Economic Growth And Sustainability (Copy)

9.2.1 Actual Growth versus Potential Growth in National Output

• Actual Growth:
  • Increase in real GDP/output actually achieved over a period.
  • Influenced by demand-side factors and short-term fluctuations in economy.
• Potential Growth:
  • Increase in the economy’s productive capacity over time.
  • Depends on supply-side factors such as increases in labour force, capital stock, technology improvements.
  • Represents the maximum sustainable growth rate without causing inflation.

9.2.2 Positive and Negative Output Gaps

• Output Gap:
  • The difference between actual output and potential output.
• Positive Output Gap:
  • Actual output > Potential output.
  • Economy overheating; resources over-utilised, leading to inflationary pressures.
• Negative Output Gap:
  • Actual output < Potential output.
  • Economy underperforming; resources underutilised, leading to unemployment and lost output.

9.2.3 Business (Trade) Cycle

• Phases of the Cycle:
  1. Expansion: Rising output, employment, incomes.
  2. Boom: Peak level of economic activity; high output and employment but inflationary pressures.
  3. Recession: Falling output and income; rising unemployment.
  4. Trough: Lowest point; recession ends, output bottoms out.
  5. Recovery: Output and incomes begin to rise again.
• Causes of the Cycle:
  • Fluctuations in investment and consumer confidence.
  • External shocks (oil price shocks, financial crises).
  • Monetary and fiscal policy changes.
  • Innovation cycles and technology changes.
• Role of Automatic Stabilisers:
  • Features of the economy that automatically reduce fluctuations without government intervention.
  • Examples:
    • Progressive taxes reduce disposable income in booms, dampening demand.
    • Unemployment benefits increase during recessions, supporting income and demand.

9.2.4 Policies to Promote Economic Growth and Their Effectiveness

• Supply-Side Policies:
  • Improve productive capacity by enhancing efficiency and incentives.
  • Examples: investment in education/training, infrastructure development, deregulation, tax reforms.
  • Effective for long-term growth but slow to implement.
• Demand-Side Policies:
  • Stimulate aggregate demand to increase output in short run.
  • Examples: government spending, tax cuts, monetary easing.
  • Can cause inflation if economy is near full capacity.
• Effectiveness:
  • Depends on context, timing, and external factors.
  • Structural reforms important for sustainable growth.

9.2.5 Inclusive Economic Growth

• Definition:
  • Economic growth that is broad-based, benefiting all segments of society fairly.
  • Reduces poverty and inequality.
• Impact on Equity and Equality:
  • Inclusive growth narrows income and wealth gaps.
  • Promotes social cohesion and economic stability.
• Policies to Promote Inclusive Growth:
  • Investment in education and healthcare.
  • Social safety nets and welfare programs.
  • Progressive taxation.
  • Support for small and medium enterprises (SMEs).

9.2.6 Sustainable Economic Growth

• Definition:
  • Growth that meets present needs without compromising the ability of future generations to meet their own needs.
• Using and Conserving Resources:
  • Efficient use of natural resources.
  • Development of renewable energy.
  • Waste reduction and recycling.
• Impact on Environment and Climate Change:
  • Economic growth can increase pollution, deforestation, greenhouse gas emissions.
  • Contributes to global warming and climate change.
• Policies to Mitigate Impact:
  • Environmental regulations and standards.
  • Carbon taxes and emissions trading schemes.
  • Investment in green technology.
  • International agreements (e.g., Paris Agreement).
