Abstract
The spike in food prices between 2005 and the first half of 2008 has highlighted the vulnerabilities of poor consumers to higher prices of agricultural goods and generated calls for massive policy action. This paper provides a formal assessment of the direct and indirect impacts of higher prices on global poverty using a representative sample of 63 to 93 percent of the population of the developing world. To assess the direct effects, the paper uses domestic food consumer price data between January 2005 and December 2007--when the relative price of food rose by an average of 5.6 percent --to find that the implied increase in the extreme poverty headcount at the global level is 1.7 percentage points, with significant regional variation. To take the second-order effects into account, the paper links household survey data with a global general equilibrium model, finding that a 5.5 percent increase in agricultural prices (due to rising demand for first-generation biofuels) could raise global poverty in 2010 by 0.6 percentage points at the extreme poverty line and 0.9 percentage points at the moderate poverty line. Poverty increases at the regional level vary substantially, with nearly all of the increase in extreme poverty occurring in South Asia and Sub-Saharan Africa.

Publication The Economic Value of Weather Forecasts: A Quantitative Systematic Literature Review(Washington, DC: World Bank, 2025-09-10)This study systematically reviews the literature that quantifies the economic benefits of weather observations and forecasts in four weather-dependent economic sectors: agriculture, energy, transport, and disaster-risk management. The review covers 175 peer-reviewed journal articles and 15 policy reports. Findings show that the literature is concentrated in high-income countries and most studies use theoretical models, followed by observational and then experimental research designs. Forecast horizons studied, meteorological variables and services, and monetization techniques vary markedly by sector. Estimated benefits even within specific subsectors span several orders of magnitude and broad uncertainty ranges. An econometric meta-analysis suggests that theoretical studies and studies in richer countries tend to report significantly larger values. Barriers that hinder value realization are identified on both the provider and user sides, with inadequate relevance, weak dissemination, and limited ability to act recurring across sectors. Policy reports rely heavily on back-of-the-envelope or recursive benefit-transfer estimates, rather than on the methods and results of the peer-reviewed literature, revealing a science-to-policy gap. These findings suggest substantial socioeconomic potential of hydrometeorological services around the world, but also knowledge gaps that require more valuation studies focusing on low- and middle-income countries, addressing provider- and user-side barriers and employing rigorous empirical valuation methods to complement and validate theoretical models.Publication Direct and Indirect Impacts of Transport Mobility on Access to Jobs: Evidence from South Africa(Washington, DC: World Bank, 2025-11-12)Access to jobs is essential for economic growth. In Africa, unemployment rates are notably high. This paper reexamines the relationship between transport mobility and labor market outcomes, with a particular focus on the direct and indirect effects of transport connectivity. As predicted by theory, wages are influenced by the level of commuting deterrence. Generally, higher earnings are associated with longer commute times and/or higher commuting costs. Local accessibility is also important, especially for individuals with time constraints. Both direct and indirect impacts are found to be significant in South Africa, where job accessibility has been challenging since the end of apartheid. For the direct impact, the wage elasticity associated with commuting costs is significant. Returns on commute are particularly high for women. Local accessibility to socioeconomic facilities, such as shops and health services, is also found to have a significant impact, consistent with the concept of mobility of care. To enhance employment, therefore, it is crucial to connect people not only to job locations but also to various socioeconomic points of interest, such as markets and hospitals, in an integrated manner. This integration will enable individuals to spend more time working and commuting longer distances.Publication The Macroeconomic Implications of Climate Change Impacts and Adaptation Options(Washington, DC: World Bank, 2025-05-29)Estimating the macroeconomic implications of climate change impacts and adaptation options is a topic of intense research. This