Knowledge Spillover Agents and Regional Development

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.

Our findings show that these phenomena are highly uneven in nature, benefiting only a few countries which are capable to act as magnet for scientific talent
