Question 12.
Explain Demand-pull and Cost push inflation.
Answer:
Demand-Pull Inflation:
At all points of time in the Economy, the demand and supply play an important role.
Eg: Where the is more demand and supply is less, the price of the product increases.

Cost-Push Inflation:
When the cost of the raw material and the input increases, this inflation occur. Increase in wages paid to the labour also leads to Inflation.

Question 13.
State Cambridge equations of value of money.
Answer:
(Cash Balance Approach)
The Marshall Equation is M = KPY
M – Quality of money
Y – Aggregate real income of the community
P – Purchasing power of money
K – Fraction of real Income Public desires to hold in the form of money.
The Price level
P – M/KY or The value of money (The reciprocal of price level) is
1/P = KY/M

According to Cambridge Equation, the value of money:
Dividing the total quality of goods which the public desires to hold out of the Total Income by Total Supply of Money.
According to Marshall’s Equation, The value of money is influenced not only by changes in M, but also changes in K.

Keynes Equation:
n = pk or p = n/k Where,
n = Total supply of money,
p = general price level of consumption goods,
k = total consumption units people decide to keep as cash.
Keynes says k is a real balance, because it is measured in terms of consumer goods.

According to Keynes, people’s desire to hold money is unaltered by Monetary authority. So price level and value of money can be stablised through regulating quantity of money (n) by Monetary Authority.

Question 14.
Explain disinflation.
Answer:
Disinflation is the slowing down the rate of inflation by controlling the amount of credit.
Eg: Bank Loan, hire purchase available to consumers without causing more unemployment.

Definition of Disinflation:
Disinflation may be defined as the process of revesing Inflation without creating unemployment or reducing output in the Economy.

Question 15.
Illustrate Fisher’s Quantity theory of money.
Answer:
This theory explains the relationship between Quality of money and value of money.
Fisher’s Theory:
He gave a quantitative form in terms of his famous “Equation of Exchange”
MV = PT
The total quantity of money (MV)
Will be equal to
The total value of all goods and services bought and sold (PT)
MV = PT
Supply of Money = Demand for Money (Cash Transaction Equation)
M = Money Supply/Quantity of Money
V = Velocity of Money
P = Price Level
T = Volume of Transaction

P = MV/T
[Note: That is Quantity of money determines the price level and price level values directly with the quantity of money, but provided ‘V’ and ‘T’ remain constant]
Extended Equation of Exchange by Fisher He included Bank deposits M, and its Velocity V’
PT = MV + M’V’
P = MV = MV + M’V’

The price level is determined by:
(i) Quantity of money incirculation ‘M’
(ii) The Velocity of incirculation of money ‘ V’
(iii) The Volume of Bank credit money M<sub>1</sub>
(iv) The Velocity of circulation of credit money V, and the volume of Trade (T)

TN Board 12th Economics Important Questions Chapter 5 Monetary Economics 1

Diagramatic Illustration:
(i) Figure (a) shows the effect of changes in the Quantity of money on the price level. When Quantity of money is OM, the price level is OP.
(ii) When the quantity of money is doubled to OM2, the price level is also doubled to OP2.
(iii) When the quantity of money is increased to OM4 the price level also increases to OP2.
(iv) This is expressed by the curve OP = f (M) from the origin at 45°.
(v) Figure (b) – It gives the inverse relationship between Quantity and Value of money. Value of money on vertical axis and Quantity of money OM, on Horizontal axis, when value of money.
(vi) Is OI/P, the quantity of money is doubled OM2.
(vii) When the value of money becomes \(1 \frac{1}{2} \frac{\mathrm{OI}}{\mathrm{P}_{2}}\) then quantity increases by 4 fold OM4.
(viii) When value of money is reduced by OI/P4, then the inverse relationship between the quantity and value of money is shown by downward sloping curve OI/P = f (M).

TN State Board 12th Economics Important Questions Chapter 4 Consumption and Investment Functions

Question 1.
What is Consumption function?
Answer:
The consumption function is the functional relationship between consumption expenditure and the National income = C = f(Y), C = Consumption, Y = Income, f = Function.

Question 2.
What do you mean by Propensity to Consume?
Answer:
Propensity to consume income and consumption relationship, that is when Income increases, consumption also increases.

Samacheer Kalvi TN Board 12th Economics Important Questions Chapter 4 Consumption and Investment Functions

Question 3.
Define Average Propensity to Consume (APC).
Answer:
“It is the ratio of consumption expenditure to any particular level of income”.
APC = C / Y
Where C = Consumption and Y = Income

Question 4.
Define Marginal Propensity to Consume (MPC).
Answer:
“It is the ratio of change in the consumption to change in income”
MPC = ∆C/∆Y
Where ∆C = change in consumption
∆Y = change in income
MPC is positive but less than unity.

Question 5.
What do you mean by Propensity to Save?
Answer:
It is the proportion of total income or increase in income that consumers save rather than spend on consumption.

