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...

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....

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...

This paper presents results from a calibrated welfare model of the UK mobile telephony market which includes many mobile networks; calls to and from the fixed network; networkbased price discrimination; and call externalities. The analysis focuses on the short-run effects of adopting lower...

Switching costs and network effects bind customers to vendors if products are incompatible, locking customers or even markets in to early choices. Lock-in hinders customers from changing suppliers in response to (predictable or unpredictable) changes in efficiency, and gives vendors lucrative ex...

We examine price competition under product-specific network effects, in a duopoly where the products are differentiated horizontally and vertically. When consumers' expectations are not affected by prices, firms may share the market equally, or one firm (possibly the low-quality one) may capture...

Clements (2004) makes the following two claims: (i) unlike direct network effects, increases in the size of the market do not, in the case of indirect network effects, make standardization more likely, but (ii) indirect network effects are associated with excessive standardization. We show in...
