We exploit a unique panel of 75 metro areas (‘cities’) across the globe and employ a cityfixed effects model to identify the determinants of within-city changes in air pollution concentration between 2005 and 2011. Increasing car and population densities significantly reduce air pollution...

We present a modified open monocentric city model that assumes that land is available for conversion into new housing throughout the city. The model predicts that positive local income shocks (i) increase the city’s share of multi-family housing in new construction and (ii) lead to the...

A simple model of offshoring is used to integrate the complex gallery of results that exist in the theoretical offshoring/fragmentation literature. The paper depicts offshoring as ‘shadow migration’ and shows that this allows straightforward derivation of the general equilibrium effects on...

The Long-Term Consequences of Regional Specialization* 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,...

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...
