Ben Bernanke, the US Federal Reserve chairman, once famously pinned the whole US current account deficit on a “global savings glut.” But it would be more accurate to say that there is global investment shortfall, with investment trending downwards despite the upward trend in global growth.
当然，孤掌难鸣。为了让美国经济在世界上带赤字运行，其它国家必须愿意提供能自动抵销的等量储蓄。美联储主席Ben Bernanke的一句名言曾将美国全部的经常账目赤字归罪于“全球性的储蓄过剩”。但更为准确的说法是全球投资不足，虽然全球经济增长趋向放慢，但投资却趋向提升。
