In this paper we investigate the effects of technological and geographical proximity on knowledge flows in three economic areas: the United States, Japan, and Europe. The contribution to the existing literature is that we introduce a patent inventor approach to measuring the proximity between firms. Generally, patents are attrib- uted to the economic area where firms are located. Here, patents are described on the basis of the distribution of their inventors. The empirical results indicate that there is a statistically significant impact of technological and geographical proximity on knowledge spillovers and that these results are robust with respect to patent office data.

Abstract

In this paper we investigate the effects of technological and geographical proximity on knowledge flows in three economic areas: the United States, Japan, and Europe. The contribution to the existing literature is that we introduce a patent inventor approach to measuring the proximity between firms. Generally, patents are attrib- uted to the economic area where firms are located. Here, patents are described on the basis of the distribution of their inventors. The empirical results indicate that there is a statistically significant impact of technological and geographical proximity on knowledge spillovers and that these results are robust with respect to patent office data.
