A note on ..............Demand for money

Demand for money balance is liquidity preference.
Whether to hold cash or put it in savings bank so as to earn interest.
People desire to hold money balance from   two motives —
1. The Transaction Motive
2. The Speculative Motive

Transaction motive
Holding money for transactions
Transaction demand for money in an economy,  Mt  can be written as
 v.Mt  = T 
Where,  v is velocity of circulation of money
             T is the total value of transaction in the economy.

Velocity
the rate at which money circulates
definition:  the number of times the average rupee changes hands in a given time period
example:  In 2010,
Rs.500 crores in transactions
money supply = Rs.100 crores
The average Rupee is used in five transactions in 2010
So, velocity = 5

speculative motive
Demand for money for speculation is speculative motive.
Speculative demand for money can be written as

Mͩs =  rmax -  r/ rmin - r               r = market rate of interest
                                               
As r decreases from r max to r min, the value of Mͩs  increases from 0 to infinite.

Liquidity trap
It’s a situation where the speculative money demand function is infinitely elastic.
                                      

Thus,   Demand for Money  =  Transaction demand for money +   Speculative demand for     money
A note on..........NATIONAL INCOME & RELATED AGGREGATES 

GNP & GDP

GNP=GDP+NFIA        (NFIA is Net Factor Income from Abroad=factor income received from abroad -fact income paid abroad)

GDP=GNP-NFIA
GNP &GDP are calculated at Market Price (MP)& Factor Cost (FC)

The difference between MP&FC is Net Indirect Tax (NIT) i.e.,
MP = FC + NIT
FC = MP – NIT                             (NIT is added to MP & deducted in FC)
NIT = Indirect Tax - Subsidies
Tax on goods & services are Indirect Tax.           Subsidies are provided by the Govt.
                        
Therefore,

GNPmp = GDPmp + NFIA
GDPmp = GNPmp – NFIA          OR        GNPmp = GNPfc + NIT         GDPmp = GDPfc + NIT
           
GDPfc = GNPfc – NFIA
GNPfc = GDPfc + NFIA
                  OR
GDPfc = GDPmp – NIT
GNPfc = GNPmp - NIT

NNP & NDP

NNP = GNP – D                   (D=depreciation)
NDP = GDP – D
NNPfc = NNPmp – NIT

NNPfc is the National Income
                                             NNPmp = NNPfc + NIT

PERSONAL INCOME
The part of National Income received by households is PI
PI = NI – Undistributed profits – Net interest payment made by households – Corporate tax + Transfer payments.
A part of profit not distributed among factors of production is UP.
Tax on the profit of firms is Corporate tax.

TRANSFER PAYMENTS
Unilateral payments without any quid-pro quo.
(quid-pro-quo means “expecting anything in return”)
For example – Pensions, scholarships, etc.
TPs are Current Transfer & Capital Transfer.
Current Transfer are the transfer for current consumption. e.g., pensions, scholarships, etc.
Capital Transfer are the transfer for Capital formation. e.g., financial assistance for infrastructure

PERSONAL DISPOSABLE INCOME
PDI = PI – Personal Taxes – Non-Tax payments.
NATIONAL DISPOSABLE INCOME
NDI = NNPmp + Other Current transfers from the rest of the world
NDI gives an idea of the maximum amount of goods & services the domestic economy has at its disposal.


Gifts & aids are example for Current transfers from the rest of the world.



A note on ........INCOME DETERMINATION

1.      What is MPC (marginal propensity to consume) ? How is it related to  MPS(marginal propensity to save)?

MPC refers to ratio of change in consumption to change in income.

MPC=ΔC/ΔY

Relationship between MPC & MPS
1.MPC + MPS = 1
2.MPC = 1 – MPS
3.MPS = 1 – MPC

2. Difference between Ex-ante & Ex-post investment 
         
Ex-ante investment
Ex-post investment

planned
Actual
Hypothetical or assumed
real
Planned on the basis of future expectations
Result of various economic activities

3. what is effective demand ? How will you determine the autonomous expenditure multiplier when price of goods and rate of interest are given ?

If the elasticity of supply is infinite, then the output will be solely determined by aggregate demand at this price in the economy. This is called Effective Demand.

      The equilibrium level of output and aggregate demand is derived by solving the equation,

      Y = AD,          Y = A + cY                                         A is autonomous expenditure
      Y – cY = A,    Y( 1 – c ) = A                                      c is MPC
      Y = A / 1 – c
      The value of Y depends on the parameters A and C.

4.                  Match the column B and C with A
A
B
C
APC
ΔC / ΔY
1-APC
APS
C / Y
1-MPC
MPC
S /Y
1-APS
MPS
ΔS / ΔY
1-MPS

  1. Paradox of Thrift
If all the people of the economy increase the proportion of income they save ( i.e, if the MPS of the economy increases) the total value of savings in the economy will not increase – it will either decline or remain unchanged. This result is known as Paradox of Thrift. (draw diagram)

* AGGREGATE DEMAND (AD)
            The total demand of goods and services in the economy at a particular price level id AD.
AD consists of Consumption, Investment and Government spending. i.e.,
AD = C+I+G                          C=Ĉ+cY         I = Ī                 Ā=Ĉ+Ī                       
Or        AD = Ā + cY
* AGGREGATE SUPPLY
            AS is the total supply of goods and services in the economy at a particular price level.



