We propose two indexes to measure the agglomeration forces acting within and between different regions. Unlike the existing measures of agglomeration, our model-based indexes allow for simultaneous treatment of both aspects. Local plant diffusion in a given industry is modelled as a spatial...

We propose two model-based measures of the intensity of local and global agglomeration patterns at the industry level. Spatial plant dispersion in a given industry is modeled as the outcome of an error components process that provides a convenient framework for the simultaneous treatment of...

This article investigates the geographical location of workers in jobs with high-knowledge requirements in the German economy. Our analysis takes individual-level data from the German socioeconomic panel (GSOEP) and combines them with the knowledge information for different jobs that comes from...

Worldwide trade flows are dominated by high-productivity firms, that have a large range of products. Since the product range of firms reflects partly trade flows, it is a source of economic differences in space. In this paper, I analyze the effects of the product mix of firms on agglomeration. I...

The division of labor between and within countries is driven by two fundamental forces, comparative advantage and increasing returns. We set up a simple Ricardian model with a Marshallian input sharing mechanism to study their interplay. The key insight that emerges is that the interaction...

Using a simple two-region model with the positive and negative effects of labor heterogeneity, we investigate the agglomeration pattern of entrepreneurs and the commuting pattern of heterogeneous workers. Labor heterogeneity is a source of productivity for e.g. high-tech industries as well as is...

This paper revisits a classical inquiry by addressing the question of localization and urbanization economies. We propose that specialization and diversity may offer externalities operating at different spatial scales. Using high-resolution geo-coded plant-level panel data for Swedish cities...

The last one and a half centuries have witnessed dramatic changes in the world economy. The service (tertiary) sector, which at the beginning of the 20th century was of little importance relative to agriculture and manufacturing, has become the dominant sector today, accounting for 80% and more...

The urban structures between the Member States of the European Union is very different for historical, geographical, economic reasons. However, the population is spread across geographic areas in a way that, although continuously changing, is not possible to define as random. Indeed, countries...

This paper examines the empirical relationship between agglomeration and economic growth for a panel of 48 Central and Eastern European regions from 1995 to 2006. By agglomeration, we mean the within-regional concentration of aggregate economic activity, which we measure using the 'topographic'...
