Demand-pull inflation, in an AD–SRAS diagram, is shown by:
A. AD shifting right along a given SRAS✓ 答案
B. SRAS shifting left
C. A fall in the price level with rising real output
D. The demand curve for one brand of noodles becoming steeper
解說
Demand-pull is extra aggregate spending: AD shifts right and both the price level and real output rise along the existing SRAS. A leftward SRAS shift is cost-push. A single-good diagram is not the price level.
