What is monetary poverty?
Usually measured relative to a line in adjusted dollars a day (equivalent of what you can buy)
How has the number of people experiencing monetary poverty changed?
The number of individuals experiencing monetary poverty has fallen dramatically in the last 50 years
How has the number of people experiencing monetary poverty changed in Africa?
There has been little to no improvement if not an increase
Which groups consistently feature among those living below the poverty line?
- Those living in rural areas
- Women
- Ethnic minorities and indigenous populations
Why are women typically below the poverty line?
Because they face discrimination in employment, education and health
Give a statistic that shows how indigenous populations compare to the poverty line?
80.6% of indigenous Mexicans sit below the poverty line compared to just 17.9% non-indigenous
What are some desirable properties of poverty measures?
- Anonymity principle
- Population independence principle
- Monotonicity principle
- Distributional sensitivity principle
What are some headcount measures of poverty?
- Poverty headcount (number of individuals below poverty line)
- Headcount ratio
What is the headcount ratio?
The number of people who are poor H as a faction of the population N - Therefore, H/N is the fraction who are poor
What conditions does the headcount ratio satisfy?
It satisfied anonymity and population indpendence but not full monotonicity and it fails on distributional sensitivity
What conditions does the poverty headcount satisfy?
It fails to even satisfy the population independence principle
What does measuring poverty by headcount do to policymakers?
It incentivises to report improvements in these measures - this incentivises policymakers to focus efforts toward those closest to the poverty line
Give some examples of how policy makers may be biased?
- Government policy may exhibit urban bias emphasising job creation for the poor in cities who are closer to the poverty line
- MFIs often focus on the richest of the poor
What was the original poverty objective of the millenium development goals?
Halving poverty
What does the total poverty gap measure?
The amount of income required to lift all those defined as poor to the poverty line
How can we reach the average poverty gap from the total poverty gap?
Dividing by the population N
What does the Poverty Gap Index measure?
The PGI provides a measure of the average extent to which individuals fall below the poverty line as a percentage of the poverty line
How do the total poverty gap and related measures differ to the headcount ratio?
They are sensitive to changes in income below the poverty line
What properties does the total poverty gap satisfy?
Monotonicity, distributional sensitivity however not independent of population size
What properties does the APG and PGI satisfy?
APG and the PGI satisfy all four desirable properties
What does the FGT index stand for?
The Foster-Greer-Thorbecke index
How does the FGT index compare to the others?
Same as the PGI but to the power of alpha
What does a greater alpha measure in the FGT?
The higher the weight placed on those further below the poverty line
What is so harmful about inequality?
- The rate of saving in the economy tends to be lower
- High inequality strengthens the political power of the rich
- High inequality of land ownership may be inefficient
- High inequality facilitates corruption and abuse of public office for private gain
