Lecture 3 - What is money? A comparative approach to measuring money Flashcards
What is money?
Anything that is generally accepted in payment for goods and services or in the repayment of debts.
What is wealth?
The total collection of pieces of property that serve to store value.
What is the difference between income and money?
Income is a flow of earnings per unit of time whereas, money is a stock; it is a certain amount at any given time.
What are the three functions of money?
Medium of exchange, unit of account, and store of value.
What does medium of exchange mean?
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.
For a commodity to function effectively as money, it has certain criteria to meet. What are these?
Be standardised (easy to determine its value), be widely accepted, be divisible (it is easy to ‘make change’), be easy to carry and not deteriorate quickly.
What is the second role of money?
To provide a unit of account that is used to measure the value in an economy. Using money as a unit of account reduces transaction costs in an economy by reducing the number of prices that need to be considered.
Money also functions as a store of value. What does this mean?
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.
Money is not unique as a store of value but why do other assets have advantages over money as a stere of value?
Other assets often pay the owner a higher interest rate than money, experience price appreciation and deliver services (e.g. house).
Money is the most liquid asset, it is the medium of exchange. How does this differ to other assets?
Other assets have to be converted into money to make purchases and transaction costs would arise.
What is liquidity?
It is the relative ease and speed with which an asset can be converted into a medium of exchange.
How good a store of value money is, depends on the…
Price level.
A doubling of all prices means that…
The value of money has dropped by half.
A halving of all prices means that…
The value of money has doubled.
What is the payments system?
The method of conducting transactions in the economy.
