Dating from the seminal work of Ellison and Glaeser [11] in 1997, a wealth of evidence for the ubiquity of industrial agglomerations has been published. However, most of these results are based on analyses of single (scalar) indices of agglomeration. Hence it is not surprising that industries...

The standard approach to studying industrial agglomeration is to construct summary measures of the “degree of agglomeration” within each industry and to test for significant agglomeration with respect to some appropriate reference measure. But such summary measures often fail to distinguish...

This paper presents an application of a recently developed approach by Matteson and James (2012) for the analysis of change points in a data set, namely major financial market indices converted to financial return series. The general problem concerns the inference of a change in the distribution...

The standard approaches to studying industrial agglomeration have been in terms of summary measures of the “degree of agglomeration” within each industry. But such measures often fail to distinguish between industries that exhibit substantially different spatial scales of agglomeration. In a...
