Another interpretation is that people are saving a great deal, and that all this money is chasing investment assets, bidding up prices. Current Fed Chairman Ben Bernanke raised this idea a few years ago, alleging a world “saving glut.”
另一种解释是人们储蓄了大量的钱，而所有这些钱正在追逐投资资产，从而哄抬了价格。现任美联储主席伯南克几年前提出了这种观点，称这是一个“储蓄过量”的世界。
