<b>RESUMEN:</b><br> <br> Las spin-off universitarias constituyen un importante potencial para el desarrollo económico y social de un territorio. En el presente trabajo se aborda la importancia económica de estas entidades y su contribución a la creación de riqueza en el ámbito andaluz. Se analizan las...

This paper explores the effects of distance as well as subnational and national borders on international and intranational knowledge spillovers through patent citations across the 39 most patent-cited countries and 319 metropolitan statistical areas (MSAs) within the U.S. In contrast to previous...

Using patent citation data for the U.S., we test whether knowledge spillovers in biotechnology are sensitive to distance, and whether that sensitivity has changed over time. Controlling for self-citation by inventor, assignee and examiner, cohort-based regression analysis shows that physical...

Innovative firms often engage in knowledge interactions across regional boundaries, which is difficult to account for by territorial innovation models. The territorial knowledge dynamics perspective directs attention to the ways in which firms and other actors combine regional and extra-regional...

Using over 250,000 U.S. patent citations, we test whether knowledge transfers in the energy sector are sensitive to distance, and whether that sensitivity has changed over time. Controlling for self-citation by inventor, assignee and examiner, multivariate regression analysis shows that physical...

Usually, the diffusion of a non-rival market knowledge externality - called a Knowledge Spillover (KS) - is related to geographical proximity. In this paper we explore the channels through which knowledge spreads. Compared with earlier work on KS measures, this study makes a step forward by...

This paper investigates whether knowledge transferred from different sources matter differently for carrying out different innovation outcomes, using a firm-level dataset collected in the Pearl River Delta (PRD) in China. It also investigates whether companies in the PRD in China tend to...

Previous research on market economies characterized by stable framework conditions shows that several regional factors determine start-up activity. Not much is known about what drives entrepreneurship in unstable environments characterized by significant institutional changes that affect the...

The diffusion of knowledge in the world generates positive externalities if knowledge flows increase the productivity of R&D. Our work analyzes knowledge diffusion and knowledge externalities in generating innovation and in determining productivity. We first estimate the determinants of...

The development of inventor networks is characterized by the addition of a significant number of new inventors, while a considerable number of incumbent inventors discontinue. We estimate the persistence of knowledge in regional inventor networks using alternative assumptions about knowledge...
