- Passé-Smith Could it be that the whole world is
already rich?
4Development as Freedom
- The process of expanding the real freedoms that
people enjoy (Sen 3) - Capability Deprivation vs. Income Poverty
5Why is Measurement Important?
- The problem of international comparisons poverty
lines differ across countries - The World Banks 1-a-day and 2 a day poverty
lines as a benchmark - 1-a-day
- corresponds with poverty line in a low-income
country. - below this level of income, basic caloric and/or
nutrient intake is probably inadequate - Implying not only hunger and malnutrition, but
also fundamental limits on human capacities

12Measuring Poverty Monetary or Income Approaches
- Income is an important component of well-being
- Measurement via household income and expenditure
(consumption) survey - Income, from all sources including
- Wages
- Sale of output (minus inputs and investment)
- Private transfers (for example, remittances)
- Public transfers (subsidies, food stamps)
- (Impute cash value to grown food)
13Poverty Lines
- Allows for creation of poverty lines
- Across countries the 1-a-day and 2-a-day
assessments - But countries differ in level of income and
prices, and therefore poverty lines differ too - Absolute approaches some minimum needs,
typically measured in terms of caloric intake - .but ultimately socially defined from 1-a-day
to US 18,000 a year (50 a day) for a family of
four.
14Poverty Assessments
- Poverty lines show aggregate trends in poverty
over time - but can also be used as part of more
disaggregated poverty assessments that identify
potential target groups - and allow for tests of hypotheses

19Critique of Income Measures I
- Income is instrumental to some need
translation of income into fulfillment of need
varies by factors such as age and disability
(Sen) - Physical quality-of-life measures
- Caloric and nutrient intake
- Enfant mortality
- Literacy
- Life expectancy
- Does income correlate with physical quality of
life measures?

22Critique of Income Measures II
- The welfare of the poor is highly dependent on
government infrastructure and services - Households with equal incomes may have different
access to services (urban vs. rural households in
particular) - Examples
- Access to potable water
- Schools and clinics
- Roads

24Critique of Income Measures III
- Income is a snapshot
- but the incomes of poor households are often
highly variable over time - because of exposure to risks of various sorts.
- Income at one point in time does not capture risk
that income may fall. - Chronic vs. transitory poverty.

26Critique of Income Measures IV The Significance
of Assets
- Participatory poverty assessments (PPA Voices of
the Poor) - Surprise the poor talk less about income than
expected, but repeatedly return to the importance
of various assets - Assets are things of value owned by the household
which can generate or increase income and buffer
against losses in income - Examples?
27Assets of Significance to the Poor
- Financial assets or savings are typically
limited - Physical capital (land, animals, housing)
- Human capital (health and education)
- Social capital the value of networks and the
cost of exclusion - Environmental assets and commons
28The Significance of Assets
- We have neither land nor work. . . . Some of us
have land in the reserve, but we cant transport
our products from there because it is too far. It
is difficult to carry them, and since I dont
have land here, and only in the reserve, I am
poor. - Ecuador 1996
- In my family if anyone becomes seriously ill, we
know that we will lose him because we do not even
have enough money for food so we cannot buy
medicine. - Vietnam 1999a
29The Significance of Assets
- I used to never worry about my illiteracy and the
fact that I was not able to send my children to
school, as long as we had something to eat. But
now . . . I realize that my children are in
trouble for life because they cannot get any
decent job if they dont know how to read and
write. - Swaziland 1997
- You have to cultivate networks and contacts with
people with power and influence to secure a
livelihood and future. - Pakistan 1993
