R & D Spillovers and Recipient Firm Size

What type of enterprise forges close links with universities and government labs? Evidence from CIS 2

“…Previous studies have found that small firms benefit more from university-based research spillovers than large firms, who rely more on their own R&D (Link and Rees (1990), Acs et al (1994), Vivarelli (1994), Feldman (1994)). Our results are inconclusive in this regard, as we find that both larger size and more R&D are correlated with more sourcing of knowledge from universities.…”

Is Canadian intellectual property leaving Canada? A study of nanotechnology patenting

“…Localized knowledge spillovers are frequently claimed to be a key explanatory factor for the geographical concentration of innovative activity (Dahl and Pedersen, 2004). This phenomenon is explained by Jaffe (1989), Acs et al (1992Acs et al ( , 1994, who suggest that investments in R&D by private corporations and universities spill over for third party firms to exploit. Since it is presumed that the transmission of knowledge is distance sensitive, the ability to receive knowledge spillovers is influenced by the distance from the knowledge source, which was also empirically confirmed by Jaffe et al (1993) who proposed that knowledge spills over locally and takes time to diffuse across geographical distance.…”

Does Cluster Policy Trigger R&D Activity? – Evidence from German Biotech Contests

“…4 While the positive effects of local agglomeration on knowledge intensive industries might be clear from a theoretical point of view, it is not easy to identify empirically the causal effect of geographical proximity on R&D activity. Starting from the influential work of Acs et al (1993), Jaffe et al (1993), Audretsch and Feldman (1996) and Anselin et al (1997), there is a growing literature identifying the transmission channels from clustered firms to enhanced R&D, innovation activity and finally productivity growth. Acs et al (1993), for instance, estimate production functions for US data and find that, beside standard input factors, the geographical position in a cluster matters strongly.…”

Jaffe et al (1993) find that the probability of an inventor to be cited in a patent application is larger if the actors are located in geographical proximity.…”
