As a humanitarian and economic 'bad', infliction of punishment require
s justification in terms of compensating achievements, as well as mora
l appropriateness. In the context of road accidents, there is evidence
that increasing the certainty and swiftness of threatened punishment
may deter risky behavior, although increasing the severity of the thre
at seems ineffective. These effects may be generalizable to other kind
s of accidents, but empirical evidence is lacking. A further possibili
ty for the justifiable use of punishment is in its application to negl
igent service of alcohol.
