For time series data,what is unique about a time period where real GDP equal nominal GDP?

Question

Quizplus · Accepted Answer

When real GDP is equal to nominal GDP, it means that the price index used to compute the real GDP is equal to 100, which is typically the base year for the price index. This is because the real GDP is calculated by adjusting the nominal GDP for inflation using the price index. Therefore, when the price index is 100 (i.e., the base year), the real GDP is equal to nominal GDP. None of the other options mentioned in the question are unique to a time period where real GDP is equal to nominal GDP.
