The Federal Reserve Act is explicit: the Fed should achieve “price stability” for the US currency, along with moderate interest rates and maximum employment. As long as inflation is somewhere between zero and 2%, the Fed should declare victory and leave it at that.
国会并未授权美联储追求这一目标。联邦储备法说的很明确：美联储应该为美国货币实现“物价稳定”，以及温和的利率和最大化的就业。只要通胀处于零和2%之间，美联储就应该认为自己是成功的，并采取放任不管的态度。
