Definition

• Gross Domestic Product (GDP) is the total value of all final goods and services produced within a country's borders over a specific time period, typically a year.
• It is a widely used indicator of a country's economic performance and growth.

Calculation Methods

• Expenditure Approach: GDP = Consumer Spending + Investment + Government Spending + (Exports - Imports)
• Income Approach: GDP = Compensation of Employees + Operating Surplus + Mixed Income
• Value-Added Approach: GDP = Sum of value added by all industries

Components of GDP

• Consumer Spending (C): expenditures by households on goods and services
• Investment (I): expenditures by businesses on capital goods and inventories
• Government Spending (G): expenditures by government on goods and services
• Exports (X): goods and services produced domestically but sold abroad
• Imports (M): goods and services produced abroad but sold domestically

Importance of GDP

• Economic growth: GDP growth rate indicates a country's economic growth and development
• Business cycle: GDP helps identify stages of the business cycle (recession, expansion, etc.)
• Fiscal policy: GDP is used to determine the effectiveness of government policies
• International comparison: GDP is used to compare the economic performance of different countries

Limitations of GDP

• Does not account for income inequality: GDP only measures total value, not distribution of wealth

• Does not account for environmental degradation: GDP may increase with environmental damage, despite the negative consequences.
