Similarly, it is asked, is a normal good elastic or inelastic?
A normal good, also called a necessary good, doesn't refer to the quality of the good but rather, the level of demand for the good in relation to wage increases or declines. A normal good has an elastic relationship between income and demand for the good.
One may also ask, why is income elasticity of demand important? Knowledge of income elasticity of demand helps firms predict the effect of an economic cycle on sales. Luxury products with high income elasticity see greater sales volatility over the business cycle than necessities where demand from consumers is less sensitive to changes in the cycle.
Similarly, it is asked, what is an income elastic good?
Income elasticity of demand refers to the sensitivity of the quantity demanded for a certain good to a change in real income of consumers who buy this good, keeping all other things constant. With income elasticity of demand, you can tell if a particular good represents a necessity or a luxury.
How can we tell if a good is normal or inferior by calculating its income elasticity of demand?
A normal good has a positive sign, while an inferior good has a negative sign. For example, if a person experiences a 20% increase in income, the quantity demanded for a good increased by 20%, then the income elasticity of demand would be 20%/20% = 1. This would make it a normal good.
