The WSJ offers up some predictions, although not for economics.
For this year (NB: I've never been right in the past) I am predicting a joint prize for Oliver Williamson and Jean Tirole. Williamson is by some accounts the most cited living economist, Tirole is European, the pick would not look "political," and yet agency problems have proven to be pretty important as of late. The selection would look relevant. I used to pick Fama each year but the time is no longer right for him, whether that is fair or not (I would say not).
My dark horse pick is a joint prize to environmental economists, including William Nordhaus for the concept of "green accounting."
I thank Akshay for the pointer. What do you all predict?
