Did bank lending stifle innovation in Europe during the Great Recession?

Using the 2008-09 Global Financial crisis and the 2012 Euro area sovereign debt crisis as natural experiments, we investigate the effects of contractions in credit supply on R&D spending in a large sample of European firms. Our identification strategy exploits differences in financial constraints across firms, as well as the cross-industry variation in dependence on external finance, to identify a causal effect of bank credit supply on firm investment in innovation. We show that firms that are more likely financially constrained, in industries more dependent on external finance, have a disproportionally lower growth rate of R&D spending, as well as lower R&D intensity and share of R&D investment in total investment during periods of tight credit supply. These results are robust to different proxies of financial constraints, model specifications and fixed-effects identification strategies.
