The idea

What is Elasticity of demand?

Elasticity of demand measures how strongly the quantity demanded of a good responds to a change in its price, calculated as the proportional change in quantity divided by the proportional change in price. Demand is elastic when a small price rise causes a large drop in quantity, as with goods with close substitutes, and inelastic when quantity barely changes, as with salt or petrol in the short run. Elasticity determines whether raising a price increases or decreases a seller's total revenue.

Where it appears: Class 12 CBSE Economics, ISC, IGCSE and A Level Economics, IB Economics, CUET, UPSC prelims.

Where learners get stuck

Why Elasticity of demand is hard

Learners read elasticity off the slope of the curve, though a straight-line demand curve has different elasticity at every point, and they muddle the sign, the direction of the formula and the link to total revenue.

The picture a good explanation starts with: Two demand curves on the same axes, one steep and one flat, with the same price rise shown on each and the resulting change in quantity and revenue rectangles shaded.

A lesson, step by step

How a lesson on Elasticity of demand goes

    Ask

    Type or say "Why is demand for petrol inelastic?" in your own words, in any of 26 languages.

  2. 02

    Plan

    The tutor plans a storyboard, one picture per idea, starting with two demand curves on the same axes, one steep and one flat, with the same price rise shown on each and the resulting change in quantity and revenue rectangles shaded.

  3. 03

Questions learners ask about Elasticity of demand

  • Why is demand for petrol inelastic?

  • Is elasticity the same as the slope of the demand curve?

Any of these, or your own, typed or spoken. The tutor answers on the picture and adapts to how well you are following.
