate on the regulation of Next General Access started in Europe several years ago. It addresses the question of whether or not fibre access networks should be subject to the same regulation as the copper local loop. This debate is often examined as competition vs. investment. The present...

We reconsider the question of the optimal level of termination fees between communication networks in the context of heterogeneous usage and elastic participation. The interaction between these two features yields new insights; in our model: i) The profit maximizing reciprocal termination fee is...

The question of whether bundles of telecommunication services are relevant product markets is addressed. As a first step, demand for bundles of services, as well as the associated services, is modeled as a discrete choice problem with a potentially large number of products. A unique invoice...
