但是，由于美国出口和进口分别占GDP的15%和12 % ， 出口价格下降10%将减少大约1.5%的真实（经通胀调整的）平均收入，而进口价格升高10%将让真实收入再降低1.2 % 。
But, because US exports and imports are 15% and 12% of GDP, respectively, a 10% decline in export prices would reduce average real (inflation-adjusted) income by 1.5%, while a 10% rise in import prices would reduce real incomes by an additional 1.2%.
