Abstract: We study the effect of the interfirm mobility of prolific inventors on their patent productivity (measured by their number of patents filed with the USPTO). The analysis covers three countries: France, the United Kingdom and Germany. Unlike the literature on the subject which deals with mobility in a generic way we distinguish two types: external mobility when the inventor develops a patent on behalf of a company with which he had never worked in the past; internal mobility when the inventor changes companies but returns to one of those with which he has already worked. We show that the average level of mobility would have a positive and significant but small effect. On the other hand, we show that the balance between internal and external mobility has a much greater effect on the productivity of researchers than its average level: more external mobility would significantly degrade productivity while more internal mobility would significantly increase productivity.
