considerable number of incumbent inventors discontinue. We estimated the persistence of knowledge in the inventor networks of nine … German regions using alternative assumptions about knowledge transfer. Based on these estimates, we analyzed how the size and … structure of a network may influence knowledge persistence over time. In a final step, we assessed how persistent knowledge as …

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 …

We investigate the role of universities as a knowledge source for regional innovation processes. The contribution of …

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 …

Setting up an innovative new firm is a way of commercializing knowledge. The paper gives an overview of the extent of … new firm formation in knowledge intensive and in innovative German industries and their development. The founding of a new …

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 …
