Gross National Product refers to gross money value of all final goods and services produced in the country during one accounting year, including net income from abroad. 2. GNP = C + I + G + (X – M) + (R – P) 3. GNP includes income earned by Indian Nationals within or outside the country. Gross Domestic Product (GDP): 1. Gross Domestic Product refers to gross money value of all final goods and services produced within the domestic boundaries of a country during one accounting year. 2. GDP = C + I + G + (X-M) 3. GDP does not include income earned by Indian national outside the country. Question 2. Net National Product (NNP) and Net Domestic Product (NDP). Answer: Net National Product (NNP): 1.

Net Domestic Product (NDP): 1. NDP is net value of all final goods and services produced within the domestic boundaries of the country. 2. It does not include income earned by the Indian Nationals outside the country. 3. NDP = C + I + G + (X-M)- Depreciation 4. NDP will be less than NNP if (R – P) is positive and it can be more than NNP if (R – P) is negative. Question 3. Output Method Or Product Method and Income Method Or Factor Cost. Answer: Output Method Or Product Method: 1. According to the product or output method, National Income is estimated by adding up the value of all final goods and services produced in the country during one year. 2. NI = C+I+G+(X-M)+(R – P) – Depreciation – Income Tax + Subsidies 3. In India, this method is applied to agriculture, mining and manufacturing. 4. Here we look at National Income from production side. 5. In this method we deduct indirect tax and then add subsidies to arrive at National Income at Factor Cost from Market Price. Income Method Or Factor Cost: 1. According to Income method the National Income is estimated by adding the factor Incomes that accrue to factors of production by way of rent, wages, interest and profit. 2. NI = R + W + I + P + MI + (X-M) + (R-P) – Depreciation – Transfer Income. 3. In India this method is used by National Income Committee in trade, transport, professionals, liberal arts, public administration. 4. Here we look at National Income from distribution side. 5. This method is a direct method as we arrive at National Income at factor cost. Question 4. Gross National Product (GNP) and Net National Product (NNP). (Feb. ‘16; Oct. ‘15) Answer: Gross National Product (GNP): 1. Gross National Product refers to gross money value of all final goods and services produced in an economy during a year. It includes net income from abroad. 2. Depreciation cost of capital assets are included. 3. GNP = C + I + G + (X-M) + (R-P)Or GNP = NNP + Depreciation 4. GNP value does not give us a true picture of the net increase in the production of the economy. 5. It is a wider concept. It includes NNP. 6. GNP will be greater than NNP. Net National Product (NNP) 1. Net National Product refers to the net money value of all goods and services produced in an economy during a year. It includes net income from abroad. 2. Depreciation cost of capital assets are not included. 3. NNP = GNP – Depreciation Or NNP = C + I + G + (X-M) + (R – P) – Depreciation 4. NNP is a better measure of National Income. It is a better index of judging the progress of the economy at any time. 5. It is narrow concept. It is a part of GNP. 6. NNP will be less than GNP. Question 5. Illegal Income and Transfer Income. Answer: Illegal Income: 1. Illegal income means income which is earn from illegal activities. 2. E.g. Income from gambling, black marketing, theft, smuggling, etc. Transfer Income: 1. Transfer income means money from the government in the form of benefits. 2. E.g. income from pension, gift, unemployment allowance, etc. Question 6. Two Sector economy and Three Sector economy. Answer: Two Sector economy: • In this economy flow of goods and money is circulated in households and business firms. • Symbolically – Y = C + I Three Sector economy: • In this economy flow of goods and money is circulated in households, business firms and government sector. • Symbolically – Y= C + I + G. Question 7. Three Sector economy and Four Sector economy. Answer: Three Sector economy: 1. In this economy, flow of goods and money is circulated in households, business firms and government sector. 2. Symbolically – Y = C + I + G Four Sector economy: 1. In this economy, flow of goods and money is circulated in households, business firms, government sector and foreign sector. 2. Symbolically – Y= C + I + G + (X-M) Question 8. Income Method and Expenditure Method. Answer: Income Method: 1. It is the sum of income earn by all factors of production in a year. 2. In this method, national income is estimated from the distribution side 3. Symbolically – NI = R + W + I + MI + (X-M) 4. This method is extremely popular in developed countries. Expenditure Method: 1. It is the sum of expenditure incurred by private sector and government on consumption and investment in a year. 2. In this method, national income is estimated from the expenditure side. 3. Symbolically -NI = C + I + G + (X-M) + (R-P) 4. This method is very rarely used by any country. Question 9. Closed Economy and Open Economy. Answer: Closed Economy: 1. It is an economy which is not open to international trade and foreign investment. 