Abstract
This paper investigates the causal impact of a Covid-19 lockdown policy on the Comoros's household welfare, poverty, and labor market outcomes. The identification strategy uses the national government lockdown policy implemented to curtail the unexpected outbreak of Covid-19. The lockdown policy coincided with the 2020 Harmonized Survey on Living Conditions of Households data collection, lending itself to a quasi-natural experiment in which households that were interviewed before the lockdown policy fall into the control group, while those that were interviewed after the lockdown fall into the treated group. The paper explores the impact of the Covid-19 using descriptive regression analysis and estimates the causal impact using matching techniques. The analysis finds a reduction in household expenditure, increased poverty, and a reduction in the likelihood of employment. Investigation of differential impacts along the expenditure distribution finds larger impacts at the top of the distribution, suggesting that Covid-19 may have reduced inequality, although the poor were also negatively affected. The evidence also suggests that the ability to use assets as a coping mechanism was limited. In a context of limited safety nets and government interventions, stringent lockdown policies appear to increase the vulnerability of the poor.

Publication The Future of Poverty(Washington, DC: World Bank, 2025-07-15)Climate change is increasingly acknowledged as a critical issue with far-reaching socioeconomic implications that extend well beyond environmental concerns. Among the most pressing challenges is its impact on global poverty. This paper projects the potential impacts of unmitigated climate change on global poverty rates between 2023 and 2050. Building on a study that provided a detailed analysis of how temperature changes affect economic productivity, this paper integrates those findings with binned data from 217 countries, sourced from the World Bank’s Poverty and Inequality Platform. By simulating poverty rates and the number of poor under two climate change scenarios, the paper uncovers some alarming trends. One of the primary findings is that the number of people living in extreme poverty worldwide could be nearly doubled due to climate change. In all scenarios, Sub-Saharan Africa is projected to bear the brunt, contributing the largest number of poor people, with estimates ranging between 40.5 million and 73.5 million by 2050. Another significant finding is the disproportionate impact of inequality on poverty. Even small increases in inequality can lead to substantial rises in poverty levels. For instance, if every country’s Gini coefficient increases by just 1 percent between 2022 and 2050, an additional 8.8 million people could be pushed below the international poverty line by 2050. In a more extreme scenario, where every country’s Gini coefficient increases by 10 percent between 2022 and 2050, the number of people falling into poverty could rise by an additional 148.8 million relative to the baseline scenario. These findings underscore the urgent need for comprehensive climate policies that not only mitigate environmental impacts but also address socioeconomic vulnerabilities.Publication Exports, Labor Markets, and the Environment(Washington, DC: World Bank, 2025-07-14)What is the environmental impact of exports? Focusing on 2000–20, this paper combines customs, administrative, and census microdata to estimate employment elasticities with respect to exports. The findings show that municipalities that faced increased exports experienced faster growth in formal employment. The elasticities were 0.25 on impact, peaked at 0.4, and remained positive and significant even 10 years after the shock, pointing to a long and protracted labor market adjustment. In the long run, informal employment responds negatively to export shocks. Using a granular taxonomy for economic activities based on their environmental impact, the paper documents that environmentally risky activities have a larger share of employment than environmentally sustainable ones, and that the relationship between these activities and exports is nuanced. Over the short run, environmentally risky employment responds more strongly to exports relative to environmentally sustainable employment. However, over the long run, this pattern reverses, as the impact of exports on environmentally sustainable employment is more persistent.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 The Asymmetric Bank Distress Amplifier of Recessions(Washington, DC: World Bank, 2025-07-11)One defining feature of financial crises, evident in U.S. and international data, is asymmetric bank distress—concentrated losses on a subset of banks. This paper proposes a model in which shocks to borrowers’ productivity dispersion lead to asymmetric bank losses. The framework exhibits a “bank distress amplifier,” exacerbating economic downturns by causing costly bank failures and raising uncertainty about the solvency of banks, thereby pushing banks to deleverage. Quantitative analysis shows that the bank distress amplifier doubles investment decline and increases the spread by 2.5 times during the Great Recession compared to a standard financial accelerator model. The mechanism helps explain how a seemingly small shock can sometimes trigger a large crisis.Publication Impact of Heat Waves on Learning Outcomes and the Role of Conditional Cash Transfers(Washington, DC: World Bank, 2025-07-14)This paper evaluates the impact of higher temperatures on learning outcomes in Peru. The results suggest that 1 degree above 20°C is equivalent to 7 and 6 percent of a standard deviation of what a student learns in a year for math and reading tests, respectively. These results hold true when the main specification is changed, splitting the sample, collapsing the data at school level, and using other climate specifications. The paper aims to improve understanding of how to deal with the impacts of climate change on learning outcomes in developing countries. The evidence suggests that conditional cash transfer programs can mitigate the negative effects of higher temperatures on students’ learning outcomes in math and reading.

