Bounding the Effects of R&D: An Investigation Using Matched Establishment-Firm Data
AbstractWe find that the effects of parent firm R&D on plant-level productivity are diminished by both the geographic and technological distance between the research lab and the plants; that productivity appears to depend on R&D per plant rather than on the total amount; and that spillovers from technologically related firms are significant but also depend on R&D intensity rather than on total industry R&D. These results suggest that the "dilution" of R&D across multiple target plants reduces its potency sufficiently that spillovers may not be a source of industrywide or economywide increasing returns.
