Rounding Error and Information Quality:
The case of Exxon Shipping Co. v. Baker
by Richard Belzer
in Information Quality
Last week the Supreme Court reversed an appellate court opinion that would have imposed $2.5 billion in punitive damages resulting from the 1989 Exxon Valdez oil spill. In the majority opinion written by Justice David Souter, the Court opined on a matter of maritime law for which there was neither a constitutional precedent nor operating law. The Court ruled that a 1:1 ratio of punitive to compensatory damages "is a fair upper limit in such maritime cases."
The Court obtained this ratio by conducting an ad hoc qualitative statistical analysis of trial court practice, which yielded a ratio of 0.65:1, then rounding up to 1:1. It is instructive to note the practical financial significance of the arcane information quality issue of significant figures (see here and here). More...

Applying it to gasoline
by Richard Belzer
in Legislation, Regulatory Economics
Energy economist Jonathan Lesser publishes a commentary in the Wall Street Journal "recommending" a cap-and-trade program for gasoline.

Economists, Advocacy Groups, and Climate Change:
The Southern Alliance for Clean Energy's 'Economist Statement'
by Richard Belzer
in Regulatory Economics
The Senate is this week debating what would be the most far-reaching environmental legislation in US history, the Lieberman-Warner Climate Security Act (S. 3036). A regional US advocacy group, the Southern Alliance for Clean Energy (SACE), has distributed a "Cap and Trade Economist Statement" which would imply that economists favor the bill.
The Statement is interesting on several levels. First, it never mentions the bill being debated. Second, it focuses solely on one narrow (but politically important) aspect -- whether carbon emission permits would be given way or auctioned. Third, the principles that SACE wants economists to agree with are fundamentally incompatible with elementary economics. Finally, SACE says that a number of distinguished economists have signed the Statement anyway. More...
