Productivity spillovers of R&D in Sweden
(English)Manuscript (preprint) (Other academic)
Although Sweden is one of the most R&D-intensive OECD countries, the importance of R&D spillovers in the country has not been systematically analyzed. This paper employs a cross sectional dataset of 264 R&D performing Swedish firms in 1996-97. With this set, knowledge production functions are estimated, in which industry groups are treated as subsamples. In addition, 160,614 non-R&D performing firms are used to examine the effects of R&D spillovers also among non R&D performers.
The estimations use three different weight methods for R&D that spills over from other industries: two input—output measures and a technology flow matrix in the spirit of Jaffe (1986). The results indicate that R&D performing firms gain in Total Factor Productivity from their own R&D. In two of the three weighing matrices spillovers from R&D result in higher Total Factor Productivity among R&D performers. Among non-R&D performers, the Total Factor Productivity effect of R&D spillovers is robustly positive and significant across specifications. Examination of the social returns to R&D from specific industries, one at a time, to other industries does not reveal substantial social effects beyond the effect on the own firm. It is reasoned that the most likely reason for the small size of R&D spillovers rests in the Swedish corporate structure, with most R&D being conducted by large multinationals.
