We investigate urban GDP per capita growth across the EU12 using data for functionally defined cities—rather than administrative regions. We test hypotheses on the role of human capital, EU integration and fragmentation of urban government and explore spatial dependence and mechanisms of...

We investigate urban GDP pc growth across the EU12 using data for functionally definedcities - rather than administrative regions. We test hypotheses on the role of human capital,EU integration and fragmentation of urban government and explore spatial dependence andmechanisms of spatial...

This paper investigates growth differences in the urban system of the EU12 over the last decades of the 20th Century. Models in which growth of real GDP p.c. and rates of population growth are the dependent variables are compared. This suggests that it makes sense to model GDP growth in a...

This paper investigates differences in the rate of growth of population across the large city-regions of the EU12 between 1980 and 2000. The US model which assumes perfect factor mobility does not seem well adapted to European conditions. There is evidence strongly suggesting that equilibrating...

Why are some cities specialised and others diversified? What are the advantages and disadvantages of urban specialisation and diversity? To what extent does the structure of cities, and the activities of the firms and people in them, change over time? How does the sectoral composition of cities...

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...

London is one of the world’s major cities, and one of its most diverse. London’s cultural diversity is widely seen as a social asset, but there is little hard evidence on its importance for the city’s businesses. Theory and evidence suggest various links between urban cultural diversity...

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...
