IZA DP No. 9937: The Productivity Impact of R&D Investment: A Comparison between the EU and the US
published as 'R&D and Productivity in the US and the EU: Sectoral Specificities and Differences in the Crisis', Technological Forecasting and Social Change, 2019, 138, 279-291.
Using data on the US and EU top R&D spenders from 2004 until 2012, this paper investigates the sources of the US/EU productivity gap. We find robust evidence that US firms have a higher capacity to translate R&D into productivity gains (especially in the high-tech industries), and this contributes to explaining the higher productivity of US firms. Conversely, EU firms are more likely to achieve productivity gains through capital-embodied technological change at least in medium and low-tech sectors. Our results also show that the US/EU productivity gap has worsened during the crisis period, as the EU companies have been more affected by the economic crisis in their capacity to translate R&D investments into productivity. Based on these findings, we make a case for a learning-based and selective R&D funding, which – instead of purely aiming at stimulating higher R&D expenditures – works on improving the firms' capabilities to transform R&D into productivity gains.
