The Fed could argue that the gap between current and full-employment GDP is larger than the 6.1% unemployment rate implies, owing to the large number of part-time workers who would prefer full-time employment and the sharp decline in the labor force participation rate. If the GDP gap is 4%, as a recent Congressional Budget Office estimate implied, the Taylor rule would indicate an optimal federal funds rate of about 1.25% (2 + 1.5 – 0.25 – 2), compared to the current rate of only 0.1%.
考虑到充分就业的GDP水平的不确定性，这条规则仍给美联储保留了自由裁量权。美联储可能认为，当前和充分就业时期GDP比6.1%的失业率所暗示的差异还要大，因为大量的兼职工人宁愿全职就业以及劳动力参与率大幅下滑。如果正如最近国会预算办公室估计的那样，GDP的差距是4%，那么泰勒规则表明的最佳联邦基金利率约为1.25%（2 + 1.5 - 0.25 – 2），而目前的速度仅为0.1%。
