In the following Table you are given information on Real GDP and Nominal GDP.
Compute the percentage change in Nominal GDP from 1970 to 1980 (15 points) and the percentage change in Real GDP (15 points) from 1970 to 1980.
Year |
Nominal GDP (In Current Prices) |
Real GDP (Base Year 2000 Prices) |
1970 |
4,000 |
2,000 |
1980 |
6,000 |
4,500 |
Where do you attribute the difference between the two percentage changes?
The percentage change in Nominal GDP from 1970 to 1980 = (Nominal GDP in 1980 - Nominal GDP in 1970) / Nominal GDP in 1970 * 100
The percentage change in Nominal GDP from 1970 to 1980 = (6000 - 4000) / 4000 * 100
The percentage change in Nominal GDP from 1970 to 1980 = 2000 / 4000 * 100
The percentage change in Nominal GDP from 1970 to 1980 = 0.5 * 100
The percentage change in Nominal GDP from 1970 to 1980 = 50%
The percentage change in Real GDP from 1970 to 1980 = (Real GDP in 1980 - Real GDP in 1970) / Real GDP in 1970 * 100
The percentage change in Real GDP from 1970 to 1980 = (4500 - 2000) / 2000 * 100
The percentage change in Real GDP from 1970 to 1980 = 1500 / 2000 * 100
The percentage change in Real GDP from 1970 to 1980 = 0.75 * 100
The percentage change in Real GDP from 1970 to 1980 = 75%
Nominal GDP is calculated by = Price in the current year * Quantity in the current year.
Real GDP is calculated by = Price in the base year * Quantity in the current year
Here, the percentage change in Real GDP from 1970 to 1980 is greater than the percentage change in Nominal GDP from 1970 to 1980 as 75% is greater than 50%. This means that price in the current year is lesser than than price in the base year and there is deflation occurring. This is what I attribute to the difference between the two percentage changes.
