Croissance optimale fondée sur la R&D : Combien pour la recherche et combien pour le développement ?


  • Fabien Tripier


This paper studies the optimal growth when research and development are explicitly distinguished. To this end, we perform the quantitative welfare analysis of an original model based on (i) a matching process between research and development and (ii) a competitive search process that determines the sharing rule of profits between firms. The model is calibrated to reproduce the stylized facts of the post-war United-States growth. Results indicate that both research and development activities have to be supported to reach the optimal growth, but the support is stronger for the first: private research investments have to be multiplied by eight against by two for private development investments.
