Abstract

L'exposé présente un certain nombre d'éléments expliquant pourquoi les activités se développant sur le Net ne peuvent pas être bien appréhendées dans un contexte de concurrence parfaite, et discute la nature des barrières à l'entrée. Nous verrons que l'essentiel des changements qu'Internet impose du point de vue économique peut être relié à la nature particulière des biens d'information en tant qu'objet d'échange, ainsi qu'à l'importance des effets de réseau. D'un point de vue concret, les problèmes essentiels dont nous parlerons sont liés à la mise sur le marché des biens d'information, et au fonctionnement des marchés vu au travers des agents qui les construisent, une catégorie regroupée sous le terme d'intermédiaires.
