2. Introduction
• There is a wealth of cross-sectional information on dimensions of
wellbeing in Ethiopia
• There is much less information or understanding of dynamics of poverty
and welfare
– The extent to which households move in and out of poverty over time
– Do public interventions have sustainable impacts on household welfare
– Will agricultural growth reduce poverty
– Are households “chronically poor” or merely “slow growing”
• The Ethiopian Rural Household Survey (ERHS) has been designed to
answer questions such as these
• The ERHS has been supported financially by SIDA, USAID, WFP and the
ESSP.
3. The Ethiopian Rural Household Survey
(ERHS)
• The ERHS is a collaborative effort between the Department of Economics,
Addis Ababa University; the University of Oxford; and IFPRI
• Capacity building has been an important component of the ERHS. More
than 25 doctorates and 60 masters theses by Ethiopians have been based
on the ERHS
• Two ERHS survey rounds were conducted in 1994. Subsequent rounds
have been fielded in:
– 1997 (with special emphasis on gender)
– 1999 (with special emphasis on agricultural productivity)
– 2004 (with special emphasis on recovery from the 2002 drought), and
– 2009 (with special emphasis on gender, productivity and insurance)
4. The Ethiopian Rural Household Survey
• The ERHS is a multi-purpose longitudinal household survey covering 15
villages and approximately 1400 households
• Population shares are consistent with the population shares in the three
main sedentary farming systems
– The plough based cereals farming systems of the Northern and Central Highlands
– Mixed plough/hoe cereals farming systems, and
– Farming systems based around enset
• Sample sizes approximate a self-weighting sample. When considered in
terms of farming system: each person (approximately) represents the
same number of persons found in the main farming systems as of 1994.
• Results should not be regarded as nationally representative. The sample
excludes pastoral households and urban areas and only covers 15 villages
6. The Ethiopian Rural Household Survey:
Further Strengths
• Low attrition. Approximately 84% of households interviewed in 1994 were
re-interviewed in 2009
• Survey covers wide range of topics: demographic change; agricultural
production; non-farm income; consumption; assets; human capital
formation
• Institutional continuity has meant that there is consistency in
measurement of key outcome variables over time
8. CONSUMPTION
• We measure welfare in terms of per capita household consumption
• Consumption is defined narrowly as the sum of values of all food items,
including purchased meals and non-investment non-food items.
– Use values of housing, durables and spending on health and education
expenditures are excluded
– Because there has been accumulation of durables over this period, we
understate consumption growth.
– These values are expressed in monthly per capita terms and deflated using the
food price index with base year 1994.
9. CONSUMPTION
• Mean consumption per capita in 1994 was 71.1 birr per capita per month.
• By 2004, this had risen to 91.5 birr per capita in real (1994) terms.
• This implies mean average consumption growth of 2.6 percent per year. This is
broadly comparable to the average annual rate of growth of real GDP per capita
(2.1 per cent) and the increases reported using nationally representative
household consumption data
• This growth has been distributionally neutral; there was no change in inequality
over this period
10. POVERTY
• Poverty is based on a cost-of-basic-needs approach.
• Using the 1994 data, a food poverty line is constructed using a bundle of food
items that would provide 2300Kcal per adult per day.
• To this, we add a non-food bundle using the method set out in Ravallion and
Bidani (1994) and obtain a poverty line of 50 birr per capita per month in 1994
prices.

12. MOVEMENTS IN AND OUT OF POVERTY BETWEEN
1994 AND 2004
Household is: Per cent
Poor in 1994 and Poor in 2004 18.8
Not poor in 1994 and Poor in 2004 14.2
Poor in 1994 and Not poor in 2004 26.8
Not poor in 1994 and Not poor in 2004 34.7
13. What accounts for this reduction in poverty?
• Improving roads really matters. Access to all-weather roads:
– Increases consumption growth by 16.3%.
– Reduces poverty by 6.9 percentage points
• Improvements in the road quality increase the likelihood of purchasing
crop inputs (by 29–34%, depending on the season) and, for women, of
selling artisanal products (by 39%).
• Receiving at least one extension visit:
– Increases consumption growth by 7.1%.
– Reduces poverty by 9.8 percentage points
• Respondents say that development agents are an important source of
information about the usage of modern inputs and cultivation practices
14. What is poverty reduction faster for some households than for
others?
• Despite this impressive growth, 37% of ERHS households are chronically
poor. Why?
• Location matters!
– A household residing in Gara Godo (an enset growing village) with household
characteristics identical to a household in Sirbana Godeti (close to Debre Zeit) is 80
percent more likely to be chronically poor
– Having access to an all-weather road reduces the likelihood of being chronically
poor by 37 percent
– Closeness to towns helps. Reducing the distance to the nearest town by 12
kilometres lowers the probability of being chronically poor by 38 percent.
• Households residing in villages with, relatively speaking, many female
adults are more likely to be chronically poor.
• Education matters!
– Completion of primary school by the household headed reduces the probability of
being chronically poor by a fifth
16. ERHS 2009
• The most recent round of the ERHS was fielded between April and July,
2009. Data entry was completed by end-August
• In addition to being comparable to earlier rounds, it contains modules
covering:
– Child labor
– Impact of migration
– Crop and technology change in agriculture
– Impact of land registration
– Willingness to pay for weather insurance
– Women’s status and participation in household decisionmaking
– Exposure and consequences of shocks, including rising food prices
– Access to the Productive Safety Nets Program
• Very preliminary analysis of these data shows the following

21. A (partial) research agenda
• What has happened to consumption and poverty?
– Do these changes reflect more than life cycle considerations?
– How has it changed spatially? Are there chronically poor localities or chronically poor
households?
• How has agricultural growth affected consumption and poverty:
– How much does per capita consumption increase given a __% increase in
agricultural production
– How much does per poverty decrease given a __% increase in agricultural
production
– How much does per capita consumption increase given a __% increase in
yield
– How much does poverty decrease given a __% increase in yield
22. A (partial) research agenda
• How have shocks – drought, food price rises and other adverse events –
affected the evolution of poverty in these localities
• How has the position of women within these households changed. Have
welfare improvements been gender neutral?
• Has out-migration benefitted these ERHS households
• Are households willing to purchase weather insurance? What factors,
private (wealth, financial sophistication, past exposure to risk) and public
(access to the PSNP) affect this willingness
23. Summary
• The ERHS tells us that:
– There was considerable growth in consumption between 1994 and 2004 with
the result that there was a significant fall in poverty
– However, a significant fraction of households remained chronically poor:
• Remoteness, poor infrastructure and low levels of human capital were
major factors
• Our preliminary work with the 2009 data suggests that, on average,
several dimensions of wellbeing have continued to improve
• The challenge is to understand what underlines the pattern of these
improvements and their determinants
