01 Why can comparison of national income at constant prices be more reliable in macroeconomics?
Answer and explanation
Correct answer: A. It removes the effect of price changes and shows changes in real output
Explanation: Current-price national income can rise merely because prices have increased. Valuing output at constant prices holds the price base fixed and therefore gives a better indication of the change in the actual quantity of goods and services produced. It makes comparisons across years more meaningful.
