Abstract
While the measurement and determinants of poverty have been widely studied, vulnerability, or the threat of future poverty, has been more difficult to investigate due to data paucity. We combine nationally representative household data with objective drought and price information to quantify and investigate causes of vulnerability to poverty in Ethiopia. Previous estimates have relied on self-reported shocks and variation in outcomes within a survey, which is inadequate for shocks such as weather and prices that vary more across time than space. We used historical distributions of climate and price shocks in each district to simulate the probable distribution of future consumption for individual households and use these quantify vulnerability to poverty. We find that many Ethiopians are unable to protect their consumption against lack of rainfall and sudden increases in food prices. A moderate drought causes a 9% reduction in consumption for many rural households and recent high inflation has caused a 14% reduction in the consumption of uneducated households in urban areas. We also find that the vulnerability of rural households is considerably higher than that of urban households, despite realized poverty rates being fairly similar. This reflects the fact that the household survey in 2011 was conducted during a year of good rainfall but rapid food price inflation. The results highlight the need for caution in using a snapshot of poverty to target programs, as underlying rates of vulnerability can be quite different from the poverty rate captured at one point in time. The results also suggest that significant welfare gains can be made from risk management in both rural and urban areas.

Publication Vulnerability to Drought and Food Price Shocks(World Bank, Washington, DC, 2016-12)Although the measurement and determinants of poverty have been widely studied, vulnerability, or the threat of future poverty, has been more difficult to investigate due to data paucity. This paper combines nationally representative household data with objective drought and price information to quantify the causes of vulnerability to poverty in Ethiopia. Previous estimates have relied on self-reported shocks and variation in outcomes within a survey, which is inadequate for shocks such as weather and prices that vary more across time than space. Historical distributions of climate and price shocks in each district were used to simulate the probable distribution of future consumption for individual households; these were then used to quantify vulnerability to poverty. The analysis shows that many Ethiopians are unable to protect their consumption against lack of rainfall and sudden increases in food prices. A moderate drought causes a 9 percent reduction in consumption for many rural households, and high inflation causes a 14 percent reduction in the consumption of uneducated households in urban areas. Vulnerability of rural households is considerably higher than that of urban households, despite realized poverty rates being fairly similar. This finding reflects that the household survey in 2011 was conducted during a year of good rainfall but rapid food price inflation. The results highlight the need for caution in using a snapshot of poverty to target programs, as underlying rates of vulnerability can be quite different from the poverty rate captured at one point in time. The results also suggest that significant welfare gains can be made from risk management in both rural and urban areas.Publication Managing Risk with Insurance and Savings : Experimental Evidence for Male and Female Farm Managers in the Sahel(World Bank Group, Washington, DC, 2015-01)Although there is fast-growing policy interest in offering financial products to help rural households manage risk, the literature is still scant as to which products are the most effective. This paper uses a randomized field experiment in Senegal and Burkina Faso to compare male and female farmers who are offered index-based agricultural insurance with those who are offered a variety of savings instruments. The paper finds that female farm managers were less likely to purchase agricultural insurance and more likely to invest in savings for emergencies, even controlling for access to informal insurance and differences in crop choice. It is hypothesized that this finding results from the fact that, although men and women are equally exposed to yield risk, women face additional sources of lifecycle risk -- particularly health risks associated with fertility and childcare -- that men do not. In essence, the basis risk associated with agricultural insurance products is higher for women. Purchasing insurance increased input spending and use more than savings. Those who purchased more insurance realized higher average yields and were better able to manage food insecurity and shocks. This finding suggests that gender differences in demand for financial products can have an impact on productivity, resilience, and welfare.Publication Burkina Faso : Perceived Shocks, Vulnerability, Food Insecurity, and Poverty(Washington, DC, 2013-06-12)Burkina Faso's Poverty Reduction Strategies (PRS) of the 2000s, which were implemented as annually rolled-over Priority Action Programs, focused on four pillars: a) accelerating broad based growth; b) expanding access to social services for the poor; c) increasing employment and income-generating activities for the poor; and d) promoting good governance. Increased public expenditure and targeted social service provision also led to improved access to basic services. In the area of education, progress has been made in terms of school infrastructure. Over the period of 2003-2008, substantial expansion (around 40 percent) of both the number of schools and the number of classrooms was achieved. Controlling and treating epidemic diseases also had good results, thanks to prevention and public awareness efforts and improved hygiene. Meanwhile, the country has been through several exogenous shocks and crises likely to have affected the pattern of poverty outcomes. In the past two decades, Burkina Faso's income per capita growth has been positive and less volatile relative to the past. Recent growth trends appear to be anchored by a general