Studies of firm-level data have shown that a firm's R&D and the R&D of other firms increase conventional factor productivity. We investigate these phenomena further by examining the relationship between plant-level productivity and firm-level R&D. We find that (1) the productivity-enhancing...

Studies of firm-level data have shown that a firm's Ramp;D and the Ramp;D of other firms increase conventional factor productivity. We investigate these phenomena further by examining the relationship between plant-level productivity and firm-level Ramp;D. We find that (1) the...

We 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...