paper presents a framework in the World Bank's macrostructural model to assess climate-related damages. This approach has been used in many Country Climate and Development Reports, a World Bank diagnostic that identifies priorities to ensure continued development in spite of climate change and climate policy objectives. The methodology captures a set of impact channels through which climate change affects the economy by (1) connecting a set of biophysical models to the macroeconomic model and (2) exploring a set of development and climate scenarios. The paper summarizes the results for five countries, highlighting the sources and magnitudes of their vulnerability --- with estimated gross domestic product losses in 2050 exceeding 10 percent of gross domestic product in some countries and scenarios, although only a small set of impact channels is included. The paper also presents estimates of the macroeconomic gains from sector-level adaptation interventions, considering their upfront costs and avoided climate impacts and finding significant net gross domestic product gains from adaptation opportunities identified in the Country Climate and Development Reports. Finally, the paper discusses the limits of current modeling approaches, and their complementarity with empirical approaches based on historical data series. The integrated modeling approach proposed in this paper can inform policymakers as they make proactive decisions on climate change adaptation and resilience.Publication From Policy to Practice: Lessons from the Implementation of the Refugee Work Rights Policy in Ethiopia(Washington, DC: World Bank, 2025-11-10)This paper examines the early implementation of Ethiopia’s refugee work rights policy, with a focus on the issuance of permits that enable refugees to engage in economic activities. Building on significant legal and institutional advances under the 2019 Refugee Proclamation and subsequent directives, the analysis explores how these reforms are being operationalized in practice. Using a mixed-methods approach, combining document review, administrative data analysis, and semi-structured interviews, the paper identifies both progress and remaining challenges. Permit issuance has increased since the adoption of detailed operational guidance in 2024, reflecting the Government of Ethiopia’s commitment to operationalizing its progressive legal framework and ensuring that refugees can exercise their right to work. However, take-up remains modest, with about 5.2 percent of the working-age population holding a permit. Preliminary evidence suggests that coordination gaps, limited subnational capacity, low awareness among refugees and employers, and disincentives to formalize in a largely informal labor market are contributing to the low take-up. The paper offers policy suggestions, grounded in the Ethiopian context and emerging evidence, to help translate legal commitments into improved labor market outcomes for refugees.Publication Monitoring Global Aid Flows: A Novel Approach Using Large Language Models(Washington, DC: World Bank, 2025-11-04)Effective monitoring of development aid is the foundation for assessing the alignment of flows with their intended development objectives. Existing reporting systems, such as the Organisation for Economic Co-operation and Development’s Creditor Reporting System, provide standardized classification of aid activities but have limitations when it comes to capturing new areas like climate change, digitalization, and other cross-cutting themes. This paper proposes a bottom-up, unsupervised machine learning framework that leverages textual descriptions of aid projects to generate highly granular activity clusters. Using the 2021 Creditor Reporting System data set of nearly 400,000 records, the model produces 841 clusters, which are then grouped into 80 subsectors. These clusters reveal 36 emerging aid areas not tracked in the current Creditor Reporting System taxonomy, allow unpacking of “multi-sectoral” and “sector not specified” classifications, and enable estimation of flows to new themes, including World Bank Global Challenge Programs, International Development Association–20 Special Themes, and Cross-Cutting Issues. Validation against both Creditor Reporting System benchmarks and International Development Association commitment data demonstrates robustness. This approach illustrates how machine learning and the new advances in large language models can enhance the monitoring of global aid flows and inform future improvements in aid classification and reporting. It offers a useful tool that can support more responsive and evidence-based decision-making, helping to better align resources with evolving development priorities.

