The Directorate General for Research and Innovation of the European Commission commissioned Deloitte and RAND Europe to undertake a study with the aim to better understand the impact of public policy on innovation. In particular, the objective of the study is twofold: enhance the evidence base around the impact of public policy on research and innovation; explore possible modifications in QUEST III to evaluate a number of innovation policies and reforms. This report focuses on the assessment of the impact of public policies and strategies such as performance-based funding and policies that enhance public-private R&D cooperation on R&D productivity. Furthermore, a satellite model is developed that could be integrated within QUEST III to facilitate evaluation of R&D policies on R&D productivity, innovation and other key macro-economic variables.
