Income Elasticity

Income elasticity is an economic concept that measures the responsiveness of the quantity demanded of a good or service to a change in consumer income. It quantifies how demand shifts as income levels change, indicating whether a good is a necessity, luxury, or inferior. This metric is crucial for understanding consumer behavior and market dynamics in various economic conditions.

Also known as: Income Elasticity of Demand, YED, Income Sensitivity, Demand Elasticity to Income, Income-Responsiveness
