Abstract
Multidimensional poverty measures can in theory make well-being comparisons that are less biased than those solely based on monetary poverty. However, global multidimensional poverty measures suffer in practice from limitations that have led to credible criticisms. This paper presents the case for multidimensional poverty measures, two criticisms against their current implementations, as well as recently proposed solutions to improve on these criticisms. The paper develops a method for implementing these solutions in practice. The resulting well-being indicator is used to compare well-being across Nigerian states in 2019. This empirical illustration suggests that these solutions may substantially affect well-being comparisons. The paper also quantifies the potential bias inherent to comparing well-being solely based on monetary poverty. The results find substantially different well-being comparisons between the proposed well-being indicator and monetary poverty even though monetary poverty was (i) high in Nigeria in 2019 and (ii) very heterogeneously distributed across Nigerian states; and (iii) is integrated as one component of the proposed well-being indicator. The paper aims to improve global multidimensional poverty measures by making them more consistent with preference theory and by incorporating the direct impact of mortality, which deprives individuals of the most important functioning.

Publication Geopolitics and the World Trading System(Washington, DC: World Bank, 2024-12-23)Until the beginning of this century, the GATT/WTO system worked. Economic research provided a compelling explanation. It showed that if governments maximize the well-being of their own countries broadly defined, GATT/WTO principles would facilitate mutually beneficial cooperation over their trade policy choices. Now heightened geopolitical rivalry seems to have undermined the WTO. A simple transposition of the previous rationalization suggests that geopolitics and trade cooperation are not compatible. The paper shows that this is only true if rivalry eclipses any consideration of own-country well-being. In all other circumstances, there are gains from trade cooperation even with geopolitics. Furthermore, the WTO’s relevance is in question only if it adheres too rigidly to its existing rules and norms. Through measured adaptation to the geopolitical imperative, the WTO can continue to thrive as a forum for multilateral trade cooperation in the age of geopolitics.Publication Tradeoffs over Rate Cycles(Washington, DC: World Bank, 2025-05-23)Central banks often face tradeoffs in how their monetary policy decisions impact economic activity (including employment), inflation and the price level. This paper assesses how these tradeoffs have evolved over time and varied across countries, with a focus on understanding the post-pandemic adjustment. To make these comparisons, we compile a cross-country, historical database of “rate cycles” (i.e., easing and tightening phases for monetary policy) for 24 advanced economies from 1970 through 2024. This allows us to quantify the characteristics of interest rate adjustments and corresponding macroeconomic outcomes and tradeoffs. We also calculate Sacrifice Ratios (output losses per inflation reduction) and document a historically low “sacrifice” during the post-pandemic tightening. This popular measure, however, ignores adjustments in the price level—which increased by more after the pandemic than over the past four decades. A series of regressions and simulations suggest monetary policy (and particularly the timing and aggressiveness of rate hikes) play a meaningful role in explaining these tradeoffs and how adjustments occur during tightening phases. Central bank credibility is the one measure we assess that corresponds to only positive outcomes and no difficult tradeoffs.Publication Global Socio-economic Resilience to Natural Disasters(Washington, DC: World Bank, 2025-05-22)Most disaster risk assessments use damages to physical assets as their central metric, often neglecting distributional impacts and the coping and recovery capacity of affected people. To address this shortcoming, the concepts of well-being losses and socio-economic resilience—the ability to experience asset losses without a decline in well-being—have been proposed. This paper uses microsimulations to produce a global estimate of well-being losses from, and socio-economic resilience to, natural disasters, covering 132 countries. On average, each $1 in disaster-related asset losses results in well-being losses equivalent to a $2 uniform national drop in consumption, with significant variation within and across countries. The poorest income quintile within each country incurs only 9% of national asset losses but accounts for 33% of well-being losses. Compared to high-income countries, low-income countries experience 67% greater well-being losses per dollar of asset losses and require 56% more time to recover. Socio-economic resilience is uncorrelated with exposure or vulnerability to natural hazards. However, a 10 percent increase in GDP per capita is associated with a 0.9 percentage point gain in resilience, but this benefit arises indirectly—such as through higher rate of formal employment, better financial inclusion, and broader social protection coverage—rather than from higher income itself. This paper assess ten policy options and finds that socio-economic and financial interventions (such as insurance and social protection) can effectively complement asset-focused measures (e.g., construction standards) and that interventions targeting low-income populations usually have higher returns in terms of avoided well-being losses per dollar invested.Publication From Chalkboards to Chatbots(Washington, DC: World Bank, 2025-05-20)This study evaluates the impact of a program leveraging large language models for virtual tutoring in secondary education in