Demand Demand for a product refers to the
amount of it which will be bought per
unit of time at a particular price.
Meaning of demand Desire or want backup by money
Demand is always related to price & time.
Demand may be viewed ex –ante & ex – post.
Types of demand Consumer goods & producer goods.
Perishable & durable goods.
Autonomous & derived demand.
Price demand ,income demand & cross demand.
Individual & market demand.
Firm & industry demand.
Demand curveLaw of demand describes the general tendency of consumers behaviour in demanding commodity in relation to the changes in its price.
Law demand
the higher price of a commodity the smaller is quantity demand
SHIFTING OF DEMAND CURVE
A change in demand thus implies an increase or decrease in demand.
When more of a commodity is brought than before at any given price . There is an increase in demand.
Determinants Price.
Income.
Taste ,habits & preferences.
Substitute & complementary product.
Consumer’s expectation.
Advertisement.
Standard of living.
Age & sex ratio.
Level of taxation.
Elasticity of demand
.
Factors influencing elasticityNature commodity.
Availability of substitutes.
Number of uses.
Consumer’s income.
Height of price & change in price.
Durability of the commodity.
Proportion of expenditure.
Complementary goods.
Habit
Time.
price elasticity of demandIt is used to describe the effect of change in price on
quantity demand.
Types of price elasticity
Perfectly elastic demand.
Perfectly inelastic demand.
Relative elastic demand.
Relative inelastic demand.
Unitary elastic demand .
Perfectly elastic demand
A very small change in price leads To an infinite change in demand.
Perfectly inelastic demand
The demand for a commodity shows no response at all to a change in price , the demand remain the same it is called a perfectly inelastic demand.
Relative elastic demand
Change in the quantity demanded is greater than that of price the demand is said to be relatively elastic demand .
e > 1
Relative inelastic demand
when the proportion of change in the quantity demanded is less than that of price , the demand is considered to be relative inelastic demand.
e > 1
Unitary elastic demand
Change in demand is exactly the same as the change in the price the demand is said to be unitary elastic demand.

e = 1
Income elasticity of demand The income elasticity of demand is numerical measure of the degree to
which quantity demand responds to change in income.
Income elasticity = % change in quantity of demanded
% change in income
Negative effect Negative effect means if there is increase in income causes a decrease in quantity demand
Example
For inferior goods
(cheap whisky, artificial jewellery )
Cross elasticity of demand Cross elasticity of demand is a numerical measures of
The degree to which quantity demand of a good responds to changes in the prices of other commodities.
cross elasticity = % change in quantity demanded of good x
% change in price of good Y
CROSS ELASTICITY OF DEMAND BETWEEN TWO SUBSTITUTES
If x and y are substitutes ecwill be positive.
Example
( tea & coffee)
If the price of coffee rose ,there would be a decrease in quantity demanded of coffee and an increase in the quantity demanded of tea.
Cross elasticity of demand between two complements
If x &y are complements ec will be negative .
Example
(bread & butter)
If the price of bread rose there would be a decrease in quantity of demanded of bread and a decrease in the quantity of butter.
