In this paper we propose an adjustment to the Herfindahl–Hirschman concentration index for
explicitly considering the role of the topology of financial economic networks on market
concentration. The case study of the Italian stock market serves for outlining the relevance of
the shareholding network in the measurement of effective concentration. Moreover, we
deepen the analysis of the network comparing network centrality measures, that are a well
known method for understanding the relative relevance of network nodes. The correlations …
