Abstract: This paper investigates the significance of Research and Development (R&D) spillovers through intra- and international trade in intermediate goods for productivity growth in a panel of OECD industries during 1973-1994. In the model, four different sources of R&D are identified: R&D conducted in the particular industry itself, R&D conducted in the same industries in other countries, R&D conducted in other domestic industries, and R&D conducted in other foreign industries. I find that among R&D sources the most important contributions to productivity growth come from the domestic R&D efforts. Here, own R&D is important for both domestic innovation and for the productivity catch-up process. Evidence that international R&D spillovers also have significant effects on productivity growth is found to be less robust. My analysis also shows that human capital affects productivity directly as a factor of production.
