Question 42 (a).
Discuss the economic determinants of economic development.
Determinants of Economic Development:
Economic development is not determined by any single factor. Economic development depends on Economic, Social, Political and Religious factors.
Economic and Non-Economic Factors:
Tamil Nadu 12th Economics Model Question Paper 1 English Medium 6
Economic Factors:
1. Natural Resource: The principal factor affecting the development of an economy is the availability of natural resources. The existence of natural resources in abundance is essential for development.

2. Capital Formation: Capital formation is the main key to economic growth. Capital formation refers to the net addition to the existing stock of capital goods which are either tangible like plants and machinery or intangible like health, education and research.

3. Size of the Market: Large size of the market would stimulate production, increase employment and raise the National per capita income. That is why developed countries expand their market to other countries through WTO.

4. Structural Change: Structural change refers to change in the occupational structure of the economy. Any economy of the country is generally divided into three basic sectors: Primary sector such as agricultural, animal husbandry, forestry, etc; Secondary sector such as industrial production, constructions and Tertiary sector such as trade, banking and commerce.

5. Financial System: Financial system implies the existence of an efficient and organized banking system in the country.

6. Marketable Surplus: Marketable surplus refers to the total amount of farm output cultivated by farmers over and above their family consumption needs. This is a surplus that can be sold in the market for earning income.

7. Foreign Trade: The country which enjoys favorable balance of trade and terms of trade is always developed. It has huge forex reserves and stable exchange rate.

8. Economic System: The countries which adopt free market mechanism (laissez faire) enjoy better growth rate compared to controlled economies.

Non-Economic Factors:
‘Economic Development has much to do with human endowments, social attitudes, political conditions and historical accidents. Capital is a necessary but not a sufficient condition of progress.’
1. Human Resources: Human resource is named as human capital because of its power to increase productivity and thereby national income. There is a circular relationship between human development and economic growth. A healthy, educated and skilled labour force is the most important productive asset. Human capital formation is the process of increasing knowledge, skills and the productive capacity of people.

2. Technical Know-how: As the scientific and technological knowledge advances, more and more sophisticated techniques steadily raise the productivity levels in all sectors.

3. Political Freedom: The process of development is linked with the political freedom.

4. Social Organization: People show interest in the development activity only when they feel that the fruits of development will be fairly distributed.

5. Corruption free administration: Corruption is a negative factor in the growth process. Unless the countries root-out corruption in their administrative system, the crony capitalists and traders will continue to exploit national resources.

6. Desire for development: The pace of economic growth in any country depends to a great extent on people’s desire for development.

7. Moral, ethical and social values: These determine the efficiency of the market, according to Douglas C. North. If people are not honest, market cannot function.

8. Casino Capitalism: If People spend larger proportion of their income and time on entertainment liquor and other illegal activities, productive activities may suffer, according to Thomas Piketty.

9. Patrimonial Capitalism: If the assets are simply passed on to children from their parents, the children would not work hard, because the children do not know the value of the assets.

(b) Critically explain say’s law of market.
Criticisms of Say’s Law:
The following are the criticisms against 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. Automatic adjustment process will not remove unemployment. Unemployment can be removed by increase in the rate of investment.
  3. Money is not neutral. Individuals hold money for unforeseen contingencies while businessmen keep cash reserve for future activities.
  4. Say’s law is based on the proposition that supply creates its own demand and there is no over production. Keynes said that over production is possible.
  5. Keynes regards full employment as a special case because there is under – employment in capitalist economies.
  6. The need for state intervention arises in the case of general over production and mass unemployment.

Question 43 (a).
Explain the importance of National Income analysis.
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) Briefly explain the relationship between GDP growth and the quality of environment.
Tamil Nadu 12th Economics Model Question Paper 1 English Medium 7

Question 44 (a).
Illustrate the working of multiplier.
Working of Multiplier:

  1. Suppose the Government undertakes investment expenditure equal to Rs 100 crore on some public works, by way of wages, price of materials etc.
  2. Thus income of labourers and suppliers of materials increases by Rs 100 crore. Suppose the MPC is 0.8 that is 80 %.
  3. A sum of Rs 80 crores is spent on consumption (A sum of Rs 20 Crores is saved).
  4. As a result, suppliers of goods get an income of Rs 80 crores.
  5. They intum spend Rs 64 crores (80% of Rs 80 cr).
  6. In this manner consumption expenditure and increase in income act in a chain like maimer.

The final result is ΔY = 100 + 100 × 4/5 + 100 × [4/5]² + 100 × [4/5]³ or,
ΔY = 100 + 100 × 0.8 + 100 × (0.8)² + 100 × (0.8)³
= 100+ 80 + 64+ 51.2… = 500
that is 100 × 1/1 = 4/5
100 × 1/1/5
100 × 5 = Rs 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 Rs 10 increase in I, Y has increased by Rs 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 = \(\frac{1}{0.2}\)


(b) Bring out the components of balance of payments accounts.
Components of BOPs:
The credit and debit items are shown vertically in the BOP account of a country. Horizontally, they are divided into three categories, i.e.,

  1. The current account,
  2. The capital account and
  3. The official settlements account or official reserve assets account.

1. The Current Account: It includes all international trade transactions of goods and services, international service transactions (i.e. tourism, transportation and royalty fees) and international unilateral transfers (i.e. gifts and foreign aid).

2. The Capital Account: Financial transactions consisting of direct investment and purchases of interest-bearing financial instruments, non-interest bearing demand deposits and gold fall under the capital account.

3. The Official Reserve Assets Account: Official reserve transactions consist of movements of international reserves by governments and official agencies to accommodate imbalances arising from the current and capital accounts.

The official reserve assets of a country include its gold stock, holdings of its convertible foreign currencies and Special Drawing Rights (SDRs) and its net position in the International Monetary Fund (IMF).

Question 45 (a).
Explain in detail the measures to control inflation.
Measures to Control Inflation
Keynes and Milton Friedman together suggested three measures to prevent and control of inflation.

  1. Monetary measures,
  2. Fiscal measures (J.M. Keynes) and
  3. Other measures.

1. Monetary Measures: These measures are adopted by the Central Bank of the country. They are (i) Increase in Bankrate (ii) Sale of Government Securities in the Open Market (iii) Higher Cash Reserve Ratio (CRR) and Statutory Liquidity Ratio (SLR) (iv) Consumer Credit Control and (v) Higher margin requirements (vi) Higher Repo Rate and Reverse Repo Rate.

2. Fiscal Measures: Fiscal policy is now recognized as an important instrument to tackle an inflationary situation. The major anti-inflationary fiscal measures are the following: Reduction of Government Expenditure, Public Borrowing and Enhancing taxation.

3. Other Measures: These measures can be divided broadly into short-term and long-term measures.
i) Short-term measures can be in regard to public distribution of scarce essential commodities through fair price shops (Rationing). In India whenever shortage of basic goods has been felt, the government has resorted to import so that inflation may not get triggered.
ii) Long-term measures will require accelerating economic growth especially of the wage goods which have a direct bearing on the general price and the cost of living. Some restrictions on present consumption may help in improving saving and investment which may be necessary for accelerating the rate of economic growth in the long run.
