Which of the following is used for measuring national income?
Answer Details
The correct option is "Income, output and expenditure" and it is used for measuring national income.
National income is the total amount of income earned by a country's citizens and companies in a given period of time, usually a year. To measure national income, economists use the income, output, and expenditure approach, also known as the GDP (Gross Domestic Product) approach.
The income approach measures national income by adding up all the income earned by individuals and businesses in the country. This includes wages, salaries, profits, and rent.
The output approach measures national income by adding up the total value of all goods and services produced in the country during a specific period of time, usually a year.
The expenditure approach measures national income by adding up all the spending in the economy, including consumption, investment, government spending, and net exports.
By combining these three approaches, economists can accurately measure the total national income of a country, which provides valuable information about the health of the economy and its growth over time.
