Using a newly assembled dataset of U.S. patents, we show that overall innovation activity is less concentrated in high-density urban areas than commonly believed, but inventions based on atypical combinations of knowledge are indeed more prevalent in high-density cities. To interpret this...

Many regions on the EU Eastern borders have developed favourably after the opening up of the border and the implementation of association agreements with the CEECs. This was often seen as a positive sign for the further perspectives of these regions after EU enlargement. In this paper we take a...

Much has been written on the success of the Indian software industry, enumerating systemic factors like first-class higher education and research institutions, both public and private; low labour costs, stimulating (state) policies etc. However, although most studies analyzing the 'Indian'...

Entrepreneurship is a local and dynamic phenomenon. We jointly investigate spatial spillovers and time persistence of regional new business formation. Using panel data from all 402 German counties for 1996-2011, we estimate dynamic spatial panel models of business creation in the high-tech and...

The relationship between innovation and firm survival is analyzed for the population of German laser source producers from the beginning of the industry until 2005. Innovation effort is approximated by the generation of high quality patents in laser sources technology (IPC H01S) and by having...

To quickly adapt to technological change and developments, and thus remain competitive, firms increasingly resort to the use of external technology. This paper investigates whether and to what extent the acquisition of external disembodied technology affects the efficiency and productivity in...

The innovative performance of 1,200 representative firms in the Czech Republic, Germany, Hungary, Poland, Romania and the Slovak Republic was analyzed. The study differentiates between product innovation and three different forms of process innovations. This data was joined to the quality of...

Cluster studies have shown that innovation can be understood as the result of an inter- organizational process, where a division of labor with regard to exploration and exploitation exists among the actors inside the cluster. A cluster is ambidextrous if it manages to balance innovative...

This paper presents evidence on the spatial distribution and effects of urban agglomeration on firm innovation. It uses a unique dataset that consistently defines city boundaries and identifies firms' innovation-related activities across 25 developing countries in Asia. We find firm innovation...
