It is fine to decry corruption. But just as with AIDS, we must also work at other levels. A second level is that of reducing risks. By definition corruption is immoral. But corruption is also a crime of calculation.
Individuals weigh the benefits and the costs of giving and taking bribes.
These costs include moral costs, and the weighing takes place in individual consciences that are shaped by social values and cultural norms. But because economic calculations are present, corruption will respond to changes in the benefits that can be gained from the illegal transaction, which in turn depend on the way the system of supplying those benefits is structured. Corruption will also respond to the costs of the illegal transaction, which in turn depend on the risks of being discovered and prosecuted, and the penalties that result from prosecution. In short, quite apart from an analysis of morals or attitudes, we can analyze systems in terms of their vulnerability to corruption. Competition is less vulnerable to corruption than monopoly.
