How MUCH?
Robert D. Cooter*
Abstract: An economic model of deterrence is used to derive
two prescriptions for punitive damages that apply to economi-
cally motivated defendants, including businesses. To recover
punitive damages, a plaintiff should have to prove a gross
shortfall from the legal standard by the defendant that would be
profitable if liability were limited to compensatory damages. In a
word, incentive inadequacy should be proven. A key element in
the proof is establishing the existence and extent of enforcement
error. If the court finds that punitive damages are to be awarded,
the punitive multiple should be set equal to the reciprocal of the
enforcement error. These rules, if adopted, would provide incen-
tives for efficient deterrence  and   would  have significant
consequences for current legal practice, including making the ra-
tio rule more definite, lowering the ratios actually allowed, and
largely eliminating a defendant's net worth as a consideration for
setting punitive damages.