Publication Armenia : Poverty Update Using Revised Poverty Lines(World Bank, 2011-06-01)This study has two objectives, the first of which is to revise the national poverty lines of Armenia. The Government of Armenia expressed its desire for revised poverty lines that more accurately reflect the current consumption and expenditure patterns of the population. The work was jointly undertaken by the client counterparts and the World Bank. The second objective of this study is to assess the changes in poverty incidence in the aftermath of the global recession. This note updates the poverty numbers using the full dataset from the 2009 Integrated Living Conditions Survey (ILCS). It estimates how much poverty incidence increased during the crisis, and draws implications for mitigation measures. All poverty indices increased during the crisis and continued to worsen during the macroeconomic recovery.Publication Are Low Food Prices Pro-Poor? Net Food Buyers and Sellers in Low-Income Countries(World Bank, Washington, DC, 2008-06)There is a general consensus that most of the poor in developing countries are net food buyers and food price increases are bad for the poor. This could be expected of urban poor, but it is also often attributed to the rural poor. Recent food price increases have increased the importance of this issue, and the possible policy responses to these price increases. This paper examines the characteristics of net food sellers and buyers in nine low-income countries. Although the largest share of poor households are found to be net food buyers, almost 50 percent of net food buyers are marginal net food buyers who would not be significantly affected by food price increases. Only three of the nine countries examined exhibited a substantial proportion of vulnerable households. The average incomes (as measured by expenditure) of net food buyers were found to be higher than net food sellers in eight of the nine countries examined. Thus, food price increases, ceteris paribus, would transfer income from generally higher income net food buyers to poorer net food sellers. The analysis also finds that the occupations and income sources of net sellers and buyers in rural areas are significantly different. In rural areas where food production is the main activity and where there are limited non-food activities, the incomes of net buyers might depend on the incomes and farming activities of net food sellers. These results suggest the need for reevaluation of the consensus on the impact of food prices on food needs. Further work on the regional differences, and more important, on the second order effects, are necessary to answer these questions more precisely. Only on the basis of further analysis can we start generating better policy responses.Publication Mali : Poverty and Gender Notes(Washington, DC, 2013-05-31)Mali is one of the poorest countries in the world, with a gross domestic product (GDP) per capita of about $ 691 in 2010. Mali's steady per capita GDP growth was accompanied with a significant decline in the poverty rate, from 55.6 percent in 2001 to 43.6 percent in 2009-10. Mali's rapid population growth still has led to an increase of the overall number of people living in poverty, and is constraining progress in terms of per capita health and education outcomes. High fertility rates and gender imbalances are key drivers of Mali's poverty dynamics. The present report compiles three different notes, emphasizing the interrelation between poverty, demographics and gender imbalances. The first note discusses the evolution of poverty in Mali since 2001. The second note reviews recent demographic trends and related policies. The third note reports on the latest available data on females in business and employment within the formal sector. The compilation of these three notes aims to stimulate debates and the exploration of policy options to tackle poverty through its interactions with fertility and gender imbalances. It also highlights conclusion of each note.Publication Poverty Status in Afghanistan(World Bank, Washington, DC, 2010-07)Poverty reduction is one of the three key objectives of the Afghanistan national development strategy. The poverty profile is an important element in the information kit of the policymaker that helps focus policy to attain this objective. A poverty profile is standard methodology to describe the extent and nature of poverty in a country or region. It assesses the magnitude of poverty and its distribution across geographic and socioeconomic domains, provides information on the characteristics of the poor, illustrates the heterogeneity among the poor, and identifies correlates of poverty. The report describes the multidimensional nature of poverty by encompassing the nonmonetary dimensions of poverty, particularly education and health status, and vulnerability to shocks. Tables in the report are also disaggregated by region, income sources, gender, and many socioeconomic characteristics. In addition to providing a picture of the many dimensions of poverty, it is important to also recognize that the poverty estimates in this report are the first nationally representative, seasonally smoothed estimates of wellbeing for Afghanistan. Because previously no such existing estimates were available, the provision of these estimates in this report is new analysis that substantially fills key knowledge gaps in our understanding of the poverty situation in Afghanistan.Publication The Impacts of Cash and In-Kind Transfers on Consumption and Labor Supply : Experimental Evidence from Rural Mexico(Washington, DC: World Bank, 2008-11)The authors use the unique experimental design of the Food Support Program (Programa Apoyo Alimentario) to analyze in-kind and cash transfers in the poor rural areas of southern states of Mexico. They compare the impacts of monthly in-kind and cash transfers of equivalent value (mean share 11.5 percent of pre-program consumption) on household welfare as measured by food and total consumption, adult labor supply, and poverty. The results show that approximately two years later the transfer has a large and positive impact on total and food consumption. There are no differences in the size of the effect of transfer in cash versus transfers in-kind on consumption. The transfer, irrespective of type, does not affect overall participation in labor market activities but induces beneficiary households to switch their labor allocation from agricultural to nonagricultural activities. The analysis finds that the program leads to a significant reduction in poverty. Overall, the findings suggest that the Food Support Program intervention is able to relax the binding liquidity constraints faced by poor agricultural households, and thus increases both equity and efficiency.

