以下是引用cityustd在2008-2-11 12:58:00的发言:Is credit card a form of money?
許多同學跟我說不是
他們的原因是信用於不是Unit of Account
所以不是,這個理由是耳光了
我剛才看了Paul的宏觀經濟學
他的解釋截然不同
他說因為money is any asset can easily convertable to other goods to deal with transaction.
Credit card is not an asset, rather, it is liability. Thus, credit card is not a money,
這個解釋我喜歡
what is asset? what is liability?
An asset is something that can be used to generate income, and has its own value.
A liability is a loan must be paid with its interest (if any).
It is debatable whether it will be regarded as a form of money, Currently, economically, it is not a form of money, because credit card can not be used so wide as money itself.
