Key Points
Definition of National Income.
National income is the total money earned by a nation’s people and businesses. It includes wages, profits, rents, and interests.
Core methods to calculate National Income.
Three methods: Product Method (value added), Expenditure Method (total spending), and Income Method (total incomes earned).
Product Method overview.
Calculates National Income based on the total value added at each stage of production, avoiding double counting of intermediate goods.
Expenditure Method explanation.
Total expenditure made on final goods and services. GDP = C + I + G + (X - M) describes this method.
Income Method highlights.
Measures total income earned by factors of production: National Income (NI) = Wages + Interest + Profits + Rent.
Final Goods vs. Intermediate Goods.
Final goods are ready for consumption while intermediate goods are used in production. Only final goods count in GDP.
Concept of Depreciation.
Depreciation is the reduction in value of capital assets over time. It is deducted to find net investment.
Gross vs. Net Investment.
Gross Investment includes total spending on capital, while Net Investment is Gross minus Depreciation.
Circular Flow of Income.
Describes how households provide factors of production to firms in exchange for income, which is then spent on goods.
GDP definition.
Gross Domestic Product is the total value of all final goods and services produced within a country’s borders in a year.
GNP vs. GDP.
Gross National Product includes earnings by residents from abroad and excludes earnings by non-residents in the country.
Real GDP vs. Nominal GDP.
Real GDP is adjusted for inflation and reflects the true growth of an economy. Nominal GDP is current prices without adjustment.
Consumer Price Index (CPI).
Measures the average change over time in prices paid by consumers for a basket of goods and services, reflecting inflation.
Wholesale Price Index (WPI).
Tracks the changes in price of goods sold and traded in bulk between businesses, prior to retail pricing.
GDP Deflator importance.
Measures the ratio of nominal GDP to real GDP, helping to assess the level of price changes in the economy.
Limitations of GDP as a welfare measure.
GDP does not account for income distribution, non-monetary transactions, or externalities, impacting its welfare relevance.
Factors impacting GDP.
Production, consumption, investment, and net exports directly affect GDP levels, showing the economy's health.
National Income identity.
NI can be calculated as aggregate output minus depreciation and indirect taxes plus subsidies, giving a holistic economic view.
Role of Government in GDP calculation.
Government spending influences GDP through public investments, salaries, and consumption expenditures on services.
Distinction between Personal Income and Disposable Income.
Personal Income is total earnings before taxes, while Disposable Income is what households can spend or save after taxes.
