Q

What does medium of exchange mean?

A

It is used to pay for goods and services. It promotes economic efficiency by minimising the time spent in exchanging goods and services (transaction costs). In the barter economy, transaction costs are high because people have to satisfy a ‘double coincidence of wants’. If money is introduced, it allows people to specialise in what they do best and encourages the division of labour.

Q

What is the second role of money?

Q

Money also functions as a store of value. What does this mean?

A

It is a repository of purchasing power over time. A store of value is used to save purchasing power from the time income is received until the time it is spent. This function is useful, because most of us do not want to spend our income immediately upon receiving it, but rather prefer to wait until we have the time or the desire to shop.

Q

What is commodity money?

A

Money made up of precious metals or another valuable commodity. From ancient times until several hundred years ago, commodity money functioned as the medium of exchange in all but the most primitive societies.

17
Q

Examples of commodity money.

A

Gold, silver, shells, cattle, peppercorns, tobacco. These goods with an ‘intrinsic value’ - a direct use. Their value was directly observable as they could be used for something valuable.

18
Q

What was the problem with commodity money?

A

The form of money is very heavy and hard to transport from one place to another (gold and silver). Peppercorns were perishable, cattle were not easily divisible and shells could easily break.

19
Q

What is fiat money?

A

Paper currency decreed by governments as legal tender (meaning that legally it must be accepted as payment for debts) but not convertible into coins or precious metal.

20
Q

Advantages of paper currency.

A

Paper currency has the advantage of being much lighter than coins or precious metal, but it can be accepted as a medium of exchange only if there is some trust in the authorities who issue it and if printing has reached a sufficiently advanced stage that counterfeiting is extremely difficult. Countries can change the currency that they use at will as paper currency has evolved into a legal arrangement.

21
Q

Disadvantages of paper currency.

A

They are easily stolen and can be expensive to transport in large amounts because of their bulk.

22
Q

What are cheques?

A

Instructions from the customer to the bank to transfer money from their account to someone else’s account when they deposit a cheque. They allow transactions to take place without the need to carry around large amounts of currency.

23
Q

Advantages of cheques.

A

Improves economic efficiency and reduces transaction costs. They can be written for any amount up to the balance in the account, making transactions for large amounts much easier. Loss from theft is also greatly reduced, and because they provide convenient receipts for purchases.

24
Q

Disadvantages of cheques.

A

It takes time to get cheques from one place to another, a particularly serious problem if you are paying someone in a different location who needs to be paid quickly. Also, it usually take several business days before a bank will allow you to make sue of the funds from a cheque you have deposited. If your need for cash is urgent, this feature of paying by cheque can be frustrating. Furthermore, all the paper shuffling required to process cheques is costly.

25
Q

How do electronic payments benefit us?

A

It has now become cheap and really quick to transfer funds and pay bills electronically.

26
Q

What is electronic money?

A

Money that exists only in electronic form. Examples include debit cards and smart cards. Smart cards are stored value cards that contain a computer chip that allows it to be loaded with digital cash from the owner’s bank account whenever needed. They can be loaded with digital cash from ATMs. A third form of electronic money is e-cash.

27
Q

What are Bitcoins?

A

A digital currency not issued by a Central Bank that can be exchanged directly among users, with transactions being verified and recorded on a public register.

28
Q

How good is Bitcoin as a use of money?

A

They are accepted as a medium of exchange although not universally. They are not subject to inflation, as their quantity is limited and known in advance. Their decentralised and anonymous nature can be exploited for illegal purposes.

29
Q

What are monetary aggregates?

A

Variations among measure of money supply. Generally ranges from narrow to broad definitions. They do not usually move together.

30
Q

What affects the measurement of monetary aggregates?

A

Differences in what members of society accept as a means of exchange (e.g. Mexico with pesos and US dollars). Moreover, some assets are accepted as money in some societies by not others (e.g. in those countries where banks are not sufficiently widespread to attract household savings, most of the money supply would be in cash). The institutions responsible for issuing monetary aggregates differ from country to country (in US the Federal Reserve Bank issues money and in the Euro area the European Central Bank issues money and in the UK the Bank of England issues money) . Definition of monetary aggregate changes over time as people’s habits change.

31
Q

What is M1?

A

Consists of currency in circulation as well as demand deposits and other chequeable deposits held in depository institutions. Definition tends to be pretty similar across central banks.

32
Q

33
Q

What is M3?

A

Includes repurchase agreements. Only some central banks calculate it. The definition varies widely across countries.

34
Q

How do central banks resort to boosting GDP growth?

A

Expanding the money supply, albeit with the understanding that this is apt to result in inflation.
