Elasticity is the ratio of the % change in quantity to the % change in price. So if the two are identical, than it is said to be unitary elastic. If quantity changes more than price, then it is said to be elastic. If the quantity changes less than price, then it is said to be inelastic.
In general, the demand for a good is said to be inelastic (or relatively inelastic) when the PED is less than one (in absolute value): that is, changes in price have a relatively small effect on the quantity of the good demanded. When the price elasticity of demand for a good is perfectly elastic (E d is â â), any increase in the price, no matter how small, will cause demand for the good to drop to zero. 2  Hence, when the price is raised, the total revenue falls to zero.
