MACROECONOMICS – UNEMPLOYMENT, INFLATION & ECONOMIC GROWTH ANALYSIS CHAINS

This is one of the MOST TESTED Paper 4 areas.

Examiners constantly combine:

• unemployment

• inflation

• growth

• living standards

• policy conflicts

• productivity

• development

Most macro essays eventually come back to these three objectives.

CYCLICAL UNEMPLOYMENT CHAIN

• Aggregate demand falls

• Firms reduce output

• Labour demand decreases

• Workers laid off

• Unemployment rises

• Household incomes fall

• Consumption decreases

• AD falls further

• Recession worsens

Evaluation:

• automatic stabilisers reduce impact

• expansionary policy may solve issue

• depends on confidence

STRUCTURAL UNEMPLOYMENT CHAIN

• Industry structure changes

• Worker skills become outdated

• Labour demand falls in sector

• Long-term unemployment rises

• Occupational immobility worsens issue

Evaluation:

• retraining programs may reduce unemployment

• labour mobility important

• technology increases structural change

FRICTIONAL UNEMPLOYMENT CHAIN

• Workers changing jobs temporarily

• Short-term unemployment occurs

• Labour market adjusts

• Workers eventually re-employed

Evaluation:

• often unavoidable

• may indicate dynamic labour market

SEASONAL UNEMPLOYMENT CHAIN

• Demand changes during year

• Firms reduce workers temporarily

• Seasonal unemployment rises

Examples:

• tourism

• agriculture

Evaluation:

• predictable

• workers may diversify skills

TECHNOLOGICAL UNEMPLOYMENT CHAIN

• Automation increases

• Machines replace workers

• Labour demand falls

• Structural unemployment rises

Evaluation:

• new industries/jobs may develop

• productivity gains may outweigh losses long-run

DEMAND-PULL INFLATION CHAIN

• Aggregate demand rises rapidly

• Excess demand develops

• Firms raise prices

• Inflation rises

• Purchasing power falls

Evaluation:

• depends on spare capacity

• economic growth may rise simultaneously

COST-PUSH INFLATION CHAIN

• Production costs rise

• SRAS shifts left

• Prices rise

• Output falls

• Inflation and unemployment rise together

Evaluation:

• temporary supply shocks may reverse

• subsidies may reduce impact

WAGE-PUSH INFLATION CHAIN

• Workers demand higher wages

• Labour costs rise

• Firms increase prices

• Inflation rises

• Workers demand further wage rises

• Wage-price spiral develops

Evaluation:

• productivity growth may offset wage increases

• union power important

IMPORTED INFLATION CHAIN

• Exchange rate depreciates

• Import prices rise

• Production costs increase

• Domestic prices rise

• Inflation increases

Evaluation:

• depends on import dependency

• alternative suppliers may exist

DEFLATION CHAIN

• Aggregate demand falls significantly

• Prices fall continuously

• Consumers delay purchases

• Firm revenues fall

• Output contracts

• Unemployment rises

Evaluation:

• productivity-led deflation may be positive

• lower prices improve purchasing power

DISINFLATION CHAIN

• Inflation still positive but slowing

• Price increases become smaller

• Purchasing power stabilises

• Business confidence may improve

Evaluation:

• may occur alongside recession

• unemployment may rise

PHILLIPS CURVE SHORT-RUN CHAIN

• Aggregate demand rises

• Unemployment falls

• Labour shortages develop

• Wages rise

• Inflation rises

Evaluation:

• relationship may weaken long-run

• expectations matter

LONG-RUN PHILLIPS CURVE CHAIN

• Workers expect inflation

• Wage demands increase

• SRAS shifts left

• Unemployment returns to natural rate

• Inflation remains high

Evaluation:

• supply-side improvements may lower natural rate

NATURAL RATE OF UNEMPLOYMENT CHAIN

• Frictional and structural unemployment persist

• Some workers always between jobs

• Economy reaches long-run equilibrium unemployment level

Evaluation:

• supply-side policy may reduce natural rate

• technology may increase it

ACTUAL ECONOMIC GROWTH CHAIN

• Aggregate demand rises

• Output increases

• Employment rises

• Household incomes rise

• Consumption rises

• Living standards improve

Evaluation:

