(1) The Percentage Method: The price elasticity of demand is measured by its coefficient E p. This coefficient E p measures the percentage change in the quantity of a commodity demanded resulting from a given percentage change in its price: Thus. Where q refers to quantity demanded, p to price and â to change. If E p p p = 1 demand is unitary elastic.
we mean a price elasticity of demand that is less than 1. Demand is elastic when the price elasticity of demand is greater than one. When the price elasticity of demand is one, we say that demand has unit elasticity.
