Global imbalances and the paradox of thrift
分析了全球失衡与金融危机的关系，指出中国等国的储蓄过剩导致全球利率下降，引发美国过度借贷用于消费和住房等非生产性投资，最终引发金融危机，并对比了凯恩斯的节俭悖论。
This paper analyses the relationship between the global imbalances and the financial crisis. The imbalances were connected with the increase in world savings emanating from the ‘savings glut’ countries, notably China. This increase in savings led to a decline in world interest rates, and thus to greater borrowing, especially in the United States. This borrowing was for financing consumption, wars, and unwise rather than fruitful investment, especially in housing. The failure to invest in fruitful investments led to the financial crisis, and thus the decline in US and world-wide aggregate demand. This was the indirect paradox of thrift. It is to be contrasted with Keynes’s paradox of thrift, where the decline in aggregate demand and output would have resulted directly from the rise in world savings. The paper also discusses why there was not more borrowing for fruitful investment, especially in developing countries, hence avoiding the financial crisis. Copyright 2013, Oxford University Press.