Nigeria. Using a randomized controlled trial, the program deployed Microsoft Copilot (powered by GPT-4) to support first-year senior secondary students in English language learning over six weeks. The intervention demonstrated a significant improvement of 0.31 standard deviation on an assessment that included English topics aligned with the Nigerian curriculum, knowledge of artificial intelligence and digital skills. The effect on English, the main outcome of interest, was of 0.23 standard deviations. Cost-effectiveness analysis revealed substantial learning gains, equating to 1.5 to 2 years of ’business-as-usual’ schooling, situating the intervention among some of the most cost-effective programs to improve learning outcomes. An analysis of heterogeneous effects shows that while the program benefits students across the baseline ability distribution, the largest effects are for female students, and those with higher initial academic performance. The findings highlight that artificial intelligence-powered tutoring, when designed and used properly, can have transformative impacts in the education sector in low-resource settings.Publication Disentangling the Key Economic Channels through Which Infrastructure Affects Jobs(Washington, DC: World Bank, 2025-04-03)This paper takes stock of the literature on infrastructure and jobs published since the early 2000s, using a conceptual framework to identify the key channels through which different types of infrastructure impact jobs. Where relevant, it highlights the different approaches and findings in the cases of energy, digital, and transport infrastructure. Overall, the literature review provides strong evidence of infrastructure’s positive impact on employment, particularly for women. In the case of electricity, this impact arises from freeing time that would otherwise be spent on household tasks. Similarly, digital infrastructure, particularly mobile phone coverage, has demonstrated positive labor market effects, often driven by private sector investments rather than large public expenditures, which are typically required for other large-scale infrastructure projects. The evidence on structural transformation is also positive, with some notable exceptions, such as studies that find no significant impact on structural transformation in rural India in the cases of electricity and roads. Even with better market connections, remote areas may continue to lack economic opportunities, due to the absence of agglomeration economies and complementary inputs such as human capital. Accordingly, reducing transport costs alone may not be sufficient to drive economic transformation in rural areas. The spatial dimension of transformation is particularly relevant for transport, both internationally—by enhancing trade integration—and within countries, where economic development tends to drive firms and jobs toward urban centers, benefitting from economies scale and network effects. Turning to organizational transformation, evidence on skill bias in developing countries is more mixed than in developed countries and may vary considerably by context. Further research, especially on the possible reasons explaining the differences between developed and developing economies, is needed.

Publication Normative Indicators Combining Poverty and Mortality(World Bank, Washington, DC, 2022-05)This paper surveys the small branch of welfare economics that studies indicators combining poverty and mortality. The paper distinguishes two reasons for constructing such indicators. The first reason is to perform multidimensional well-being comparisons. For this purpose, mortality has (negative) intrinsic value. The key question relates to the trade-off that the indicator makes between poverty and mortality, that is, between the quality and quantity of life. A lifecycle utility approach suggests expressing this trade-off as the number of years spent in poverty that is deemed equivalent to one year lost to mortality. The second reason is to investigate the instrumental role that selective mortality—the fact that the poor tend to die earlier—has on the evolution of poverty measures. Then, the key question is how to define the counterfactual situation against which the instrumental impact of mortality is assessed.Publication A Welfarist Theory Unifying Monetary and Non-Monetary Poverty Measurement(World Bank, Washington, DC, 2022-06)Multidimensional poverty measures are increasingly used in practice even though they face strong criticism and generate longlasting debates. These contentions primarily find their origin in the divergence between standard poverty identification practices and a welfarist definition of the poor. This paper fills this gap by constructing a poverty measurement theory that (i) adopts a welfarist definition of the poor, (ii) acknowledges that the relevant welfare function is only partially known and (iii) encompasses both market and non-market dimensions of well-being. The theory shows that standard identification practices are not flexible enough in order to properly account for the multidimensional nature of well-being. This nature implies that an individual is poor when she experiences an extremely low outcome in some dimension or/and when she cumulates moderately low outcomes in several dimensions. The paper proposes a simple refinement that better reflects this insight. The paper uses the theory in order to provide answers to several longlasting debates. The theory provides a conceptual foundation from which practitioners may derive guidance for the many choices they face.Publication April 2022 Update to the Multidimensional Poverty Measure(World Bank, Washington, DC, 2022-05)The April 2022 update presents the 3rd edition of the World Bank’s Multidimensional Poverty Measure (MPM), based on updates to the Global Monitoring Database (GMD). The MPM is an index that captures the percentage of households in a country deprived along