I believe in market economics. But to paraphrase Churchill - who said this about democracy and political regimes - a market economy might be the worst economic regime available, apart from the alternatives. I believe that people react to incentives, that incentives matter, and that prices reflect the way things should be allocated. But I also believe that market economies sometimes have market failures, and when these occur, there's a role for prudential - not excessive - regulation of the financial system.

In the history of modern capitalism, crises are the norm, not the exception.

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.

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.

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.

I think globalization actually maintains and fosters various elements of national and cultural identities. I don't think everything is being homogenized. If anything, your food, your culture, and your ethnicity might become part of the globalized world, and thus absorbed by other countries.

I believe, unlike people that are totally free-market, laissez-faire fundamentalists, that there is an important role that the government can play - one, in providing public goods, whether it's education, health care, or other things, and two, supervising countercyclical policy - stimulus, whether it's monetary, fiscal, or otherwise.
