My father, Benjamin Shiller, told me not to believe in authorities or celebrities - that society tends to imagine them as superhuman. It's good advice. People are snowed by celebrities all the time. In academia people have this idea of achieving stardom - publishing in the best journals, being at the best university, writing on the hot topic everyone else is writing about. But that's what my father told me not to do. He taught me that you have to pursue things that sound right to you.

There is more uncertainty than usual about job futures because computers are replacing more and more human intelligence, and globalization is proceeding at an accelerating pace.

As I write in 2012 we certainly do not believe that it is over yet, and the worst may be yet to come. Efforts by governments to solve the underlying problems responsible for the crisis have still not gotten very far, and the 'stress tests' that governments have used to encourage optimism about our financial institutions were of questionable thoroughness.

The good news is that, at least in economics, I've seen movement away from its overemphasis on mathematical models of purely rational behavior to a more eclectic and commonsense approach: research that is, among other things, more respectful of insights from psychology.

Economists who adhere to rational-expectations models of the world will never admit it, but a lot of what happens in markets is driven by pure stupidity - or, rather, inattention, misinformation about fundamentals, and an exaggerated focus on currently circulating stories.

Each profession has its own toolkit.
