Is There a New Economy?
美联储主席格林斯潘在1998年的一次演讲中，承认经济出现了未预料到的新特征，同时阐述了旧经济中关于预期影响投资和市场的持久教训。
Federal Reserve Chairman Alan Greenspan inaugurated the Haas Annual Business Faculty Research Dialogue at the University of California, Berkeley, on September 4, 1998. In this article, the chief architect of U.S. monetary policy acknowledges the unpredicted and somewhat inexplicable new features of the economy. He also lays out some enduring lessons from the old economy. One of those lessons is that expectations about the future inevitably hold sway in the markets for both financial capital and physical capital. Investment inherently turns on expectations about the sizes and risks of profit and loss. These expectations reflect not only data but also human psychology.
