Topic 5: Fiscal and Supply Side Policies

5.1 Fiscal Policy

  • Definition: Fiscal policy involves the manipulation of government spending, taxation, and the budget balance. It serves both macroeconomic and microeconomic functions.

  • Instruments:

    • Government Spending and Taxation: Governments can adjust these to stimulate the economy, influencing the circular flow by altering the budget, and targeting spending and taxes in specific areas.
    • Aims: Stimulate economic growth and stabilize the economy.
  • UK Context:

    • Major expenditures: Pensions, welfare benefits, health, and education.
    • Major revenue: Income tax.

Influence on Aggregate Demand (AD)

  • Expansionary Fiscal Policy: Increases AD by increasing spending or decreasing taxes, often worsening the budget deficit and increasing government borrowing.

  • Deflationary Fiscal Policy: Decreases AD by cutting spending or raising taxes, improving the budget deficit.

Influence on Aggregate Supply (AS)

  • Tax Reductions: Lower income and corporation taxes encourage spending and investment.
  • Subsidies and Education Spending: Supports firm cost reduction and improved productivity through better training and healthcare.
  • Infrastructure Investment: Spending on roads and schools enhances infrastructure.

Government Budget

  • Budget Deficit: Expenditure exceeds tax receipts.
  • Budget Surplus: Tax receipts exceed expenditure.
  • Debt vs. Deficit: Debt is accumulated deficits; deficit/surplus is the annual difference.

Taxes

  • Direct Taxes: Imposed on income, paid directly (e.g., income tax, corporation tax).

  • Indirect Taxes: Imposed on goods/services, raising production costs (e.g., VAT, fuel duty).

  • Types of Taxes:

    • Proportional: Fixed rate for all (flat tax).
    • Progressive: Higher income pays higher rates (e.g., UK income tax).
    • Regressive: Lower income pays higher proportion (e.g., Congestion Charge).

Principles of Taxation

  • Criteria developed by Adam Smith, including:

    1. Low collection cost relative to yield.
    2. Clear timing and quantity.
    3. Convenient payment methods.
    4. Based on ability to pay.
  • Modern additions include efficiency, compatibility, and inflation adjustments.

Limitations of Fiscal Policy

  • Imperfect Information: Can lead to inefficient spending.
  • Time Lag: Effects may take months or years.
  • Crowding Out: Private sector funds reduced when government borrows.
  • Interest Rates: High rates can reduce effectiveness.
  • Debt: Excessive spending leads to repayment difficulties.

Public Expenditure and Taxation

  • Types:

    • Current Expenditure: Recurring (e.g., drugs for health service).
    • Capital Expenditure: On assets (e.g., roads, schools).
    • Transfer Payments: Welfare payments without exchange of goods/services (e.g., pensions).
  • Global Context:

    • Major UK expenditures: Pensions, welfare, health, education.
    • Education spending is constant; defense spending is decreasing.

Public Expenditure Impacts

  • Productivity and Growth: Investments in human capital boost growth.
  • Crowding Out: Government borrowing limits private sector investments.
  • Taxation Levels: High government debt might lead to increased taxes.
  • Equality and Living Standards: Progressive taxes and redistributive policies reduce inequality.

Budget Balance and National Debt

  • Definitions:

    • Balanced Budget: Expenditure equals revenue.
    • National Debt: Accumulated government deficit over time.
  • Cyclical vs. Structural Deficits:

    • Cyclical: Temporary, linked to business cycles.
    • Structural: Persistent imbalance.

Consequences of Budget Deficits

  • Inflation: Increased AD can be inflationary.
  • Interest Rates: May rise due to increased government borrowing.

National Debt Significance

  • Borrowing Costs: Increase with rising demand for credit.
  • Interest Rates and Confidence: Loss of confidence can necessitate higher interest rates.

Office for Budget Responsibility (OBR)

  • Role: Analyzes UK finances, produces forecasts, judges fiscal targets, scrutinizes spending, and assesses long-term fiscal sustainability.
