The income elasticity of demand being greater than one, the commodity ...
Explanation:
Income elasticity of demand refers to the responsiveness of quantity demanded to a change in income of consumers. If the income elasticity of demand for a commodity is greater than one, it is known as a luxury good.

Luxury goods are those goods whose consumption increases with an increase in consumer income. For example, a luxury car, high-end smartphones, designer clothing, expensive jewelry, etc. People tend to buy more of these goods when their income increases and less when their income decreases.

On the other hand, if the income elasticity of demand for a commodity is less than one, it is known as a necessity good. Necessity goods are those goods whose consumption remains the same even when consumer income changes. For example, food, water, shelter, basic clothing, etc. People tend to buy the same amount of these goods regardless of their income level.

Conclusion:
In conclusion, the income elasticity of demand being greater than one indicates that the commodity is a luxury good. This means that as consumer income increases, the demand for the commodity increases at a higher rate.
