It's actually a tribute to the quality of economics teaching that they have persuaded so many generations of students to believe in so much that seems so counter to what the world is like. Many of the things that I'm going to describe make so much more common sense than these notions that seem counter to what one's eyes see every day.

I think what they've been doing is largely almost in firefighting mode without a good conceptual framework - either at the micro or the macro level. Micro, you would ask: "What kind of financial or banking system do we want?" Macro, you would say: "What are the underlying problems in the structure of our economy?"

The extra curricular activity in which I was most engaged - debating - helped shape my interests in public policy.

The IMF is a more complicated issue. I think there is a broad sentiment among both the left and the right that the IMF may be doing more harm than good. On the right, there's the view that it represents a form of corporate welfare that is counter to the IMF's own ideology of markets. But anybody who has watched government from the inside recognizes that governments need institutions, need ways to respond to crises. If the IMF weren't there, it would probably be reinvented. So the issue is fundamentally reform.

I trace the inequality to a particular set of decisions that we took when we lowered the tax rate from 91% down to very low levels at the top, where we stripped away regulations. So the result of that was not a more dynamic economy, but a more unequal society. We tried the experiment of trickle-down. A third of a century later, we can say fairly definitively that it was a failure.

The important lesson of the deficit is - and the national debt - is we have to be careful about how we're spending money.

The fact that the government had to put up hundreds of billions of dollars to Citibank in guarantees was a public declaration that Citibank was a mess. Making Citibank go through financial restructuring would not have conveyed any more different information. So it's very hard to see why it would have had that kind of a panic if it were done well.
