If the percentage change in quantity demand is equal to percentage change in income is known as income elasticity of demand equal to one. 9 27 2018 microeconomics elasticity of demand equals 1 but income decreases. Initial income is oi and quantity demand is oq. In economics the income elasticity of demand is the responsiveness of the quantity demanded for a good to a change in consumer income.
