The aim, as Fed Chairman Ben Bernanke said again in December, is to “push” investors to take more risk. Specifically, it is hoped that an artificial surge in asset prices will make people feel richer and more optimistic, thus triggering “wealth effects” and “animal spirits” that stimulate consumption and investment spending, bolster job creation, and, in the process, “validate” the artificial asset pricing.
正如美联储主席本·伯南克（Ben Bernanke）12月所说，目标是“逼迫”投资者冒更大的风险。具体地说，是希望人为的资产价格飙升会让人觉得更富有更乐观，从而引发“财富效应”和“动物精神”，从而刺激消费投资支出、创造就业机会并在这个过程中使人为的资产定价“得以生效”。