three dimensions of well-being – monetary poverty, education, and basic infrastructure services – to provide a more complete picture of poverty. The latest MPM data provides country estimates for 123 economies in the GMD circa 2018, revising estimates published in March 2021. Some changes reflect the availability of more recent survey data. Other changes are due to the addition of new economies to the dataset, the release of new population data, and new monetary poverty estimates. The accompanying online dashboard containing the data and results presented in this document has also been updated. The dashboard allows users to visualize MPM data and modify the weights used when aggregating the different indicators in the MPM headcount ratio.Publication Integrating Mortality into Poverty Measurement through the Poverty Adjusted Life Expectancy Index(World Bank, Washington, DC, 2022-07)Poverty measures typically do not account for mortality, resulting in counter-intuitive evaluations. The reason is that they (i) suffer from a mortality paradox and (ii) do not attribute intrinsic value to the lifespan. The paper proposes the first poverty index that always attributes a positive value to lifespan and does not suffer from the mortality paradox. This index, called the poverty-adjusted life expectancy, follows an expected lifecycle utility approach a la Harsanyi and is based on a single normative parameter that transparently captures the trade-off between poverty and mortality. This indicator can be straightforwardly generalized to account for unequal lifespans. Empirically, we show that accounting for mortality substantially changes cross-country comparisons and trends. The paper also quantifies the fraction of these comparisons that are robust to the choice of the normative parameter.Publication Multidimensional Well-Being Measurement Practices(Washington, DC: World Bank, 2024-06-12)Multidimensional well-being indicators have the potential to reduce the “bias” associated to monetary indicators. However, they face stringent data constraints. This paper studies the construction of indicators that strike a balance between (i) reliability in approximating conceptually sound well-being comparisons and (ii) simplicity of application and communication. The recommendations focus on global multidimensional poverty measures. The paper identifies three potential sources of improvements: “wasting” less data, better filtering the data, and further developing multidimensional analysis. Less information would be “wasted” by avoiding needlessly dichotomizing all the variables, using the available mortality data, and combining variables from separate surveys. To filter the data better, “equal weights” could be replaced by weights selected from external information on preferences. When the data permit, the unit of analysis should be switched from household level to individual level. Finally, multidimensional indicators should be used to help move beyond a suboptimal “dimension-by-dimension” approach to policy making.

Publication Media and Messages for Nutrition and Health(World Bank, Washington, DC, 2020-06)The Lao People’s Democratic Republic (Lao PDR) has experienced rapid and significant economic growth over the past decade. However, poor nutritional outcomes remain a concern. Rates of childhood undernutrition are particularly high in remote, rural, and upland areas. Media have the potential to play an important role in shaping health and nutrition–related behaviors and practices as well as in promoting sociocultural and economic development that might contribute to improved nutritional outcomes. This report presents the results of a media audit (MA) that was conducted to inform the development and production of mass media advocacy and communication strategies and materials with a focus on maternal and child health and nutrition that would reach the most people from the poorest communities in northern Lao PDR. Making more people aware of useful information, essential services and products and influencing them to use these effectively is the ultimate goal of mass media campaigns, and the MA measures the potential effectiveness of media efforts to reach this goal. The effectiveness of communication channels to deliver health and nutrition messages to target beneficiaries to ensure maximum reach and uptake can be viewed in terms of preferences, satisfaction, and trust. Overall, the four most accessed media channels for receiving information among communities in the study areas were village announcements, mobile phones, television, and out-of-home (OOH) media. Of the accessed media channels, the top three most preferred channels were village announcements (40 percent), television (26 percent), and mobile phones (19 percent). In terms of trust, village announcements were the most trusted source of information (64 percent), followed by mobile phones (14 percent) and television (11 percent). Hence of all the media channels, village announcements are the most preferred, have the most satisfied users, and are the most trusted source of information in study communities from four provinces in Lao PDR with some of the highest burden of childhood undernutrition.Publication Remarks at the United Nations Biodiversity Conference(World Bank, Washington, DC, 2021-10-12)World Bank Group President David Malpass discussed biodiversity and climate change being closely interlinked, with terrestrial and marine ecosystems serving as critically important carbon sinks. At the same time climate change acts as a direct driver of biodiversity and ecosystem services loss. The World Bank has financed biodiversity conservation around the world, including over 116 million hectares of Marine and Coastal Protected Areas, 10 million hectares of Terrestrial Protected Areas, and over 300 protected habitats, biological buffer zones and reserves. The COVID pandemic, biodiversity loss, climate change are all