I realize that this is another of those dog-bites-man stories, but Greg Mankiw would have easily won his proposed bet
with Paul Krugman about the effectiveness of Obamanomics. This is, if the former had had the guts to take the offer. Krugman had actually called Mankiw's prediction "evil". I guess it's a classic conundrum: Would you rather be evil but be almost always right, or be self-described as non-evil but be wrong about pretty much everything.
