嗨,努力学习的PZer你好:
同学你好,书上对liquidity trap的描述如下:
An unusual but important special case known as a liquidity trap occurs if a) banks are willing to hold virtually unlimited excess reserves rather than expand their balance sheets by taking deposits and making loans and/or b) demand for money balances by households and companies is insensitive to the level of income. In a liquidity trap, monetary policy will be ineffective and the AD curve will not shift despite the central bank’s efforts. Some have argued that this was a reasonable description of the US situation in 2010.
讲的是银行不愿意对外放贷,货币政策失效的情况。
而量化宽松策略是2008-2009年,央行为了解决官方利率已经接近于0,央行通过qe进一步降低利率的行为
-------------------------------就算太阳没有迎着我们而来,我们正在朝着它而去,加油!
