The Diversity of R&D Consortia and Firm Behavior: Evidence from Japanese Data
An empirical analysis of Japanese government-sponsored R&D consortia involving 213 firms over 13 years shows that the diversity of a consortium is associated with greater R&D expenditure by participating firms. Diversity is alternatively measured by the Montgomery (1982) index, based on 3-digit SIC codes, and Branstetter and Sakakibara's (1998) modification of the Jaffe (1986) patent portfolio based index.
