It tends to be tough to get more than two economists to agree on much of anything. That doesn't seem to be the case when it comes to benefit-cost analysis. No fewer than 34 signed this Clean Water Act Brief to the Supreme Court spanning the alphabet from A for Arrow to Z for Zeckhauser:
As economists, we believe that the Second Circuit's ruling, by not
allowing the consideration of important information about the
relationships between the benefits and costs of alternatives, is
economically unsound. In particular, we believe that, as a general
principle, regulators cannot make rational decisions unless they are
allowed to compare costs and benefits and to use the results, along
with other factors as appropriate, to choose among alternatives.
To
the extent permissible under the statute and case law, EPA should be
allowed to consider benefits and costs in establishing rules for
implementing s316(b). The Court's allowing EPA to consider benefits and
costs would improve both the decision making process - by making it
more transparent - and the regulatory decisions by allowing important
relevant information to be considered explicitly.
I just wonder who will use the full suggested citation:
