The knowledge production of 'R' and 'D'

Economics Letters, 2009, vol. 105, issue 1, 141-143

Abstract: Many studies investigate the relationship between R&D and patents applying knowledge production functions. Using aggregated R&D may underestimate the productivity of 'R', as mainly 'R' but not 'D' leads to patents. Disaggregating 'R' and 'D' shows a significant premium of 'R' towards patenting.
