5. Reducing unemployment has no effect on the production potential of the
economy. It is because production potential is determined assuming full em-
ployment. It simply helps in reacting potential.

or
Price of inputs forms a major part of the cost of production for producing a
commodity. Rise in price of inputs increase the cost of production and re-
duces the profit margin. It a result supply falls.
7. Budget set is the set of all possible combinations of the two goods which a
consumer can afford given his income and prices in the market.
Whereas budget line is a graphical representation of all possible combina-
tions of two goods which can be purchased with given income and prices of
the goods, when consumer spend his entire income.
8. Law of variable proportions : Law of variable proportions states that as we
increase quantity of only one input keeping other inputs constant total product
initially increases at an increasing rate, then at decreasing rate and finally fall.
It does not operate in the long run because in the long run output can be changed
by changing all factors of production.
9. Perfect competition is that market situation in which large number of buyers
and large number of sellers buy & sell homogeneous product at a given price,
that is determined by the industry.
Features of perfect competition :
1. Homogeneous product

and large number of sellers buy & sell homogeneous product at a given price,

Features of perfect competition :
1. Homogeneous product
www.tiwariacademy.com
www.tiwariacademy.com
2. Perfect knowledge
3. No control over price
4. Demand  curve is perfectly elastic
whereas monopolistic competition is that market situation in which there
are large number of sellers which sell differentiated products.
Features of monopolistic competition :
1. Differentiated product
2. Lack of perfect knowledge
3. Partial control over price
4. Demand curve downward sloping and elastic
or
In oligopoly market situation price tends to stay fixed irrespective of changes
in demand and supply conditions firms use other methods like advertising
better service, after sale service etc to compete with one another.
10. Condition’s for consumer’s equilibrium
(1) MRS = 
x
y
P
P
(2) MRS continuously falls
When price of y good falls then condition will MRS < 
x
y
P
P
 it means that to
obtain one more unit of x the consumer is willing to sacrifice less units of y as
compared to what is required in the market. It induces the consumer to buy
less of x and more y.
As a result, MRS rises till it becomes equal to the ratio of prices and the equi-
librium is established.
or
Expansion in demand : When the quantity demanded rises due to a decrease
in the price, keeping other factors constant. For example rise in demand of
mobile set when its price decreases.
Increase in demand : A rise in the demand of a commodity caused due to any
factor other than the commodity caused due to any factor other then the com-
prise of the commodity. Example increase in demand of car, when its price is
same, because of rise in income of consumer.