Publication Democratic Republic of Congo Urbanization Review(Washington, DC: World Bank, 2018)The Democratic Republic of Congo has the third largest urban population in sub-Saharan Africa (estimated at 43% in 2016) after South Africa and Nigeria. It is expected to grow at a rate of 4.1% per year, which corresponds to an additional 1 million residents moving to cities every year. If this trend continues, the urban population could double in just 15 years. Thus, with a population of 12 million and a growth rate of 5.1% per year, Kinshasa is poised to become the most populous city in Africa by 2030. Such strong urban growth comes with two main challenges – the need to make cities livable and inclusive by meeting the high demand for social services, infrastructure, education, health, and other basic services; and the need to make cities more productive by addressing the lack of concentrated economic activity. The Urbanization Review of the Democratic Republic of Congo argues that the country is urbanizing at different rates and identifies five regions (East, South, Central, West and Congo Basin) that present specific challenges and opportunities. The Urbanization Review proposes policy options based on three sets of instruments, known as the three 'I's – Institutions, Infrastructures and Interventions – to help each region respond to its specific needs while reaping the benefits of economic agglomeration The Democratic Republic of the Congo is at a crossroads. The recent decline in commodity prices could constitute an opportunity for the country to diversify its economy and invest in the manufacturing sector. Now is an opportune time for Congolese decision-makers to invest in cities that can lead the country's structural transformation and facilitate greater integration with African and global markets. Such action would position the country well on the path to emergence.Publication Strengthening Competitiveness In Bangladesh—Thematic Assessment(Washington, DC: World Bank, 2016-07-15)This is volume 2 of a three-volume publication on Bangladesh’s trade prospects. Bangladesh’s ambition is to build on its very solid growth and poverty reduction achievements, and accelerate growth to become a middle income country by 2021, and share prosperity more widely amongst its citizens. This includes one of its greatest development challenges: to provide gainful employment to the over 2 million people that will join the labor force each year over the next decade. Moreover, only 54.1 million of its 94 million working age people are employed. Bangladesh needs to use its labor endowment even more intensively to increase growth and, in turn, to absorb the incoming labor. The Diagnostic Trade Integration Study identifies the following actions centered around four pillars to sustain and accelerate export growth: (1) breaking into new markets through a) better trade logistics to reduce delivery lags ; as world markets become more competitive and newer products demand shorter lead times, to generate new sources of competitiveness and thereby enable market diversification; and b) better exploitation of regional trading opportunities in nearby growing and dynamic markets, especially East and South Asia; (2) breaking into new products through a) more neutral and rational trade policy and taxation and bonded warehouse schemes; b) concerted efforts to spur domestic investment and attract foreign direct investment, to contribute to export promotion and diversification, including by easing the energy and land constraints; and c) strategic development and promotion of services trade; (3) improving worker and consumer welfare by a) improving skills and literacy; b) implementing labor and work safety guidelines; and c) making safety nets more effective in dealing with trade shocks; and (4) building a supportive environment, including a) sustaining sound macroeconomic fundamentals; and b) strengthening the institutional capacity for strategic policy making aimed at the objective of international competitiveness to help bring focus and coherence to the government’s reform efforts. This second volume provides in-depth analysis across seven cross-cutting themes that underpin most of the findings of pillars 1 and 2 above.Publication Firm-Level Technology Adoption in Vietnam(World Bank, Washington, DC, 2021-03)This paper describes the results of a new firm survey to measure technology use and adoption implemented prior to the COVID-19 pandemic in Vietnam. It analyzes the use and adoption of technology among Vietnamese firms and identifies some of the key barriers to adoption and diffusion. The analysis offers new and important stylized facts on firm-level use of technologies. First, although access to the internet is almost universal in Vietnam, firms had low digital readiness to face the COVID-19 pandemic; and the share of establishments with their own website, social media, and cloud computing is still small. Second, the use of Industry 4.0 technologies is incipient. Third, the technology gap with the use of frontier technologies in some general business functions, such as quality control, production planning, sales, and sourcing and procurement, is large. Fourth, the