The study uses aggregate and manufacturing sector data for a group of ten OECD countries for the period 1971 to 1995 to estimate a system of two equations implied by a model of R&D-induced growth in steady state. These equations relate R&D intensity to productivity growth and the latter to...

We develop a model where temporary non-technology shocks can lead to permanent changes in the rate of growth of total factor productivity (TFP). The key ingredient of the model is a matching processes between basic researchers, product developers, and the stock of knowledge of the economy. In...
