that the price elasticity of demand is elastic. The increase of price from P to P1 caused a decrease in quantity demanded from Q1 to Q2. As denoted by the arrows‚ the change in price is smaller than the change in quantity demanded. Inelastic Demand Demand is inelastic when the percentage change in quantity demanded is less than the percentage change in price‚ i.e. when: Percentage change in the quantity demanded < 1 Percentage change in the price EXAMPLE A rise in the price of crayfish

expressed by three types of demand; inelastic demand‚ unit elastic demand‚ or relatively elastic demand. To determine the percentage of change in demand for a product or service the price elasticity equation and coefficient are used. The coefficient Ed is defined as “the percentage change in quantity demanded of product divided by the percentage change in price of product X” (McConnell‚ Brue‚ Flynn‚ 2012‚ pg. 76) The three expressions of Ed are Elastic‚ Inelastic‚ and Unit Elasticity.
