摘要
This paper examines the inventive performances of a regional set of Italian inventors. After stressing that the distribution of the inventors' productivity is extremely skewed, we find that patent productivity is not influenced by individual characteristics, but it is higher for the inventors working in teams or in large firms with greater patent portfolios. Instead, patent quality is associated with some individual features such as age, gender and level of education. Accordingly, patented innovations coming from inventors working in small firms or independently can be as valuable as those generated in large companies. The policy implications of these findings are discussed. (C) 2013 Society for Policy Modeling. Published by Elsevier Inc. All rights reserved.
