Engouement collectif et concurrence

[eng] Collective passions and competition. . The development of collective passions for some goods or services may drastically affect the structure of the corresponding markets, and may even lead to the destruction of competition. Specifically, it is shown by using a simple model of spatial competition that the emergence of a dominant product on a market may be explained by the presence of social externalities in consumption. [fre] Engouement collectif et concurrence. . L'engouement collectif pour certains biens ou services est susceptible d'affecter de manière profonde les modalités de la concurrence sur les marchés correspondants. Un tel comportement peut aller jusqu'à la destruction de cette concur­rence en provoquant la disparition des produits concurrents. À l'aide d'un modèle simple de concurrence spatiale, on montre en effet comment la présence d'externalités sociales de consommation est susceptible de provoquer l'émergence d'un produit dominant sur le marché.