Publication Impacts of COVID-19 on Household Welfare in Tunisia(World Bank, Washington, DC, 2020-12)COVID-19 is likely to have a large impact on the welfare of Tunisian households. First, some individuals might be more vulnerable to contracting the disease because their living conditions or jobs make them more susceptible to meeting others or practicing social distancing. Lack of adequate access to health insurance, overcrowded living conditions, and low access to water at home are reasons that make the Tunisian poor more susceptible to getting infected or not being able to seek health care in the event that they contract COVID-19. In addition, the elderly in the poorest households could be more susceptible to COVID-19 due to higher prevalence of intergenerational households among the poor. Second, many sectors of the labor market have experienced an economic slowdown, and those employed in these sectors are likely to experience disproportionate effects. Combining the labor shock and price shock simultaneously, the simulations in this paper show an increase in poverty of 7.3 percentage points under a more optimistic scenario and 11.9 percentage points under the pessimistic scenario, and individuals in sectors such as tourism and construction are expected to fall into poverty due to COVID-19. The paper estimates that the government’s compensatory measures targeted toward the hardest hit are expected to mitigate the increase in poverty. Specifically, the increase in poverty will be 6.5 percentage points under the optimistic scenario if mitigation measures are in place vis-à-vis in their absence, when the increase in poverty is 7.3 percentage points.Publication Scaling up Aid or Scaling down : The Global Economic Crisis and Rwanda’s MDGs(2009-06-01)Rwanda is not on track to achieve most of the Millennium Development Goals at a time when hopes for scaled-up aid are mixed with concerns that, in the context of the global economic crisis, aid instead will be scaled down. This paper analyzes the effects of alternative scenarios for grant aid, government spending allocations (between infrastructure, agriculture, and human development), and government efficiency. The authors use an economy-wide model for development strategy analysis, Maquette for Millennium Development Goal Simulations. Under a plausible scenario for increased aid, annual growth in gross domestic product increases by as much as 0.6 percentage points relative to a baseline with a growth rate of 6 percent; by 2020, the headcount poverty rate declines to 32 percent, 3 percentage points lower than for the baseline. A plausible scenario for reduced aid leads to a symmetric growth reduction but a more pronounced increase in poverty, at 40 percent in 2020. When aid increases, the most positive growth and poverty reduction impacts occur if spending increases are allocated to infrastructure and agriculture; progress in human health and education is significant but weaker than if additional spending is focused on these areas. Given synergies and diminishing marginal returns from expansion in a limited area, the scenarios that may appear most attractive and politically feasible have a broad and balanced expansion across government functions, promoting both growth and human development.Publication The Patterns and Determinants of Household Welfare Growth in Jordan : 2002-2010(World Bank, Washington, DC, 2012-10)Jordan's economic growth in the past decade has translated into a significant rise in household consumption and a decline in poverty and inequality indicators. Yet, the sentiment of the overall population seems to point to worsening disparities. Using official household expenditure surveys for 2002, 2008, and 2010, this paper analyzes the patterns and determinants of household welfare growth and examines the extent to which economic growth has been inclusive of the more vulnerable groups. Using counterfactual decompositions, the paper dwells first on the dynamics observed behind the drop in poverty and inequality. It then carries out regression analysis using re-centered influence functions to examine the economic determinants of household welfare growth throughout the decade. The paper finds that welfare growth as opposed to welfare distribution was the main driver behind poverty reduction, and that the drop in inequality was primarily driven by a regional catching-up effect. In addition, the analysis identifies rent, access to human capital services, and more importantly employment in the services sector and the public sector