recovery in the primary sector. Household consumption was just as volatile as income per capita in the 1980s, but recovered substantially after the country gained competitiveness in the latter half of the 1990s following devaluation. However, since then, consumption has exhibited much more volatility than output. Finally, most the social indicators show an improvement in Burkina Faso since the early 1980s. Burkina Faso has kept pace with the overall positive trends observed in Sub-Saharan Africa and low income countries.Publication The Drought and Food Crisis in the Horn of Africa : Impacts and Proposed Policy Responses for Kenya(World Bank, Washington, DC, 2011-11)As the world begins to feel the effects of climate change, the frequency of droughts is increasing in the Horn of Africa. In Kenya, the drought and food crisis affect welfare through two main channels. The first channel is the increased mortality of livestock in drought-affected areas, which are home to 10 percent of the country's population. The second channel is by exacerbating increases in food prices, which are largely driven by worldwide price trends. Considering these two channels, this note identifies four broad policy changes that can reduce Kenya's future vulnerability to such shocks: (i) investment in people in the arid and semiarid lands; (ii) reform of Kenya's maize policy; (iii) review of the East African Community grain trade policy; and (iv) formulation of a unified social protection system.Publication Potential for Application of a Probabilistic Catastrophe Risk Modelling Framework to Poverty Outcomes(World Bank, Washington, DC, 2016-06)This paper analyzes the potential to combine catastrophe risk modelling (CAT risk modeling) with economic analysis of vulnerability to poverty using the example of drought hazard impacts on the welfare of rural households in Ethiopia. The aim is to determine the potential for applying a derived set of damage (vulnerability) functions based on realized shocks and household expenditure/consumption outcomes, onto a forward-looking view of drought risk. The paper outlines the CAT risk modeling framework and the role of the vulnerability module, which describes the response of an affected exposure to a given hazard intensity. The need to explicitly account for different household characteristics that determine vulnerability within our model is considered, analogous to how a CAT risk model would differentiate damage functions for buildings by different classes of construction. Results for a regression model are presented, estimating ex-post drought impacts on consumption for heterogeneous household types (e.g. with cattle, safety-net access, illness). Next, the validity/generalizability of the derived functions are assessed, to infer applicability of the derived relationships within a CAT risk modelling framework. In particular, the analysis focuses on external validity: whether the relationships established in the dataset can be used for forecasting outside of the sample used for analysis. The model is stress-tested using statistical methods of resampling. This involves randomly splitting the data into “training” and "testing" datasets. The tests show consistency of results across the datasets. Finally, future plans are outlined with regard to developing a fuller catastrophe risk model to combine with the consumption results.

Publication Conducting Classroom Observations(World Bank, Washington, DC, 2017-07)The “Stallings Classroom Snapshot” instrument, technically called the “Stanford Research Institute Classroom Observation System”, was developed by Professor Jane Stallings for research on the efficiency and quality of basic education teachers in the United States in the 1970s. (Stallings, 1977; Stallings and Mohlman, 1988). The Stallings instrument generates robust quantitative data on the interaction of teachers and students in the classroom, with a high degree of inter-rater reliability (0.8 or higher) among observers with relatively limited training, which makes it suitable for large-scale samples in developing country settings. (Jukes, 2006; Abadzi, 2007; DeStefano et al, 2010; Schuh-Moore et al, 2010). The instrument is language and curriculum-neutral, so results are directly comparable across different types of schools and country contexts, and a growing body of comparative country data from the US and developing countries is available. Use of the Stallings classroom snapshot in more than seven countries in the Latin America and the Caribbean region in recent years has generated a global data base of more than 20,000 different classroom observations in more than 3,600 schools. A public use online database is being created on the World Bank/SIEF (Strategic Impact Evaluation Fund) website. These data provide valuable reference benchmarks for any country or education system that uses the Stallings instrument following the protocol outlined in this guide.Publication Poverty, Prosperity, and Planet Report 2024(Washington, DC: World Bank, 2024-10-15)The Poverty, Prosperity, and Planet Report 2024 is the latest edition of the series formerly known as Poverty and Shared Prosperity. The report emphasizes that reducing poverty and increasing shared prosperity must be achieved in ways that do not come at unacceptably high costs to the environment. The current “polycrisis”—where the multiple crises of slow economic growth, increased fragility, climate risks, and heightened uncertainty have come together at the same time—makes national development strategies and international cooperation difficult. Offering the first post-Coronavirus (COVID)-19 pandemic assessment of global progress on this interlinked agenda, the report finds that global poverty reduction has resumed but at a pace slower than before the COVID-19 crisis. Nearly 700 million people worldwide live in extreme poverty with less than US$2.15 per person per day. Progress has essentially plateaued amid lower economic growth and the impacts of COVID-19 and other crises. Today, extreme poverty is concentrated mostly in Sub-Saharan Africa and fragile settings. At a higher standard more typical of upper-middle-income countries—US$6.85 per person per day—almost one-half of the world is living in poverty. The report also provides evidence that