我的想法


金钱的职能主要有三个 Money can fulfill 3 functions:

  1. Medium of exchange
  2. Unit of account
  3. Store of Value

其中如何理解 Medium of exchange 呢?

Money makes it unnecessary for “double coincidence of wants”

Becomes a barter economy ( 以物换物 )

For example,

A sells wheat and buys potatoes

B sells oranges buys wheat

C buys oranges sells potatoes

他们三个可以使用钱来充当统一的中间媒介

There is no “Double Coincidence of wants”
