还有一些经济学家会说，如果美联储承诺将年通胀目标定在高于2%的水平，或承诺实现这一目标需要多少量化宽松就实施多少量化宽松就好了，这样货币动作就足够了。
Still others would make the case that monetary action would have been enough, if only the Fed had committed to a target for annual inflation that was higher than 2% and vowed to do as much quantitative easing as necessary to reach that goal.
