Using a graph, differentiate between a nominal GDP and a real GDP, and explain what you do with

concrete examples

A nominal GDP and a real GDP are two different measures of the economic output of a country. A graph can help visualize the difference between these two concepts.

A nominal GDP refers to the total value of goods and services produced in a country over a specific time period, usually a year, when measured at current market prices. It represents the actual dollar value of the final goods and services produced in an economy. Nominal GDP includes all price changes that occur over time, including inflation or deflation. Therefore, it does not account for changes in the purchasing power of the currency.

On the other hand, a real GDP adjusts for the effects of inflation or deflation and calculates the total value of goods and services produced within an economy, based on constant prices from a base year. Real GDP measures the actual physical output of goods and services, independent of any price changes.

Let's consider an example to differentiate between these two concepts using a graph:

Graph Example:
The X-axis represents different years, while the Y-axis shows the GDP value ($).

Year: 2018 2019 2020 2021
Nominal GDP: $2,000 $2,300 $2,500 $2,700
Real GDP: $2,000 $2,100 $2,200 $2,290

In this example, we can observe that the nominal GDP is increasing from 2018 to 2021, reflecting the actual value of goods and services produced each year without adjusting for inflation. However, the real GDP takes into account the inflationary effects and shows a different growth pattern.

Using the example, if the inflation rate between 2018 and 2021 was 5% per year, we can see that the real GDP reflects a smaller increase compared to nominal GDP. The real GDP adjusts the values based on a constant price level (base year) to eliminate the effect of inflation, allowing us to assess the actual physical output of the economy. Therefore, in this example, the real GDP demonstrates a more accurate measure of economic growth, as it adjusts for changes in prices.

In summary, a graph can help illustrate the difference between nominal GDP and real GDP by displaying their respective values over time. Nominal GDP reflects the current dollar value of goods and services, while real GDP adjusts for inflation or deflation, providing a more accurate measure of economic output.
