Ezra Klein on Common Mistakes by Economists

The always smart Ezra Klein has an excellent column (here) in today's Washington Post, which points out that policy proposals based simply on (presumably sound) economic theory are not necessarily worth very much, if they do not account for real-world political, ideological, cultural, and policy-implementation issues. Nothing in the column is particularly novel or surprising, but it is a nice, concise exposition of some basic problems.
