Income Elasticity And Inferior Goods

An inferior good has a negative income elasticity of demand.

Income elasticity and inferior goods. Examples could be second hand clothes rice potatoes etc. A normal good has positive and an inferior good has negative elasticity of demand. These are goods whose demand decreases when the consumers income increases. Normal necessities have a positive but low income elasticity compared to luxurious goods.

Yed inferior goods are characterised by low quality and are goods with better alternatives. Those goods whose demand decreases with an increase in consumer s income beyond a certain level is called inferior goods. The word inferior in this case does not mean substandard goods. As consumers income rises they buy fewer inferior goods.

When the income elasticity of demand is negative the good is called an inferior good. Again how much it shifts depends on how large the negative income elasticity is. On the other hand income elasticity is negative i e. For example if average incomes rise 10 and demand for holidays in blackpool falls 2.

When income rises people can afford to forego the cheap alternative and buy the higher quality good instead. A holiday in blackpool is an inferior good. For an inferior good that is when the income elasticity of demand is negative a higher level of income would cause the demand curve for that good to shift to the left. Conversely there is an.

The yed of blackpool holidays is 0 2. If the quantity demanded of a product increases with increase in consumer income the product is a normal good and if the quantity demanded decreases with increase in income it is an inferior good. It relates to the affordability of such goods. A typical example of such type of product is margarine which is much cheaper.

The income elasticity coefficient or yed for normal necessities is between 0 and 1. Their demand falls with the availability of quality alternatives. In the case of normal goods there is a direct relationship between income changes and demand curve. Your disposal income is limited which you must spend after.

Income elasticity of demand for normal goods is positive but less than one.