2. In a closed economy only the values of goods and services produced within the country are considered in the N.I. estimate. 3. Net exports and net factor income from abroad are not included. 4. GNP = GDP + C + I + G. Open Economy: 1. It is an economy which is open to international trade and foreign investment. 2. In an open economy the values of goods and services produced within the country as well as net exports and net factor income from abroad are also considered in N.I. estimate. 3. Net exports and net factor income from abroad are included. 4. GDP(MP) = C + I + G + (X – M) GNP(MP) = GDP + (R – P) = C + I + 0 + (X – M) + (R – P) Question 10. Product / Output Method and Expenditure Method. Answer: Output Method Or Product Method: 1. According to the product or output method, National Income is estimated by adding up the value of all final goods and services produced in the country during one year. 2. NI = C+I+G+(X-M)+(R – P) – Depreciation – Income Tax + Subsidies 3. In India, this method is applied to agriculture, mining and manufacturing. 4. Here we look at National Income from production side. 5. In this method we deduct indirect tax and then add subsidies to arrive at National Income at Factor Cost from Market Price. Expenditure Method: 1. It is the sum of expenditure incurred by private sector and government on consumption and investment in a year. 2. In this method, national income is estimated from the expenditure side. 3. Symbolically -NI = C + I + G + (X-M) + (R-P) 4. This method is very rarely used by any country. 3. Answer the following questions: Question 1. Explain the income method of measuring National Income. Answer: Meaning: In general sense of the term ‘National Income’ refers to the total money value of all final goods and services produced in the country during a period, usually one year. It includes net income from abroad. But does not include depreciation. Definitions: • Prof. AC. Pigou: ‘The national dividend is that part of the objective income of the community including of course income derived from abroad, which can be measured in money.” • Prof. Irving Fisher: “National dividend or income consists solely of services as received by ultimate consumers whether from their material or from their human environments.” • National Income Committee: “A National Income estimate measures the volume of commodities and services turned out during a given period counted without duplication.” Here, the National Income is calculated without double counting. Question 2. Explain the expenditure method of measuring National Income. Answer: (B) Expenditure Method : This method also known as outlay method. NI = C + I + G + (X – M) + (R – P) National Income can also be calculated by adding up the expenditure incurred on purchase of final goods and services. We can get National Income by summing up all consumption expenditure, investment expenditure made by all individuals, firms as well as the government of a country during a year. • Consumption Expenditure (C) : It includes all expenditure incurred on goods and services by households during the year. It includes expenditure mostly on durable and non-durable goods, which are consumed by the consumers. E.g. food, medical care, clothing, car, computer and services, etc. • Investment Expenditure (I) : It refers to the investment made by private businessman on capital goods like machinery, plants, factories, warehouses, etc. • Government Expenditure on goods and services (G) : Government expenditure refers to expenditure on consumption and investment – • Consumption expenditure : It refers to expenditure incurred on various administrative services like law and order, defence education, generation and distribution of electricity. • Investment expenditure : It refers to expenditure incurred by government on construction of roads, railways, dams, canals, etc. • Net Exports (X – M): It refers to difference between exports and imports of the country. If the exports are more than imports then net exports will be positive, it is called Trade Surplus and if imports are greater than exports, the net exports will be negative, it is called as Trade Deficit. • Net Receipts (R-P) : It is the difference between expenditure incurred by foreigners in the country (R) and expenditure incurred abroad by Nationals (P). Net Receipts can also be Positive or Negative. Net National Expenditure = NNE = C + I + G + (X – M) + (R – P) – Depreciation. NNPFC or NI = C + I + G + (X -M) + (R -P) “Depreciation “ Indirect Tax + Subsidies. Precautions : The following precautions should be taken while estimating National Income. • To avoid double counting take the expenditure incurred only on final goods and services. • Government expenditure on transfer payments to