I am quite international. My background, born in Turkey. My family is a Jewish family from Iran, so I went from Turkey to Iran to Israel, and then grew up in Italy and ended up in U.S. for graduate school. So I tend to look at things from an international perspective, and I think that gives you a little bit of a broader view of what's going on.

If we didn't have greed, market economies wouldn't be as innovative as they are. But in my view, greed has to be contained by the fear of losses, so there has to be a system where, if you take too much risk, you go into bankruptcy. You don't systematically bail out people who take excessive risks.

I'm not a pessimist by nature. I'm not someone who sees things in a bleak way.

The gains from technology must be channeled to a broader base of the population than has benefited so far.

I believe investors should invest for the long run, so I don't buy and sell. I usually maintain the classic index of global equities, diversified U.S. and global and emerging markets, and when the risk is larger, I diminish the amount in global equities and put more into liquid assets - but very irregularly.

But in the financial markets, without proper institutional rules, there's the law of the jungle - because there's greed! There's nothing wrong with greed, per se. It's not that people are more greedy now than they were 20 years ago. But greed has to be tempered, first, by fear of losses. So if you bail people out, there's less fear. And second, b prudential regulation and supervision to avoid certain excesses.

In an extreme credit crunch, leveraged purchases of gold cause forced sales, because any price correction triggers margin calls. As a result, gold can be very volatile - upward and downward - at the peak of a crisis.
