Fiscal policy is the use of government spending and taxation to influence aggregate demand (AD) and achieve macroeconomic objectives such as growth, low unemployment, and price stability.

Government Budget

Meaning

  • A government budget shows:
    • Revenue (mainly from taxes)
    • Expenditure (government spending)

Budget Positions

  • Budget Deficit:
    • Government spending > revenue
  • Budget Surplus:
    • Government revenue > spending

Analysis

  • Budget deficit
    → government injects more into economy than it withdraws
    → AD increases
    → higher output and employment (in recession)
  • Budget surplus
    → government withdraws more than it injects
    → AD decreases
    → helps reduce inflation

National Debt

Meaning

  • The total accumulated government borrowing over time

Significance (with analysis)

  • High national debt
    → higher interest payments
    → less government spending on public services
    → potential need for higher taxes
  • However:
  • Borrowing for investment
    → improves infrastructure
    → increases productivity
    → shifts LRAS right
    → supports long-term growth

Taxation

Types of Taxes

Direct Taxes

  • Paid on income/wealth (e.g. income tax)

Indirect Taxes

  • Paid on goods/services (e.g. VAT)

Analysis

  • Increase in direct taxes
    → reduces disposable income
    → consumption falls
    → AD decreases
  • Increase in indirect taxes
    → increases cost of goods
    → reduces real income
    → consumption falls
    → AD decreases

Tax Structures

  • Progressive: Higher income → higher % tax
  • Regressive: Lower income → higher % burden
  • Proportional: Same % for all

Rates of Tax

  • Marginal Rate of Tax (MRT):
    • Tax on next unit of income
  • Average Rate of Tax (ART): ART=Total taxTotal income×100ART = \frac{\text{Total tax}}{\text{Total income}} \times 100

Reasons for Taxation

  • Raise revenue
    → fund public goods and services
  • Redistribute income
    → reduce inequality
  • Correct market failure
    → e.g. taxes on demerit goods
    → reduce consumption
    → improve welfare
  • Manage AD
    → influence economic activity

Government Spending

Types of Spending

  • Current Spending:
    • Wages, benefits, day-to-day expenses
  • Capital Spending (Investment):
    • Infrastructure, education, healthcare

Reasons for Government Spending

  • Provide public goods
    → private sector underprovides
    → government ensures provision
  • Correct market failure
    → improves resource allocation
  • Stimulate economic activity
    → increase AD
    → raise output and employment
  • Promote long-term growth
    → investment in infrastructure
    → increases productivity
    → shifts LRAS right

Types of Fiscal Policy

Expansionary Fiscal Policy

  • Increase spending and/or reduce taxes

Analysis

  • ↑ government spending or ↓ taxes
    → ↑ disposable income
    → ↑ consumption and investment
    → AD increases
    → ↑ real output and employment
    → possible inflationary pressure

Contractionary Fiscal Policy

  • Reduce spending and/or increase taxes

Analysis

  • ↓ government spending or ↑ taxes
    → ↓ disposable income
    → ↓ consumption and investment
    → AD decreases
    → ↓ inflation
    → possible fall in output and employment

Impact on Macroeconomic Variables

Real Output (GDP)

  • Expansionary policy
    → AD rises
    → firms increase production
    → GDP increases
  • Contractionary policy
    → AD falls
    → production decreases
    → GDP falls

Employment

  • Expansionary policy
    → higher demand for goods
    → firms hire more workers
    → unemployment falls
  • Contractionary policy
    → lower demand
    → firms reduce workforce
    → unemployment rises

Price Level

  • Expansionary policy
    → demand-pull inflation may occur
  • Contractionary policy
    → reduces inflationary pressure

Evaluation

Strengths

  • Direct impact on AD
    → effective in recession
  • Can target specific sectors
    → improves efficiency

Limitations

Time Lags

  • Policy decisions take time
    → delayed impact on AD

Crowding Out

  • Increased government borrowing
    → higher interest rates
    → reduces private investment
    → limits effectiveness of policy

Inflation Risk

  • Excessive expansionary policy
    → AD exceeds AS
    → demand-pull inflation

Political Constraints

  • Governments may avoid:
    • Raising taxes
    • Cutting spending
      → limits policy effectiveness

Short Run vs Long Run

  • Short run:
    • Affects AD strongly
  • Long run:
    • Capital spending
      → increases productive capacity
      → supports sustainable growth

Final Summary

  • Fiscal policy = taxation + government spending
  • Budget:
    • Deficit → stimulates AD
    • Surplus → reduces AD
  • National debt = accumulated borrowing
  • Taxes affect disposable income and AD
  • Spending affects AD and long-term growth
  • Expansionary → ↑ AD → ↑ output, employment, inflation
  • Contractionary → ↓ AD → ↓ inflation, output, employment
