This paper reflects about the invariance property that regional economics is implicitly assuming when “relative” inequality measures, such as the Gini index, are used to quantify the geographic concentration of economic activity. In addition, it proposes a new concentration measure that is...

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...

The aim of this paper is twofold. First, it shows the properties that regional economics is implicitly assuming when “relative” inequality measures, such as the Gini coefficient and the generalized entropy family of indexes, are used to quantify the geographic concentration of economic...

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....

This paper first proposes a measure, the mutual information index derived from the information theory, to quantify overall concentration from an axiomatic perspective. The analysis reveals that this overall concentration measure can be written as the weighed sum of the Theil index for each...
