    Abstract

    [fre] Innovation, propriété intellectuelle, croissance. . Cet article explore les conséquences de l'innovation de produit avec protection par brevets dans un cadre de croissance endogène. Des biens nouveaux monopolistiques coexistent avec des biens anciens concurrentiels. L'équilibre décentra­lisé n'est pas optimal car il n'intègre pas les effets externes de l'innovation et il entraîne des distorsions dans l'allocation des ressources du fait des distorsions de prix. Le taux de croissance du produit à l'équilibre peut être moins élevé ou plus élevé que le taux de croissance optimal. Les pouvoirs publics ont deux instruments d'intervention : la durée du brevet ; les taxes ou subventions aux entreprises. Un travail statistique sur données américaines permet de mettre en évidence le caractère endogène de l'innovation. [eng] Innovation, intellectual property, growth. . The paper explores the consequences of product innovation with patents protection, in an endogenous growth framework. New goods are temporarily monopoli stic and old ones are competitive.. Competitive equilibrium is not optimal because of external effets of innovation, and price distorsions induces distorsions in the allocation of ressources.. The competitive growth rate may be lower or higher than the optimal one. Public authorities have two means of action : length of patents, and taxes or subsidies to firms. A statistical test on US patents data shows that technological innovation is endogenous.
