Nominal GDP rises 8% and the price level rises 5%. A fair first reading is that:
A. Real output rose by 8%.
B. Real output fell by 5%.
C. Real output rose, but by less than 8%, because part of the rise is prices.✓ 答案
D. Nominal GDP does not include prices, so real GDP also rose 8%.
解說
Nominal GDP values output at current prices, so it mixes quantities and prices. If prices rise 5% while nominal GDP rises 8%, real GDP rises by roughly the difference, not by the full 8% and not by a fall of 5%.
