Quote Of The Day

“Early empirical analysis by Isaac Ehrlich found a substantial incremental deterrent effect of capital punishment, a finding that coincides with the common sense of the situation: it is exceedingly rare for a defendant who has a choice to prefer being executed to being imprisoned for life. Ehrlich’s work was criticized by some economists, but more recent work by economists Hashem Dezhbakhsh, Paul Rubin, and Joanna Shepherd provides strong support for Ehrlich’s thesis; these authors found, in a careful econometric analysis, that one execution deters 18 murders. Although this ratio may seem implausible given that the probability of being executed for committing a murder is less than 1 percent (most executions are in southern states–50 of the 59 in 2004–which that year had a total of almost 7,000 murders), the probability is misleading because only a subset of murderers are eligible for execution. Moreover, even a 1 percent or one-half of 1 percent probability of death is hardly trivial; most people would pay a substantial amount of money to eliminate such a probability”. –Richard Posner, discussing capital punishment and the execution of Stanley “Tookie” Williams