 A note on......    Money & Banking



Barter system -   Exchange of goods for goods & Services for services.


Defects of Barter system
1.Double coincidence of wants –need to have mutually exchangeable goods.
2.Indivisibility of commodities
3.Lack of common measure of value
4.Lack of proper store of value.


Money:  definition    

Money is the stock  of assets that can be readily used to make transactions.

Primary functions-     1.Medium of exchange -we use it to buy stuff
2.Measure of value – goods & services

Secondary functions- 1.Standard of deferred payment – future payment
2.Store of value 
3.Transfer of value- transfers purchasing power from the present to the future

CONTINGENT FUNCTION1.Basis of credit           2.Distribution of National Income

3.Medium of compensation   4.Liquidity– money is the most liquid of all assets


Classification of money
1.Legal tender money – money which has legal sanction

2.Full bodied money (standard money) – face value is equal to its intrinsic value (value of metal)

3.Fiat money – legal tender money having no intrinsic value. e.g. currency notes and coins

Indian Monetary System
Meaning – the monetary standard and monetary set up of a country.
The type of standard money used in the country is its monetary standard .
The apex monetary authority of our country is RBI.

The system of currency issue
The system of note issue in India is The Minimum Reserve System( MRS)
RBI issues currency notes above Rupee 1.


RESERVE BANK OF INDIA ( RBI ) -    
RBI is the Central Bank of our country

FUNCTIONS OF RBI

1. Note issue – RBI issues currency notes & coins
2. Banker, Agent & Adviser to the Govt.
3. Custodian of foreign exchange reserves
4. Bankers’ Bank – RBI controls & regulates the commercial banks through its Monetary Policy
5.Lender of the last resort – RBI helps the commercial banks in times of crisis.
6.Controller of credit & money supply – through its Monetary Policy RBI controls the volume of credit.
7. Publisher of reports – periodical reports on banking & other monetary matters.
           

  Commercial Banks
Accept deposits from the public
Lending money
Borrowing rate – the rate of interest             offered by the bank to deposit holders
Lending rate – the rate of interest levied      for lending money
The difference between lending & borrowing rate is called “spread”,  and is the profit appropriated by the banks.

Deposits -         1. savings deposits / demand deposits— chequeable deposits having low   interest rate.
2. Time deposits / fixed deposits / term deposits—  Have a fixed period to maturity        
Having high interest rate

Money Supply
Legal definitions of Money - Money Supply is a stock variable.

Money Supply is the total stock of money in circulation at a particular point of time.


Measures of Money Supply by RBI


1.  M1= CU + DD                  CU is currency held by the public.
                                                DD is demand deposits held by the commercial banks.       
2.  M2= M1 + Savings deposits with Post Office savings    bank
3.  M3= M1 + Net time deposits of Commercial Banks
4.  M4= M3 + Total deposits with Post Office savings organizations


Narrow & Broad Money  -   M1 and M2 are known as Narrow Money
M3 and M4 are known as Broad Money
M1 is the most liquid asset
M4 is the least liquid asset


AGGREGATE MONETARY RESOURCE (AMR)
            
M3 is the most commonly used measure of money supply and it is the AMR.

MONEY CREATION BY THE BANKING SYSTEM
1. The Currency Deposit Ratio (cdr)
                          cdr =CU/DD
                         it reflects people’s preference for liquidity.
2. The Reserve Deposit Ratio (rdr)
                          rdr = R/DD
It is the proportion of the total deposits commercial banks keep as reserves.
Rdr has two instruments

1. Cash Reserve Ratio (CRR) –  The fraction of commercial banks deposits kept in RBI is CRR.
2. Statutory Liquidity Ratio (SLR) – Commercial banks have to keep a given fraction of their total deposits n the form of specified liquid assets.

BANK RATE
To control the value of rdr  RBI uses another instrument called Bank Rate,
It is the rate at which RBI lend money to the commercial banks.
A high BR makes borrowing costly for commercial banks.

HIGH POWERED MONEY (H)
The total liability of the Monetary authority of the country, RBI, is called the H or Monetary Base.
H = CU + R                    R is the reserves

Demand for money
Demand for money balance is liquidity preference.
Whether to hold cash or put it in savings bank so as to earn interest.
People desire to hold money balance from   two motives —
1. The Transaction Motive
2. The Speculative Motive
Transaction motive
Holding money for transactions
Transaction demand for money in an economy,
MT  can be written as
v.M  = T 
Where,  v is velocity of circulation of money
                                   T is the total value of transaction in the economy.
Velocity
basic concept:  the rate at which money circulates
definition:  the number of times the average rupee changes hands in a given time period
example:  In 2010,
Rs.500 crores in transactions
money supply = Rs.100 crores
The average Rupee is used in five transactions in 2010

So, velocity = 5.
