Ladbrokes Odds on Econ Nobel

How can Fama be so high on this list?

And Barro so low? To me, Barro is the obvious choice. But people say no, because he was discredited by the events of 2008-9.

Maybe. But then why is Fama up at only 5-1.

Short Fama. If betting markets were efficient, he'd be 10-1 or higher.
