Elasticity of demand is an important variation on the concept of demand. Demand can be classified as elastic, inelastic or unitary.
An elastic demand is one in which the change in quantity demanded due to a change in price is large. An inelastic demand is one in which the change in quantity demanded due to a change in price is small.
The formula for computing elasticity of demand is:
(Q1 – Q2) / (Q1 + Q2)
(P1 – P2) / (P1 + P2)
If the formula creates an absolute value greater than 1, the demand is elastic. In other words, quantity changes faster than price. If the value is less than 1, demand is inelastic. In other words, quantity changes slower than price. If the number is equal to 1, elasticity of demand is unitary. In other words, quantity changes at the same rate as price.
