Demand management—fiscal policy

· Fiscal policy = use of government spending and taxation to influence aggregate demand (AD) and achieve macroeconomic objectives.
· Use this topic with AD/AS analysis: fiscal policy mainly works by shifting AD.
· The syllabus for this subtopic includes sources of revenue, types of expenditure, expansionary vs contractionary fiscal policy, effectiveness, and HL only content on the Keynesian multiplier, crowding out, and automatic stabilizers.

Government revenue and government expenditure

· Sources of government revenue: direct taxes, indirect taxes, sale of goods and services from state-owned enterprises, sale of government assets.
· Direct taxes are taken directly from income/profits/wealth; indirect taxes are taxes on spending.
· Government expenditure includes current expenditure, capital expenditure, and transfer payments.
· Current expenditure = day-to-day spending, such as wages and running costs of public services.
· Capital expenditure = spending on long-term assets such as infrastructure, schools, hospitals, and transport networks.
· Transfer payments = payments for which no current output is produced in return, such as unemployment benefits and pensions.

Goals of fiscal policy

· Main goals: low and stable inflation, low unemployment, stable environment for long-term growth, reduced business cycle fluctuations, equitable distribution of income, and external balance.
· In exams, link fiscal policy to the specific macroeconomic problem in the question: recession/deflationary gap, inflationary gap, inequality, or external imbalance.
· Strong answers always explain both the intended goal and the possible trade-offs.

Expansionary fiscal policy

· Expansionary fiscal policy is used to close a deflationary/recessionary gap.
· It involves higher government spending, lower taxes, or both.
· These policies raise AD, so the AD curve shifts right.
· Main intended effects: higher real output, lower cyclical unemployment, and movement closer to full employment.
· In a deep recession, government spending can be especially effective because it directly injects demand into the economy.
· Possible drawback: if overused, it can create inflationary pressure, larger budget deficits, and rising government debt.

The diagram shows a rightward shift of AD from AD₀ to AD₁ to close a recessionary gap. It is ideal for revising how expansionary fiscal policy raises output toward potential GDP with only limited inflation when spare capacity exists. Source

Contractionary fiscal policy

· Contractionary fiscal policy is used to close an inflationary gap.
· It involves lower government spending, higher taxes, or both.
· These policies reduce AD, so the AD curve shifts left.
· Main intended effects: lower demand-pull inflation and less pressure on prices when the economy is overheating.
· Possible drawback: slower economic growth and higher unemployment if the policy is too strong.
· In evaluation, note that contractionary policy may improve inflation but worsen other objectives such as growth and employment.

This diagram shows a leftward shift of AD to reduce an inflationary gap. Use it to remember that contractionary fiscal policy aims to bring equilibrium output back toward potential GDP and reduce inflationary pressure. Source

AD/AS analysis and schools of thought

· The syllabus expects AD/AS diagrams showing expansionary and contractionary fiscal policy.
· For both Keynesian and monetarist/new classical views, fiscal policy works through shifts in AD, but the expected effectiveness differs.
· In a Keynesian view, fiscal policy is more powerful when there is spare capacity and a deflationary/recessionary gap.
· In a monetarist/new classical view, fiscal policy may be less effective over time because of constraints such as crowding out, debt concerns, or limited long-run impact on output.
· For exam diagrams, label clearly: AD, SRAS, LRAS/potential output, original equilibrium, new equilibrium, price level, and real output.

Effectiveness of fiscal policy

· Fiscal policy can be effective for growth, lower unemployment, and low and stable inflation, but its success depends on context.
· Strengths: can target specific sectors, and government spending may be especially effective in a deep recession.
· Constraint: political pressure — governments may choose policies for electoral reasons rather than economic efficiency.
· Constraint: time lags — recognizing the problem, passing policy, and feeling the effects all take time.
· Constraint: sustainable debt — repeated deficits may increase borrowing and create debt concerns.
· Evaluation point: effectiveness is usually greater when the economy has spare capacity and weaker when inflation is already high.

Evaluation points examiners like

· The best policy depends on the size of the output gap and whether the problem is recession or inflation.
· Government spending may have stronger effects than tax cuts when confidence is very low, because spending directly enters AD.
· Fiscal policy is usually stronger in a deep recession than when the economy is already close to full employment.
· High existing government debt can limit the size of fiscal expansion.
· In essays, always consider stakeholders: households, firms, government, taxpayers, and future generations.
· Strong evaluation compares short-run benefits with long-run costs.
