Question 41 (a).
Discuss the scope of Macro Economics.
The study of macro economics has wide scope and it covers the major areas as follows:
1. National Income: Measurement of national income and its composition by sectors are the basic aspects of macroeconomic analysis. The trends in National Income and its composition provide a long term understanding of the growth process of an economy.

2. Inflation: It refers to steady increase in general price level. Estimating the general price level by constructing various price index numbers such as Wholesale Price Index, Consumer Price Index, etc, are needed.

3. Business Cycle: Almost all economies face the problem of business fluctuations and business cycle. The cyclical movements (boom, recession, depression and recovery) in the economy need to be carefully studied based on aggregate economic variables.

4. Poverty and Unemployment: The major problems of most resource – rich nations are poverty and unemployment. This is one of the economic paradoxes. A clear understanding about the magnitude of poverty and unemployment facilitates allocation of resources and initiating corrective measures.

5. Economic Growth: The growth and development of an economy and the factors determining them could be understood only through macro analysis.

6. Economic Policies: Macro Economics is significant for evolving suitable economic policies. Economic policies are necessary to solve the basic problems, to overcome the obstacles and to achieve growth.

(b) Briefly explain circular flow of Income in a Three Sector Economy.
Circular Flow of Income in a Three-Sector Economy:
Tamil Nadu 12th Economics Model Question Paper 2 English Medium 4

  1. In addition to household and firms, inclusion of the government sector makes this model a three-sector model.
  2. The government levies taxes on households and firms, purchases goods and services from firms, and receive factors of production from household sector.
  3. On the other hand, the government also makes social transfers such as pension, relief, subsidies to the households.
  4. Similarly, Government pays the firms for the purchases of goods and services. The Flow Chart illustrates three-sector economy model:
  5. Under three sector model, national income (Y) is obtained by adding Consumption expenditure (C), Investment expenditure (I) and Government expenditure (G).
  6. Therefore:
    Y = C + I + G.

Question 42 (a).
Explain the importance of national income.
Importance of National Income Analysis:
National income is of great importance for the economy of a country. Nowadays the national income is regarded as accounts of the economy, which are known as social accounts. It enables us-
1. To know the relative importance of the various sectors of the economy and their contribution towards national income; from the calculation of national income, we could find how income is produced, how it is distributed, how much is spent, saved or taxed.

2. To formulate the national policies such as monetary policy, fiscal policy and other policies; the proper measures can be adopted to bring the economy to the right path with the help of collecting national income data.

3. To formulate planning and evaluate plan progress; it is essential that the data pertaining to a country’s gross income, output, saving and consumption from different sources should be available for economic planning.

4. To build economic models both in short – run and long – run.

5. To make international comparison, inter – regional comparison and inter – temporal comparison of growth of the economy during different periods.

6. To know a country’s per capita income which reflects the economic welfare of the country (Provided income is equally distributed)

7. To know the distribution of income for various factors of production in the country.

8. To arrive at many macro economic variables namely, Tax – GDP ratio, Current Account Deficit – GDP ratio, Fiscal Deficit – GDP ratio, Debt – GDP ratio etc.


(b) Explain about aggregate supply with the help of diagram.

  1. Aggregate supply function is an increasing function of the level of employment.
  2. Aggregate supply refers to the value of total output of goods and services produced in an economy in a year.
  3. In other words, aggregate supply is equal to the value of national product, i.e., national income.
  4. Aggregate Supply = C + S + T + Rf = Aggregate income generated in the economy.
  5. The following figure shows the shape of the two aggregate supply curves drawn for the assumption of fixed money wages and variable wages.

Tamil Nadu 12th Economics Model Question Paper 2 English Medium 5

  1. Z curve is linear where money wages remains fixed; Z1 curve is non – linear since wage rate increases with employment.
  2. When full employment level of Nf is reached it is impossible to increase output by employing more men.
  3. So aggregate supply curve becomes inelastic (Vertical straight line).
  4. The slope of the aggregate supply curve depends on the relation between the employment and productivity.
  5. Based upon this relation, the aggregate supply curve can be expected to slope upwards.
  6. In reality the aggregate supply curve will be like Z1.
  7. Therefore, the aggregate supply depends on the relationship between price and wages.

Question 43 (a).
Describe the Say’s Law of Market.

  1. Say’s law of markets is the core of the classical theory of employment.
  2. J.B.Say (1776 – 1832) was a French Economist and an industrialist.
  3. He was influenced by the writings of Adam Smith and David Ricardo.
  4. J.B. Say enunciated the proposition that “Supply creates its own demand”.
  5. Hence there cannot be general over production or the problem of unemployment in the economy.
  6. According to Say, “When goods are produced by firms in the economy, they pay reward to the factors of production.
  7. The households after receiving rewards of the factors of production spend the amount on the purchase of goods and services produced by them.
  8. Therefore, each product produced in the economy creates demand equal to its value in the market.
  9. In short, this classical theory explains that “A person receives his income from production which is spent on the purchase of goods and services produced by others.
  10. For the economy as a whole, therefore, total production equals total income”.


(b) Explain Marginal Propensity to Consume [MPC] and Multiplier with diagram and Diagrammatic explanation.
Marginal propensity to consume and multiplier:
Tamil Nadu 12th Economics Model Question Paper 2 English Medium 6
The propensity to consume refers to the portion of income spent on consumption.
The MPC refers to the relation between change in consumption (C) and change in income (Y).
Symbolically MPC = AC/AY The value of multiplier depends on MPC
Multiplier (K)= 1/1-MPC The multiplier is the reciprocal of one minus marginal propensity to consume.
Since marginal propensity to save is 1 – MPC. (MPC + MPS = 1). Multiplier is 1/ MPS. The multiplier is therefore defined as reciprocal of MPS.
Multiplier is inversely related to MPS and directly with MPC.
Numerically if MPC is 0.75, MPS is 0.25 and k is 4.
Using formula k = 1/1 – MPC
1/1 – 0.75 = 1/0.25 = 4
Taking the following values, we can explain the functioning of multiplier.

