Explanation

1
|
Consumers Equilibrium
Single
commodity
|
MUx =price
|
If MUx > Px
consumer is in gains, he will increase consumption.
MUx < Py consumer is in loss, he will reduce
consumption
|
2
|
Consumers Equilibrium
Two
commodity (utility analysis)
|
MUX/Px=
MUy/Py
|
If MUX/Px
> MUy/Py - utility per rupee from Goodx is more
than utility per rupee of Goody. So consumption of Goodx is increased and
consumption of Goody is reduced..
MUX/Px
< MUy/Py utility per rupee from
Goodx is less than utility per rupee of Goody. So consumption of Goodx is
reduced and consumption of Goody is increased.

Consumers Equilibrium
Indifference
curve approach
|
MRSxy =Px/Py
|
If MRSxy
> Px/Py - Consumer is willing to
give up more but he has to give up less amount of other good.
MRSxy < Px/Py
- Consumer is willing to give up less but he has to give up more
amount of other good.

Producers
Equilibrium
|
MC = MR
MC Must rise
after intersecting MR
|
MC > MR
adding more to cost. Profits are not maximum.
MC
|
5
|
Market
Equilibrium
|
Quantity
demanded equals to quantity supplied.
|
Qd >
Qs Excess Demand
Qd <
Qs Excess Supply
|
6
|
Equilibrium
level of income ,output and employment
|
AS = AD
C+S = C+I
|
AS > AD
unwanted unsold stock of goods. So output and employment is reduced.
AS < AD
Reduction in stock with firm. So firms will increase output by increasing
employment
|
7
|
Equilibrium
level of income ,output and employment
|
S = I
|
S > I
people are saving more and consuming less. Unwanted unsold stock of goods. So
output and employment is reduced. Income will fall and saving will fall.
S < I
people are saving less consuming more. Reduction in stock with firm. So firms
will increase output by increasing employment. Income will increase savings
will increase.
