    Abstract

    On étudie les forces qui régissent l'agrégation des sites Web marchands (B-to-C) en concurrence sur un marché électronique différencié, où le coût de recherche pour les consommateurs est indépendant du coût d'adaptation/transport supporté lorsque le bien trouvé ne correspond pas à leur préférence. On s'intéresse à la possibilité pour les sites Internet de se coaliser, ce qui se traduit par une réduction du coût de recherche pour trouver d'autres sites à l'intérieur de la coalition. On effectue la statique comparative des structures de coalitions (en fonction du degré de différenciation de ses partenaires) lorsque les sites se font une concurrence en prix. On montre qu'un site préfère se coaliser avec un partenaire fortement différencié et fixe dans ce cas un prix unique plus bas.
