Spillovers from publicly financed business R&D: some empirical evidence from Germany

This paper investigates the effects of interindustry R&D spillovers from publicly financed business R&D on private R&D efforts and productivity using data of West German manufacturing industries. The results suggest that it is important to distinguish between the effects of spillovers from privately and publicly financed business R&D. In particular, estimation results provide evidence of productivity-enhancing effects of spillovers from privately financed R&D while results are less clear-cut for publicly financed R&D. Moreover, there is some empirical evidence that private R&D efforts of higher-technology industries are stimulated by spillovers from privately financed R&D but not by spillovers from publicly financed R&D. However, public funding of R&D in higher-technology industries seems to induce private R&D investments within these industries.

Is commercialization good or bad for science? Individual-level evidence from the Max Planck Society

Based on new data, this paper studies the invention disclosure, licensing, and spin-off activities of Max Planck Institute directors over the time period 1985-2004, analyzing their effects on the scientists’ subsequent publication and citation records. Consistent with prior findings, inventing does not adversely affect research output. Mixed results are obtained with regard to commercialization activities. The analysis suggests qualifications to earlier explanations of positive relationships between inventing and publishing.

R&D strategies and entrepreneurial spawning

This paper analyzes how different R&D strategies of incumbent firms affect the quantity and quality of their entrepreneurial spawning. When examining entrepreneurial ventures of ex-employees of firms with different R&D strategies, three things emerge: First, firms with persistent R&D investments and a general superiority in sales, exports, productivity, profitability and wages are less likely to generate entrepreneurs than firms with temporary or no R&D investments. Second, start-ups from knowledge intensive business service (KIBS) firms with persistent R&D investments have a significantly increased probability of survival. No corresponding association between the R&D strategies of incumbents and survival of entrepreneurial spawns is found for incumbents in manufacturing sectors. Third, spin-outs from KIBS-firms are more likely to survive if they start in the same sector, indicating the importance of inherited knowledge. These findings suggest that R&D intensive firms are less likely to generate employee start-ups, but their entrepreneurial spawns tend to be of higher quality.
