Real GDP measures the value of goods and services using constant prices from a base

year. It removes the effect of inflation and shows the real change in production.

Real GDP is a better indicator of economic growth because it reflects actual increases in

output.

7. GDP Deflator

The GDP deflator is a price index used to measure the overall change in prices in the

economy. It helps convert nominal GDP into real GDP.

GDP Deflator = (Nominal GDP / Real GDP) × 100

An increase in the GDP deflator indicates inflation, while a decrease indicates deflation.

8. Importance of Measuring Aggregate Economic Activity

Measuring aggregate economic activity is important because it helps in evaluating
economic performance, comparing economic growth between countries, identifying

economic problems, supporting government policy decisions, and improving standards

of living.

9. Limitations of GDP

Despite its importance, GDP has several limitations. It does not measure income

distribution, ignores unpaid work, does not reflect environmental damage, and does not

fully capture quality of life. Therefore, GDP should be used together with other
indicators.

10. Other Indicators of Economic Activity

In addition to GDP, economists use other indicators such as Gross National Product

(GNP), GDP per capita, economic growth rate, and employment and unemployment

rates.
