The spatial distribution of industries and population is quite lumpy, and this lumpiness varies across industries. Nevertheless, we show using Japanese data for metropolitan areas that the locations of both industries and population are linked by surprisingly simple and persistent patterns. In...

The spatial intensities of both industries and population are highly uneven across space. Moreover, these intensities differ not only across industries, but also change through time. Nevertheless, we show using Japanese data for metropolitan areas in two time periods that the location...

In this paper, we propose a statistical index of industrial localization based on Kullback-Leibler divergence. This index is particularly well suited to cases where industrial data is only available at the regional level. Unlike existing regional-level indices, our index can be employed to test...
