Chapter 8Government intervention to reduce inequality and poverty
Inequality and poverty in SADC countries:
Measures to quantify inequality and poverty:
1. Poverty rates → % of the population living below the “poverty line” → US$ 3.20 per
person per day (International poverty line determined by the World bank in 2018).
2. Gini coefficient → measure of income distribution → deviation of actual income
distribution in a country from the line of absolute equality
- 0 > GC < 1 → closer to 1 = more unequal income distribution
- 0 = perfect equality → Lorenz curve is the same as the actual distribution.
- 1 = perfect inequality → all income goes to one member of the population.

Angola (2008) 55,7 0,427 5,4 48,5

- Table analysis:
o Poverty is spread across all SADC countries (except Seychelles and
Mauritius)
o In Mozambique → population is equally poor → moderate GC
o In SA → income spread is more significant → high GC
▪ Poverty rate (37,6%) is high for a middle-income country in
comparison to other middle-income countries (Brazil (8,0%);
Colombia (11,8%) and Indonesia 30,9%).
- Gini coefficient income shares per income quintile for SA:
o Quintile 1 (lowest) = 2,4%
o Quintile 2 = 4,8%
o Quintile 3 = 8,2%
o Quintile 4 = 16,5%
o Quintile 5 (highest) = 68,2%
o NOTE! Lowest 40% of the population only earn 7.2% of SA’s total income.

, o GC is derived from the Lorenz curve → shows cumulative income shares
of cumulative fractions of the population.
o GC is the measure of the extent to which actual income
distribution deviates from the Lorenz curve.

Budget redistribution and poverty alleviation:
Fiscal policy tools used to reduce poverty and inequality:
- Include taxes, government expenditure programmes and regulation.
- Short term → national budget an important instrument to influence distribution of
private earnings.
- Long term → (indirect effects of fiscal system) → government spending and taxes
influence economic growth rates, investment in physical and human capital
(major determinants of distribution of earnings from capital and labour activity)
o Government needs to effect structural changes to influence economic
output and growth → big challenge = design a system to help the poor
and empower people to lift themselves out of poverty (human capital
investment)
Distinctions in income:
- Primary income (Yp) → personal income of individual, household or group
reflecting the actual income received in cash or in kind.
o Gross income (income before tax)
o Disposable income
- Secondary income (Ys): Primary income – direct taxes paid from Yp (disposable
income) + value of government services consumed.
o Income after government intervention.
𝑌𝑠 = 𝑌𝑝 – 𝑇𝑑 + 𝐺
Td = direct taxes G = government expenditure
- Two policy approaches will be examined to change Yp and Ys through
government intervention.
