The elusive impact of R&D grants on firm productivity

Abstract

This paper evaluates the effectiveness of R&D subsidies, provided by the European Regional Development Funds, on firms’ productivity. Using detailed longitudinal firm-level data covering the period 2007-2019, we employ state of the art differences-in-differences estimators to evaluate the impacts of R&D grants. Positive causal effects on gross value added and labour productivity are discernible for micro- and small-sized firms participating in co-promotion but not in individual projects. However, these effects seem to be elusive. No evidence of a positive effect of these grants on firm performance for medium- and large-sized firms or for individual R&D projects is found. This investigation contributes to a more comprehensive understanding of the relative effectiveness of productivity enhancement programs.
