Answer:
d. Automatic stabilizers have a similar impact as discretionary fiscal policy but occur automatically, without action by the government. Automatic stabilizers increase aggregate demand during recessions and reduce aggregate demand during expansions.
Step-by-step explanation:
Automatic stabilizers are changes in taxes and government expenditure that occur automatically as the economy fluctuates and simulate discretionary fiscal policy.
As one example, transfer payments typically increase during recessions as more people become eligible for various programs. Aggregate demand increases as people receiving transfers increase their consumption. Discretionary fiscal policy during a recession might seek the same goal of increasing aggregate demand.
A key difference, however, is that discretionary fiscal policy requires action from government, whereas automatic stabilizers are automatic. This is significant when policy makers have trouble coming to agreement about the best course of action.