be excluded like unemployment allowances, old age pension etc. • Expenditure on second hand goods like furniture, house, land and financial assets { like shares, bonds, etc. should be excluded. • Exclude expenditure incurred on purchase of financial assets such as shares, bonds, etc. • Deduct indirect tax and add subsidies. Out of these methods, output method and income method are extensively used. Expenditure method is rarely used because of its practical difficulties. In India, the Central Statistical Organisation (CSO) adopts a combination of output method and income method to estimate N.I. of India. Question 3. Give the definitions of National Income. Answer: Meaning: In general sense of the term ‘National Income’ refers to the total money value of all final goods and services produced in the country during a period, usually one year. It includes net income from abroad. But does not include depreciation. Definitions: • Prof. AC. Pigou: ‘The national dividend is that part of the objective income of the community including of course income derived from abroad, which can be measured in money.” • Prof. Irving Fisher: “National dividend or income consists solely of services as received by ultimate consumers whether from their material or from their human environments.” • National Income Committee: “A National Income estimate measures the volume of commodities and services turned out during a given period counted without duplication.” Here, the National Income is calculated without double counting. 4. State with reasons whether you agree or disagree with the following statements: Question 1. National Income is important to formulate only economic policies. Answer: No, I do not agree with this statement. National Income data is important for many other purposes, like – • For the Economy : National Income data are very important for marco economic analysis and performance of the economy. • Economic Planning: The data of National Income is very important tools for long term and short term economic planning. • Economic Research: The data of National [ Income is very useful to the research students to study aggregate consumption expenditure, investment expenditure, etc. • Speed of Economic Growth : National Income makes it possible to know the trends or speed of the economic growth of our ( country in relation to previous years. Question 2. Income from second hand sale of goods is excluded from National Income. Answer: Yes, I agree with this statement. • National Income includes only the money value of final goods and services produced in ( the current year. • Income from sale and purchase of second hand goods is not included in National Income because these goods are not a part of current years production. Their value was included in the National Income of that year in which they were produced. • As the wealth of the country remains the same if they are included in the current years National Income it will lead to double counting. • So, National Income figures will get inflated due to over estimation. Question 3. National Income at factor cost includes subsidy. Answer: Yes, I agree with this statement. • National Income at factor cost is the income earned by the factor owners (landlord, labourer, capitalist) in the course of contributing to the country’s output. • NI(FC) = C + I + G + (X – M)+ (R – P) – Depreciation – Indirect Tax + Subsidies • Subsidies is a negative tax. It is a sought of concession or discount given by the government to the consumers and producers. • Subsidies are paid by the government to the firms / producers. • Also the goods are sold at a price lower than their cost. • Subsidies reduce the price of product below the factor cost. So to arrive at N.I. at factor cost we add subsidies. Question 4. National Income estimates are not accurate in India. Answer: Yes, I agree with this statement. There are many statistical difficulties faced in the estimation of National Income due to which N.I. estimates are not accurate. They are as follows : • There is the danger of double counting by including the value of intermediate goods. • Inadequate and unreliable information regarding income and expenditure leads to inaccuracy in estimating N.I. • In India, people are illiterate and ignorant, so they do not maintain proper accounts. • To evade tax people do not reveal their exact income. • The sources from which data are obtained are not absolutely reliable. • Statistical staff are untrained and inefficient. Question 5. Old age pension is transfer income. Answer: Yes, I agree with this statement. • Transfer Income are income received by individuals without contributing anything to the current years production of goods and services. It is a flow of money without a reverse flow of goods or services. • Old age pension is received by a person after he retires from work. • To get this income tlje person actually does not contribute anything to production of goods and services during that period. • Old age pension is income transferred