Academic Inventors, Scientific Impact and the Institutionalisation of Pasteur's Quadrant in Spain

We rely on a novel database of Spanish author-inventors to explore the relationship between the past patenting experience of academic authors and the scientific impact (citations received and journal prestige) of scientific articles published during 2003–2008 in journals listed in SCOPUS. We also study how such a relationship is affected by differences across academic affiliations, distinguishing between public universities and different types of non-university public research organisations. Our econometric estimations show that scientific impact is positively associated with having authors with past patenting experience as inventors at the European Patent Office. Exceptions are the articles of authors affiliated to new independent public research centres, not tied to the civil service model and oriented to do research that is both excellent and use-inspired. These are also on average the most cited articles.