reminders of how connected we are. The recovery from this pandemic is an opportunity to put in place more effective policies, institutions, and resources to address biodiversity loss.Publication Fiscal Incidence Analysis for Kenya(World Bank, Washington, DC, 2018-06-29)Kenya has made satisfactory progress in reducing poverty and inequality in recent years. Economic growth in Kenya between 2005-06 and 2015-16 averaged around 5.3 percent, exceeding the average growth of 4.9 percent observed for Sub-Saharan Africa. This robust economic growth resulted in a reduction in poverty, whether measured by the national or international poverty line. The proportion of the population living beneath the national poverty line fell from 46.8 percent in 2005-06 to 36.1 percent in 2015-16, showing a modest improvement in the living standards of the Kenyan population. Similarly, poverty under the international poverty line of US$ 1.90 a day declined from 43.6 percent in 2005-06 to 35.6 percent in 2015-16. At this level, poverty in Kenya is below the average in sub-Saharan Africa and is amongst the lowest in the East African Community (World Bank, 2018b). However, the proportion of the population living in poverty remains comparatively high in Kenya and the rate at which growth translated into poverty reduction was lower than elsewhere. At twice the average, Kenya’s poverty rate is still high for a lower-middle income country, a group that Kenya joined only in 2015. In addition, the Kenya’s growth elasticity of poverty reduction, the percentage reduction in the poverty rate associated with a one-percent increase in mean per capita income is only 0.57, lower than in Tanzania, Ghana, or Uganda (World Bank, 2018b). This leads to the obvious question of what can be done to make economic growth more pro-poor in Kenya. This study assesses the distributional consequences of Kenya’s system of taxes and transfers, covering 60 percent of revenue and between 25 and 30 percent of government spending. The analysis of fiscal incidence and distributional consequences of Kenya’s tax and transfer system is an important input for designing pro-poor policies and potentially for influencing the rate at which economic growth translates into poverty reduction. In this study, direct taxes and transfers, indirect taxes (VAT and excise duties), as well as public health and education spending are assessed in terms of their distributional impacts. Overall, these taxes and transfers account for about 60 percent of revenue and between 25 and 30 percent of government spending.Publication Economic Recovery(World Bank, Washington, DC, 2021-04-06)World Bank Group President David Malpass spoke about the world facing major challenges, including COVID, climate change, rising poverty and inequality and growing fragility and violence in many countries. He highlighted vaccines, working closely with Gavi, WHO, and UNICEF, the World Bank has conducted over one hundred capacity assessments, many even more before vaccines were available. The World Bank Group worked to achieve a debt service suspension initiative and increased transparency in debt contracts at developing countries. The World Bank Group is finalizing a new climate change action plan, which includes a big step up in financing, building on their record climate financing over the past two years. He noted big challenges to bring all together to achieve GRID: green, resilient, and inclusive development. Janet Yellen, U.S. Secretary of the Treasury, mentioned focusing on vulnerable people during the pandemic. Kristalina Georgieva, Managing Director of the International Monetary Fund, focused on giving everyone a fair shot during a sustainable recovery. All three commented on the importance of tackling climate change.Publication Making Devolution Work for Service Delivery in Kenya(Washington, DC: World Bank, 2022-02)Kenya adopted a new constitution and began the process of devolution in 2010, ceding many formerly national responsibilities to new county governments. As an institutional response to longstanding grievances, this radical restructuring of the Kenyan state had three continuing main objectives: decentralizing political power, public sector functions, and public finances; ensuring a more equitable distribution of resources among regions; and promoting more accountable, participatory, and responsive government at all levels. The first elections under the new constitution were held in 2013 and led to the establishment of 47 new county governments. Each county government is made up of a county executive, headed by an elected governor, and an elected County Assembly that legislates and provides oversight. Making Devolution Work for Service Delivery in Kenya takes stock of how devolution has affected the delivery of basic services to Kenyan citizens nine years after the “devolution train” left the station. Whereas devolution was driven by political reform, the ensuing institutions and systems were expected to deliver greater socioeconomic equity through devolved service delivery. Jointly coordinated by the government of Kenya and the World Bank, the Making Devolution Work for Service Delivery (MDWSD) study is the first major assessment of Kenya’s devolution reform. The study provides key messages about what is working, what is not working, and what could work better to enhance service delivery based on currently available data. It provides an independent assessment of service delivery performance in five sectors: agriculture, education, health, urban services, and water services. This assessment includes an in-depth review of the main pillars of devolved service delivery: accountability, human resource management, intergovernmental finance, politics, and public financial management. In addition to its findings for the present, the MDWSD study provides recommendations on how Kenya can improve its performance in each of these pivotal areas in the future.
