Even though management consultants increasingly recommend that in-house research be outsourced, little is known about the conditions favoring substitution or complementarity between internal R&D and external technology acquisition. In this paper, we attempt to provide a deeper understanding of the firm-level drivers of complementarity between these two types of investments through the structural estimation of a flexible innovation production function, such as the translog. Our empirical analysis is based on a unique panel dataset on the R&D and in-licensing expenditures of 94 global pharmaceutical firms active in drug development between 1997 and 2005. Our results suggest that internal R&D and in-licensing in the pharmaceutical industry were neither complements nor substitutes during the s...

We analyze the effect of patenting on R&D with a model linking a firm's R&D effort with its decision to patent, recognizing that R&D and patenting affect one another and are both driven by many of the same factors. Using survey data for the U.S. manufacturing sector, we estimate the increment to the value of an innovation realized by patenting it, and then analyze the effect on R&D of changing that premium. Although patent protection is found to provide a positive premium on average in only a few industries, our results also imply that it stimulates R&D across almost all manufacturing industries, with the magnitude of that effect varying substantially.
