R&D et innovations technologiques au sein d'un marché monopolistique d'une ressource non renouvelable

  • Poudou, J.-C.

Ce document présente une analyse théorique du comportement de R&D et d’innovation technologique d’une firme minière en situation de monopole. Deux types d’innovations de processus d’extraction y sont proposés. D’une part la R&D débouchera sur des innovations réductrices de coût, c’est-à-dire qui permettent de compresser le coût unitaire par mètre foré. D’autre part, l’innovation impliquera « l’accessibilité » à des réserves jusqu’alors probables ainsi qu’une hausse du coût unitaire d’exploitation. Ces deux comportements d’innovations produisent des effets opposés en matière d’épuisement de la ressource, mais leur impact sur le prix d’offre est voisin. Enfin le choix technologique du monopole minier (entre les deux modalités proposées) n’est pas neutre du point de vue du bien-être collectif, les innovations « d’accessibilité » pouvant être, sous certaines conditions, considérées comme meilleures.
