Geographic and Technological R&D Spillovers within the Triad: Micro Evidence from US Patents

Working Paper: CEPR ID: DP7113

Authors: Luigi Aldieri; Michele Cincera

Abstract: This paper aims at assessing the magnitude of R&D spillover effects on large international R&D companies? productivity growth. In particular, we investigate the extent to which R&D spillover effects are intensified by both geographic and technological proximities between spillover generating and receiving firms. We also control for the firm?s ability to identify, assimilate and absorb the external knowledge stock. The results estimated by means of panel data econometric methods (system GMM) indicate a positive and significant impact of both types of R&D spillovers and of absorptive capacity on productivity performance.
