National and International Spillovers from R&D: Comparing a Neoclassical and an Endogenous Growth Approach
Abstract: Two models where productivity growth is caused by
spillovers from R&D are analysed using a sample of nine manufacturing
industries in six large OECD-countries between 1979 and 1991. The first
model is based on traditional productivity analysis where growth in R&D
stocks causes productivity growth. The second model is based on the
endogenous growth literature where the level of R&D expenditures is assumed
to increase productivity growth. The empirical results indicate stronger
support for the latter model. The pattern of spillovers is also
investigated. The results suggest that spillovers from R&D exist within
industries, both nationally and internationally. There is, however, little
evidence of spillovers between industries. The empirical evidence further
suggests that intra-industry spillovers are confined to industries that are
relatively R&D-intensive. Finally, direct foreign investment seem to
facilitate the diffusion of R&D results, but we do not find any effect on
growth from R&D embodied in intermediate products.
