Accomplice-Witnesses, Organized Crime and Corruption: Theory and Evidence from Italy



Since 1991 the Italian Legislator grants amnesties, protection and even economic bene.ts to former mobsters cooperating with the justice. These incentives were intro- duced to break down omertà. What is the economic logic behind this policy? Did the program succeed? To address these issues we develop a model accounting for the main trade-o¤s involved in the introduction of accomplice-witnesses regulations. We argue that rewarding informants is sometimes necessary to .ght organized crime and show how the optimal amnesty varies with the e¤ectiveness of the protection program, the reliability of the informants.testimonies, the strength of external complicities, and the internal cohesion between criminal partners. The optimal policy crime, spurs prosecution and induce a negative relationship between the number of talkers and the conviction rate. The available evidence supports the model.s predictions.
