Demand is the quantity of a product that consumers are willing and able to buy at each possible price over a period of time.
- 2
Why does demand require ability as well as willingness to buy?
Model answer
Wanting a product has no effect on the market unless the consumer also has the money to purchase it, so unbacked wishes are not demand.

Describe the shape and slope of a typical demand curve.
Model answer
A demand curve slopes downward from left to right, showing that a lower price is associated with a greater quantity demanded.
- 4
Explain why demand curves normally slope downwards.
Model answer
As the price falls the product becomes cheaper relative to substitutes so consumers switch to it, and the consumer's real income goes further, so more can be bought.
- 5
What is meant by a movement along the demand curve?
Model answer
A movement along the demand curve is a change in the quantity demanded caused only by a change in the product's own price.

What is meant by a shift of the demand curve?
