Frequently asked questions
How is price elasticity of demand calculated?
Divide the percentage change in quantity demanded by the percentage change in price. A 15% fall in quantity from a 10% price rise gives an elasticity of 1.5.
What do the values mean?
Above 1 is elastic, meaning demand reacts strongly to price. Below 1 is inelastic. Demand normally moves opposite to price, so the true sign is usually negative.
