What is income elasticity of demand with diagram?
In the given figure, quantity demanded and consumer’s income is measured along X-axis and Y-axis respectively. When the consumer’s income rises from OY to OY1 the quantity demanded of inferior goods falls from OQ to OQ1 and vice versa. Thus, the demand curve DD shows negative income elasticity of demand.
