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...

After the fall of the Roman Empire, urban life in France became a shadow of its former self, but in Britain it completely disappeared. Guy Michaels and Ferdinand Rauch use these contrasting experiences as a natural experiment to explore the impact of history on economic geography - and what...

Do locational fundamentals such as coastlines and rivers determine town locations, or can historical events trap towns in unfavourable locations for centuries? We examine the effects on town locations of the collapse of the Western Roman Empire, which temporarily ended urbanization in Britain,...

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, due to economic or political reasons. I examine this...

The size distribution of cities in many countries follows some broadly regular patterns. Any good theory of city size distributions should (i) be able to account for this regularity, but also (ii) rely on a plausible economic mechanism and (iii) be consistent with other fundamental features of...

Economies at early stages of development are often shaken by abrupt changes in growth rates, whereas in advanced economies growth rates tend to be relatively stable. To explain this pattern, we propose a theory of technological diversification. Production makes use of different input varieties,...

This paper uses micro data from the 1980, 1991 and 2000 population censuses to investigate the role of changes in the industry mix in accounting for the differential trends in the incidence of child work (ages 10-15) across Brazilian states. We find that exogenous compositional changes account...

Large scale transport infrastructure investments connect both large metropolitan centers of production as well as small peripheral regions. Are the resulting trade cost reductions a force for the diffusion of industrial and total economic activity to peripheral regions, or do they reinforce the...

A rolling blackout in Colombia in the early 1990s led to a rise in unplanned births, according to research by Amar Shanghavi and colleagues. What's more, young women who became mothers after the blackout had worse outcomes in later life. The impact of power outages on fertility is an important...

This paper answers the question whether extreme power rationing can induce changes in human fertility and thus, generate "mini baby booms". We study a period of extensive power rationing in Colombia that lasted for most of 1992 and see whether this has increased births in the subsequent year,...
