Do universities knowledge spillovers impact on new firm's growth? Empirical evidence from UK

The paper explores the effect of scientific institutions on firm's growth, coupling regional science and entrepreneurship approaches. We focus on the role of universities, largely considered in the literature as the main source of knowledge spillovers. To this purpose, we centre our attention on UK public companies on the Alternative Investment Market (AIM), a market dedicated to young and growing companies in both science and non-science based industries. In the paper we investigate the growth determinants of 231 listed firms which have gone public during the period going from 1995 to 2006. To our purposes, in the empirical analysis we use the Gibrat's Law of Proportionate Effects model. The results supports the hypothesis that, controlling for firm's idiosyncratic factors and external forces, both universities knowledge input and output are important determinants of the growth of entrepreneurial firms listed on the AIM. © 2008 Springer Science + Business Media, LLC.
