Exceptions to the Law

Of Demand
Law Of Demand :
The law of demand states that, other
things remaining the same, the quantity
demanded of a commodity is inversely related
to its price.
If a price of a commodity falls, the
quantity demanded of it will rise, and if the
price of the commodity rises, its quantity
demanded will decline.
Assumptions under which law of
demand is valid
 No change in price of related commodities.
 No change in income of the consumer.
 No change in taste and preferences,
customs, habit and fashion of the consumer.
 No change in size of population
 No expectation regarding future change in
price.
Exceptions to the law of demand

Inferior goods/ Giffen goods


A Giffen good is a good for which demand increases as the price
increases and falls when the price decreases.

Some special varieties of inferior goods are termed as giffen goods.


Cheaper varieties of goods like low priced rice, low priced bread, etc
are some examples of Giffen goods.
Goods having prestige value

 Few goods like diamond can be purchased only by rich people.


The prices of these goods are so high that they are beyond the
capacity of common people. The higher the price of the
diamond the higher the prestige value of it.
 In this case, a consumer will buy less of the diamonds at a low
price because with the fall in price, its prestige value goes
down. On the other hand, when price of diamonds increase,
the prestige value goes up and therefore, the quantity
demanded of it will increase.
Price expectation

 When the consumer expects that the price of the


commodity is going to fall in the near future, they
do not buy more even if the price is lower.
 On the other hand, when they expect further rise
in price of the commodity, they will buy more even
if the price is higher. Both of these conditions are
against the law of demand.
Fear of shortage

 When people feel that a commodity is going to


be scarce in the near future, they buy more of it
even if there is a current rise in price.
 For example: If the people feel that there will be
shortage of L.P.G. gas in the near future, they
will buy more of it, even if the price is high.
Change in income

 The demand for goods and services is also affected


by change in income of the consumers.
 If the consumers’ income increases, they will
demand more goods or services even at a higher
price. On the other hand, they will demand less
quantity of goods or services even at lower price if
there is decrease in their income. It is against the
law of demand.
Change in fashion

 The law of demand is not applicable when the


goods are considered to be out of fashion.
 If the commodity goes out of fashion, people do
not buy more even if the price falls. For
example: People do not purchase old fashioned
shirts and pants nowadays even though they've
become cheap. Similarly, people buy
fashionable goods in spite of price rise.
Basic necessities of life

 In case of basic necessities of life such as


salt, rice, medicine, etc. the law of
demand is not applicable as the demand
for such necessary goods does not change
with the rise or fall in price.
