Watch it animateQuiz yourself on Price Elasticity of Demand & Supply

Step by step

  1. 1

    Start with ordinary demand.

  2. 2

    Now imagine the good is a necessity, insulin, petrol for commuters. Buyers barely respond to price: demand steepens.

  3. 3

    Any supply disruption now moves PRICE dramatically and quantity barely at all.

Where this shows up

Examiners ask this as: inelastic demand, necessity, addictive, steep demand.
