The determinants of industry concentration : two new empirical regularities
MetadataShow full item record
This paper reports two new empirical regularities relating to industry concentration. First, concentration levels closely correlate in related industries. Second, the correlation is moderated by the degree of relatedness between the industries. These regularities are derived from the Trinet database, using a survivor-based measure of relatedness. We argue that these previously overlooked relations may be explained in terms of 1) “spillover effects” between industries and 2) lifecycle factors.
