Technological entry, exit and survival: an empirical analysis of patent data

Article Abstract:

Empirical data are presented on the patterns of technological entry and exit across sectors and over time. The examination is based on patent data from the European Patent Office for 49 technological classes in the US, Japan, Germany, UK, France and Italy, over the period 1978-1991. It was observed that innovative turbulence is significant and that it is a composite phenomenon, in which real innovative entrants/exiters and lateral entrants/exiters have different roles. Moreover, it was seen that most of the entrants are occasional innovators, while persistent innovators are few in number but large in terms of patents.

Quandaries in the economics of dual technologies and spillovers from military to civilian research and development

Article Abstract:

The prevailing belief that military research and development contribute little to the civilian sector is incorrect because it does not take into account a technology's lifecycle and whether a technology is product- or process-oriented. In addition, the 'social networks within which the technologies are developed and used' impact any potential cross-benefits. Patterns of potential duality, however, emerge
