I want Carmen Reinhart and Ken Rogoff to win. See their book "This time is different, Eight Centuries of Financial Folly"
Their work helping us understand international financial crises is very important to policy makers and the lay people alike. Their work can be applied, their work can be understood and explained to most people. Their work should be discussed by politicians in this election.
It would be cool to see Steven Levitt (Freakonomics) win
I would be happy with Stephen Ross or Robert Shiller. One them probably will.
