Abstract

L'objectif de cet article est d'étudier l'impact du tarif forfaitaire de responsabilité (TFR) sur la part de la marge du grossiste attribuée au pharmacien et sur l'effort de substitution entre marque et générique. Nous considérons une situation dans laquelle le génériqueur vend directement son générique au pharmacien et le laboratoire de marque vend son princeps par l'intermédiaire d'un grossiste. Nous supposons que les produits sont verticalement différenciés et nous résolvons un jeu en deux étapes. A la première étape, le génériqueur détermine la part de la marge du grossiste qu'il consent au pharmacien afin de l'inciter à substituer et, si un tarif forfaitaire de responsabilité est introduit, les firmes se concurrencent en prix. A la seconde étape, le pharmacien choisit son effort de substitution. Nous montrons que l'introduction du TFR augmente la part de la marge du grossiste allouée au pharmacien par le génériqueur, mais diminue l'effort de substitution du pharmacien.
