The income elasticity of demand measures the responsiveness of the demand with respect to changes in the consumer income. IED = (percent change quantity in demanded) / (percent change in … = (7,000-10,000) ÷ {(7,000+10,000)/2} Since cars have positive income elasticity of demand, they are normal goods (also called superior goods) while buses have negative income elasticity of demand which indicates they are inferior goods. The symbol Q 1 represents the new demand that exists when income changes to I 1. Income elasticity of demand of cars = 28.57%/50% = 0.57. Income elasticity of demand measures the degree of responsiveness of quantity of a commodity demanded to a certain change in income of buyers and is defined as the percentage change in quantity demanded divided by the corresponding percentage change in income. The income elasticity of demand can be said to be elastic when the quantity changes more than the income changes and it is inelastic when the quantity changes less than the changes in the income and its unitary elastic demand when the changes in quantity are equivalent to changes in the real income of the consumer. For example, if there is 25% increase in the income of a consumer, the demand for milk consumption would also be increased by 25%.
