Over the past three decades much empirical work has appeared on the effect of the criminal law on crime rates. Usefully summarized in review articles by, among others, Professors Daniel Nagin of Carnegie Mellon University and Michael Tonry of the University of Minnesota (click here and here for examples), this research offers several insights for those engaged in the fight against corruption.
The first is that the criminal justice system can make a difference. Save for acts committed in the heat of the moment, crime is a cost-benefit proposition. Would-be criminals tote up the (usually) monetary gains of violating the law against the risks of being caught and punished and, when the benefits exceed the costs, commit an offense. Thus policies that drive up the cost of crime by increasing the chances an offender will be caught, prosecuted, and appropriately punished reduce the crime rate. Recent studies confirm that corruption crimes are no exception. Putting more resources into to prosecuting corruption in the United States and ensuring corruption in the construction of roads is detected both reduced corruption.
But if the good news from the deterrence literature is that the criminal law can make a difference, the bad news is that that the difference is not easy to realize and that the logic of deterrence can lead policymakers astray. One of the more striking findings is that what would seem to be the easiest way to enhance deterrence, sharp increases in the penalties for corruption crimes, may actually lead to more corruption.
