How effective are additional tax credits for R&D? A measurement using the social-experiment paradigm
Extra WBSO bevordert R&D bij starters
First, an additional tax credit was offered to new and innovating firms: the starters program. And second, the upper bound of the first tax-credit bracket was raised. We stress the importance of identifying a convincing control group in order to assess the causal impact of a policy change.
Each extra euro tax credit spent through the starters program yields about 50 to 80 eurocent extra R&D labour activity. The extension of the first tax-credit bracket yields about 10 to 20 eurocent extra R&D-labour for each additional euro tax credit. Identification of a convincing control group is difficult in the latter case however, casting uncertainty on the estimate.
