Countries that innovate by conducting R&D activities always have high economic growth and many researchers emphasized this prominent role of the R&D on economic growth in numerous studies. This study contributes in two ways to this stream of research. Providing new estimates of the effect of R&D expenditures on economic growth is the first contribution to literature. On the other hand, there are different types of R&D expenditures and each of them has different magnitude on the economic growth. Therefore, this study provides evidences about the magnitudes of R&D expenditures. The effect of different types of R&D expenditures on economic growth for the selected OECD countries is examined in this study by utilizing from GMM framework using the data belonging the period of 2003-2014. Income and different R&D expenditure data used to analyze that obtained from OECD Stat. As a conclusion, it is found that all of the R&D expenditures have positive and significant effect on economic growth in selected OECD countries but magnitudes are various. Therefore, policy makers should design the R&D stimulation policies depending on the characteristics of the countries. Accordingly, countries must allocate more resources to different types R&D expenditure for achieving sustainable rate of growth.
