INCOMEELASTICITY OF
DEMAND
Definition
Other things remaining the same, it
is degree of responsiveness of
quantity demanded of a commodity
due to change in consumer’s income
In other words
Income Elasticity of Demand measures
by how much the quantity demanded
changes with respect to the change in
income.
Mathematical Expression
Where,
EY = Elasticity of demand
q = Original quantity demanded
∆q = Change in quantity demanded
y = Original consumer’s income
∆y = Change in consumer’s income
Practical Example
Suppose that the initial income of a person is
Rs.2000 and quantity demanded for the
commodity by him is 20 units.
When his income increases to Rs.3000,
quantity demanded by him also increases to
40 units.
Find out the income elasticity of demand.
Solution
Here, q = 100 units
∆q = (40-20) units = 20 units
y = Rs.2000
∆y = Rs. (3000-2000) =Rs.1000
Hence, an increase of Rs.1000 in
income i.e. 1% in income leads to
a rise of 2% in quantity
demanded.
Types of Income Elasticity of demand
1. Positive income elasticity of demand
(EY>0)
– Income elasticity greater then unity (EY > 1)
– Income elasticity equal to unity (EY = 1)
– Income elasticity less then unity (EY < 1)
2. Negative income elasticity of demand
( EY<0)
3. Zero income elasticity of demand ( EY=0)
1. Positive income elasticity of demand
(EY>0)
If the quantity demanded for a commodity
increases with the rise in income of the
consumer and vice versa, it is said to be
positive income elasticity of demand.
For example:
As the income of consumer increases, they
consume more of superior (luxurious) goods.
Income elasticity greater then unity
(EY > 1)
Percentage change in
quantity demanded for a
commodity is greater
than percentage change
in income of the
consumer, it is said to be
income greater than
unity
Income elasticity equal to unity
(EY = 1)
Percentage change in
quantity demanded for a
commodity is equal to
percentage change in
income of the consumer
Income elasticity less then unity
(EY < 1)
Percentage change in
quantity demanded for a
commodity is less than
percentage change in
income of the consumer
2. Negative income elasticity of
demand ( EY<0)
Quantity demanded for a
commodity decreases
with the rise in income of
the consumer and vice
versa
3. Zero income elasticity of demand
( EY=0)
Quantity demanded for a
commodity remains
constant with any rise or
fall in income of the
consumer
