Urban economists hypothesize that industrial diversity matters for urban growth and development, but metrics for empirically testing this relationship are limited to simple concentration metrics (e.g. location quotient) or summary diversity indices (e.g. Gini, Herfindahl). As shown by recent...

This paper provides a nuance picture of the mechanisms through which temporary and permanent spatial co-location simultaneously sustain firm's innovation. Using a large sample of footwear clustered firms, results suggest that, on the one hand, intra-cluster Vertical relationships contribute to...

In this paper, we evaluate the spatial location patterns of Spanish manufacturing firms and we assess the different tendencies to cluster in each industry relative to the whole of manufacturing.
