But the question is: was the bet that Greenspan made a favorable one? Whenever in the future the US finds itself in a situation like 2003, should it try to keep the economy near full employment even at some risk of a developing bubble?
从事后看，格林斯潘错了。但问题是：格林斯潘当时是否做出了一个有利的选择？在未来的任何时期， 当美国发现其又一次置身于2003年那样的境遇时，它是否应该试图保持经济的接近充分就业状态，即便这样做会冒一定的泡沫增长的风险？
