01 What is the basic formula for the GDP deflator?
Answer and explanation
Correct answer: A. (Nominal GDP ÷ Real GDP) × 100
Explanation: The GDP deflator measures the overall price level of domestically produced final goods and services relative to the base year. Its formula is GDP deflator = (nominal GDP ÷ real GDP) × 100. Nominal GDP uses current prices, whereas real GDP uses base-year prices. A value of 100 represents the base-year price level; a higher value indicates higher prices than in the base year.
