Study Notes

Poverty Measurement

Poverty is "pronounced deprivation in well-being."
The conventional view links well-being to command over commodities.
Poverty can be measured in monetary terms (e.g., income, consumption) or through specific consumption types (e.g., house poor, food poor, health poor).
Other dimensions of poverty include malnutrition and literacy.
The broadest approach focuses on capabilities to function in society (e.g., income, education, health, powerlessness, lack of political freedoms).
Four reasons to measure poverty:
- To keep poor people on the agenda
- To identify people in need of interventions
- To monitor policy interventions
- To evaluate the effectiveness of institutions designed to support poor people
The Poverty Reduction Strategy Paper (PRSP) process is a framework to help countries systematically address poverty by measuring, analyzing, and addressing issues.

Learning Objectives

Define poverty.
Summarize the three main views of poverty
State four justifications for measuring poverty.
Outline the Poverty Reduction Strategy Paper process.
Explain the need for technical and analytical training in poverty analysis.

Measurement of Poverty

Measuring poverty requires significant effort, energy, and resources as it requires gathering survey data directly from households.
Four good reasons to measure poverty:
- To keep the subject of poverty on the agenda.
- To accurately identify the poor and target interventions.
- To monitor and evaluate the performance of programs designed to reduce poverty.
- To evaluate and improve the performance of institutions involved in fighting poverty.
The PRSP process, a World Bank initiative, guides countries toward poverty reduction.

Survey Issues

Survey samples can be national or more narrowly defined (e.g., a specific region or group).
The survey unit of analysis is normally the household or individuals.
Longitudinal surveys (using panel data sets) of the same people over time are more complex but provide more in-depth analysis and important time-series data.
Household behaviors should be collected to understand actual welfare.
Collect consumption expenditure or income information.
Survey design should be carefully planned to avoid issues like biases in survey design, sample frame issues, and response bias and avoid misleading data.
Weighting is essential to get reliable statistics from the survey.

Goods Coverage and Valuation

Income is generally used as a welfare measure, but it often understates actual welfare, especially in developing countries.
More comprehensive information on consumption can help estimate real welfare by accounting for items not commonly included in income data, such as home-produced goods and services, changes in asset value and cost of housing.
The main issue is that there’s no universally agreed methodology
Income estimates of individuals might include wages, salaries, household remittances, farm profits, and other incomes generated from various sources.
Consumption, a broadly-defined measure of welfare, includes both purchased goods & services, and goods and services from household production.
It's crucial to account for differences in income and needs as these can impact consumption and well-being.
Consumption data tend to be more reliable because people can remember better their consumption patterns than their income.

Variability of Measurement

Income and consumption can fluctuate month-to-month and year-to-year.
Consumption is more stable and more reliable in terms of measuring permanent income due to regular consumption patterns.
Short-term income fluctuations are averaged out in consumption
Analysts prefer consumption data over income data in developing countries because it’s more closely tied to everyday resources.
Household consumption patterns can be affected by factors such as savings, remittances, risk-sharing arrangements, and access to public resources.

Variability of Measurement & Time Period

Income fluctuates more significantly than consumption.
Consumption tends to be more stable overall.
Households employ strategies to reduce monthly variations, such as saving, or sharing risks with others
Current consumption is preferred to current income in developing countries because consumption tends to reflect current available resources to the household and not be as influenced by short-term variations.

Measuring Durable Goods

Durable goods (goods that last more than one year) are often excluded from survey data.
Measuring the value of durable goods in a household’s consumption is difficult because it is hard to quantify the service they provide across their lifetime.
To calculate their value, the price change in each good is calculated and the interest rate required to retain the asset must be accounted for.
