1. Lars P. Hanse and/or Hal White. Econometrics has not been awarded in a while and the current economic conditions would suggest rewarding more theoretical economists.
2. Richard Thaler and/or Robert Schiller. These seem to be the favorites.
3. Paul Romer. Macroeconomics has not been awarded recently but given the short-run macroeconomy, they probably won't give it to most of the macroeconomist. Romer is of course known for growth theory, so I think they might go in this direction.
4. Gordon Tullock. Most people think he missed his chance, so I'm just being contrarian with this choice.
