Interpretation of Income Elasticity of Demand Depending on the values of the income elasticity of demand, goods can be broadly categorized as inferior goods and normal goods. Normal goods have a positive income elasticity of demand; as incomes rise, more goods are demanded at each price level.
Normal goods whose income elasticity of demand is between zero and one are typically referred to as necessity goods, which are products and services that consumers will buy regardless of changes in their income levels. Examples of necessity goods and services include tobacco products, haircuts, water and electricity.
As income rises, the proportion of total consumer expenditures on necessity goods typically declines. A typical example of such type of product is margarine, which is much cheaper than butter.
Luxury goods represent normal goods associated with income elasticities of demand greater than one. Consumers will buy proportionately more of a particular good compared to a percentage change in their income. Consumer discretionary products such as premium cars, boats and jewelry represent luxury products that tend to be very sensitive to changes in consumer income.
When a business cycle turns downward, demand for consumer discretionary goods tends to drop as workers become unemployed.
But a positive income elasticity of demand is linked with normal goods. In this case, a rise in income will lead to a rise in demand. Types of Income Elasticity of Demand There are five types of income elasticity of demand: A rise in income comes with bigger increases in the quantity demanded.
