【十分钟读懂系列】之格雷欣法则

这个帖子基本上是对“格雷欣法则”盲目扩展的糟糕例子。引用下文，厘清“Gresham's law”：

Gresham's law, named after Sir Thomas Gresham, who was a financial agent of the English Crown in the 16th century, states that overvalued money drives undervalued money out of circulation: "bad money drives out good" for short.

More accurately, the law should state something along the lines of "government-enforced parities that alter the market value of money have the effect that overvalued money drives out undervalued money."

Because in a free market those products and goods that are of higher value stick around longer than low-quality products, Gresham's law only applies when government monetary intervention is present.

400多年前，英国经济学家格雷欣发现了一有趣现象，两种实际价值不同而名义价值相同的货币同时流通时，实际价值较高的货币，即良币，必然退出流通——它们被收藏、熔化或被输出国外；实际价值较低的货币，即劣币，则充斥市场。人们称之为格雷欣法则，亦称之为劣币驱逐良币规律。
