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...

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...

This paper assesses the agglomeration pattern of four-digit industries in Germany using a rich data set on the population of German firms. To identify geographical agglomeration, we follow the distance based approach of Duranton and Overman (2005) and find that the location pattern of 78% of our...

This paper examines the 522 most important composers in the last 800 years, as identified by Murray (2003), in terms of their birth location and migration. It also looks at detailed patterns of migration and tendencies to cluster in certain cities for those composers born from 1750 to 1899. This...

The paper Investigates stability and change of regional economic activities in the long-run. As the unit of analysis we selected the machine tool industry in West Germany for the years 1953 to 2002. We spot a strong variance in the activities between the different regions. These differences are...

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....
