The winner will be announced on Monday.
Many candidates out there: Grew Mankiw's favorites are Fama, Feldstein, or Barro. Thompson Scientific's are Helpman, Grossman, Tirole, Wilson or Milgrom. Tylor Cowen would give it to Krueger, Bhagwati and Tullock.
If you have your own favorite, you can bet one dollar on him/her. A charity of your choice will get all the money collected (if you win).
Paul Krugman's grey cat has already won a Nobel, and she was not even a favorite. Will the owner do as much?
