3. Gross Domestic Product (GDP)

Gross Domestic Product (GDP) is the main indicator used to measure aggregate

economic activity. GDP represents the total market value of all final goods and

services produced within the borders of a country during a specific period of time.

GDP includes production by both domestic and foreign firms operating inside the

country. What matters is the location of production, not the nationality of the
producer.

4. Key Components of GDP Definition

The definition of GDP contains several important elements that must be clearly

understood.

Market Value: GDP is measured using prices to combine different goods and services

into a single value.

Final Goods and Services: Only final goods are counted to avoid double counting.
Produced Within the Country: Only production inside national borders is included.

Specific Time Period: GDP is measured annually or quarterly.

5. Methods of Measuring GDP

There are three main methods used to calculate GDP. Each method looks at the

economy from a different perspective, but all should result in the same total value.

5.1 Expenditure Approach

The expenditure approach calculates GDP by adding total spending on final goods and

services in the economy.

GDP = C + I + G + (X − M)
