Syllabus points
- Distinguish economic growth from economic development.
- Explain how development is measured, including composite indicators.
- Explain the barriers to economic development.
- Evaluate strategies to promote development and sustainability.
Growth vs development
Economic growth is an increase in real output (real GDP). Economic development is a broader, multidimensional improvement in living standards — incomes, health, education, freedom and equity. Growth is usually necessary for development but is not sufficient: output can rise while poverty, inequality or environmental damage worsen.
Measuring development
- Single indicators: GDP per capita (PPP-adjusted), life expectancy, literacy rate, infant mortality.
- Human Development Index (HDI): a composite of three dimensions — a long and healthy life (life expectancy), knowledge (schooling), and a decent standard of living (GNI per capita, PPP). Scored 0 to 1.
Evaluating HDI: it is a clear improvement on GDP alone because it captures health and education, and it is comparable across countries. But it still omits inequality, gender disparity, political freedom, and environmental quality — which is why inequality-adjusted and gender-related variants exist.
Barriers to development
| Barrier | Explanation |
|---|---|
| Poverty cycle | Low income → low saving → low investment → low productivity → low income |
| Weak institutions | Corruption, insecure property rights, political instability deter investment |
| Poor infrastructure | Transport, power and communications raise costs and limit market access |
| Low human capital | Weak health and education systems limit productivity |
| Commodity dependence | Volatile export earnings; deteriorating terms of trade |
| Indebtedness | Debt servicing diverts revenue from health, education and investment |
Strategies for development
- Trade-based: trade liberalisation, diversification into higher value-added production, regional integration. *Evaluation:* can drive rapid growth, but exposes producers to global competition and volatility.
- Aid and debt relief: grants, concessional loans, debt cancellation. *Evaluation:* can fund essential infrastructure and human capital, but risks dependency and misallocation where institutions are weak.
- Foreign direct investment (FDI): brings capital, technology and jobs. *Evaluation:* profits may be repatriated and bargaining power is unequal.
- Interventionist: investment in education, health and infrastructure; industrial policy. *Evaluation:* addresses market failure directly but is costly and slow.
- Institutional reform: property rights, anti-corruption, rule of law — often a precondition for the others to work.
Sustainability
Sustainable development meets the needs of the present without compromising the ability of future generations to meet their own needs. The tension is that growth driven by resource depletion and negative externalities (pollution, deforestation, emissions) imposes costs on future generations. Policies include carbon pricing, regulation, investment in renewables, and protection of common-access resources — the same market-failure toolkit applied across time.
Worked example
Two countries both have GDP per capita of $12,000. Country A has life expectancy 78 and mean schooling 12 years; Country B has life expectancy 60 and mean schooling 5 years. Identical income, very different HDI — showing why development requires more than a growth statistic.
Common exam mistakes
- Treating growth and development as the same thing.
- Listing HDI's components without evaluating what it omits (inequality, environment, freedom).
- Recommending one strategy as universally best — context and institutions determine what works.
Exam technique
Distinguish growth from development explicitly, use a named composite indicator with its limitations, then evaluate strategies conditionally against the specific barrier in the question.
Quick revision
- Growth = higher real output; development = broader living standards.
- HDI = health + education + income; omits inequality and environment.
- Barriers: poverty cycle, weak institutions, infrastructure, commodity dependence, debt.
- Strategies: trade, aid, FDI, interventionist, institutional — all context-dependent.
- Sustainability: meeting present needs without compromising future generations.
