Abstract

Cet article s'intéresse aux concentrations horizontales dans des marchés reliés verticalement. Dans un modèle de concurrence à la Cournot à deux niveaux, où les transactions se font par l'intermédiaire d'un marché, on montre que des fusions horizontales engendrant des effets de taille sont, toutes choses égales par ailleurs, plus profitables en aval qu'en amont. De plus, la concentration dans un secteur réduit les incitations à la fusion dans l'autre secteur. L'endogénéisation des décisions de fusion conserve ces résultats.
