What is price elasticity of demand? Explain the types of price elasticity of demand.
The Price Elasticity of Demand refers to the degree of responsiveness of
demand to the change in the price of the commodity.
Types of price Elasticity of Demand:
The following are the main types of price elasticity of
demand:
1. Relatively
Elastic Demand:
Relatively elastic demand refers to the demand when the
proportionate change produced in demand is greater than the proportionate
change in price of a product. The numerical value of relatively elastic demand
ranges between one to infinity.
2. Relatively
Inelastic Demand:
Relatively inelastic demand is one when the percentage
change produced in demand is less than the percentage change in the price of a
product. The numerical value of relatively
elastic demand ranges between zero to one (ep<1).
3. Unitary
Elastic Demand:
When the proportionate change in
demand produces the same change in the price of the product, the demand is
referred as unitary elastic demand. The numerical value for unitary elastic
demand is equal to one (ep=1).
4. Perfectly
Elastic Demand:
When a small change in price of a
product causes a major change in its demand, it is said to be perfectly elastic
demand. In perfectly elastic demand, a small rise in price results in fall in
demand to zero, while a small fall in price causes increase in demand to
infinity. In such a case, the demand is perfectly elastic or ep =
00.
5. Perfectly
Inelastic Demand:
A perfectly inelastic demand is
one when there is no change produced in the demand of a product with change in
its price. The numerical value for perfectly inelastic demand is zero (ep=0).
