This paper investigates how physical, organisational, institutional, cognitive, social, and ethnic proximities between inventors shape their collaboration decisions. Using a new panel of UK inventors and a novel identification strategy, this paper systematically explores the net effects of all...

The rate of regional growth of new knowledge in the field of nanotechnology, as measured by counts of articles and patents in the open-access digital library NanoBank, is shown to be positively affected both by the size of existing regional stocks of recorded knowledge in all scientific fields,...

Over the last few decades, territorial approaches have generally tried to explain how regions have specialised their production systems around specific path dependencies and technological innovation; how their specialisation enabled them to compete locally in the global market. Some...

This paper addresses the issue of updating a research agenda about territorial innovation models (TIMs) such as innovative milieus, industrial districts, regional innovation systems, etc. The theoretical shift from innovation studies to the knowledge economy is taken into account by the...

The geographical sources of innovation of firms have been hotly debated. While the traditional view is that physical proximity within city-regions is key for the innovative capacity of firms, the literature on ‘global pipelines’ has been stressing the importance of establishing communication...

We examine the relationship between the diffusion of advanced internet technology and the geographic concentration of invention, as measured by patents. First, we show that patenting became more concentrated from the early 1990s to the early 2000s and, similarly, that counties that were leaders...

The geography of innovation describes the importance of proximity and location to innovative activity. As part of what has been termed the new economic geography, this area of research is less than 20 years old, and is now developed sufficiently so that the discussion can be organized around...

In this chapter, we analyze immigration and its effect on urban and regional economies focusing on productivity and labor markets. While immigration policies are typically national, the effects of international migrants are often more easily identified on local economies. The reason is that...

We investigate the impact of the Golden Quadrilateral (GQ) highway project on the Indian organized manufacturing sector using enterprise data. The GQ project upgraded the quality and width of 5,846 km of roads in India. We use a difference-in-difference estimation strategy to compare non-nodal...

We estimate the effects of major roads and public transit on the growth of major cities in the US between 1980 and 2000. We find that a 10% increase in a city’s stock of roads causes about a 2% increase in its population and employment and a small decrease in its share of poor households over...
