Government and the Macroeconomy

Welcome to Unit 4 of IGCSE Economics! In the next 8 bitesized sections, we will review the different aspects that connect the Government to the Macroeconomy.

Make sure to pay attention, because at the end we have a quiz to help you understand your level of preparedness for this topic!

4.1 The Role of Government

Local Government Role

• Collects taxes to fund local services
• Provides: rubbish collection, street lighting, local infrastructure

National Government Role

• Makes decisions to achieve macroeconomic aims
• Uses three main policy tools:

1. Fiscal Policy: Decisions on taxation and government spending
2. Monetary Policy: Central bank decisions on interest rates, money supply, and exchange rates
3. Supply-side Policies: Measures to increase availability/affordability of goods and services

4.2 Macroeconomic Aims of Government

Key Government Objectives:

1. Economic Growth - Increase in real GDP over time
2. Full Employment - Low unemployment rates
3. Price Stability - Low, stable inflation
4. Balance of Payments Stability - Balanced international trade
5. Income Redistribution - Reducing inequality

Important Definitions:

Economic Growth: Long-term expansion in productive capacity (PPC shifts right)

Unemployment: When people are willing, able, and actively seeking work but cannot find employment

• Formula: (Unemployed People ÷ Labour Force) × 100

Inflation: Sustained increase in general price level

• Demand-Pull Inflation: Caused by demand exceeding supply
• Cost-Push Inflation: Caused by rising costs of factors of production

Balance of Payments: Financial record of a country's transactions with the rest of the world

The Economic Equation:

GDP = C + I + G + (X - M)

• C = Consumer Expenditure
• I = Investment Expenditure
• G = Government Expenditure
• X = Exports
• M = Imports

Conflicts Between Macroeconomic Aims

Governments face trade-offs when pursuing different objectives:

1. Employment vs. Prices: Higher employment → Higher consumer spending → Demand-pull inflation
2. Growth vs. Balance of Payments: Economic growth → Higher imports → Trade deficit
3. Employment vs. Balance of Payments: More employment → Higher disposable income → More imports
4. Growth vs. Price Stability: Lower interest rates stimulate growth but may cause inflation

4.3 Fiscal Policy

Government Budget

The government's financial plan showing planned revenues and expenditures from sources like:

• Taxation
• Privatization
• Government bonds

Types of Taxes

By Payment Method:

• Direct Taxes: Paid directly on income (income tax, corporation tax)
  • Help redistribute income and reduce inequality
• Indirect Taxes: Paid on goods/services (VAT, excise duties)
  • Increase production costs, often used on demerit goods
• Tariffs: Import taxes to reduce imports and improve balance of payments

By Tax Rate Structure:

• Progressive: Higher income → Higher tax rate
• Regressive: Higher income → Lower effective tax rate
• Proportional: Same percentage regardless of income (e.g., VAT)

Principles of Good Taxation (3E, 2C, F):

• Equitable: Fair distribution of tax burden
• Economical: Low cost to collect
• Efficient: Doesn't distort economic behavior
• Convenient: Easy to pay
• Certain: Clear and predictable
• Flexible: Can be adjusted as needed

Effects of Taxation

On Prices & Quantity: Higher taxes → Higher prices, Lower quantity (due to increased costs)

On Economic Growth: May reduce incentives to work and invest

On Inflation: Higher taxes can reduce consumer spending, easing inflation

Tax Avoidance vs. Tax Evasion:

• Tax Avoidance: Legal minimization of tax payments
• Tax Evasion: Illegal non-payment or under-declaration of taxes

Fiscal Policy Types

Expansionary Fiscal Policy: Lower taxes + Higher government spending

• Stimulates economic growth
• Increases employment
• May worsen balance of payments
• Reduces income redistribution

Contractionary Fiscal Policy: Higher taxes + Lower government spending

• Reduces inflation
• May slow economic growth
• Improves government budget position

4.4 Monetary Policy

Key Concepts

Money Supply: Total amount of money in the economy at a given time

Monetary Policy: Use of interest rates, exchange rates, and money supply to control macroeconomic objectives

