Cass Sunstein and Bob Hahn write in the recent edition of The Economists' Voice that "the precautionary principle does not help individuals or nations make difficult choices in a non-arbitrary way. Taken seriously, it can be paralyzing, providing no direction at all." See the whole article here.

Also, a couple of other economists give the Clear Skies program a thumbs up with a few modifications.

Both of these articles are short, well-written, academic pieces that might make for nice handouts to classrooms or friends who could use a new perspective. If this is the approach that The Economists' Voice plans to follow, it will be something to watch.