Samacheer Kalvi TN Board 12th Economics Important Questions Chapter 4 Consumption and Investment Functions

Question 6.
Define Average Propensity to Save (APS).
Answer:
APS is the quotient obtained by dividing the total saving by the total income. It is the ratio of total savings to total income. It can be expressed in the form of APS = S/Y Where S = savings Y= income

Question 7.
Define Marginal Propensity to Save (MPS).
Answer:
It is the ratio of change in saving to a change in income MPS = ∆S / ∆Y
∆S = change in saving
∆Y = change in income
MPC + MPS =1
MPS = 1 – MPC and MPC = 1 – MPS

Question 8.

Question 16.
Explain Keynes psychological law of consumption function with diagram.
Answer:
This law of consumption which forms the basis of the consumption function. This law Implies that there is a tendency on the part of the people to spend in consumption less than the full increment of income.

Assumptions:

  1. Ceteris paribus: The other variable like tastes, habits etc., do not change.
  2. Existence of normal conditions: The law holds goods under normal conditions.
  3. Existence of a Laissez-Faire Capitalist: This law operates in a rich capitalist economy where there is no government interventions.

Propositions to the law:

  1. Consumption expenditure increases in a smaller amount when the income increases.
  2. The increased income will be divided in some proportion between consumption, expenditure and saving.
  3. Consumption and savings increases when income increases.

Three proportions of the law:

(i) Proposition (1):
When income increases from 120 to 180, consumption also increases from 120 to 170, but the increase in consumption is less than the increase in income.

(ii) Proposition (2):
When income increases to 180 and 240, it divided between consumption by 170 and 220 by the saving by 10 and 20.

(iii) Proposition(3): Increases in income to 180 and 240 lead to increased consumption 170 and 220 and increased saving 20 and 10 than before.

Answer:

TN Board 12th Economics Important Questions Chapter 4 Consumption and Investment Functions 2

Question 18.
Illustrate the working of Multiplier.
Answer:
Working of multiplier – Numerical example:
(i) Investment expenditure undertaken by government is ₹ 100cr (on public work). It is from wages prices of material etc.,
(ii) So income of labourers and suppliers of materials increases by ₹ 100 cr.
(iii) If the marginal propensity to consume is 0.8 that is 80%.
(iv) (A sum of ₹ 80cr is spent on consumption and a sum of ₹ 20cr is saved).

On these basis:
(i) Suppliers of goods get an income of ₹ 80cr
(ii) They spent (80% on ₹ 80cr) ₹ 64cr
(iii) The consumption expenditure and income gives a chain reaction.
The final results is ∆Y = 100 + 100 × 4/5 +100 × [4/5]<sup>2</sup> + 100 × [4/5]<sup>3</sup>or,
∆Y = 100+ 100 × 0.8 + 100 × (0.8)<sup>2</sup> + 100 × (0.8)<sup>3</sup>
= 100 + 80 + 64 + 51.2 = 500

that is 100 × 1/1-4/5 100 × 1 / 1 – 4 / 5
100 × 5 = ₹ 500 crores
For instance if C = 100 + 0.8Y, I = 100,
Then Y =100 + 0.8Y+ 100
0.2Y =200
Y = 200 / 0.2= 1000 → Point B
If I is increased to 110, then ,
0.2Y = 210
Y = 210 / 0.2 = 1050 → Point D

For ₹ 10 increase in I, Y has increased by ₹ 50.
This is due to multiplier effect.
At point A, Y = C = 500
C = 100 + 0.8 (500) = 500; S = 0
At point B, Y = 1000
C = 100 + 0.8 (1000) = 900; S = 100 = I
At point D, Y = 1050
C =100 + 0.8 (1050) = 940; S= 110 = I
When I is increased by 10, Y increases by ₹ 50.
This is multiplier effect (K = 5)
K = \(\frac{1}{0.2}\) = 5

Question 19.
Explain the operation of the Accelerator.
Answer:
(i) To produce 1000 consumer goods 100 machines are required and the life of machine is 10 years, (that is for every 10 years, the machine has to be replaced to maintain to produce 1000 consumer goods). This is called a Replacement Demand.
(ii) If the demand for consumer increases by 10% [ 1000 to 1100] is that case 10 more machines
are needed and the total demand for machines becomes [10 + 10 = 20 ] that is 10 for replacement and 10 for meeting the increased demand.

Note: [The important aspect is 10% increase in demand for consumer goods causes a 100% increase for machines from 10 to 20 No. of machines].

The result derived is:
Even a small change is demand for consumer goods will lead to a big change in investment.

→ When investment is increased from OI2 to OI4, the income also increases from OY, to OY3 and the equilibrium point is E3.
→ If the increase in investment by I2I4 is purely exogenous, then the increase in income by Y1 and Y3 would have been due to multiplier effect.
→ According to this diagram, it is assumed that exogeneous investment is only by I2I3 and induced investment is by I3I4.
→ To conclude, the increase in income by Y1 Y3 is due to the multiplier effect and.
→ The increase in income by Y2Y3 is due to the accelerator effect.