from the government. • So it is a government expenditure. • Transfer income are included in personal income. But they are not included in National Income because such payments do not result in any addition to the total production of goods. Question 6. Paid services are included in National Income. OR Unpaid services are not included in National Income. (Mar. ‘15; Oct. ‘15) Answer: Yes, I agree with this statement. • In economic sense paid services refer to economic production which means they are production of those goods and services which are meant for sale and have market value. • Paid services are marketable. They have exchange value. We can determine its price and so it can be included in National Income. • Unpaid services cannot be marketed so they cannot be included in National Income. Although these services contribute to human welfare. • E.g. service of housewife. It is non-economic production, which is not marketable. • National Income is the sum of money value of all goods and services produced during the year by the resources of a country. Question 7. National Income is an important tool to measure the overall performance of the economy. OR The concept of National Income has an important place in Economic development. Answer: Yes, I agree with this statement. • National Income is one of the important indicators of economic growth and development. • National Income is a macro variable that represents the economy as a whole. • When there is an increase in National Income it indicates that the country’s production of goods and services have increased, employment increases, trade with rest of the world increases. • When National Income of a country increases at a higher rate than the rate of increase in population, it leads to improvement in the standard of living and welfare of the people. • The Per Capita Income also increases when National Income increases. • Therefore, National Income is an important tool to measure the overall performance of the economy. Question 8. The services of housewife (unpaid services) is included in National Income. Answer: No, I do not agree with this statement. OR Services of housewives are excluded from National Income. Answer: Yes, I agree with this statement. • The National Income is the sum of money value of all goods and services produced during the year by the resources of a country. • But the goods and services which do not have exchange value or market value are not included in National Income as they are non-economic production. • Service of housewife is not considered an economic activity as it is non – economic production and so it does not have exchange value or market value. • Housewife is not paid by family members. • Therefore, the service of housewife is not included in National Income but the service of a maid servant is included. Question 9. Illegal income is not included in National Income. Answer: Yes, I agree with this statement. • The existence of a parallel or black economy is a common feature of most of the economies. • Productive activities in this sector are either concealed or under reported and as a result the income generated remain unreported. It is rather difficult to estimate this income correctly. So they are not included in National Income. • For example income originating from activities as smuggling, black-marketing, gambling, selling harmful drugs, etc. are excluded from National,Income. • Many rich people, businessmen and landlords hide their property and wealth. No authorised registration is available for the income received so they are not included. Question 10. Transfer income is included in National Income. Answer: No, I do not agree with this statement. OR Transfer Income cannot be included in National Income. Answer: Yes, I agree with this statement. • Transfer income is income received by individuals without contributing to the current years production of goods and services. • Transfer income received by people in the form of old age pension, gifts, lottery prize etc. are not included in National Income. • These incomes are included in Personal Income but not in National Income. • All transfer income are actually earned by some other people, by contributing to production originally and then transferred to another. • If such incomes are counted at both places two times, there will be a double counting. • Therefore, to avoid double counting and to get accurate estimation, transfer incomes are not included in National Income. National Income includes only income from production of goods and services. Question 11. National Income is a stock / reserve concept. Answer: No, I do not agree with this statement. OR National Income is not a stock. It is a flow concept. Answer: Yes, I agree with this statement. • National income is a flow concept. • National income is expressed per year. • National income refers to money value of all goods and services produced by the economy in a year. • It considers the production of current year and not previous year. 5.

