Recent research has found that the multiplier for discretionary fiscal policy – the change in output caused by a change in discretionary government spending – is larger when nominal interest rates are low and there is a significant amount of underutilized resources. These conditions describe the US economy as it faces yet another round of government spending cuts that would have negative multiplier effects on GDP and job growth.
最新的研究发现，自由裁量财政政策乘数——即自由裁量政府支出变化引起的产出变化——在名义利率较低、大量资源未获得充分利用时较高。这些情况表明，美国经济所面临的新一轮政府支出削减将对GDP和就业增长产生负乘数效应。
