Differences in Economic Development Between Countries (Copy)

5.4.1 Differences in Economic Development Between Countries

Economic development = improvements in living standards, education, healthcare, productivity, and overall economic well-being — not just income growth.

Countries vary in their development levels because of multiple interrelated factors:

1. Differences in Income Levels

• High-income countries (HICs):
  • High GDP per head.
  • Large disposable incomes → higher living standards.
  • Wider access to goods and services.
• Low-income countries (LICs):
  • Low GDP per head.
  • Many live in poverty (absolute or relative).
  • Incomes concentrated in a small wealthy elite → income inequality.

Impact:

• Higher income → greater tax revenues → more spending on education, healthcare, infrastructure.
• Lower income → weaker government finances → reliance on aid, underinvestment.

MICs:   |███████████
LICs:   |███

2. Differences in Productivity

• HICs:
  • Advanced technology → efficient production.
  • Skilled workforce.
  • High output per worker.
• LICs:
  • Reliance on labour-intensive methods.
  • Poor access to capital equipment.
  • Low productivity → low incomes.

Impact:

• High productivity → competitiveness in global trade.
• Low productivity → difficulty breaking poverty cycle.

MICs:   █████████ 60
LICs:   ███ 20

3. Population Growth

• LICs:
  • High birth rates, declining death rates.
  • Rapid population growth.
  • Strain on education, housing, healthcare.
• HICs:
  • Low or negative population growth.
  • Aging populations.
  • Labour shortages.

Impact:

• LICs: Rising dependency ratios (too many children dependent on small working population).
• HICs: Rising dependency ratios (too many elderly dependents).

4. Size of Primary, Secondary, and Tertiary Sectors

• LICs:
  • Large primary sector (agriculture, raw materials).
  • Low productivity → little value added.
• MICs:
  • Expanding secondary sector (manufacturing, industry).
  • Increasing urbanization.
• HICs:
  • Dominant tertiary sector (services, finance, ICT).
  • Advanced quaternary industries (R&D, biotech).

Impact:

• Moving up the chain (primary → secondary → tertiary) increases incomes and development.

MICs      ████     ████████   ███
HICs      ██       ███        ██████████

5. Differences in Saving and Investment

• HICs:
  • High savings rates → capital accumulation.
  • High levels of FDI (foreign direct investment).
  • Strong banking systems.
• LICs:
  • Low savings → limited funds for investment.
  • Reliance on foreign aid or loans.
  • Risk of debt burdens.

Impact:

• High investment → more capital per worker → productivity growth.
• Low investment → development stagnates.

6. Education

• HICs:
  • Universal access to primary, secondary, and higher education.
  • High literacy rates (>95%).
  • Skilled workforce supports innovation and productivity.
• LICs:
  • Limited access to education.
  • High dropout rates (especially girls).
  • Low literacy → low productivity and incomes.

Impact:

• Education drives human capital development → higher GDP per head.
• Lack of education traps countries in low-income cycles.

HICs: ███████████████████ 99%
MICs: ████████████        80%
LICs: ███████             55%

7. Healthcare

• HICs:
  • Advanced healthcare systems.
  • High life expectancy (80+ years).
  • Low infant mortality.
• LICs:
  • Poor healthcare facilities.
  • Limited access to clean water and sanitation.
  • High infant and maternal mortality.
  • Shorter life expectancy (55–65 years).

Impact:

• Good healthcare → healthier workforce → higher productivity.
• Poor healthcare → lower productivity → poverty trap.

Combined Impacts of Differences

• LICs face “low development traps”:
  • Low incomes → low savings → low investment → low productivity → continued low incomes.
• HICs benefit from “virtuous cycles”:
  • High incomes → high savings and taxes → more investment in education and healthcare → higher productivity → rising incomes.
