| Abstract: | Are scientific arguments used for analysing "sustainable development" ? This issue is at the core of the EBP-biosoc research project of which we present a few aspects on the use of scientific knowledge through "Evidence Based Policy" method. The use of such a framework in social sciences requires taking account of pluralism of approaches in order to have an idea of the validity spectrum of the possible empirical knowledge to be exploited. The notion of research programme of Lakatos can give an account of pluralism inside a given discipline. This contribution gives a presentation of EBP method and proposes a sketching out of its application to social sciences through an attempt to characterise the regulation school theory with the Lakatosian concepts, which gives clues about the type of empirical knowledge that can be expected from this framework. Al last, this is applied to the link between agriculture and economic cohesion. |

| Abstract: | This article compares the relationship between patent quality and patent value in discrete and cumulative innovation. Using factor analysis and a set of various commonly used patent quality indicators including claims, citations and family size, we build a quality factor jointly driving all indicators for 9255 patents. We then test the significance of this quality factor for predicting patent renewal after 4, 8 and 12 years in an ordered logistic regression. Whereas we establish a robust and significant link between patent quality and value in samples of discrete and complex technology patents, there is no significant link for patents that are essential to technological standards. Consistently, neither the quality factor nor any single indicator allows predicting litigation on an essential patent. We conclude that while there is a robust link between patent quality and value in discrete innovation, this link is much weaker in cumulative innovation. Nevertheless, this affects only narrow, yet highly relevant, technological fields. There is no evidence that cumulativeness affects the relationship between quality and value in whole technological classes classified as “complex” by the literature. |

| Abstract: | We analyze the emergence and spatial evolution of the German laser systems industry. Regional knowledge in the related field of laser sources, as well as the presence of universities with physics or engineering departments, is conducive to the emergence of laser systems suppliers. The regional presence of source producers is also positively related to entry into laser systems. One important mechanism behind regional entry is the diversification of upstream laser source producers into the downstream systems market. Entry into the materials processing submarket appears to be unrelated to academic knowledge in the region, but the presence of laser source producers and the regional stock of laser knowledge are still highly predictive in this submarket. |
