Abstract

[eng] Research Productivity and Returns to Scale in the French Pharmaceutical Sector by Nicolas lung and Frederic Rupprecht This paper studies research productivity in French pharmaceutical laboratories. We measure the elasticities of the number of new products launched and the sales made by these products to the size of the laboratory launching them. Our study suggests that the development of new pharmaceutical products is subject to constant or decreasing returns and economies of scope. These economies could make it profitable for firms working in separate therapeutic fields to merge. Constant or decreasing returns also prevail in the discovery of blockbusters, but without economies of scope. However, this type of pharmaceutical product might be expected to show increasing returns due to the greater impact of researcher specialisation and the fixed costs associated with purchasing sophisticated equipment. [fre] Productivité de la recherche et rendements d'échelle dans le secteur pharmaceutique français par Nicolas lung et Frédéric Rupprecht On étudie dans cet article la productivité de la recherche pour les laboratoires pharmaceutiques français. Pour cela, on mesure les élasticités du nombre de spécialités nouvelles introduites par un laboratoire ainsi que des ventes réalisées par cette spécialité à la taille du laboratoire qui les met sur le marché. Notre étude suggère que la recherche pharmaceutique de produits nouveaux est soumise à des rendements constants ou décroissants mais aussi à des économies de gamme. Celles-ci peuvent rendre attrayantes des fusions entre firmes positionnées sur des classes thérapeutiques disjointes. Quant à la découverte de blockbusters, elle semble aussi régie par des rendements constants ou décroissants mais sans économies de gamme. Pourtant, on aurait pu s'attendre pour ce type de médicaments à la mise en évidence de rendements croissants résultants de la plus grande importance de la spécialisation des chercheurs et des coûts fixes liés à l'achat de matériel sophistiqué.
