Questions from this subtopic
Each one with the model answer underneath.
- 1
Define price elasticity of demand.
Model answer
Price elasticity of demand measures how responsive the quantity demanded of a product is to a change in its price.
- 2
A firm's price elasticity of demand is −1.8. Explain what happens to its revenue if it raises the price.
Model answer
Demand is price elastic, so quantity falls by proportionally more than the price rises and total revenue falls.
- 3
Why is price elasticity of demand normally a negative number?
Model answer
Price and quantity demanded usually move in opposite directions, so one percentage change is positive while the other is negative.
- 4
A firm raises its price from £4.00 to £4.40 and weekly sales fall from 20,000 to 17,000 units. Calculate the price elasticity of demand.
Model answer
Price rises by 10% and quantity falls by 15%, so price elasticity of demand is −1.5.
- 5
A price elasticity of demand of −1.5 has been calculated for a product. State whether demand is elastic or inelastic and explain why.
Model answer
Demand is price elastic, because the value is greater than 1 when the sign is ignored, so quantity changes proportionately more than price.
- 6
A firm cuts its price from £20 to £18 and sales rise from 500 to 530 units. Calculate the price elasticity of demand.
Model answer
Price falls by 10% and quantity rises by 6%, so price elasticity of demand is −0.6.
