If income elasticity is positive, then it is a normal good. Otherwise, it is an inferior good.

If the income elasticity of demand is negative for both goods, then they are both not inferior goods.
inferior
All Giffen goods are inferior goods. But not all inferior goods are Giffen goods. For inferior goods, the negative substitution effect will more than offset the positive income effect, so that total price effect will be negative. For Giffen goods, the positive income is positive and very strong that the law of demand does not hold. Price elasticity of Giffen good is positive. Inferior Goods: Cheap goods Giffen Goods: Rice, wheat, noodles are Giffen goods in China

income elasticity can be applied in the intersection of market demand and supply. when there is income inequality people with less income get to buy less goods than they would have wanted this affects the suppliers who will have to reduce their goods to be supplied.

Income Elasticity of Demand ( IEOD )= (% change in Quantity Demanded) / (% change in income) When IEOD > 1 then products are luxurious When 0 < IEOD < 1 then products are necessities of life When IEOD < 0 then products are inferior.

The elasticity of demand refers to how sensitive the demand for a good is to changes in other economic variables. The different types are: price elasticity, income elasticity, cross elasticity and advertisement elasticity.
When an increase in income is not associated with a change in the demand of a good.
price elasticity is the degree to which demand for a good will change relative to a change in the price of that good. Income elasticity is the degree to which demand for a good will change relative to a change in the spending power of the consumer. it is the percentage change in quantity demanded/percentage change in price.
A sticky good
Inferior goodA good for which an INCREASE(decrease) in consumer income will lead to a DECREASE(increase) in demand for that good.Normal GoodA good for which an INCREASE(decrease) in consumer income will lead to a INCREASE(decrease) in demand for that good.
