The paper evaluates the impact of technology together with resource endowme
nts, factor prices and economies of scale on international competitiveness
in OECD countries. Knowledge capital stocks are obtained by cumulating R&D
expenditure. Results show that competitiveness is determined not only by th
e R&D activity of the representative firm, but also by total R&D in the dom
estic industry as well as economywide stocks of knowledge, indicating the p
resence of local externalities. Competitiveness is also affected by factor
prices and resource endowments as well as scale economies and learning by d
oing. Further results point to the importance of economies of scale in R&D
internal to the firm, of the degree of openness for the capacity to utilize
global spillovers and of investment for introduction of embodied technical
progress. Finally, the R&D impact is higher in high- and medium- than in l
ow-tech industries. (C) 1999 Elsevier Science B.V. All rights reserved.