as the major determinants of welfare growth in Jordan. Public hiring in particular was used extensively as a tool for poverty alleviation, especially for residents outside the capital.Publication The Distributional Impacts of Indonesia's Financial Crisis on Household Welfare : A 'Rapid Response' Methodology(Washington, DC: World Bank, 2002-09)Analyzing the distributional impacts of economic crises is an ever more pressing need. If policymakers are to intervene to help those most adversely affected, they need to identify those who have been hurt most and estimate the magnitude of the harm they have suffered. They must also respond in a timely manner. This article develops a simple methodology for measuring these effects and applies it to analyze the impact of the Indonesian economic crisis on household welfare. Using only pre-crisis household information, it estimates the compensating variation for Indonesian households following the 1997 Asian currency crisis and then explores the results with flexible nonparametric methods. It finds that virtually every household was severely affected, although the urban poor fared the worst. The ability of poor rural households to produce food mitigated the worst consequences of the high inflation. The distributional consequences are the same whether or not households are permitted to substitute toward relatively cheaper goods. Households with young children may have suffered disproportionately large adverse effects.Publication Monitoring the Socio-Economic Impacts of COVID-19 on Djiboutian Households(World Bank, Washington, DC, 2020-09)Djibouti had its first confirmed case of Coronavirus (COVID-19) on 18 March 2020. As an early response, the government suspended all in and out international passenger flights on March 18, 2020, closed schools and universities, and ordered a general lockdown starting from March 27, 2020. As of August 20, 2020, there were 5,374 confirmed cases of Coronavirus (COVID-19) in Djibouti, with fifty-nine reported deaths. Even though the total number of cases increased sharply in the last two weeks of May and early June, they declined considerably in July and August. This report focuses on the Coronavirus (COVID-19) impacts on households in Djibouti as of September 2020.

Publication World Development Report 2022(Washington, DC: World Bank, 2022-02-15)World Development Report 2022: Finance for an Equitable Recovery examines the central role of finance in the economic recovery from COVID-19. Based on an in-depth look at the consequences of the crisis most likely to affect low- and middle-income economies, it advocates a set of policies and measures to mitigate the interconnected economic risks stemming from the pandemic—risks that may become more acute as stimulus measures are withdrawn at both the domestic and global levels. Those policies include the efficient and transparent management of nonperforming loans to mitigate threats to financial stability, insolvency reforms to allow for the orderly reduction of unsustainable debts, innovations in risk management and lending models to ensure continued access to credit for households and businesses, and improvements in sovereign debt management to preserve the ability of governments to support an equitable recovery.Publication Global Economic Prospects, January 2023(Washington, DC: World Bank, 2023-01-10)Global growth is projected to decelerate sharply, reflecting synchronous policy tightening aimed at containing very high inflation, worsening financial conditions, and continued disruptions from Russia’s invasion of Ukraine. Investment growth in emerging market and developing economies (EMDEs) is expected to remain below its average rate of the past two decades. Further adverse shocks could push the global economy into recession. Small states are especially vulnerable to such shocks because of the reliance on external trade and financing, limited economic diversification, elevated debt, and susceptibility to natural disasters. Against this backdrop, it is critical that EMDE policy makers ensure that any fiscal support is focused on vulnerable groups, that inflation expectations remain well anchored, and that financial systems continue to be resilient. Urgent global and national efforts are also needed to mitigate the risks of global recession and debt distress in EMDEs, and to support a major increase in EMDE investment.Publication Digital Opportunities in African Businesses(Washington, DC: World Bank, 2024-05-16)Adoption of digital technologies is widely acknowledged to boost