Functions of Money – the easier it is to buy things the more you spend

Yap Money.jpgpewter.jpgMoney has taken various forms over the ages – whether it be tokens on a tree made of pewter (soft metal which comes from Malaysia) to the stone currency from the island of Yap in Micronesia. There was a problem with the stone currency in that one of the essential characteristics of money is portability and a 5 meter high stone with a hole in it doesn’t fit the bill let alone the wallet. Money that comes in small coins and notes became a much more efficient medium of exchange and facilitates more transactions but it still gives you a sense that you are spending it as your wallet becomes lighter and less bulky.

 

creditcardsToday the vast majority of transactions are done without cash and there is a tendency not to feel the cost of the transaction, by physically taking money out of your wallet, when paying by credit card. This ease of payment encourages us to spend more. Research has shown that credit cards make people spend 12-18% more, on average, than they would using cash. But lets go further, you  can now wave your card over the credit card terminal with no need for a security pin number or a signature. In fact a smartphone is able to carryout a similar transaction which further erodes the sense of parting with money. I recently received an updated airpoints card from a national airline which enables you to accumulate points that can be redeemed for flights. However reading the letter I was interested to see that the card was also offering me $10,000 credit limit. Credit was also offered from a petrol station and a supermarket card – the means of a deferred payment is a popular function.

For the AS level course remember the following:

The Functions of Money 

There are 4 traditional functions of money.

1. Medium of exchange. 

This is very important in a specialised economy as barter would be very inefficient. It also makes possible a great extension of the principle of specialisation.

The desirable qualities of money are as follows:-

  • Acceptable: Must be sure somebody will accept your money for goods & services
  • Scarce: Should be, if there’s too much, then no one would value it, hence gold was always good money.
  • Portable: Convenient to carry around
  • Divisible: Can be divide up into different denominations
  • Durable: Money (physical) that can last

 2. Unit of Account

A unit of account is a way of placing a specific value on economic goods and services. Thus, as a unit of account, the monetary unit is used to measure the value of goods and services relative to other goods and services. It thus enables individuals to compare, easily, the relative value of goods and services.  A firm uses money prices to calculate profits and losses: and a typical household budgets its regular expenses daily using money prices as its unit of account.

3. Store of Value. 

Once a commodity becomes universally acceptable in exchange for goods and services, it is possible to store wealth by holding a stock of this commodity. It is a great convenience to hold wealth in the form of  money. Consider the problems holding wealth in the form of wheat. It may deteriorate, it is costly to store, must be insured, and there will be significant  handling costs in accumulating and distributing it.

4. Standard of Value/Standard of Deferred Payment.

An important function of money in the modern world, where so much business is conducted on the basis of credit, is to serve as a means of deferred payment. When goods are supplied on credit, the buyer has immediate use of them but does not have to make an immediate payment. The goods can be paid for three, or perhaps six, months after delivery.
