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 …

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 …

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 …

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 … pure size is unimportant. Therefore, a policy that wants to promote regional innovation processes by building up …

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 investigate the role played by different fields of academic knowledge and various types of higher education … different indicators for these types of knowledge, the strongest effects are found for the number of professors, followed by the … the regional knowledge stock than the number of students that is most important for the emergence of innovative stat-ups. …
