Technology spillovers between sectors and over time
Article Abstract:
A new method for measuring spillovers between manufacturing sectors was proposed based on patent citations. The main advantage of this method is that it can show how spillovers change over time and indicates the amount of spillovers. The results showed that the concentration of research and development (R&D) spillovers at larger spillover lags received declines gradually, but at short lags, spillovers were more concentrated than direct R&D. In addition, the time dimension of R&D spillovers should not be disregarded.

The diffusion of successive generations of a technology: a more general model
Article Abstract:
Numerous fields of technological development are characterized by distinct generations of technology where the new generation is more efficient than its predecessor. A study investigated two models of the diffusion of successive generations of technology to question their assumptions of constancy. It found empirical evidence of non-constancy in several areas of technology that have ramifications within the context of forecasting and planning.
