In this paper we explore the relationship between the size of a country, the size of its cities, and the economic performance of the country. In order to do this we integrate three different literature, namely the literature on optimal country size, literature on historical processes of...

We assess the efficiency of regional innovation systems (RIS) in Germany by means of a knowledge production function. This function relates private sector research and development (R&D) activity in a region to the number of inventions that have been registered by residents of that region....

Innovation processes are characterized by a pronounced division of labor between actors. Two types of externality may arise from such interactions. On the one hand, a close location of actors affiliated to the same industry may stimulate innovation (MAR externalities). On the other hand, new...

The Patentatlas by Greif and Schmiedl (2002) represents an important source for patent data in Germany. Its use for industry-specific studies is however problematic because the correct assignment of patent data classified by technological fields to commonly used industry classifications is...

We study location choices and firm performance in the German machine tool industry, focusing on the forced migration of East German firms after World War II. Our analysis of location choices supports earlier findings that industry agglomerations attract further entrants. Relocating firms...

We analyze the regional distribution and the effect of people in creative occupations based on data for more than 450 regions in eight European countries. The geographic distribution of the creative class is highly uneven. The creative class is not attracted to highly urbanized regions per se,...

In his oft-cited "What do we know about entry?", Paul Geroski (1995) gave a survey of empirical works on this central topic regarding industrial organization and, more precisely, market dynamics. Surprisingly, his article remains silent on the spatial dimension of these dynamics. This paper...

This study analyzes the relationship between the specialization of a region in certain industries and the efficiency of the region in generating new knowledge. The efficiency measure is constructed by relating regional R&D input and output. An inversely u-shaped relationship is found between...

Studies analyzing the importance of intra- and inter-regional cooperation for regional innovation performance are mainly of qualitative nature and focus strongly on the positive effects that high levels of cooperation can yield. For the case of the German labor market regions and the Electrics &...

Industrial clusters develop regionally along the industry's lifecycle and typically exist over many product generations. In order to maintain their innovativeness, they have to develop and adjust along the industry lifecycle. We conduct 142 depth face-to-face interviews in clusters across two...
