It is calculated as the ratio of the percentage change in quantity demanded to the percentage change in income. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp manish1008 Bahadurgarh, India 1k Questions 1k Answers 0 Best Answers 4k Points View Profile manish1008 Added an answer on May 7, 2020 at 6:10 am Types of Income Elasticity of demand are as such: Positive income elasticity of demand Negative income elasticity of demand Zero income elasticity of demand 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Ayush Moradabad, India 126 Questions 703 Answers 0 Best Answers 962 Points View Profile Ayush Added an answer on May 7, 2020 at 12:36 am 5 types of income elasticity of demand are as follows. 1. 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. 2. 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). 3. 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. Mathematically, relatively elastic demand is known as more than unit elastic demand (ep>1). For example, if the price of a product increases by 20% and the demand of the product decreases by 25%, then the demand would be relatively elastic. 4. 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. For example, if the price of a product increases by 30% and the demand for the product decreases only by 10%, then the demand would be called relatively inelastic. The numerical value of relatively elastic demand ranges between zero to one (ep<1). Marshall has termed relatively inelastic demand as elasticity being less than unity. 5. 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). 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Featured image Select file Browse Save my name, email, and website in this browser for the next time I comment.
