This paper seeks to analyse the extent of geographic concentration in Spanish industry. To that end the concentration index derived from a model of industrial localisation proposed in Maurel & Sédillot (1999) is used, and a comparison is made with other indices used in literature. Starting from...

This paper first reveals the basic properties behind the spatial concentration measurement when using “employment Lorenz curves”. This involves axioms adapted not only from the literature on income distribution but also from that on occupational segregation. Second, additive decompositions...

In the last few years a great number of works, involved in what has been called the New Economic Geography, have been focused on explaining the causes of agglomeration in a framework of monopolistic competition à la Dixit-Stiglitz. The purpose of this paper is to analyze, in the light of these...

This paper seeks to analyse the extent of geographic concentration in Spanish industry. To that end the concentration index derived from a model of industrial localisation proposed in Maurel & Sédillot (1999) is used, and a comparison is made with other indices used in literature. Starting from...

This paper formally shows the parallel that exists between inequality and spatial concentration measurement. This examination allows us to unveil the properties that the literature is implicitly assuming when using inequality measures to quantify the spatial concentration of economic activity....

In this paper we have developed a model that sets out to explain the existence of megacities in developing countries, in the context of a core-periphery model à la Krugman. As in Krugman and Livas Elizondo (1996), this paper also suggests that agglomeration can be fostered by manufacturers...

This paper analyses the extent of geographical concentration of Spanish industry between 1993 and 1999, and study the agglomeration economies that could underlie that concentration. The results confirm that there is major geographic concentration in a number of industries with widely varying...

<title>Abstract</title> This paper first reflects on the concentration invariance property that regional economics implicitly assumes when the locational Gini index and the generalized entropy family of concentration indexes are used. Second, it suggests that apart from these indexes, concentration measures...

By using data from the American Community Survey, this paper studies occupational segregation by ethnicity/race and gender in the US by comparing the distribution of any demographic group with the employment structure of the economy. The analysis shows that occupational segregation is...

Using the 2005–2007 American Community Survey, we analyze the occupational segregation of workers by race and ethnicity across states. Although the unconditional analysis shows great geographical variation in segregation, with the largest levels in the Southwest, the analysis of segregation...