6. Answer in detail;

Question 1.
What is national income? Explain theoretical conceptual difficulties in the calculation of national income.
Answer:
National income means money value of goods and services produced in the country in a year.
According to National Income committee:
“A national income estimate, measures the volume of goods and services turned out during a given period without duplication. There are many practical difficulties in the measurement of NI.

• Transfer payment: If it included in national income then there will be overestimation of NI. E.g. pension, gifts, unemployment allowances, etc. are excluded.
• Unpaid services : The value of unpaid services are not included in national income as they are not paid for. E.g. services of housewife.
• Illegal income : The income from illegal activities are not included in NI. E.g. black marketing, smuggling.
• Production for self-consumption: It is very difficult to get data and value of goods kept for self-consumption as they do not enter market.
• Income of foreign firms : Income of foreign firm should be included in the national income of the country where the firm undertakes production work. But the profit earn by these firms are transferred to their home own country.

Question 2.
Explain the difficulties in measuring National Income.
Answer:
National income means money value of goods and services produced in the country in a year.
According to National Income committee:
“A national income estimate, measures the volume of goods and services turned out during a given period without duplication. There are many practical difficulties in the measurement of NI.

(A) Theoretical difficulties

• Transfer payment: If it included in national income then there will be overestimation of NI. E.g. pension, gifts, unemployment allowances, etc. are excluded.
• Unpaid services : The value of unpaid services are not included in national income as they are not paid for. E.g. services of housewife.
• Illegal income : The income from illegal activities are not included in NI. E.g. black marketing, smuggling.
• Production for self-consumption: It is very difficult to get data and value of goods kept for self-consumption as they do not enter market.
• Income of foreign firms : Income of foreign firm should be included in the national income of the country where the firm undertakes production work. But the profit earn by these firms are transferred to their home own country.

(B) Practical Difficulties or Statistical Difficulties:

• Problem of double counting: In case of certain goods it is difficult to distinguish properly between final goods and intermediate goods. That’s why problem of double counting arises e.g. flour is final goods for housewife, but it is intermediate goods for the bakery.
• Existence of non-monetised sector: In India large non-monetised sector exists in rural area specially in agriculture. In agriculture, many places goods and services are exchanged with goods that’s why it is difficult to count in national income.
• Inadequate and unreliable data: Because of illiteracy it is difficult to get adequate and reliable data from unorganised sector, small enterprises, agriculture, etc.
• Depreciation: Its difficult to measure exact value of depreciation. There are no uniform common accepted standard rates of depreciation applicable to the various capital assets.
• Capital gain or loss: Due to capital gain there is overestimation and due to capital loss there is underestimation of national income.
• Illiteracy and ignorance: Majority of small producer in developing counties are illiterate and ignorant and are not able to keep accounts of their productive activities.
• Lack of systematic, occupational classification: There is lack of systematic occupational classification, which makes the calculation of national income difficult. Especially in rural areas where many villagers work on farms for some time and also take some other job during offseason.
• Untrained and incompetent staff: Due to untrained and incompetent staff, accurate and timely, information cannot be obtained.

Question 3.
What is National Income? Explain the Output method of measuring National Income.
Answer:
Product Method or Output Method: This method is also called as Inventory Method.
According to this method economy is divided into various sectors like agriculture, mining, manufacturing, small enterprises, commerce, transport, communication, etc.

National income by this method can be calculated by either valuing all final goods and services
produced during a year at their market price or by adding up all values at each higher stage of
production, until these products are turned into final products.

In output method there are two approaches to measure national income.

(1) Final Goods Approach I Final Product Approach : According to this approach, value of all final goods and services produced in primary, secondary and tertiary sector are included and the value of all intermediate transactions are ignored.

2. Value Added Approach I Value Added Method: To avoid double-counting, the value-added approach is used to estimate the National Income. According to this method, it is necessary to obtain the total of value-added at each stage in the manufacture of a commodity to arrive at Gross National Product. The value-added method can be explained by means of a simple example.

(a) In the above example, value of groundnut with shell is 50, after removing shells value of groundnut is 80, after crushing groundnut the value is 120 and when oil is packed in the packets its value is 150.
To avoid double-counting either the value of final output or the value – added should be taken in estimation of National Income.

The output method is widely used in the underdeveloped countries. In India, this method is applied in agriculture, mining and manufacturing sector.

Precautions:

• Avoid Double Counting: The value of only final goods and services must be considered and not the value of raw – materials or intermediary goods, etc.
• Self Consumption Goods: Goods used for self-consumption by farmers should be included in National Income.
• Price Level Changes to be considered: The values of national output must be expressed in terms of prices in some base year to know the national output in real terms i.e. N.I. at constant price.
• Net Income from Abroad: Care should be taken to include net income from abroad in National Income.
• Depreciation: Depreciation of capital assets should be deducted from the value of gross investment during the year.
• Indirect Taxes and Subsidies: To get National Income, deduct the indirect tax from the market price and add subsidies.
• Second-Hand Goods: Sale and purchase of second-hand goods should be ignored as it is not a part of current production.

