3.6 Demand management - fiscal policy

Fiscal policy changes government spending, taxation and transfers to influence demand, output, employment, distribution and debt.

The budget affects aggregate demand directly and incentives indirectly; financing and implementation determine the net effect.

Name the instrument, target and likely transmission.

Higher public investment can raise demand now and productive capacity later.

A budget deficit is a flow in a period; debt is the accumulated stock.

Government revenue includes direct taxes, indirect taxes, sales of goods and services by state-owned enterprises, and proceeds from selling government assets. Expenditure includes current spending on recurring operations and wages, capital spending on long-lived assets such as infrastructure, and transfer payments that redistribute income without buying current output. Classify the item before predicting AD, capacity, equity or budget effects: an asset sale is revenue but not recurring tax income, while a transfer supports household income but is not direct government purchase of output.

Fiscal policy may pursue growth, employment, price stability, equity, external balance and sustainability.

Goals can conflict across time and groups; a policy should state its priority and constraint.

Identify objective, time horizon and affected stakeholders.

A transfer may reduce poverty but increase spending unless financed elsewhere.

There is no single “good” fiscal stance without context.

Expansionary fiscal policy raises spending or cuts net taxes to support demand; contractionary policy does the reverse to reduce demand or debt pressure.

The effect depends on multiplier, interest rates, imports, confidence and spare capacity.

Match policy direction to the macro problem and state a trade-off.

During a recession, temporary infrastructure spending may raise output; near full capacity it may add inflation.

Policy direction does not guarantee the intended outcome.

Expansionary fiscal policy raises government spending or lowers taxes, shifting AD right to close a recessionary gap; contractionary policy lowers spending or raises taxes, shifting AD left to close an inflationary gap. In the monetarist/new-classical diagram, compare equilibrium with vertical LRAS at potential output. In the Keynesian diagram, the output-price mix depends on whether equilibrium lies on the flat, upward-sloping or vertical AS section. Label the initial gap, policy-induced AD shift and new equilibrium rather than assuming identical effects in both models.

Fiscal policy effectiveness depends on timing, multiplier, implementation capacity, financing, confidence, exchange rates and the state of the economy.

Long lags or supply constraints can weaken a well-designed policy; targeted spending may work better than broad demand stimulus.

Identify the binding constraint and evidence before judging.

A stimulus arrives after a downturn has ended, so it may intensify inflation rather than stabilise output.

A policy can be appropriate yet ineffective.

Constraints include political pressure over taxes and spending, recognition/decision/implementation time lags, sustainable-debt limits and—at HL—crowding out. Strengths include targeting particular sectors or groups and the potency of direct government spending in a deep recession when private demand is weak. Evaluate growth, unemployment and price stability separately: stimulus is likelier to raise real output with spare capacity and a large multiplier, but near capacity, with import leakages or delayed delivery, it may mainly raise prices or debt.
