This paper explores the link between mobility and the presence of international research networks. Data come from the GlobSci survey of authors of articles published in 2009 in four fields of science working in sixteen countries. Summary evidence suggests that migration plays an important role...

This paper introduces the special issue on innovation persistence. It delineates three complementary theoretical frameworks assessing drivers and implications of innovation persistence: 'knowledge accumulation' approach, the 'success-breeds-success' hypothesis and the concept of sunk costs in...

We report results from the first systematic study of the mobility of scientists engaged in research in a large number of countries. Data were collected from 17,182 respondents using a web-based survey of corresponding authors in 16 countries in four fields during 2011. We find considerable...

The paper empirically investigates the phenomenon of patent litigation through the analysis of the all population of European patents’ opposition cases in the telecommunication industry. We recover the complete legal history of each dispute and the patent portfolios of the firms involved. We...

This paper contributes to the analysis of the persistence of firm productivity, here measured by the total factor productivity (TFP), and highlights its path dependent characteristics. The study contributes to the literature on persistence in productivity along four main lines. First, it...

Migrant scientists outperform domestic scientists. The result persists after instrumenting migration for reasons of work or study with migration in childhood to minimize the effect of selection. The results are consistent with theories of knowledge recombination and specialty matching.

This paper contributes to the analysis of the persistence of innovation activities, as measured by total factor productivity (TFP), and explores its internal and external determinants stressing its path-dependent characteristics. The external conditions, namely the quality of local knowledge...
