چکیده
This paper looks at the link between inter-regional mobility, innovation and firms’ behavioural heterogeneity in their reliance on localised external sources of knowledge. By linking patent data (capturing inventors’ inter-regional mobility) with firm-level data (providing information on firms’ innovation inputs and behaviour) a robust identification strategy makes it possible to shed new light on the geographical mobility-innovation nexus. The analysis of English firms suggests that firm-level heterogeneity – largely overlooked in previous studies is the key to explain the innovation impact of interregional mobility over and above learning-by-hiring mechanisms. A causal link between inflows of new inventors into the local labour market and innovation emerges only for firms that make the use of external knowledge sources an integral part of their innovation strategies.
