宏观经济名词解释：什么是凯恩斯效应 庇古效应

The Keynes effect is a term used in economics to describe a situation where a change in interest rates affects expenditure more than it affects savings.As prices fall, a given nominal amount of money will become a larger real amount. As a result the interest rate will fall and investment demanded rise.
This means that insufficient demand in the product market cannot exist forever
凯恩斯效应就是说： 利息的变化对消费的影响大于对储蓄的影响。 当价格下降 之前一定数额的钱的实际价值会升值，并造成利息的下降与投资上升。

The Pigou effect is an economics term that refers to the stimulation of output and employment caused by increasing consumption due to a rise in real balances of wealth, particularly during deflation.
庇古效应是说： 总产量与就业率的增长 是由消费增长造成的， 原因在于收支不平衡（剩余），这种现象一般会在通货紧缩时出现。

凯恩斯主义通俗理解就是通过国家的宏观调控稳定资本主义经济的一种手段。
