    Abstract

    [fre] Ouverture à la concurrence dans les réseaux : l'approche stratégique de l'économie des réseaux . par Anne Perrot . L'économie des réseaux, développée depuis le milieu des années quatre vingt, examine les conséquences des comportements stratégiques à l'œuvre sur les marchés caractérisés soit par la présence d'externalités de réseaux (externalités d'offre ou de demande) soit par la nature de biens-systèmes des produits offerts. Joints aux avancées de la théorie de la réglementation, qui envisage les implications des situations d'information asymétrique entre le régulateur et les firmes régulées, ces travaux donnent des éclairages féconds sur l'organisation qui devrait prévaloir dans les activités autrefois confiées aux monopoles publics. Cet article examine les implications de ces avancées théoriques pour le fonctionnement des secteurs ouverts à la concurrence (transports, télécommunications, énergie, ..). [spa] Apertura à la competencia en el ârea de sistemas: enfoque estratégico de la economia de sistemas . por Anne Perrot . La economia de sistemas, desarrollada desde mediados de los anos ochenta, examina las consecuencias de los comportamientos estratégicos implementados en los mercados caracterizados ya sea por la presencia de externalidades de sistemas ( externalidades de oferta o de demanda ) ya sea por la naturaleza de los bienes-sistemas de los productos ofrecidos. En consonancia con los progresos de la teorîa de la reglamentaciôn, que estudia las implicaciones de las situaciones de information asimétrica entre el regulador y las firmas reguladas, estos trabajos aportan esclarecimientos fecundos sobre la organization que deberîa prevalecer en las actividades anteriormente confïadas a los monopolios pûblicos. Este articulo examina las implicaciones de estos progresos teoricos en el funcionamiento de los sectores abiertos a la competencia ( transportes, telecomunicaciones, energia,..) . [ger] Offnung der Netze fur den Wettbewerb: der strategische Ansatz der Netzwirtschaft . von Anne Perrot . Die Netzwirtschaft, die seit Mitte der achtziger Jahre entwickelt wird, priift die Konsequenzen der strategischen Verhaltensweisen auf den Markten, die sich entweder durch das Vorhandensein von Netzexternalitaten (Angebots- oder Nachfrageexternalitaten) oder durch die giiter- und systembezogene Beschaffenheit der angebotenen Produkte auszeichnen. Gemeinsam mit den Fortschritten der Reglementierungstheorie, die die Auswirkungen der Situationen mit asymmetrischer Information zwischen der Regulierungsbehôrde und den regulierten Unternehmen untersucht, geben dièse Arbeiten intéressante Aufschliisse iiber die Organisation, die bei den Tatigkeiten vorherrschen sollte, die friiher den ôffentlichen Monopolen ubertragen waren. In diesem Artikel werden die Folgen dieser theoretischen Fortschritte fur die Funktions weise der Sektoren untersucht, die dem Wettbewerb geôffnet werden (Transport, Telekommunikation, Energie usw.). [eng] Opening Up Networks to Competition: The Strategic Network Economy Approach . by Anne Perrot . The network economy, developed since the mid-1980s, examines the consequences of strategic behaviour at work in the markets featuring either the presence of network externalities (supply or demand externalities) or the goods-systems nature of the products provided. When combined with advances in regulation theory, which envisages the implications of asymmetric information situations between regulator and regulated firms, this study throws a great deal of light on the organization that should predominate in the activities previously entrusted to public monopolies. The article studies the implications of this theoretical progress for the operation of the sectors open to competition (transport, telecommunications, energy, etc.).
