Silberman uses econometric methods to measure the effectiveness in terms of criminal deterrence of two factors: the degree of punishment; and the probability of apprehension. A simple "expected loss" model would predict that deterrent effect would depend only on the result of multiplying the penalty by the probability of it occurring. Silberman concluded that contrary to this model, the likelihood of punishment had a greater effect in most situations.
Silberman also states, "Crime does more than expose the weakness in social relationships; it undermines the social order itself, by destroying the assumptions on which it is based."
