The downward slope implies that the increase in income contributes to a fall in demand, and a decrease in income causes a rise in demand.

Thus, millet is an inferior good to wheat for customers. For example, the demand for millet will decrease if the income of consumers increases since they will prefer to purchase wheat instead of millet.

It refers to a condition in which demand for a commodity decreases with a rise in consumer income and increases with a fall in consumer income.

Less than unitary – If the change in the amount of a product demanded in due proportion is less than the change in consumer income in due proportion, positive income elasticity of demand will be less than unitary.

More than unitary – The positive income elasticity of demand will be more than unitary if the proportionate change in the amount of a product demanded is higher than the change in consumer income in due proportion.

Unitary – The positive income elasticity of demand will be unitary if the proportionate change in the amount of a product demanded equals the change in consumer income in due proportion.

There are three forms of positive income elasticity of demand stated as follows: The upward slope implies that the rise in income contributes to a rise in demand and vice versa. Commodities with positive income elasticity of demand are normal goods. It refers to a condition in which demand for a commodity rises with a rise in consumer income and declines with a decline in consumer income.

% Change in Income of Consumer = Change in Income of Consumer / Original Income of Consumerīased on numerical value, the income elasticity of demand is divided into three classes as follows: 1.

% Change in Demand Quantity = Change in Demand Quantity / Original Demand Quantity.

The following formula is used: Income Elasticity of Demand = % Change in Demand Quantity / % Change in Income of Consumer

The larger the income elasticity of demand for a certain product, the greater the shift in demand there is from a change in consumer income.

For a certain product, the income elasticity of demand can be positive or negative, or non-responsive.

Income elasticity of demand denotes the responsiveness to change in consumers’ income with the change in the demand for a certain good.
