Using data for 14 OECD countries and 13 sectors for the period 1985-2004, this paper analyzes the significance of the linkage between channels of international knowledge spillovers and total factor productivity. We distinguish between domestic and international intra- and inter-sectoral...

We study four issues in R&D–productivity dynamics: does R&D Granger cause productivity, is there a lag between R&D and its productivity effects, does the potency of R&D vary in timing and magnitude, and what is the role of R&D spillovers and aggregate shocks. The results suggest that R&D...
