OK, I said I wouldn’t give you any hints, but decided to pass one along anyway. Here are President Obama’s picks.
The President’s entry is apparently part of the same ESPN pool of which the Econbrowser Challenge is a small subset. I haven’t yet talked the President into joining the Econbrowser Group, though that’s no reason for you not to! But you only have 12 hours or so left to do so by going to the following link and filling in an entry.
And while you’re at it, you might also consider including your entry in the Environmental Economics Pool, where they even offer a prize! What’s more, last year the competition was a little softer than some of those Econbrowser sharks.