0.00 1.00 1
0.10 0.90 1.11
0.50 0.50 2.00
0.75 0.25 4.00
0.90 0.10 10.00
1.00 0.00 α

C = 100 + 0.8 y;
I = 10
Y = C + I
Y= 100 + 0.8y + 100
0. 2y = 200
Y= 1000
Here, C = 100 + 0.8y = 100 + (1000) = 900;
S= 100 = I
After I is raised by 10, now I = 110,
Y = 100 + 0.8y + 110
0. 2y = 210
y = \(\frac{210}{0.2}\) = 1050
Here C = 100 = 0.8 (1050) = 940; S = 110 = I
Diagrammatic Explanation.
At 45° line y = C + S
It implies the variables in axis and axis are equal.
The MPC is assumed to be at 0.8 (C = 100 + 0.8y)
The aggregate demand (C +1) curve intersects 45° line at point E.
The original national income is 500.
(C = 100 + 0.8y = 100 + 0.8 (500) = 500) ,
When I is 100, y = 1000, C = 900;
S = 100 = I
The new aggregate demand curve is C + F = 100 + 0.8y + 100 + 10
y = \(\frac{210}{0.2}\) = 1050
S = 110 = I

Question 44 (a).
Write the types of inflation.
The four types of inflation are
(i) Creeping Inflation: Creeping inflation is slow-moving and very mild. The rise in prices will not be perceptible but spread over a long period. This type of inflation is in no way dangerous to the economy. This is also known as mild inflation or moderate inflation.

(ii) Walking Inflation: When prices rise moderately and the annual inflation rate is a single digit (3% – 9%), it is called walking or trolling inflation.

(iii) Running Inflation: When prices rise rapidly like the running of a horse at a rate of speed of 10% – 20% per annum, it is called running inflation.

(iv) Galloping inflation: Galloping inflation or hyper inflation points out to unmanageably high inflation rates that run into two or three digits. By high inflation the percentage of the same is almost 20% to 100% from an overall perspective.

Other types of inflation (on the basis of inducement):

  1. Currency inflation: The excess supply of money in circulation causes rise in price level.
  2. Credit inflation: When banks are liberal in lending credit, the money supply increases and thereby rising prices.
  3. Deficit induced inflation: The deficit budget is generally financed through printing of currency by the Central Bank. As a result, prices rise.
  4. Profit induced inflation: When the firms aim at higher profit, they fix the price with higher margin. So prices go up.
  5. Scarcity induced inflation: Scarcity of goods happens either due to fall in production (e.g. farm goods) or due to hoarding and black marketing. This also pushes up the price. (This has happened is Venezula in the year 2018).
  6. Tax induced inflation: Increase in indirect taxes like excise duty, custom duty and sales tax may lead to rise in price (e.g. petrol and diesel). This is also called taxflation.


(b) What are the functions of NABARD?
Functions of NABARD:
NABARD has inherited its apex role from RBI i.e, it is performing all the functions performed by RBI with regard to agricultural credit.
(i) NABARD acts as a refinancing institution for all kinds of production and investment credit to agriculture, small-scale industries, cottage and village industries, handicrafts and rural crafts and real artisans and other allied economic activities with a view to promoting integrated rural development.

Question 45 (a).
Briefly explain facilities offered by IMF.
Facilities offered by IMF:
The Fund has created several new credit facilities for its members. Chief among them are:
(i) Basic Credit Facility:

  • The IMF provides financial assistance to its member nations to overcome their temporary difficulties relating to balance of payments.
  • A member nation can purchase from the Fund other currencies or SDRs, in exchange for its own currency, to finance payment deficits.
  • The loan is repaid when the member repurchases its own currency with other currencies or SDRs.
  • A member can unconditionally borrow from the Fund in a year equal to 25% of its quota.
  • This unconditional borrowing right is called the reserve tranche.

(ii) Extended Fund Facility:

  • Under this arrangement, the IMF provides additional borrowing facility up to 140% of the member’s quota, over and above the basic credit facility.
  • The extended facility is limited for a period up to 3 years and the rate of interest is low.

(iii) Compensatory Financing Facility:

  • In 1963, IMF established compensatory financing facility to provide additional financial assistance to the member countries, particularly primary producing countries facing shortfall in export earnings.
  • In 1981, the coverage of the compensatory financing facility was extended to payment problem caused by the fluctuations in the cost of cereal inputs.

(iv) Buffer Stock Facility:

  • The buffer stock financing facility was started in 1969.
  • The purpose of this scheme was to help the primary goods (food grains) producing countries to finance contributions to buffer stock arrangements for the stabilisation of primary product prices.

(v) Supplementary Financing Facility:
Under the supplementary financing facility, the IMF makes temporary arrangements to provide supplementary financial assistance to member countries facing payments problems relating to their present quota sizes.

(vi) Structural Adjustment Facility:

  1. The IMF established Structural Adjustment Facility (SAF) in March 1986 to provide additional balance of payments assistance on concessional terms to the poorer member countries.
  2. In December 1987, the Enhanced Structural Adjustment Facility (ESAF) was set up to augment the availability of concessional resources to low income countries.
  3. The purpose of SAF and ESAF is to force the poor countries to undertake strong macroeconomic and structural programmes to improve their balance of payments positions and promote economic growth.
