Robert Shiller was surprised when he got the call telling him he'd won the Nobel Memorial Prize in economics — surprised that he'd won (of course), but also surprised that he was sharing the award with Eugene Fama.
"He and I seem to have very different views," Shiller told me. "It's like we're different religions."
In particular, they have very different views about economic bubbles.
"The word 'bubble' drives me nuts, frankly," Fama told me.
Fama believes markets are basically rational. At any given moment, he says, prices reflect the collective wisdom of everyone in the market.
