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.
