What Is It?
Fiscal policy refers to government decisions on taxation and spending to influence economic activity. Expansionary policy (lower taxes, higher spending) stimulates growth; contractionary policy (higher taxes, lower spending) cools overheating.
Origin
Modern fiscal policy emerged from Keynesian economics in the 1930s, advocating countercyclical government intervention. Automatic stabilizers (unemployment benefits, progressive taxes) were supplemented by discretionary stimulus packages.
Why It Matters
Fiscal policy directly affects aggregate demand, employment, and growth. It provides tools when monetary policy reaches limits (zero lower bound). However, political constraints, implementation lags, and debt sustainability limit its effectiveness.

Market Mechanics
Fiscal multipliers measure GDP impact per dollar of stimulus (typically 0.5-2.0 depending on conditions). Ricardian equivalence suggests taxpayers save stimulus anticipating future taxes. Crowding out occurs when government borrowing raises rates and displaces private investment.
How It Behaves
Fiscal policy has implementation lags (recognition, decision, implementation) but direct demand impact. Automatic stabilizers respond immediately to downturns. Discretionary stimulus arrives after recessions begin. Debt constraints emerge when deficits persist.

Key Takeaways
Fiscal policy is a powerful but constrained tool. Understanding multipliers, lags, Ricardian effects, and debt sustainability enables better assessment of fiscal initiatives and their market impacts.
