The same problem haunts Bernanke’s hypothesis that slow growth reflected a “global savings glut.” From a Keynesian perspective, an increase in savings cannot explain the surge in activity that the world witnessed in the early 2000s.
伯南克的假说——慢增长反映了“全球储蓄过剩”也存在同样的问题。从凯恩斯主义角度看，储蓄的增加无法解释21世纪初世界经济活动的猛然活跃。
