We compare the efficacy of vigilante justice, as represented by peer-to-peer punishment, to delegated policing, as represented by the “hired gun” mechanism, to deter free riding and improve group welfare. The “hired gun” mechanism (Andreoni and Gee, 2011) is an example of a low cost device that promotes complete compliances and minimal enforcement as the unique Nash equilibrium. We find that subjects are willing to pay to hire a delegated policing mechanism over 70% of the time, and that this mechanism increases welfare between 15% to 40%. Moreover, the lion’s share of the welfare gain comes because the hired gun crowds out vigilante peer-to-peer punishments. ER -