Policy Types

Expansionary Monetary Policy: Lower interest rates → Increase money supply → Higher disposable income → Higher GDP

Contractionary Monetary Policy: Higher interest rates → Decrease money supply → Lower spending → Control inflation

Tools of Monetary Policy

Repo Rates: Amount banks must keep as reserves (affects money supply available for loans)

Interest Rate Changes:

• Lower rates encourage borrowing and spending
• Higher rates encourage saving and reduce spending

Effects on Economic Variables

↑C + ↑I + ↑G + ↑GDP → ↑AD → ↑AS → PPC shifts outward

Limitations

• Time Lag: Takes time for effects to show
• Other Factors: Business confidence, external shocks can interfere

4.5 Supply-Side Policies

Definition

Long-term measures to increase productive capacity, leading to outward PPC shift

Policy Measures

Human Capital Development:

• Education and training programs
• Skills development initiatives

Labor Market Reforms:

• Reducing trade union power
• Reforming unemployment benefits
• Adjusting minimum wage policies

Business Environment:

• Lower direct taxes
• Deregulation
• Privatization
• Investment incentives

Effects of Supply-Side Policies

• Increase GDP without causing inflation
• Improve employment through better skills
• Shift PPC outward
• Increase productivity and national output
• Improve export competitiveness
• Enhance future disposable income through better education

4.6 Economic Growth

Types of GDP Measurement

Nominal GDP: Monetary value of goods and services (not adjusted for inflation)

Real GDP: GDP adjusted for inflation (shows true economic growth)

GDP Per Capita: GDP divided by population size (shows average living standards)

Components of GDP

• Consumption: Household spending
• Investment: Business capital spending to increase production
• Government Spending: Public investment in infrastructure
• Net Exports: Export earnings minus import expenditure

Business Cycle

Fluctuations in economic activity over time, showing long-term growth trend with periods of expansion and contraction.

Recession

Fall in GDP for two consecutive quarters, characterized by:

• Declining national output
• Business bankruptcies
• Rising unemployment and underemployment
• Falling exports and imports
• Reduced investment
• Possible deflation
• Increased government spending on benefits
• Higher youth unemployment

4.7 Employment & Unemployment

Key Definitions

Employment: Economic use of labor as a factor of production

Full Employment: Everyone willing and able to work has a job

Unemployment Rate: (Number Employed/Workforce) × 100

Employment Patterns

• Delayed workforce entry (longer education)
• Aging population
• Increasing female participation rates
• Growth in formal sector employment

Measurement Methods

• Claimant Count: Number claiming unemployment benefits
• Labour Force Survey: ILO standardized household survey

Types of Unemployment

Frictional Unemployment: Time delay between leaving one job and starting another

Structural Unemployment: Permanent decline in demand for certain products/skills (often due to foreign competition)

Cyclical Unemployment: Caused by lack of demand during economic downturns

4.8 Inflation & Deflation

Inflation

Definition: Sustained increase in general price level over time

Hyperinflation: Very high, uncontrolled inflation rates

Consumer Price Index (CPI): Weighted index measuring cost of living for average household

Causes of Inflation

Cost-Push Inflation: Higher production costs drive up prices

Demand-Pull Inflation: Higher aggregate demand drives up prices

Imported Inflation: Higher import costs increase domestic prices

Effects of Inflation

Negative Effects:

• Menu Costs: Frequent price changes
• Reduced purchasing power for consumers
• Shoe Leather Costs: Time spent searching for best deals
• Losses for savers and lenders
• Harm to fixed-income earners and the poorest
• Reduced export competitiveness

Positive Effects:

• Benefits borrowers (pay back with cheaper money)
• May indicate economic growth

Deflation

Definition: Sustained fall in general price level

Benign Deflation: Not threatening to economy Malign Deflation: Harmful to economic growth

Effects of Deflation

• Increased unemployment
• Business bankruptcies
• Wealth effects (falling asset values)
• Debt burden increases
• Reduced consumer spending (waiting for lower prices)
