Abstract

[ger] Die wirtschaftliche Bedeutung der Kontrolle der Unternehmenszusammenschlüsse: ein einfaches Modell, . von Didier Maillard.. . Im Rahmen eines Cournotschen oligopolistischen Wettbewerbs wird eine Bewertung der Unternehmenskonzentrationen versucht. Die Unternehmenszusammenschlüsse haben einen Verlust des kollektiven Wohlstandes zur Folge, wenn sie nicht mit einer Rationalisierung und mit genügend Kosteneinsparungen einhergehen. Die Anwesenheit ausländischer Konsumenten trägt dazu bei, daß die um das nationale Wohlergehen besorgten Behörden die Zusammenschlüsse eher akzeptieren. [fre] Les enjeux économiques du contrôle des concentrations : un modèle simple, . par Didier Maillard.. . Une évaluation des concentrations d'entreprises est tentée dans le cadre d'une concurrence oligopolistique à la Cournot. Les fusions d'entreprises se traduisent par une perte de bien-être collectif lorsqu'elles ne s'accompagnent pas d'une rationalisation et d'économies de coût suffisantes. La présence de consommateurs étrangers tend à rendre les concentrations plus facilement acceptables par les autorités soucieuses du bien-être national. [spa] Bazas económicas del control de concentraciones: un modelo simple, . por Didier Maillard.. . En el presente artículo se intentan evaluar las concentraciones de empresa dentro del marco de una competencia oligopolística a la Couraot. Las fusiones de empresas provocan una pérdida de bienestar colectivo, cuando no van acompañadas de una rationalización y reducciones de coste suficientes. La presencia de consumidores extranjeros hace que las autoridades, preocupadas por el bienestar nacional, acepten las concentraciones con mayor facilidad. [eng] The Economic Issues involved in Controlling Concentrations: A Basic Model, . by Didier Maillard.. . An attempt is made to assess corporate concentrations within a framework of oligopolistic competitiveness at La Cournot. Corporate mergers result in a decrease in welfare all around if not enough rationalization and cost savings are put into them. When there are foreign consumers, the authorities, concerned over domestic welfare, tend to accept concentrations more easily.
