A tax reduction or spending increase is generally described as expansionary because it can raise aggregate demand, especially when households, businesses, or governments spend the added resources. A tax increase or spending reduction is generally contractionary. The size, timing, target, and economic setting matter. A temporary payment to households likely to spend it may work differently from a long-term tax provision, and infrastructure spending may take time to begin. Fiscal actions also distribute gains and burdens, even when macroeconomic stabilization is the stated purpose.

Some fiscal changes occur automatically. Progressive tax collections generally fall when incomes decline, and spending on programs such as unemployment insurance can rise as more people qualify. These automatic stabilizers support demand without Congress enacting a new response for each downturn. Discretionary fiscal policy, by contrast, requires a new legislative choice. Both affect the budget balance, but a deficit does not by itself prove that officials deliberately adopted a stimulus; recession can reduce revenue and increase benefit payments under existing law.

Suppose Congress temporarily increases infrastructure appropriations during a recession and the president signs the bill. The enactment is expansionary fiscal policy. Agencies later distributing the funds are implementing it. If the Federal Reserve changes its target range for the federal funds rate, that separate action is monetary policy. For exam questions, identify taxes or spending plus the elected branches. Do not label agency price controls, a central-bank rate decision, or private bank lending as fiscal policy merely because each affects the economy.
