I'm a rock star among geeks, wonks, and nerds.

I think it's true that the 1 Percent or the elite are living in a world of, maybe, excessive privilege, and they don't fully realize how much pain and suffering, how much anxiety exists out there.

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

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.

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.

A currency serves three functions: providing a means of payment, a unit of account and a store of value. Gold may be a store of value for wealth, but it is not a means of payment. You cannot pay for your groceries with it. Nor is it a unit of account. Prices of goods and services, and of financial assets, are not denominated in gold terms.
