N2 - This study uses newly available representative data from German business services firms and a continuous treatment approach based on the generalised propensity score to test for a causal effect of R&D activities (measured by the share of engineers and natural scientists in all employees) on the share of exports in total sales. We find evidence for a positive and statistically significant but small causal effect. This result is in line with the (non-causal) results reported in Innovation, Globalization and Firm Dynamics. Lessons for Enterprise Policy, New York, Routledge, 2014 and 137, based on regression models with and without control for unobserved time-invariant firm characteristics. The bottom line, then, is that R&D activity does matter for success of German business services firms on export markets - but not much.
