GDP and Economic Growth
Gross Domestic Product (GDP)
GDP is the total market value of all final goods and services produced in a country during a specific period (usually one year).
GDP Components
\[GDP = C + I + G + (X - M)\]
Where: - C = Consumption (Household spending) - I = Investment (Business investment) - G = Government Spending - X = Exports - M = Imports - (X - M) = Net Exports
Types of GDP
1. Nominal GDP
GDP measured at current prices.
2. Real GDP
GDP measured at constant prices to eliminate the effect of inflation.
\[\text{Real GDP} = \frac{\text{Nominal GDP}}{\text{GDP Deflator}} \times 100\]
Economic Growth Rate
\[\text{Growth Rate} = \frac{\text{GDP}_{\text{this year}} - \text{GDP}_{\text{last year}}}{\text{GDP}_{\text{last year}}} \times 100\%\]
GDP per Capita
\[\text{GDP per Capita} = \frac{\text{GDP}}{\text{Population}}\]
Measures the average standard of living of a country’s residents.

- Doesn’t measure welfare - Doesn’t account for income distribution
- Ignores informal economy - Excludes barter transactions, household economy
- Doesn’t consider quality of life - Health, education, environment
- Negative externalities - Pollution and environmental damage are not subtracted