manufacturing sector faces the largest technological gap, larger than services and agricultural firms. The analysis of the main barriers and drivers to technology adoption and use shows the importance of good management quality for technology adoption, and that there is a technology premium associated with exporting activities. Finally, the analysis also shows that firms are largely unaware of the available public policy support for technology upgrading.Publication Bangladesh Development Update, October 2013(Washington, DC, 2013-10)Economic performance has remained resilient to global headwinds and disruptive politics in Bangladesh in FY13. Gross Domestic Product (GDP) growth decelerated for the second year in a row to 6 percent. Disruptions caused by political strife, deepening political tensions relating to the impending political transition and the inadequacies of improvements in the provision of power, gas and infrastructure were the key factors in the growth slowdown. These contributed to weakening investor confidence leading to a 1.2 percent decline in the private investment rate. Recovery in remittance growth contributed to sustaining private consumption growth which combined with a significant rise in public investment and robust increases in exports helped maintain GDP growth above the average 5 percent growth in developing countries in 2013. Growth declined in both the agriculture and service sectors while industrial growth increased slightly. Inflation decelerated but remained high. Annual average inflation declined from 8.7 percent in FY12 to 6.8 percent in FY13. External balances have improved further. The external trade deficit decreased significantly due primarily to an increase in export growth over FY12 and flat import payments. The banking system remains under stress and capital market activities have been weak. Several financial scams and resultant loan defaults in the state-owned commercial banks moved them into a position of insolvency, which needs to be urgently addressed. The most pressing challenges lie in maintaining economic and financial reforms, rebuilding the image of the garment sector, and removing supply bottlenecks. Some structural reforms have moved forward. The International Monetary Fund's extended credit facility is on track with significant progress in strengthening macroeconomic conditions and structural policies under the extended credit facility arrangement. The new value added tax law has moved firmly into the implementation phase; the National Board of Revenue has introduced an online tax registration system; amendments to the Banking Companies Act have been passed and progress is being made in identifying critical weaknesses in the state-owned commercial banks; the FY14 budget introduced revenue reforms such as increasing the corporate profit tax rate on cigarette manufacturing companies and reducing the nominal protection rate to 28.1 percent in FY14 from 28.9 percent in FY13. Removing Bangladesh's favored access to the United States market under the Generalized System of Preferences program may not hurt Bangladesh's garment industry unduly. If the European Union were to suspend Bangladesh's favored access to its markets, Bangladesh could see its total exports fall by as much as 4.1 to 8 percent.Publication Vietnam(World Bank, Hanoi, 2020-05-01)Following from Vietnam’s ratification of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) in late 2018 and its effectiveness from January 2019, and the European Parliament’s recent approval of the European Union-Vietnam Free Trade Agreement (EVFTA) and its subsequent planned ratification by the National Assembly in May 2020, Vietnam has further demonstrated its determination to be a modern, competitive, open economy. As the COVID-19 (Coronavirus) crisis has clearly shown, diversified markets and supply chains will be key in the future global context to managing the risk of disruptions in trade and in supply chains due to changing trade relationships, climate change, natural disasters, and disease outbreaks. In those regards, Vietnam is in a stronger position than most countries in the region. The benefits of globalization are increasingly being debated and questioned. However, in the case of Vietnam, the benefits have been clear in terms of high and consistent economic growth and a large reduction in poverty levels. As Vietnam moves to ratify and implement a new generation of free trade agreements (FTAs), such as the CPTPP and EVFTA, it is important to clearly demonstrate, in a transparent manner, the economic gains and distributional impacts (such as sectoral and poverty) from joining these FTAs. In the meantime, it is crucial to highlight the legal gaps that must be addressed to ensure that national laws and regulations are in compliance with Vietnam’s obligations under these FTAs. Readiness to implement this new generation of FTAs at both the national and subnational level is important to ensure that the country maximizes the full economic benefits in terms of trade and investment. This report explores the issues of globalization and the integration of Vietnam into the global economy, particularly through implementation of the EVFTA.
