National Income

Introduction to National Income

The sum of income a country’s people receive from factors supplied to production units both within and outside the country’s geographical limits is referred to as the country’s national income.

Definition of National Income

The term “national” means “of residents,” and the term income means ‘factor income.’

Only the money earned by inhabitants is taken into account when calculating national income, regardless of their economic territory. It could be within or outside the economic territory, which means we need to figure out if the money comes from residents or non-residents. The income is included in the national income if it is a resident, but it is omitted from the national income Account if it is a non-resident.

Factor Income

• The earnings earned by persons who provide factor services to manufacturing units are considered factor incomes. The four components of production are land (natural resources), labor (human resources), capital (man-made resources) and entrepreneurship.
• A manufacturing unit uses these factors of production to produce goods and services. Factor payment is a payment made to a factor of production for services done. Landowners receive rent, and workers receive wages or salaries, capital receive interest, and the entrepreneur profits.
• The national income of a country is the sum total of these factor incomes derived by its citizens.

Important Tools for Measuring National Income 

Gross Domestic Product (GDP)

• GDP is the total value of all final goods (items intended for final use) and services generated in a country’s domestic territory during a fiscal year.
• It only includes purchases of newly manufactured products and services, not the sale or resale of used goods (but services provided in reselling are included in GDP).
• GDP is used to calculate an economy’s growth rate. The 6 percent growth rate indicates that the economy has grown by 6% over the previous year.

Net Domestic Product (NDP)

• The annual measure of a country’s economic production, adjusted for depreciation, is known as the NNP(Net Domestic Product )
• It is an important indication of a country’s economic development. When compared to GDP, NDP accounts for the depreciation of the country’s capital assets, such as homes, vehicles, and machinery. It represents the amount of money spent by a country to sustain its existing level of economic productivity over a given time period.
• NDP accounts for accounting depreciation and other causes of value loss, such as obsolescence and destruction.

Gross National Product (GNP)

• The monetary worth of all final goods and services created by ordinary residents of the country in a financial year, regardless of production location, is referred to as GNP.
• The criterion for identifying nationality in GNP calculations is residence rather than citizenship, as long as residents spend their money within the country.
• According to international accounting standards, residents are those who have lived in the country for a year or more. Non-residents, on the other hand, are people who have spent the previous year or more outside the country.

Net National Product

Net National Product (NNP) is defined as Gross National Product (GNP) minus depreciation.

Calculation Methods for National Income

Product Method

• Also known as the value-added method, output method, or product method, the Product Method’s principal purpose is to calculate national income by considering the value added to a product at various manufacturing stages.
• The national income in economics is calculated using this approach by summing the value-added of each firm in each of the three sectors (Primary, Secondary, and Tertiary).
• Because this method focuses on net value added by each component in the manufacturing process, elements like net indirect taxes, raw material consumption, capital creation, and so on should be removed or deducted from the enterprise’s output.
• Interest, profit, earnings, salaries, and other sources of income

Expenditure Method

• This technique adds up all family, government, and corporate expenditures on consumer goods and investment created within the domestic area to arrive at a total. NI.
• GDP equals C + I + G + (X-M), with C denoting private final consumption expenditure. G stands for final consumption expenditures by the government. I = Final Goods Expenditure [Investment or Capital Formation] X stands for exports. Imports = M,(X-M ) stands for net exports.

National Income Accounting’s (NIA) Importance

• NIA provides a mathematical foundation for determining and evaluating economic policies, and quantitative macroeconomic modeling and analysis.
• It aids in assessing a country’s economic performance.
• It aids in the comparison of living standards.
• It also aids in assessing a country’s per-capita income.

Conclusion

This topic provides complete knowledge about National Income and how to compute revenue expenditure and product has been conducted in a financial period of time, and has a need for national income accounts. National income is computing the monetary evaluation of the circulation of goods and services generated within a financial period of time. The rate of growth and level of national income is a necessity for economists ,businessmen and the government. In this we also learn the  importance of National Income and how it is calculated and its relation with Net National Product (NNP).
