It has long been recognized that worker wages and productivity are higher in large firms. Moreover, economists have been interested in the efficiency of large firms in R&D enterprises. This paper uses inventor panel data to examine the relationship between inventor productivity and firm size in the pharmaceutical and semiconductor industries. In both industries, we find that inventors' productivity increases with firm size even after controlling for inventors' experience, education and other firm characteristics. We find evidence in the pharmaceutical industry that this is partly accounted for by differences in the way in which large and small firms organize R&D activities.
