The Knowledge Production of 'R' and 'D'
Thorwarth, Susanne; Kraft, Kornelius; Czarnitzki, Dirk - 2008
Many studies investigate the relationship between R&D expenditures as an input and patents as an intermediate product or output of a knowledge production function. We suggest that the productivity of research in patent production functions has been underestimated in the literature, as scholars...
