A tax cut raises spending on both local meals and imported phones. The shift in aggregate demand is:
A. Equal to the full rise in consumption, with no import leakage
B. Smaller than the rise in total consumption, because imports do not add to demand for domestic output✓ 答案
C. A movement along AD caused by the price level
D. A leftward shift of SRAS
解說
AD includes C but subtracts M. Phones imported after the tax cut are a leakage, so demand for domestic output rises by less than total spending. The tax cut is a shift, not a movement along AD.
