Abstract:
This paper analyzes di¤erences in R&D spending and in the impact of R&Don productivity between German and UK ¿rms. We con¿rm that German ¿rmsspend signi¿cantly larger amounts on R&D than their UK counterparts, even aftercontrolling for ¿rm size and industry e¤ects. Using a dynamic production functionapproach, we ¿nd that the R&D output elasticity is approximately the same inboth countries, implying a much larger rate of return on R&D in the UK than inGermany. We discuss several explanations for this result.
