My main interest, however, was in economics, not law.

Of course. I favor passive investing for most investors, because markets are amazingly successful devices for incorporating information into stock prices.

My research interests since then have shifted strongly towards the economic and regulatory problems of the financial services industry, and especially of the securities and options exchanges.

I should mention that I am a member of the board of directors of Dimensional Fund Advisors.

My movies don't make any money, and they don't really light the world on fire. But I'm really lucky because I've gotten them made.

I don't think any of us can do much about the rapid growth of new technology. A new technology helps to fuel the economy, and any discussion of slowing its growth has to take account of economic consequences. However, it is possible for us to learn how to control our own uses of technology.

There are a lot of parallels between being a mutual fund manager and being a general manager. Both in the financial markets and in baseball, we're dealing with a world where uncertainty reigns. We're trying to predict the future performance of human beings. It's a fundamental difficulty for which we both have to account.

We're fighters. We go out there, and we'll open a window of opportunity, and they're only open for so long, and we have to take advantage of that time right then. When I did it, I was 30-31 years old. Maybe it was a little too late that I should have did it, but I did it right. I was okay with the money that I got, the money that I made.
