Résumé / Abstract Nous étudions le processus de séparation entre une firme à l'aval et des firmes à l'amont qui lui fournissent des inputs complémentaires. À cause d'un effet stratégique négatif, le profit marginal de la firme à l'aval de garder une firme à l'amont comme filiale est moins élevé que la valeur de cette dernière au marché des bourses. La séparation est immédiate si le nombre de filiales à l'amont est inférieur à un certain niveau critique. La séparation est graduelle dans le cas inverse et demande une stratégie mixte éventuelle. In a model where a monopolistic downstream firm (assembler) negotiates simultaneously with each of its intermediate-input suppliers the prices of the complementary components which enter its product, we analyze the process by which the assembler separates from its suppliers as a Markov Perfect equilibrium.
