Questions from this subtopic
Each one with the model answer underneath.
- 1
Define demand.
Model answer
Demand is the quantity of a good or service that consumers are willing and able to buy at a given price over a given period.
- 2
Define supply.
Model answer
Supply is the quantity of a good or service that producers are willing and able to offer for sale at a given price over a given period.
- 3
Why does the demand curve for a product slope downwards?
Model answer
As price falls the product becomes affordable to more consumers and better value than its substitutes, so the quantity demanded rises.
- 4
Why does the supply curve for a product slope upwards?
Model answer
A higher price makes each unit more profitable, which persuades existing firms to produce more despite rising costs and attracts additional producers into the market.
- 5
Distinguish between a movement along a demand curve and a shift of the whole curve.
Model answer
A movement along the curve is caused only by a change in the price of the good itself, whereas a shift of the whole curve is caused by a change in any other determinant of demand.
- 6
State four determinants of demand other than the price of the good itself.
Model answer
Consumer incomes, the prices of substitutes and complements, tastes and advertising, and the size and structure of the population.
