April 2015Assets with "Warts": How Reliable is the Market for Technology?
with Matthew J. Higgins, Marco Ceccagnoli: w21103
Existing research has focused on why and when firms may choose to access the external technology market. Surprisingly, however, less is known about the reliability of the patents attached to these external technologies in the face of litigation. “Weak” external patents expose a firm to the potential loss of downstream revenues. To address this question we construct a novel dataset of patent litigation in the pharmaceutical industry. We exploit a change in U.S. patent law as a natural experiment to test whether external patents are more reliable than those developed internally. We find that acquired patents are more likely to fall during litigation; they are less reliable then internal technologies. Losses lead to an average reduction in market capitalization of $450 million. Overall, our r...
February 2013Behind the Scenes: Sources of Complementarity in R&D
with Marco Ceccagnoli, Matthew J. Higgins: w18795
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...
