[eng] Estimating the Productivity of Research and Development: an Exploration of GMM Methods Using Data on . French and United States Manufacturing Firms Jacques Mairesse and Bronwyn H. Hall . A comparative study of the contribution of R&D to firm-level productivity in French and United States manufacturing firms in the 1980s is presentend. The study suses two large panels of approximately 1000 manufacturing firms covering over half of all R&D spending in each country and focuses on the estimation and interpretation of the relationship between output growth and the growth of R&D investment in the prsence of simultaneity and firm heterogeneity. We use GMM methods to control for both sources of estimation bias, and we finf : overail, the contribution of R&D to sales productivity growth appears to have declined during the 1980s, the role of simultaneity bias is higher in the U.S. than in France, possibly reflecting the grater importance of liquidity constraints for R&D investment in that country. [fre] La productivité de la recherche et développement des entreprises industrielles aux États-Unis et en France . par Jacques Mairesse et Bronwyn H. Hall . II s'agit d'une étude comparée du degré de contribution de la R&D à la productivité au niveau de l'entreprise en ce qui concerne les sociétés manufacturières en France et aux États-Unis. L'étude utilise deux grands panels d'environ mille entreprises manufacturières auxquelles correspond plus de la moitié des dépenses R&D dans l'un et l'autre pays ; elle est centrée sur l'estimation et l'interprétation de la relation existant entre la croissance de la production et la croissance des investissements R&D en cas de simultanéité et d'hétérogénéité des entreprises. Nous utilisons les méthodes MGG pour contrôler l'une et l' autre sources de distorsion de l'estimation et nous constatons que : fait prédominant la contribution de la R&D à la croissance de la productivité des ventes semble être allé diminuant au cours des années quatre-vingts ; le rôle du biais de simultanéité est plus marqué aux État-Unis qu'en France, ce qui correspond peut-être à l'importance plus grande des contraintes de liquidités qui pèsent sur les investissements aux États-Unis.
