This paper is a first attempt towards the full inclusion of a group of variables greatly studied in the current literature on innovation and industrial economics -such as knowledge links and the structure of competition and collaboration in a sector -into the determinants of the international...

The analysis of innovation and the evolution of industries evolution has witnessed major progress in several areas. Contributions at the empirical, appreciative, econometric and modelling levels have greater advanced our understanding of innovation, industrial dynamics and the different...
