Pathways of Innovation: The I-District Effect Revisited
The I-district effect establishes the existence of dynamic efficiency in Marshallian industrial districts in the form of a positive innovative differential comparing to the average of the economy. The hypothesis has been empirically validated for the case of technological innovation using patent indicators. Empirical research has assumed that all types of patentable figures (utility models, national patents, EPO, WIPO) have the same weight regardless of its actual or expected market value, which may be questionable given the differences in coverage, protection and cost of each figure. In this article, we question the existence of the I-district effect when each patent is weighted by its exp…
