Abstract

This paper investigates the existence and nature of knowledge-spillovers at the micro-level and, in turn,the capacity of firms to absorb new ideas generated in R&D laboratories. It evaluates the merits for a firmof attracting or retaining “key” inventors, or assembling a wide team of inventors. First, using the EPO-OECD data, we identify “key” and “normal” inventors by means of the Hill’s estimator. Then, we test thehypothesis that the presence of one “key” inventor in a firm’s R&D laboratory would have a positive effecton the Italian firms output. Our results are threefold: 1) the patent portfolio positively affects the valueof production; 2) the simple presence of “key” inventors in a R&D laboratory does not significantly affectthe output; 3) for a given number of patent applications by firm, a less concentrated patents distributionacross inventors employed in the same R&D laboratory makes a positive impact on the production.
