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...

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 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...

Can the increasing significance of knowledge-products in national income - the growing weightless economy - influence economic development? Those technologies reduce ''distance'' between consumers and knowledge production. This paper analyzes a model embodying such a reduction. The model shows...

This paper develops a model of economic growth and activity locating endogenously on a 3- dimensional featureless global geography. The same economic forces influence simultaneously growth, convergence, and spatial agglomeration and clustering. Economic activity is not concentrated on discrete...

A fundamental issue for economists is what determines civil conflict. One unsettled question is the relative importance of political freedoms versus economic development. This paper takes a new approach to provide an answer by using micro-data based on surveys of revolutionary preferences 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,...

The Great Aid Debate pits those who are radically opposed to foreign aid against those who champion its reform to achieve greater aid effectiveness. This paper offers an analysis of this debate by introducing a heuristic distinction between aid 'radicals' and aid 'reformers'. The radical...

This paper examines the frequency, pervasiveness, and determinants of product switching by US manufacturing firms. We find that one-half of firms alter their mix of five-digit SIC products every five years, that product switching is correlated with both firm- and firm-product attributes, and...
