This study investigates the long-term effects of various types of R&D on multifactor productivity growth, which is the spillover effect of R&D. Econometric estimates are conducted on a panel of 16 OECD countries, over the period 1980-98. All results are averages over countries and time, and little can be said about country specificities.

Major results are as follows: an increase of 1% in business R&D generates 0.13% in productivity growth. The effect is larger in countries which are intensive in business R&D, and in countries where the share of defence-related government funding is lower; a 1% increase in foreign R&D generates 0.44% in productivity growth, and the effect is larger in countries intensive in business R&D; 1% more in public R&D generates 0.17% in productivity growth. The effect is larger in countries where the share of universities (as opposed to government labs) is higher, in countries where the share of defence is lower, and in countries which are intensive in business ...

Cette étude analyse les effets de long terme de différents types de R-D sur la croissance de la productivité totale des facteurs, qui est l’effet « spillover » de la R-D. Les estimations économétriques sont conduites sur un panel de 16 pays de l’OCDE sur la période 1980-98. Les résultats obtenus sont des moyennes sur l’ensemble des pays et des années, ils ne reflètent pas les spécificités nationales. Les principaux résultats sont les suivants. Un supplément de 1 % de R-D des entreprises engendre une croissance de 0.13 % de la productivité. Cet effet est plus fort dans les pays où les entreprises réalisent plus de R-D, et dans les pays où la part des financements gouvernementaux liés à la défense est plus faible. Un supplément de 1 % de R-D étrangère engendre une croissance de 0.44 % de la productivité, et cet effet est plus fort dans les pays où les entreprises réalisent plus de R-D. Un supplément de 1% de R-D publique engendre une croissance de 0.17 % de la productivité. Cet effet ...
