Hint:

National Income serves as a comprehensive indicator of economic health and is crucial for formulating fiscal and monetary policies.

Answer 1

National Income refers to the total monetary value of all goods and services produced within a country's borders during a specific period, usually measured annually. It is an essential indicator used to gauge the economic performance of a nation. National income encompasses all forms of income earned by the residents of a country, including wages, profits, rents, and interest. There are several methods used to calculate National Income:
1. Income Method: This method calculates National Income by summing all the incomes earned by individuals and firms in the economy, including wages, profits, rents, and interest. The formula for this approach is: \[ \text{National Income} = \text{Wages} + \text{Profits} + \text{Rents} + \text{Interest} \] 2. Expenditure Method: This approach calculates National Income by adding the total expenditure on final goods and services in an economy. The formula for this method is: \[ \text{National Income} = C + I + G + (X - M) \] Where: - \( C \) is consumption expenditure, - \( I \) is investment expenditure, - \( G \) is government expenditure, - \( X \) is exports, and - \( M \) is imports. 3. Output Method: This method calculates National Income by adding up the value of all goods and services produced in the economy. It ensures that only final goods and services are counted to avoid double-counting. National Income can also be adjusted for inflation to derive Real National Income, which measures the purchasing power of the income by considering price changes over time. Nominal National Income, on the other hand, is measured at current prices without adjusting for inflation. National Income is crucial for several reasons: - It provides an overall measure of the economic activity in a country. - It helps in assessing the standard of living, as an increase in national income typically reflects higher income levels for the population. - It serves as a basis for making policy decisions and conducting economic analysis, such as forecasting, budgeting, and investment planning. National Income can also be used to compare the economic performance of different countries and track growth over time. Additionally, it is used to analyze the distribution of income across various sectors of the economy and among different segments of the population.
