Economic Development – Poverty (Cambridge IGCSE 0455)
Objective
To understand the causes of poverty and evaluate the policies that can alleviate poverty and redistribute income, with particular reference to how economic growth can be used as a tool for poverty reduction.
1. Definitions (AO1)
Absolute poverty: living below a fixed poverty line that reflects the minimum income needed to meet basic needs (e.g., the World Bank’s US$1.90 per day).
Relative poverty: living significantly below the average standard of living in a society (often measured as a percentage of median income).
Poverty head‑count ratio: the proportion of the population whose income is below the defined poverty line.
Formula:Head‑count ratio = (Number of people below the poverty line ÷ Total population) × 100 %
2. Causes of Poverty (AO1)
Unemployment – especially structural and frictional unemployment that leaves people without a regular income.
Low wages – even when employed, workers may earn less than the minimum needed for a decent standard of living.
Illness & poor health – high disease burden and limited access to health services reduce productivity and increase out‑of‑pocket expenses.
Age‑related factors – children, the elderly and other dependents often have little or no income of their own.
Environmental factors – natural disasters, climate change and resource depletion can destroy livelihoods, particularly in rural/agricultural economies.
Other factors (often highlighted in the syllabus)
Insufficient economic growth
Unequal distribution of income and wealth
Limited access to quality education and health services
Poor infrastructure and low productivity
Political instability and weak institutions
3. Policy Approaches to Alleviate Poverty
Policies fall into two broad categories. Both aim to raise living standards for the poorest groups, but they work in different ways.
3.1 Growth‑oriented policies
Increase the size of the economy (GDP) so that more resources become available for all.
Investment in physical capital – roads, ports, electricity, water supply.
Example: Kenya’s “LAPSSET” corridor created construction jobs and improved market access for farmers.
Trade liberalisation – reducing tariffs and non‑tariff barriers, promoting export‑led growth.
Example: Bangladesh’s garment export boom after adopting trade‑friendly policies.
Technology adoption & R&D – incentives for firms to adopt new production techniques; support for innovation hubs.
3.2 Redistributive (equity‑focused) policies
Directly target the income and wealth gap.
Progressive taxation – higher tax rates on higher incomes or wealth; revenue used for social programmes.
Social safety nets – cash transfers, unemployment benefits, food or fuel subsidies; often means‑tested.
Public provision of services – free or heavily subsidised health care, primary education, clean water.
Minimum‑wage legislation – sets a legal floor for wages to protect low‑skill workers.
Land reform – redistribution of under‑utilised land to smallholder farmers; can improve agricultural productivity.
Micro‑finance and credit schemes – provide small loans to entrepreneurs who lack collateral.
4. How Economic Growth Reduces Poverty
Job creation – new firms and expanded sectors (e.g., manufacturing, services) increase demand for labour, lowering unemployment.
Higher incomes – growth raises average wages and profits; per‑capita income rises, moving households above the poverty line.
Mathematically, if Y is national income and N the population, per‑capita income y = Y/N. When Y grows faster than N, y rises, reducing the poverty head‑count ratio.
5. Evaluating Policy Effectiveness
Examiners look for a balanced evaluation using the following criteria:
Efficiency – does the policy achieve the desired outcome with the least waste of resources?
Equity (fairness) – does it target the poorest groups and reduce income inequality?
Administrative feasibility – can the government implement, monitor and enforce it effectively?
Fiscal sustainability – can the policy be financed without creating large, unsustainable deficits?
Potential side‑effects – e.g., work disincentives, inflationary pressures, or damage to domestic industries.

Disadvantages / Risks
Infrastructure investment
Improves productivity and lowers transport costs; creates construction jobs.
Potential for conflict; requires secure land‑title systems.
7. Suggested Diagram for Exams
Typical relationship between GDP per‑capita (x‑axis) and the poverty head‑count ratio (y‑axis). The downward‑sloping curve shows that higher per‑capita income is associated with lower poverty rates. Mark three points to illustrate: (i) rapid growth with a large fall in poverty, (ii) modest growth with a small fall, and (iii) growth without poverty reduction (highlighting the need for inclusive policies).
8. Concluding Remarks
For sustainable poverty reduction, policymakers must combine:
Growth‑oriented reforms that expand the size of the economy and create jobs, and
Redistributive measures that ensure the benefits of growth reach the poorest groups.
Balancing efficiency, equity, administrative feasibility and fiscal sustainability is essential. Well‑targeted social safety nets, investment in human capital and infrastructure, and a stable macro‑economic environment together provide the most robust pathway to lifting people out of poverty.
