This paper aims at contributing to the research on knowledge spillovers and their spatial extent by presenting new empirical evidence on a key mechanism driving and directing knowledge diffusion processes, namely the mobility of knowledge and highly skilled workers. The analysis is based on a rich data set on US inventors and their patents filed at the European Patent Office from 1978 to 2004. Findings indicate that two distinctive spatial patterns can be detected: inventors move both at short and large spatial distances (i.e. three hours and more than 8 hours driving distance, respectively) in similar proportions. Interestingly, in the largest innovative urban areas inventors' inflows and outflows primarily involve distant rather than neighbour areas.

Abstract

This paper aims at contributing to the research on knowledge spillovers and their spatial extent by presenting new empirical evidence on a key mechanism driving and directing knowledge diffusion processes, namely the mobility of knowledge and highly skilled workers. The analysis is based on a rich data set on US inventors and their patents filed at the European Patent Office from 1978 to 2004. Findings indicate that two distinctive spatial patterns can be detected: inventors move both at short and large spatial distances (i.e. three hours and more than 8 hours driving distance, respectively) in similar proportions. Interestingly, in the largest innovative urban areas inventors' inflows and outflows primarily involve distant rather than neighbour areas.
