A positive income elasticity of demand is associated with normal goods; an increase in income will lead to a rise in quantity demanded. If income elasticity of demand of a commodity is less than 1, it is a necessity good. If the elasticity of demand is greater than 1, it is a luxury good or a superior good.
Income elasticity of demand is a measure used to show the responsiveness of the quantity demanded of a good or service to a change in the consumer income. Mathematically, this is calculated by dividing the percentage change in the quantity demanded by the percentage change in income. [ 16 ]
Elasticity (economics), a general term for a ratio of change. For more specific economic forms of elasticity, see: Cross elasticity of demand; Elasticity of substitution; Frisch elasticity of labor supply; Income elasticity of demand; Output elasticity; Price elasticity of demand; Price elasticity of supply; Yield elasticity of bond value
In economics, the concept of elasticity, and specifically income elasticity of demand is key to explain the concept of normal goods. Income elasticity of demand measures the magnitude of the change in demand for a good in response to a change in consumer income. the income elasticity of demand is calculated using the following formula,
A good's Engel curve reflects its income elasticity and indicates whether the good is an inferior, normal, or luxury good. Empirical Engel curves are close to linear for some goods, and highly nonlinear for others. For normal goods, the Engel curve has a positive gradient. That is, as income increases, the quantity demanded increases.
The Income elasticity of demand allows businesses to analyse and further predict the impact of business cycles on total sales. [16] The Income elastitcty of demand thus allows goods to be broadly categorised as Normal goods and Inferior goods. A positive measurement suggests that the good is a normal good, and a negative measurement suggests an ...

On the other hand, [10] the money supply curve is a horizontal line if the central bank is targeting a fixed interest rate and ignoring the value of the money supply; in this case the money supply curve is perfectly elastic. The demand for money intersects with the money supply to determine the interest rate.