Question 20.
What are the differences between MEC and MEI?
Answer:

Marginal Efliciency of Capital(MEC)

 Marginal Efficiency of Investment(MEI)

It is based on a given supply price for capital. It is based on the induced change in the price due to change in the demand for capital..
It represents the rate of return on all successive units of capital without regard to existing capital. It shows the rate of return on just those units of capital over and above the existing capital stock.
The capital stock is taken on the X axis of diagram. The amount of investment is taken on the X – axis of diagram.
It is a “stock” concept. It is a “flow” concept.
It determines the optimum capital stock in an economy at each level of interest rate. It determines the net investment of the economy at each interest rate given the capital stock.

Question 12.
What do you mean by aggregate demand ? Mention its components.
Answer:
The aggregate demand is the amount of money which entrepreneurs expect to get by selling the output produced by the number, of labourers employed. So it is the expected income or revenue from the sale of output at different levels of employment.
Four components of aggregate demand

  1. Consumption demand
  2. Investment demand
  3. Government expenditure and
  4. Net export (Export – Import)

Question 13.
Explain about aggregate supply with the help of diagram.
Answer:
Aggregate supply is the value of total output of goods and services produced in a year. It is equal to the value of national product i.e., National income. It is the required amount of labourers and materials to produce the necessary output.
Aggregate supply = C + S + T + Rf = Aggregate income generated in the economy.

Explanation of the Diagram:
Aggregate supply curves are drawn for the assumption of fixed money wages and variable wages.
Z curve is Linear and money wages are fixed, curve is non-linear, wage rate increases with employment. When full employment level of Nf is reached, it is impossible to increase output by employing more men. So aggregate supply curve becomes inelastic. (Vertical straight line)

Question 16.
Critically explain Say’s law of market.
Answer:
It is the core of classical theory of employment J.B. say enunciated the proposition that “ supply creates its own demand”. Hence there cannot be general over production or the problem of unemployment in the economy. According to say “ when goods are produced by firms in the economy, they pay reward to the factors of production. So each product produced in the economy creates demand equal to its value in the market”.

TN Board 12th Economics Important Questions Chapter 3 Theories of Employment and Income 5

Assumptions of the Say’s law of market:

  1. The price cannot be affected by single seller, buyer of commodity.
  2. There is full employment.
  3. No single buyer or seller of commodity or an input can affect price.
  4. Full employment.
  5. People are motivated by self interest and self-interest determines economic decisions.

  8. There is wage-price flexibility.
  9. Money acts only as a medium of exchange.
  10. Long – run analysis.
  11.  There is no possibility for over production or unemployment.

Implications of the Say’s law of market:

  1. Over production or unemployment is not possible.
  2. The unutilized resources are employed when factors accept rewards according to their productivity under full employment.
  3. No government intervention due to automatic price mechanism in the economy.
  4. Equality between savings and investment due to flexibility in interest.
  5. Money serves as a medium of exchange only because people will not hold idle money.

Criticisms of Say’s law:

  1. According to Keynes supply does not create its demand. It is not applicable where demand does not increase as much as production increases.
  2. Unemployment can be removed by increase in the rate of investment. Automatic adjustment process will not remove unemployment.
  3. Individuals hold money for unforeseen expenses and businessmen keep cash reserve for future activities. So money is not neutral.
  4. According to say there is no over production but according to Keynes over production is possible.
  5. Because of under employment in capitalist economies, Keynes regards full employment as a special case.
  6. The government intervention arises in the case of general over production and mass unemployment.

Question 17.
Narrate the equilibrium between ADF and ASF with diagram.
Answer:
Equilibrium between ADF and ASF could be explained with household and business sector (Two sector economy). It is assumed that consumption function is linear and planned investment is autonomous.
There are two approaches
(i) Aggregate demand – Aggregate supply approach
(ii) Saving – Investment approach
AD and AS approach is only taken to explain the determination of equilibrium level of income and employment.

TN Board 12th Economics Important Questions Chapter 3 Theories of Employment and Income 6

At the point ‘E’ the AD and AS reach equilibrium. The employment level is N0 at that point. At ON1, employment, the aggregate is N1, R1. But they are able to produce M1, N1.The expected level of profit is M1, R1.

At this level, entrepreneurs will employ more labourers. At the point E, the employment of labour will reach max and it will stop. At the level of beyond ON0 the aggregate demand curve is below the aggregate supply curve. But it will indicate loss to the producers. So they will not employ more than ON0 labour. Equilibrium level of employment need not be the full employment level (N1) the difference between N0 – Nf is the level of unemployment. Sa the concept of effective demand is significant in explaining the under employment equilibrium.
