Why is real GDP considered a better measure of economic growth than nominal GDP?

Real GDP is considered a better measure of economic growth than nominal GDP because it takes into account the effects of inflation. Nominal GDP measures the value of goods and services produced in an economy using current market prices, while real GDP adjusts for changes in prices over time by using a constant base year price.

One of the main reasons why real GDP is preferred is that it provides a more accurate representation of changes in the quantity of goods and services produced in an economy. Inflation causes prices to rise over time, which can lead to an increase in nominal GDP even if there has been no actual increase in production. By adjusting for inflation, real GDP allows for a more meaningful comparison of economic output across different time periods.

Another advantage of using real GDP is that it enables comparisons of economic growth between different countries or regions. Since inflation rates can vary significantly between countries, comparing nominal GDP alone may not provide an accurate picture of relative economic performance. Real GDP, on the other hand, allows for a more accurate comparison by removing the influence of differing inflation rates.

Real GDP also provides a better measure of living standards and economic well-being. By adjusting for changes in prices, real GDP reflects changes in the purchasing power of individuals and households. This is important because an increase in nominal GDP does not necessarily mean that individuals are better off if the increase is solely due to higher prices. Real GDP accounts for changes in the cost of living, allowing for a more accurate assessment of changes in economic welfare.

Furthermore, real GDP is used to calculate important economic indicators such as GDP per capita, which measures the average economic output per person in a country. This indicator is widely used to compare living standards and economic development between countries. Using nominal GDP for such comparisons would not provide an accurate reflection of the relative economic well-being of individuals.

In summary, real GDP is considered a better measure of economic growth than nominal GDP because it adjusts for the effects of inflation, allows for meaningful comparisons over time and between countries, provides a more accurate measure of living standards, and is used to calculate important economic indicators. By accounting for changes in prices, real GDP provides a more accurate representation of the quantity of goods and services produced in an economy and the economic well-being of individuals.