the number of countries that have high levels of income inequality has declined considerably during the past two decades, but the pace of improvements in shared prosperity has slowed, and that inequality remains high in Latin America and the Caribbean and Sub-Saharan Africa. Worldwide, people’s incomes today would need to increase fivefold on average to reach a minimum prosperity threshold of US$25 per person per day. Where there has been progress in poverty reduction and shared prosperity, there is evidence of an increasing ability of countries to manage natural hazards, but climate risks are significantly higher in the poorest settings. Nearly one in five people globally is at risk of experiencing welfare losses due to an extreme weather event from which they will struggle to recover. The interconnected issues of climate change and poverty call for a united and inclusive effort from the global community. Development cooperation stakeholders—from governments, nongovernmental organizations, and the private sector to communities and citizens acting locally in every corner of the globe—hold pivotal roles in promoting fair and sustainable transitions. By emphasizing strategies that yield multiple benefits and diligently monitoring and addressing trade-offs, we can strive toward a future that is prosperous, equitable, and resilient.Publication World Development Report 1994(New York: Oxford University Press, 1994)World Development Report 1994, the seventeenth in this annual series, examines the link between infrastructure and development and explores ways in which developing countries can improve both the provision and the quality of infrastructure services. In recent decades, developing countries have made substantial investments in infrastructure, achieving dramatic gains for households and producers by expanding their access to services such as safe water, sanitation, electric power, telecommunications, and transport. Even more infrastructure investment and expansion are needed in order to extend the reach of services - especially to people living in rural areas and to the poor. But as this report shows, the quantity of investment cannot be the exclusive focus of policy. Improving the quality of infrastructure service also is vital. Both quantity and quality improvements are essential to modernize and diversify production, help countries compete internationally, and accommodate rapid urbanization. The report identifies the basic cause of poor past performance as inadequate institutional incentives for improving the provision of infrastructure. To promote more efficient and responsive service delivery, incentives need to be changed through commercial management, competition, and user involvement. Several trends are helping to improve the performance of infrastructure. First, innovation in technology and in the regulatory management of markets makes more diversity possible in the supply of services. Second, an evaluation of the role of government is leading to a shift from direct government provision of services to increasing private sector provision and recent experience in many countries with public-private partnerships is highlighting new ways to increase efficiency and expand services. Third, increased concern about social and environmental sustainability has heightened public interest in infrastructure design and performance. This report includes the World Development Indicators, which offer selected social and economic statistics for 132 countries.Publication Social Cohesion and Forced Displacement(Washington, DC: World Bank, 2022)This report presents new evidence from 26 background studies on forced displacement and social cohesion to expand the current knowledge base on how to prevent social conflict and promote social cohesion in forced displacement contexts. The background studies are geographically and methodologically diverse. They examine social cohesion in a variety of low-, middle-, and high-income countries across Africa, Asia, Central, and South America, and Europe. Building on this new evidence, the report provides lessons on how development investments and policies can reduce inequalities, alleviate social tensions, and promote social cohesion between and within displaced populations and host communities. Overall, the findings demonstrate that, while displacement can exacerbate existing inequalities and create new inequalities and the potential for conflict, especially in areas with strained services and limited economic opportunities, inclusive policies and development investments can effectively mitigate the negative effects of displacement and promote social cohesion.Publication Classroom Assessment to Support Foundational Literacy(Washington, DC: World Bank, 2025-03-21)This document focuses primarily on how classroom assessment activities can measure students’ literacy skills as they progress along a learning trajectory towards reading fluently and with comprehension by the end of primary school grades. The document addresses considerations regarding the design and implementation of early grade reading classroom assessment, provides examples of assessment activities from a variety of countries and contexts, and discusses the importance of incorporating classroom assessment practices into teacher training and professional development opportunities for teachers. The structure of the document is as follows. The first section presents definitions and addresses basic questions on classroom assessment. Section 2 covers the intersection between assessment and early grade reading by discussing how learning assessment can measure early grade reading skills following the reading learning trajectory. Section 3 compares some of the most common early grade literacy assessment tools with respect to the early grade reading skills and developmental phases. Section 4 of the document addresses teacher training considerations in developing, scoring, and using early grade reading assessment. Additional issues in assessing reading skills in the classroom and using assessment results to improve teaching and learning are reviewed in section 5. Throughout the document, country cases are presented to demonstrate how assessment activities can be implemented in the classroom in different contexts.
