November 2015Get With the Program: Software-Driven Innovation in Traditional Manufacturing
with Lee G. Branstetter, Namho Kwon: w21752
This paper documents the increasing importance of software for successful innovation in manufacturing sectors well beyond the traditional definition of electronics and information technology. Using panel data for 229 publicly listed firms from 18 countries across four manufacturing industries over the period 1981-2005, we find significant variation across firms in the software intensity of their innovative activity. Firms that exhibit a higher level of software intensity generate more patents per R&D dollar, and their investment in R&D is more highly valued by equity markets. We present evidence that geographic differences in the abundance of skilled software labor are an important factor in determining sample firms’ software intensity and performance.
July 2010Going Soft: How the Rise of Software Based Innovation Led to the Decline of Japan's IT Industry and the Resurgence of Silicon Valley
with Ashish Arora, Lee G. Branstetter: w16156
This paper documents a shift in the nature of innovation in the information technology (IT) industry. Using comprehensive data on all IT patents granted by the USPTO from 1980-2002, we find strong evidence of a change in IT innovation that is systematic, substantial, and increasingly dependent on software. This change in the nature of IT innovation has had differential effects on the performance of the IT industries in the United States and Japan. Using a broad unbalanced panel of US and Japanese publicly listed IT firms in the period 1983-1999, we show that (a) Japanese IT innovation relies less on software advances than US IT innovation, (b) the innovation performance of Japanese IT firms is increasingly lagging behind that of their US counterparts, particularly in IT sectors that are m...
