PovertyWhat is poverty?• “Poverty is the inability of an individual

or a family to command sufficient resources to satisfy basic needs” (Fields Ch4)

Money-metric or multi-dimensional framework?• We are looking at money-metric, but MDF in

brief: • Income and expenditure justified as poverty measure

partly because of presumed correlation with well-being and empowerment.

• Important to understand that money is not end in itself, but means to an end

• $ correlated with food, shelter, nutrition etc but not well correlated with access to public services, safety, human rights etc

• Amartya Sen = Godfather

4

Poverty• Focus axiom: The only thing we need to know

about the non-poor are how many there are (poverty not inequality!).• Tony Blair was “intensely relaxed” about the millions

earned by David Beckham (a footballer) provided that child poverty fell.

• Absolute vs Relative measure of poverty?• $1/day or 30% mean income?

5

PovertyMeasuring poverty?

• Why do we need to measure it?• How do we measure it?

• Foster Greer Thorbecke (FGT)• Poverty Headcount ratio (α = 0)• Poverty Gap ratio (α = 1)• Poverty Severity ratio (α = 2)

Poverty - SA• Impact of social grants on poverty?• Labour market – focus for solving

inequality? (SVDB)

“Wage inequality, deeply rooted in South Africa’s history, plays a central role in overall income distribution, and patterns of human capital development are fundamental to the future growth path and therefore to poverty and income distribution. The paper therefore concludes that reducing inequality substantially is currently unlikely without a massive increase in the human capital of those presently poor, but that prospects in this regard are inauspicious” (Van der Berg, 2010)

Poverty – SA, the gist• Poverty has not gone up since the

transition• Differing views on when and how much

it came down• Depends which surveys you use, also

which method (Survey-method or national accounts anchoring)

• Common-sense methods are helpful• Hunger decreased

Back to Beckham…
