PED

Understanding values for price elasticity of demand

• If Ped = 0 then demand is said to be perfectly inelastic. This means that demand does not change at all when the price changes – the demand curve will be vertical
• If Ped is between 0 and 1 (i.e. the percentage change in demand from A to B is smaller than the percentage change in price), then demand is inelastic. Producers know that the change in demand will be proportionately smaller than the percentage change in price
• If Ped = 1 (i.e. the percentage change in demand is exactly the same as the percentage change in price), then demand is said to unit elastic. A 15% rise in price would lead to a 15% contraction in demand leaving total spending by…
