Understanding Money (Cambridge (CIE) O Level Economics)

Revision Note

The Meaning of Money

  • Prior to the creation of money, individuals and firms had to accept other goods or services as payment, or be self-sufficient by producing everything required

  • Often lacking self-sufficiency or driven by the desire for a wider range of goods/services, bartering became the norm but it too had problems

  • As individuals and firms trade with each other in order to acquire goods or raw materials, they require a means of exchange that is acceptable and easy to use 

  • Modern currency fulfils this purpose and money functions as a medium of exchange, a measure of value, a store of value, and a method of deferred payment

The Functions of Money

The Four Functions of Money

A Medium of Exchange

A Measure of Value

 A Store of Value

A Method of Deferred Payment

  • Without money, it becomes necessary for buyers and sellers to barter (exchange goods)

  • Bartering is problematic as it requires two people to want each other's goods (double co-incidence of wants)

  • Money easily facilitates the exchange of goods as no double co-incidence of wants is necessary

  • Money provides a means of ascribing value to different goods and services

  • Knowing the price of a good in terms of money allows both consumers and producers to make decisions in their best interests

  • Without this measure it is difficult for buyers and sellers to arrange an agreeable exchange

  • Money holds its value over time (of course inflation means that is not always true!)

  • This means that money can be saved

  • It remains valuable in exchange over long periods of time

  • Money is an acceptable way to arrange terms of credit (loans) and to settle any future debts

  • This allows producers and consumers to acquire goods in the present and pay for them in the future

The Characteristics of Money

  • Many items were used for centuries as a form of money such as gold, silver, shells, beer, tobacco

  • However, each one of these items had some characteristics that made the less than ideal for exchange in certain circumstances

  • Good money has a number of essential characteristics - and modern currency fulfils them all

The six characteristics of good money
  1. Divisibility: to be a valued medium of exchange, currency must be divisible. €50 notes can be exchanged for €10 euro notes or €1 coins

  2. Acceptability: the currency must be valued and widely accepted by society as a valid way to pay for goods/services

  3. Durability: the currency must be robust, not easily defaced/destroyed and last for a long period of time

  4. Scarcity: the supply of the currency should be such that remains desirable and retains its value in the market. Oversupply would decrease its worth

  5. Uniformity: in order to be a valid measure of value each denomination must be exactly the same e.g. every $50 note must be exactly the same

  6. Portability: good currency is easy to carry/conceal
