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...

This paper analyses how the degree of regional integration affects regional differences in production structures and income levels. With high transport costs, industry is spead across regions to meet final consumer demad. As transport costs fall, increasing returns interacting with labour...

This paper considers the location effects of geographically discriminatory trade policy. A preferential move towards a customs union pulls industry into the integrating countries. When internal barriers fall below some critical level, input-output links between imperfectly competitive firms lead...

We develop a model in which the interaction between transport costs, increasing returns, and labour migration across sectors and regions creates a tendency for urban agglomeration. Demand from rural areas favours urban dispersion. European urbanisation took place mainly in the XIX Century, with...

This paper outlines a new approach for analysing the role of trade in promoting industrial development. It offers an explanation as to why firms are reluctant to move to economics with lower labour costs, and shows how trade liberalisation can change the incentives for firms to locate in...

European regions have experienced a polarisation of their unemployment rates between 1986 and 1996, as regions with intermediate rates have been driven by changes in regional employment, only partly offset by labour force changes. Regions'' outcomes have closely followed those of neighbouring...
