New knowledge generated by an economic agent in a region will tend over time to flow to other economic agents in the same region but also to economic agents in other regions. It is quite common in the literature to use the concept of knowledge spillovers for such knowledge flows, irrespective of...

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...

This Paper proposes a two-region model of endogenous growth, which is a natural combination of a core-periphery model a la Krugman and of a model of endogenous growth a la Grossman/Helpman/Romer. Specifically, we add to the core-periphery model an R&D sector that uses skilled labour to create...

This paper is concerned with methods for analysing spatial data. After initial discussion on the nature of spatial data, including the concept of randomness, we focus most of our attention on linear regression models that involve interactions between agents across space. The introduction of...

The direct impact of local public goods on welfare is relatively easy to measure from land rents. However, the indirect effects on home and job location, on land use, and on agglomeration benefits are hard to pin down. We develop a spatial general equilibrium model for the valuation of these...

We investigate the impact of within-country spatial concentration of economic activity on country-level growth, using cross-section OLS and dynamic panel GMM estimation. Agglomeration is measured alternatively through measures of urbanization and through indices of spatial concentration based on...

This Paper links the performance of new technology firms, measured in terms of growth, to geographic location. We introduce a model of firm growth that is specific to characteristics of the location as well as the firm and industry. The model is estimated using a new dataset identifying the...

Large media clusters have emerged in a limited number of large cities, characterizing the geographical concentration of the global media industry. This paper starts by exploring the effect of the rapid advancement of Information and Communication Technologies (ICT) had on the media economy. It...

This paper studies how firm heterogeneity in terms of productivity affects the balance between agglomeration and dispersion forces in the presence of pecuniary externalities through a selection model of monopolistic competition with endogenous markups. It shows that firm heterogeneity matters....
