When labour market rigidities are useful for innovation. Evidence from German IAB firm-level data

Supply-side economists made numerous pleas for removing labour market rigidities through 'structural reforms'. From a Schumpeterian viewpoint, however, one can argue that labour market rigidities create useful incentives for innovation. Our estimates on German panel data (2007-2015) support the Schumpeterian view. Using the taxonomy of industries by Peneder (2010) we find that evidence of the Schumpeterian view is particularly strong in R&D intensive manufacturing industries, as well as in service industries with high degrees of cumulativeness of knowledge. Evidence of the Schumpeterian view is weaker in low-technology industries and in start-ups when firms rely more on generally available knowledge rather than on firm-specific and tacit knowledge accumulated in the past.
