It’s On!

Freakonomics versus Marginal Revolution in a caption-that-photo contest.

Tyler Cowen has laid down the gauntlet to the Marginal Revolution readers, pointing them to our contest to caption the infamous Bush-congratulates-Krugman photo, and urging them to “see if you can beat their readers.”

I’m also excited to announce that we have a very special guest judge: Nobel Laureate Paul Krugman has agreed to pick the winning entry.

Freako readers, add your entry here; Marginal Revolters, try here.

And Tyler, I’m willing to bet on my readers; are you interested in a side bet?

Addendum: The winners are announced here.
