What is Fiscal Policy?
Fiscal policy refers to government decisions about taxes and spending to influence the economy. By adjusting these tools, governments aim to manage inflation, reduce unemployment, and promote sustainable economic growth.
Fiscal policy is the use of government taxes and spending to influence aggregate demand and economic growth. Expansionary fiscal policy increases spending or cuts taxes; contractionary policy does the opposite.

Step-by-step worked examples
Government increases spending on infrastructure by $100B. If the multiplier is 2, what is the total GDP effect?
ΔG = $100B (spending increase) Multiplier = 2 Total impact = ΔG × Multiplier = $100B × 2 = $200B GDP increases by $200B
During a recession with 8% unemployment, should fiscal policy be expansionary or contractionary?
Recession → need to boost AD and employment Expansionary fiscal policy Increase G or cut T (taxes) AD shifts right, output and employment rise
The government cuts taxes by $50B. If the tax multiplier is 1.5, what is the GDP impact?
ΔT = −$50B (tax cut) Tax multiplier = 1.5 Total GDP effect = ΔT × Tax Multiplier = −$50B × 1.5 = −$75B But the sign: lower taxes increase income, so GDP ↑ $75B

Common mistakes
Fiscal policy and monetary policy are the same. — Correct: Fiscal uses taxes/spending (government); monetary uses interest rates/money supply (central bank).
The fiscal multiplier is always negative. — Correct: It's positive — spending boosts output; the ratio of the boost to initial change is the multiplier.
Expansionary fiscal policy has no downsides. — Correct: It can cause inflation, crowd out private investment, and increase government debt.
Fiscal multipliers are constant across all economies. — Correct: They vary by country, economic conditions, and openness to trade.
FAQ
What is fiscal policy?
Government decisions about taxes and spending designed to influence aggregate demand and achieve economic goals like growth and employment.
How does fiscal policy affect the economy?
Changes in G (spending) or T (taxes) shift AD. Higher G or lower T boost AD; lower G or higher T reduce AD.
What is the fiscal multiplier?
The ratio of total GDP change to initial spending or tax change. E.g., multiplier of 2 means $1 in spending creates $2 GDP increase.
Is fiscal policy more effective in recessions or booms?
Typically more effective in recessions when AD is weak; in booms, it may cause inflation and crowd out private investment.
