Elastic

A demand curve on which percentage quantity changes more than percentage price is said to be elastic, or sensitive to price. If |e| > 1, demand is elastic, where e is the price elasticity of demand. If |e| = 0, demand is perfectly inelastic while if |e| is infinite, demand is perfectly elastic. If |e| 5 1, demand is unit elastic.
