Replication data for: Mafia in the Ballot Box

We study the impact of organized crime on electoral results, analyzing in detail the national parliamentary elections in Sicily for the period 1946-1992. We document the significant support given by the Sicilian mafia to the Christian Democratic Party when the electoral competition by the Communist Party strengthened. We also provide suggestive evidence that, in exchange for its electoral support, the mafia obtained economic advantages in the construction sector.
