This paper addresses the productivity effects of R&D spillovers through imports, foreign direct investment and domestic intermediates, using a highly disaggregated data set for Norwegian business sectors. The paper analyzes the importance of absorptive capacity effects, claiming that the positive contribution from R&D spillovers is an increasing function of the R&D activities of the economic units that receive the spillovers. The paper finds strong support for the existence of R&D spillovers through imports and domestic intermediates and identifies absorptive capacity effects relating to spillovers from imports.
