La loggia P2 e il mondo finanziario italiano. Alcune evidenze empiriche basate sulla social network analysis

We investigate the rule that the P2, the well-known Italian clandestine masonic lodge, had in the economic developments in the country. Considering all firms listed on the Milan Stock Exchange, we analyse the interlocking directorates between the banks and firms infiltrated and not infiltrated by the P2. Our results show that in the 1980-1981 period firms infiltrated by the P2 accounted for the most part of the connections and exhibited higher network centrality. Since 1982 there is a general scaling-down of these firms: an event consistent with negative impact of the public discovery of the P2 lodge during 1981.