• inflationary pressure possible

• depends on spare capacity

POTENTIAL ECONOMIC GROWTH CHAIN

• LRAS shifts right

• Productive capacity increases

• Sustainable growth rises

• Inflationary pressure reduced

• Living standards improve long-run

Evaluation:

• requires investment and productivity growth

• environmental costs possible

PRODUCTIVITY GROWTH CHAIN

• Worker efficiency improves

• Output per worker rises

• Unit costs fall

• Competitiveness improves

• Economic growth increases

Evaluation:

• requires investment/training

• automation may reduce employment

INVESTMENT-LED GROWTH CHAIN

• Investment increases

• Capital stock rises

• Productivity improves

• LRAS shifts right

• Long-run growth strengthens

Evaluation:

• depends on business confidence

• borrowing costs important

EXPORT-LED GROWTH CHAIN

• Export demand rises

• Aggregate demand increases

• Output and employment rise

• Economic growth strengthens

Evaluation:

• depends on global economy

• exchange rate changes matter

CONSUMPTION-LED GROWTH CHAIN

• Household spending rises

• Aggregate demand increases

• Output expands

• Employment rises

• Economic growth improves

Evaluation:

• may increase imports

• inflationary pressure possible

SUSTAINABLE GROWTH CHAIN

• Economic growth occurs without harming future generations

• Renewable resources used efficiently

• Environmental damage reduced

• Long-run welfare improves

Evaluation:

• transition costs high

• developing countries prioritise rapid growth

INEQUALITY FROM GROWTH CHAIN

• Economic growth increases profits/incomes

• Wealthier groups may benefit more

• Income inequality rises

• Social tensions may increase

Evaluation:

• progressive taxation may reduce inequality

• education access important

LIVING STANDARDS IMPROVEMENT CHAIN

• Employment and incomes rise

• Consumption possibilities increase

• Access to healthcare/education improves

• Welfare rises

Evaluation:

• inflation may reduce real incomes

• inequality may worsen despite growth

POVERTY REDUCTION CHAIN

• Economic growth increases employment

• Household incomes rise

• Tax revenue rises

• Government spending on welfare increases

• Poverty may reduce

Evaluation:

• benefits may not trickle down

• regional inequality possible

RECESSION CHAIN

• Aggregate demand falls

• Output contracts

• Firms reduce employment

• Household incomes fall

• Consumption falls further

• Economic growth becomes negative

Evaluation:

• policy intervention may stabilise economy

• exports may support recovery

OVERHEATING ECONOMY CHAIN

• Aggregate demand rises beyond productive capacity

• Labour shortages occur

• Wages rise

• Inflationary pressure increases

• Economic instability worsens

Evaluation:

• may encourage investment

• contractionary policy may stabilise economy

COMMON PAPER 4 EVALUATION POINTS FOR INFLATION, UNEMPLOYMENT & GROWTH

Always use:

• short-run vs long-run

• spare capacity

• inflationary pressure

• confidence levels

• productivity changes

• labour mobility

• inequality effects

• environmental sustainability

• policy effectiveness

• global economic conditions

PERFECT MACRO ANALYSIS FORMULA

CHANGE IN AD/SRAS/LRAS
→ CHANGE IN OUTPUT
→ CHANGE IN EMPLOYMENT
→ CHANGE IN INFLATION
→ CHANGE IN LIVING STANDARDS
→ LONG-RUN EFFECTS
→ EVALUATION

ULTRA IMPORTANT EXAM CHAIN

Investment rises
→ capital stock increases
→ productivity improves
→ LRAS shifts right
→ sustainable growth rises
→ inflationary pressure decreases

Evaluation:

• depends on business confidence

• time lag exists

• investment may be uneven across sectors

BIGGEST MACRO MISTAKE

Students stop at:

“growth increases living standards.”

Weak.

Strong Paper 4 analysis:
“Economic growth may improve living standards through higher employment and incomes, although the extent of improvement depends on inflation, income distribution and whether growth is environmentally sustainable.”

THAT is A-grade Paper 4 evaluation.
