Consider the concepts of nominal and real gross domestic product. Which of the following statements accurately differentiates between them?
A. Nominal gross domestic product is valued at constant base year prices, whereas real gross domestic product is valued at current market prices.
B. Nominal gross domestic product reflects changes in both physical output and price levels, whereas real gross domestic product measures changes in physical output using constant base year prices.✓ Correct Answer
C. Real gross domestic product always exceeds nominal gross domestic product during periods of inflation.
D. Nominal gross domestic product excludes indirect taxes, whereas real gross domestic product includes them.
💡 Solution & Explanation
Nominal gross domestic product is calculated using current year prices and therefore reflects both changes in physical output and changes in price levels over time. Real gross domestic product is evaluated using prices of a selected base year, isolating the actual physical change in production by eliminating the distorting effect of inflation. Comparing nominal and real values yields the gross domestic product deflator, which serves as a comprehensive indicator of economy-wide price changes. Base year revisions are periodically undertaken by national statistical agencies to reflect structural shifts.
