This working paper offers a synthesis of the current knowledge on the determinants of productivity. It carefully reviews both “spatial” (e.g. agglomerations, infrastructure, geography) and “aspatial” (e.g. human capital, labour regulations, industry-level innovation and dynamism)...

This paper estimates agglomeration benefits across five OECD countries, and represents the first empirical analysis that combines evidence on agglomeration benefits and the productivity impact of metropolitan governance structures, while taking into account the potential sorting of individuals...

OECD countries and their regions are ageing fast. In principle, the negative impact of ageing on the growth rate of per capita gross domestic product could be offset by increases in productivity. However, for many regions, productivity growth required to maintain per capita GDP levels constant...

This paper estimates agglomeration benefits based on city productivity differentials across five OECD countries (Germany, Mexico, Spain, United Kingdom, and United States). It highlights the relationship between cities’ governmental fragmentation and productivity, and represents the first...

We document and then develop a model explaining and relating changes in firms' organisation and in urban structure. Sharing of business services by headquarters and of sector-specific intermediates by production plants within a city reduces costs, while congestion increases with city size. A...

To identify communication externalities in French cities, we exploit a unique survey recording workplace communication of individual workers. Our hypothesis is that in larger and/or more educated cities, workers should communicate more. In turn, more communication should have a positive effect...

This paper develops a quantitative model of city structure to separate agglomeration forces, dispersion forces and fundamentals as determinants of location choices. The model remains tractable and amenable to empirical analysis because of stochastic shocks to worker productivity, which yield a...

CEO incentive contracts are commonplace in China but their incidence varies significantly across Chinese cities. We show that city and provincial policy experiments help explain this variance. We examine the role of two policy experiments: the use of Special Economic Zones (SEZs) to attract...

Henry Overman surveys the evidence on potentially effective responses to the recession and longer-term structural change.

Spatial inequality in developing countries is due to the natural advantages of some regions relative to others and to the presence of agglomeration forces, leading to clustering of activity. This paper reviews and develops some simple models that capture these first and second nature economic...
