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...

Hundreds of studies have failed to establish the effects of decentralisation on a number of important policy goals. This paper examines the cases of Bolivia and Colombia to explore decentralisation’s effects on government responsiveness and poverty-orientation. I first summarize economic data...

I examine decentralization through the lens of the local dynamics that it unleashes. The national effects of decentralization are simply the sum of its local-level effects. Hence to understand decentralization we must first understand how local government works. This paper proposes a theory of...

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,...

Rapid urbanisation is a major feature of developing countries. Some 2 billion more people are likely to become city residents in the next 30 years, yet urbanisation has received little attention in the modern development economics literature. This paper reviews theoretical and empirical work on...

Hundreds of studies have failed to establish the effects of decentralization on a number of important policy goals. This paper examines the remarkable case of Bolivia to explore decentralization's effects on government responsiveness and poverty-orientation. I first summarize econometric results...

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...
