FAQs on Methods of Measurement of National Income and Welfare, Macroeconomics Video Lecture - Macro Economics - B Com

1. What are the different methods used to measure national income?
Ans. National income can be measured using three main methods: the income method, the expenditure method, and the output method. The income method calculates national income by summing up the incomes earned by individuals and businesses in an economy. The expenditure method calculates national income by summing up the total spending on goods and services in an economy. Finally, the output method calculates national income by summing up the value of all goods and services produced in an economy.
2. How does the income method measure national income?
Ans. The income method measures national income by summing up the incomes earned by individuals and businesses in an economy. This includes wages and salaries, profits, rent, and interest. By aggregating these different types of income, the income method provides an estimate of the total income generated in an economy during a specific period, which represents the national income.
3. What is the expenditure method for measuring national income?
Ans. The expenditure method measures national income by summing up the total spending on goods and services in an economy. It considers four main components of expenditure: consumption, investment, government spending, and net exports (exports minus imports). By adding up these different components of expenditure, the expenditure method provides an estimate of the total expenditure in an economy, which represents the national income.
4. How does the output method measure national income?
Ans. The output method measures national income by summing up the value of all goods and services produced in an economy. It calculates national income based on the value added at each stage of production. This means that the value of intermediate goods and services is not counted to avoid double-counting. By aggregating the value added across all industries and sectors, the output method provides an estimate of the total value of output in an economy, which represents the national income.
5. How are national income and welfare related?
Ans. National income and welfare are related but not synonymous. National income measures the total income generated in an economy, while welfare refers to the overall well-being of individuals within that economy. While national income can provide an indication of the economic prosperity of a country, it does not capture important factors such as income distribution, inequality, and non-monetary aspects of well-being. Therefore, while an increase in national income may suggest economic growth, it does not necessarily guarantee an improvement in overall welfare.
