At a time when inflation is already close to 2% or higher, depending on how it is measured, the real federal funds rate would be at zero at the end of 2015. Instead of ensuring price stability, monetary policy would be feeding a further increase in the inflation rate.
据我判断，这样的利率太低了。通胀已经接近甚至超出2%（取决于不同的度量方法），因此2015年底实际联邦基金利率将为零。货币政策将无法确保价格稳定，反而会导致通胀率的进一步上升。
