From The Economist cover story: Danger time for America

In [Greenspan's] final days of glory, it may therefore seem churlish to question his record. However, Mr Greenspan's departure could well mark a high point for America's economy, with a period of sluggish growth ahead. This is not so much because he is leaving, but because of what he is leaving behind: the biggest economic imbalances in American history ...

Handovers to a new Fed chairman are always tricky moments. They have often been followed by some sort of financial turmoil, such as the 1987 stockmarket crash, only two months after Mr Greenspan took over. This handover takes place with the economy in an unusually vulnerable state, thanks to its imbalances. ...

How should Mr Bernanke respond to falling house prices and a sharp economic slowdown when they come? While he is even more opposed than Mr Greenspan to the idea of restraining asset-price bubbles, he seems just as keen to slash interest rates when bubbles burst to prevent a downturn. He is likely to continue the current asymmetric policy of never raising interest rates to curb rising asset prices, but always cutting rates after prices fall. This is dangerous as it encourages excessive risk taking and allows the imbalances to grow ever larger, making the eventual correction even worse. If the imbalances are to unwind, America needs to accept a period in which domestic demand grows more slowly than output.
