The Effects of Mafia Infiltration on Public Procurement Performance

We examine the effects of Mafia infiltration on public procurement performance, based on a sample of 68,063 public work contracts (PWC) awarded by Italian municipalities over the period 2012–2017, of which 687 are identified as Mafia-infiltrated, either because of being awarded by municipal councils subsequently dissolved due to Mafia infiltration, or because of being won by Mafia-owned firms.
