Faster technological progress has long been considered a key potential benefit of agglomeration. Physical proximity to others may help inventors adopt new ideas in their work by increasing awareness about which new ideas exist and by enhancing understanding of the properties and usefulness of...

Which structural reforms affect the speed the regional convergence within a country? We found that domestic financial development, trade/current account openness, better institutional infrastructure, and selected labor market reforms facilitate regional convergence. However, these reforms have...

We in this paper assess the impacts of technological change on China's regional disparities using a general equilibrium model of multiple regions and multiple sectors. We use the most recent available Chinese interregional data to calibrate the model parameters for 1987 and 2000. We then assess...

Fifteen years after German reunification, the facts about slow regional convergence have born out the prediction of Barro (1991), except that migration out of East Germany has not slowed down. I document that in particular the 18-29 year old are leaving East Germany, and that the emigration has...

We present a theory of spatial development. Manufacturing and services firms located in a continuous geographic area choose each period how much to innovate. Firms trade subject to transport costs and technology diffuses spatially across locations. The result is a spatial endogenous growth...

Internet development holds the promise of transmitting economic value across physical space at zero marginal cost. In such a 'weightless economy', what factors matter for the location of economic activity and thus for economic development? This paper sketches a model of spatial dynamics over a...

We examine variation in the concentration of inventive activity across 72 of North America's most highly innovative locations. In 12 of these areas, innovation is particularly concentrated in a single, large firm; we refer to such locations as "company towns.'' We find that inventors employed by...

What are the consequences of resource-based regional specialization, when it persists over a long period of time? While much of the literature argues that specialization is beneficial, recent work suggests it may be costly in the long run, due to economic or political reasons. I examine this...

We present a theory of spatial development. A continuum of locations in a geographic area choose each period how much to innovate (if at all) in manufacturing and services. Locations can trade subject to transport costs and technology diffuses spatially across locations. The result is an...

Theories of economic growth at the regional and national level, have expanded the traditional production function of the Solow model towards a wide function that collects conditioning factors of labour productivity, measured by R & D expenditure, the number of patents, the human capital, the...
