FAQs on Methods for Calculating National Income Video Lecture - Economics Class 12 - Commerce

1. How is national income calculated?
Ans. National income can be calculated using three different methods: the production approach, the income approach, and the expenditure approach. The production approach adds up all the value added at each stage of production. The income approach adds up all the incomes earned by individuals, including wages, profits, and rents. The expenditure approach adds up all the expenditures made in the economy, including consumption, investment, government spending, and net exports.
2. What is the importance of calculating national income?
Ans. Calculating national income is important as it provides a measure of the economic performance of a country. It helps in analyzing the standard of living, economic growth, and distribution of income within the country. National income data is also used by policymakers to make decisions regarding fiscal and monetary policies.
3. What are the limitations of national income calculation methods?
Ans. Some limitations of national income calculation methods include the exclusion of non-market activities, such as household work, which can lead to an underestimation of the actual economic activity. Additionally, national income calculations may not accurately capture the informal economy, leading to distortions in the data.
4. How does inflation affect national income calculations?
Ans. Inflation can impact national income calculations by distorting the real value of goods and services produced. If not adjusted for inflation, national income figures may not accurately reflect changes in the economy's output. Economists use methods like deflating nominal values to account for inflation and calculate real national income.
5. How can national income data be used to compare the economic performance of different countries?
Ans. National income data can be used to compare the economic performance of different countries by calculating metrics like GDP per capita or GDP growth rates. These indicators allow for a standardized comparison of economic output and performance across countries, providing insights into relative economic well-being and development.
