Common Mistakes by Economists

Tyler Cowen has assembled two lists of common mistakes made by economists. The first is of common mistakes made by right-wing/market-oriented economists and the second is of common mistakes made by left-wing economists. They’re both quite interesting.

UPDATE: I’m not endorsing every item on each list, but I think they both provide much to consider and ample grist for discussion.

SECOND UPDATE: Ezra Klein comments.
