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...

Since the early 1990s, there has been a renaissance in the study of regional growth, spurred by new models, methods and data. We survey a range of modelling traditions, and some formal approaches to the ’hard problem’ of regional economics, namely the joint consideration of agglomeration and...

We show in the framework of a new economic geography model that when labor is heterogenous and productivity depends on the quality of the match between job and worker, trade liberalization may lead to industrial agglomeration and inter-industry trade. The agglomeration force is the improvement...

We show in the context of a new economic geography model that when labor is heterogenous trade liberalization may lead to industrial agglomeration and inter-regional trade. Labor heterogeneity gives local monopoly power to firms but also introduces variations in the quality of the job match....

Foregone benefits of the open space that is sacrificed through urban sprawl are hard to quantify. We obtain a simple benchmark measure by introducing a demand for trips beyond the urban boundary into the monocentric city model. The externality arises from the increase in travel costs that...

Does brownfield redevelopment warrant government support? We explore several external benefits in an urban general equilibrium framework. Preferences are modelled such that demand for housing units in the city is downward sloping, which yields a more general setup than the extreme open and...

This paper analyses patterns of production across 14 industries in 45 regions from 7 European countries since 1975. We estimate a structural equation derived directly from Heckscher- Ohlin theory that relates an industry’s share of a region’s GDP to factor endowments and relative prices....

This paper estimates the impact of road improvements on firm employment and productivity using plant level longitudinal data for Britain. Exposure to transport improvements is measured by changes in employment accessibility along the road network. These changes are constructed using data on...

The paper decomposes a geographical concentration index to examine the temporal scope of a spillover, which is the period of time over which one firm’s activity directly affects the location of other firms’ activities. Natural advantages are fixed over reasonably long time periods, but if...

This article 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 polarization of innovative capacity in a limited number of urban areas. But the factors behind this...
