Innovation is a crucial driver of urban and regional economic success. Innovative cities and regions tend to grow faster and have higher average wages. Little research, however, has considered the potential negative consequences: as a small body of innovators gain relative to others, innovation...

The purpose of this paper is two-fold. First, we present a model of agglomeration and trade that displays the main features of the recent economic geography literature, while allowing for the derivation of analytical results by means of simple algebra. Second, we show how this framework can be...

We address the fundamental question arising in economic geography: why do economic activities agglomerate in a small number of places? The main reasons for the formation of economic clusters involving firms and/or households are analysed: (i) externalities under perfect competition; (ii)...

This paper constructs a two-region endogenous growth model, where economic geography and public infrastructures play a key role. The model allows us to analyse the contribution of different types of redistributive public policies on growth, industrial geography and spatial income distribution....

Paul Krugman has clarified the microeconomic underpinnings of both spatial economic agglomerations and regional imbalances at national and international levels. He has achieved this with a series of remarkably original papers and books that succeed in combining imperfect competition, increasing...

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...

This paper looks at the genesis of innovation in the United States from a territorial perspective. The analysis aims to disentangle the impact of local R&D expenditure from other contextual conditions supportive of the process of innovation. Particular emphasis is devoted to the role of...

This paper analyses the geography of innovation in China and India. Using a tailor-made panel database for regions in these two countries, we show that both countries exhibit increasingly strong polarisation of innovative capacity in a limited number of urban areas. But the factors behind this...

Transport infrastructure has represented one of the cornerstones of development and cohesion strategies in the European Union (EU) and elsewhere in the world. However, despite the considerable funds devoted to it, its impact remains controversial. This paper revisits the question of to what...
