The recent period has been marked by a transformation to an economy that is more productive as competitive forces become increasingly intense and new technologies raise the efficiency of our businesses...While these tendencies were no doubt in train in the "old," pre-1990s economy, they accelerated over the past decade as a number of technologies with their roots in the cumulative innovations of the past half-century began to yield dramatic economic returns.

These days, even out of office, I still read economic reports.

I don't think it's possible for the Fed to end its easy-money policies in a trouble-free manner. Recent episodes in which Fed officials hinted at a shift toward higher interest rates have unleashed significant volatility in markets, so there is no reason to suspect that the actual process of boosting rates would be any different. I think that real pressure is going to occur not by the initiation by the Federal Reserve, but by the markets themselves.

The very nature of finance is that it cannot be profitable unless it is significantly leveraged... and as long as there is debt, there can be failure and contagion.

Productivity is notoriously difficult to predict.

Fear and euphoria are dominant forces, and fear is many multiples the size of euphoria. Bubbles go up very slowly as euphoria builds. Then fear hits, and it comes down very sharply. When I started to look at that, I was sort of intellectually shocked. Contagion is the critical phenomenon which causes the thing to fall apart.

If we allow terrorism to undermine our freedom of action, we could reverse at least part of the palpable gains achieved by postwar globalization. It is incumbent upon us not to allow that to happen.
