Price elasticity of demand
REVISION: Prelim Paper 2, p. 11. Notes already distinguish elastic from inelastic
demand
___________________________________________________________________________
Case Study: @DBE November 2024
The graphs below show the response to the change in quantity demanded
in relation to price in a market.
Factors that may lead to price elasticity of demand:
• Nature of the product
• Availability of substitute products
• Consumer's budget/income
• Time period
Indicate the type of elasticity illustrated in:
(a) Graph A = Price elastic
(b) Graph B = Price inelastic
Give a reason for the answer to
Graph A as a price elastic
illustration.
= The change in price results in a
huge change in quantity
demanded.
