The present project is oriented to evaluate the performance of technological trade and research and development (R&D) expenditure, as a measure of productivity in explaining economic growth. Using data for OECD countries under a simple neoclassical growth model framework, the role of technology trade and investment in R&D is verified as an approximate measurement of productivity. In this case two thirds of total economic growth can be explained jointly by the introduction of these two variables in to the model specification together with human and capital accumulation.
