knowledge of new inventors effect the performance of regional innovation systems (RIS). The results suggest that the knowledge … considerable number of incumbent inventors discontinue. We estimate the persistence of knowledge in regional inventor networks … using alternative assumptions about knowledge transfer. Based on these estimates we analyze how the size and structure of a …

We investigate the contribution of different inputs, particularly different knowledge sources, on regional patenting … output in the framework of a knowledge production function. The knowledge sources included are R&D employment, size of public … departments, German Science Foundation (DFG), and from other sources. The contribution of these knowledge sources is tested …

We analyze the spatial diffusion of knowledge in laser technology in West Germany from 1960, when this technology began … of laser knowledge was especially prevalent in large agglomerations. While we cannot detect knowledge spillovers from … research later, indicating the accumulation of knowledge generated in previous periods. Our results highlight the role of a …

We measure the efficiency of regional innovation systems (RIS) in Germany by means of a knowledge production function … second approach assesses regional differences within the framework of a stochastic frontier knowledge production function …. This approach mainly reveals differences with regard to the intercept of the knowledge production function and, therefore …

the knowledge in laser technology was particularly high in those regions which have started laser research rather early …. There is also no significant effect of regional knowledge in the field of laser technology on the number of regional laser …

We assess the efficiency of regional innovation systems (RIS) in Germany by means of a knowledge production function … efficiency of its innovation system is inversely u-shaped. Regions dominated by large establishments tend to be less efficient …
