Abstract:
This paper analyzes differences in R&D spending and in the impact of R&D on productivity betweenGerman and UK firms. We confirm that German firms spend significantly larger amounts on R&D thantheir UK counterparts, even after controlling for firm size and industry effects. Using a dynamicproduction function approach, we find that the R&D output elasticity is approximately the same in bothcountries, implying a much larger rate of return on R&D in the UK than in Germany. We discuss severalexplanations for this result.
