Knowledge Spillover Agents and Regional Development: Spatial Distribution and Mobility of Star Scientists

It is widely recognised that knowledge and highly skilled individuals as “carriers” of knowledge (i.e. knowledge spillover agents) play a key role in impelling the development and growth of cities and regions. In this paper we discuss in a conceptual way the relation between spatial movements of talent and knowledge flows and present empirical results on the geography and mobility patterns of star scientists. Our findings show that these phenomena a highly uneven in nature, benefiting only a few countries which are capable to act as magnet for scientific talent.
