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...

Should constraints on urban expansion be relaxed because of external agglomeration economies? In a system of heterogeneous cities, we demonstrate that second-best land use policy consists of a tax on city creation and a subsidy (tax) on urban development in cities in which the marginal-average...

There is a substantial empirical literature quantifying the positive relationship between city size and productivity. The paper draws out the implications of this productivity relationship for evaluations of urban transport improvements. A theoretical model is developed and used to derive a...

This paper presents evidence that high speed rail systems, by bringing economic agents closer together, sustainably promote economic activity within regions that enjoy an increase in accessibility. Our results on the one hand confirm expectations that have led to huge public investments into...

This paper surveys the theoretical and empirical literature on the relationship between the spatial distribution of economic activity and transportation costs. We develop a multi-region model of economic geography that we use to understand the general equilibrium implications of transportation...

The striking geographical concentration of economic activities suggests that there are substantial benefits to agglomeration. However, the nature of those benefits remains unclear. In this paper we take advantage of a new dataset to quantify the role of one of the main contenders - the matching...

Explaining the growth and change of regions and cities is one of the great challenges for social science. The field of economic geography and associated economics has developed frameworks in recent years that, while tackling major questions in spatial economic development, are deficient in their...

Research on entrepreneurship often uses information on self-employment to proxy for business creation and innovative behaviour. However, little evidence has been collected on the link between these measures. In this paper, we use data from the UK Labour Force Survey (LFS) combined with data from...
