Cost-benefit default principles

Courts should be reluctant to apply the literal terms of a statute to mandate pointless expenditures of effort.... Unless Congress has been extraordinarily rigid, there is likely a basis for an implication of de minimis authority to provide exemption when the burdens of regulation yield a gain of trivial or no value.(1) It seems bizarre that a statute intended to improve human health would... lock the agency into looking at only one half of a substance's health effects in determining the maximum level for that (2) substance. [I]t is only where there is "clear congressional intent to preclude consideration of cost" that we find agencies barred from considering Costs.(3) In order better to achieve regulatory goals - for example, to allocate resources so that they save more lives or produce a cleaner environment - regulators must often take account of all of a proposed regulation's adverse effects, at least where those effects clearly threaten serious and disproportionate public harm. Hence, I believe that, other things being equal, we should read silences or ambiguities in the language of regulatory statutes as permitting, not forbidding, this type of rational regulation.(4) The rule-implicit valuation of a life is high - about $4 million - but not so astronomical, certainly by regulatory standards, as to call the rationality of the rule seriously into question, especially when we consider that neither Hepatitis B nor AIDS is a disease of old people. These diseases are no respecters of youth; they cut off people in their working years, and thus in their prime, and it is natural to set a high value on the lost years.(5).
