This paper examines the links between the rhythm of knowledge generation, the types of actors involved in knowledge generation and the structure of networks of collaborations in the biotech sector. The analysis departs from all biotechnology patent applications covered by Derwent Biotechnology...

This paper focuses on the evolution of the telecommunications industry. Within the economic literature, different analytical assumptions are proposed, from a global sustainability of competition to the re-emergence of a stable oligopoly generated by a process of shakeout through mergers and...

L'analyse économique offre deux visions distinctes de la notion de concurrence, que l'on peut faire correspondre plus largement à deux écoles d'appréhension des phénomènes économiques. Dans l'analyse traditionnelle, tout d'abord, la concurrence est définie et étudiée comme un état du...

Diverse theories of industry dynamics predict heterogeneity in production efficiency to be the driver of firms' growth, survival and industrial change, either through a direct link between efficiency and growth, or through an indirect effect via profitabilities, as more productive firms can...

Contemporary economic analysis is largely subject to rather bizarre schizofrenic syndromes. On the one hand, over the last thirty years or so, macro theories have tried to squeeze the interpretation of whatever aggregate dynamics down to some sort of decision-theoretic framework in which the...

Empirically the diffusion of competing technologies most often displays either "lock-in" to a quasi-monopoly or apparent turbulence but rarely stable market-sharing. In contrast with widespread views, we show that, first, unbounded increasing returns are neither necessary nor sufficient to lead...
