Answer:
(D) a rise in unemployment
Step-by-step explanation:
A rise in unemployment is likely to follow a a decrease in aggregate demand due to a decline in consumer confidence. This is because, as aggregate demand declines, sales by businesses will fall forcing them to lay off workers, thereby resulting in a risk in unemployment.
Option A is incorrect because a decrease in aggregate demand will lead to less consumption. Option B is incorrect because an immediate adjustment back to potential GDP may not occur until monetary and fiscal policies are adjusted. Option C is incorrect because a decrease in aggregate demand resulting in lower consumption will lead to a decline in price inflation, not an increase.