Question 4.
Explain the various method of measuring National Income. ?
Answer:
National Income is macro economic concept. National Income means money value of goods and services produced in the country in a year. There are three methods to measure national income.
(1) The Output Method,
(2) The Income Method,
(3) The Expenditure Method.

(A) The Income Method : This method is also known as factor cost method. According to this method national income is the sum of income received by all factors of production in a year. So national income is the income received by all the citizens of the country in a year. In income method national income studied from the distribution side. According to income method national income or GNP is
NI = R + W + I + P + MI + (X – M)

• Rent (R) : Rent and Royalty is usually treated as the payment for the land, building, machines that are rented.
• Wages (W) : It includes wages and salaries earned by labour as well as it includes commission, bonus, social security payments, fringe benefits, etc.
• Interest (I) : Interest is the payment for using the services of capital. It includes interest paid by banks, insurance companies etc.
• Profit (P) : It includes the profit of private and public sector companies.
• Mixed Income (MI) : It is the income which is earned by self-employed. They earn income through various sources like wages for effort put, rent on own property, interest on own capital, etc.
• Net Exports (X – M) : It is the difference between export and imports.

Precautions :

• Transfer payment : It should not be included in national income. E.g. pension, gifts, unemployment allowances, lottery prize, etc.
• Unpaid services : It should not be included in national income. E.g. services of housewife, teacher teaching her own child, etc.
• Second hand goods : The income from sale of second hand goods should not be included.
• Financial asset : The income from sale of shares and bonds should not be included in national income.
• Tax revenue : The revenue of government through taxes should not be included in national income.
• Undistributed profits of companies, income from government property and profits from public enterprise should be included.
• Imputed value of production kept for self consumption and rental value of owner occupied houses should be included in national income.

(B) Expenditure Method :
This method also known as outlay method. NI = C + I + G + (X – M) + (R – P)
National Income can also be calculated by adding up the expenditure incurred on purchase of final goods and services. We can get National Income by summing up all consumption expenditure, investment expenditure made by all individuals, firms as well as the government of a country during a year.

• Consumption Expenditure (C) : It includes all expenditure incurred on goods and services by households during the year. It includes expenditure mostly on durable and non-durable goods, which are consumed by the consumers. E.g. food, medical care, clothing, car, computer and services, etc.
• Investment Expenditure (I) : It refers to the investment made by private businessman on capital goods like machinery, plants, factories, warehouses, etc.
• Government Expenditure on goods and services (G) : Government expenditure refers to expenditure on consumption and investment –
• Consumption expenditure : It refers to expenditure incurred on various administrative services like law and order, defence education, generation and distribution of electricity.
• Investment expenditure : It refers to expenditure incurred by government on construction of roads, railways, dams, canals, etc.
• Net Exports (X – M): It refers to difference between exports and imports of the country. If the exports are more than imports then net exports will be positive, it is called Trade Surplus and if imports are greater than exports, the net exports will be negative, it is called as Trade Deficit.
• Net Receipts (R-P) : It is the difference between expenditure incurred by foreigners in the country (R) and expenditure incurred abroad by Nationals (P). Net Receipts can also be Positive or Negative.
Net National Expenditure = NNE = C + I + G + (X – M) + (R – P) – Depreciation. NNPFC or NI = C + I + G + (X -M) + (R -P) “Depreciation “ Indirect Tax + Subsidies.

Precautions :
The following precautions should be taken while estimating National Income.

• To avoid double counting take the expenditure incurred only on final goods and services.
• Government expenditure on transfer payments to be excluded like unemployment allowances, old age pension etc.
• Expenditure on second hand goods like furniture, house, land and financial assets { like shares, bonds, etc. should be excluded.
• Exclude expenditure incurred on purchase of financial assets such as shares, bonds, etc.
• Deduct indirect tax and add subsidies. Out of these methods, output method and income method are extensively used. Expenditure method is rarely used because of its practical difficulties.