productivity and employment, stimulate investment, and promote growth and development. Africa has already benefited from a rapid diffusion of information and communications technology, characterized by the widespread adoption of mobile phones. However, access to and use of digital technology among firms is uneven in the region, varying not just among countries but also within them. Consequently, African businesses may not be reaping the full potential benefits offered by ongoing improvements in digital infrastructure. Using rich datasets, “Digital Opportunities in African Businesses” offers a new understanding of the region’s incomplete digitalization—namely, shortfalls in the adoption and effective use of digital technology by firms to perform productive tasks. The research presented here also highlights the challenges in addressing incomplete digitalization, finding that the cost of machinery, equipment, and software, as well as the cost of connectivity to the internet, is significantly more expensive in Africa than elsewhere. “Digital Opportunities in African Businesses” outlines ways in which the private sector, with support from policy makers, international institutions, and regulators, can help bring down these costs, stimulating more widespread digitalization of the region’s firms, thereby boosting productivity and, by extension, economic development. This book will be relevant to anyone with an interest in furthering digitalization across Africa.Publication Women, Business and the Law 2023(Washington, DC: World Bank, 2023-03-02)“Women, Business and the Law 2023” is the ninth in a series of annual studies measuring the laws and regulations that affect women’s economic opportunity in 190 economies. The project presents eight indicators structured around women’s interactions with the law as they move through their lives and careers: Mobility, Workplace, Pay, Marriage, Parenthood, Entrepreneurship, Assets, and Pension. The 2023 edition identifies barriers to women’s economic participation and encourages reform of discriminatory laws. This year, the study also includes research, a literature review, and analysis of 53 years of reforms for women’s rights. Examining the economic decisions that women make throughout their working lives as well as tracking regulatory changes from 1970 to today, the study makes an important contribution to research and policy discussions about the state of women’s economic opportunities. By presenting powerful examples of change and highlighting the gaps still remaining, “Women, Business and the Law 2023” is a vital tool in ensuring economic empowerment for all. Data in “Women, Business and the Law 2023” are current as of October 1, 2022.Publication World Bank Group Climate Change Action Plan 2021–2025(World Bank, Washington, DC, 2021-06-22)Update 2025: The World Bank Group Climate Change Action Plan (CCAP) has been extended until June 30, 2026, with no other changes. The Climate Change Action Plan 2021–2025 aims to advance the climate change aspects of the WBG’s Green, Resilient, and Inclusive Development (GRID) approach, which pursues poverty eradication and shared prosperity with a sustainability lens. In the Action Plan, we will support countries and private sector clients to maximize the impact of climate finance, aiming for measurable improvements in adaptation and resilience and measurable reductions in GHG emissions. The Action Plan also considers the vital importance of natural capital, biodiversity, and ecosystems services and will increase support for nature-based solutions, given their importance for both mitigation and adaptation. As part of our effort to drive climate action, the WBG has a long-standing record of participating in key partnerships and high-level forums aimed at enhancing global efforts to address climate change. The new Action Plan represents a shift from efforts to “green” projects, to greening entire economies, and from focusing on inputs, to focusing on impacts. It focuses on (i) integrating climate and development; (ii) identifying and prioritizing action on the largest mitigation and adaptation opportunities; and (iii) using those to drive our climate finance and leverage private capital in ways that deliver the most results. That means helping the largest emitters flatten the emissions curve and accelerate the downward trend and ramping up financing on adaptation to help countries and private sector clients prepare for and adapt to climate change while pursuing broader development objectives through the GRID approach.
