Abstract
Multidimensional poverty comparisons can be sensitive to the choice of welfare indicators, the weights assigned to the indicators, as well as the aggregate poverty measure used. This paper examines the robustness of trends in multidimensional poverty in the Philippines to these choices by presenting estimates for three alternative weighting schemes and three measures of multidimensional poverty. The weighting schemes range from uniform weights similar to those used in the global multidimensional poverty indexes produced by the United Nations Development Programme, to weights based on inverse incidence of different deprivations and those derived from the estimated relationship of deprivations to a survey-based measure of subjective welfare. The multidimensional poverty measures similarly range from the "dual cut-off" indexes analogous to the United Nations Development Programme's global Multidimensional Poverty Index, to “union-based” indexes that count all deprivations, to indexes that are also responsive to the distribution of deprivations. Using data for 2004-13, the paper finds evidence of a significant decline in multidimensional poverty that is robust to these alternatives, although the magnitude of the decline in, and especially the dimensional contributions to, aggregate multidimensional poverty are quite sensitive to the alternatives considered.

Publication Climate and Social Sustainability in Fragility, Conflict, and Violence Contexts(Washington, DC: World Bank, 2026-01-07)Climate change is widely recognized as a driver of violent conflict, but its broader social effects remain less understood. Ignoring these dimensions risks a vicious cycle where climate policies might undermine socially just adaptation. Evidence is still limited on how climate shocks influence political participation, trust, or migration. This paper helps fill that gap by examining links between climate change, conflict, and social sustainability, with a focus on inclusion, resilience, cohesion, and legitimacy. Using secondary data from 2019–24, the study applies simple correlation-based methods to test three hypotheses on the nature, severity, and composition of these associations. The analysis combines multiple climate impact measures, new conflict classifications, recent social sustainability frameworks, and controls for population and geography. The results reveal strong correlations—not causation—between climate events and contexts of fragility, conflict, and violence. Climate impacts are most pronounced in both national and subnational conflict settings. The study also finds robust links between fragility, conflict, and violence and low levels of social sustainability, reflecting its role as both a driver and consequence of conflict. Some dimensions—such as violent events and insecurity—appear weaker in areas most affected by climate shocks. Two of the hypotheses are supported, and one remains inconclusive.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 Institutional Capacity for Policy Implementation: An Analytical Framework(Washington, DC: World Bank, 2026-01-07)State capacity is an important prerequisite for policy implementation, yet at the country level it is difficult to measure, assess, and reform. This paper proposes a focus on institutional capacity: the ability of public institutions to implement the specific policy mandates for which they are responsible. Based on a review of existing literature, the paper defines the different dimensions that compose institutional capacity and groups them into two cross-cutting categories: organizational dimensions (personnel, financial resources, information systems, and management practices) and governance dimensions (transparency, independence, and accountability). The paper proposes measures for organizational and governance dimensions using existing data, shows intra-institutional variation of these measures within countries, and discusses how new data could be collected for better measurement of these concepts. Finally, the paper illustrates how the framework can be used to diagnose the sources of common problems related to weak policy implementation.Publication South Africa’s Fragmented Cities: The Unequal Burden of Labor Market Frictions(Washington, DC: World Bank, 2026-01-08)Using high-resolution administrative, census, and satellite data, this paper shows that South African cities are characterized by spatial mismatches between where people live and where jobs are located, relative to 20 global peers. Areas within 5 kilometers of commercial centers have 9,300 fewer residents per square kilometer than expected, which is 60 percent below the global median. Poor, dense neighborhoods are most affected. In Johannesburg, a 10-percentile increase in distance from the nearest business hub corresponds to a 3.7-percentile drop in asset wealth (a proxy of household wellbeing) and 4.9-percentile drop in employment. In Cape Town, the declines are 4.0 and 3.7 percentiles, respectively. Employment is 87 percent lower in the poorest decile than the richest in Johannesburg and 61 percent lower in Cape Town. These findings suggest that South Africa’s spatial organization of people and economic activity constrains agglomeration and reinforces inequality. This methodology provides a scalable and standardized data-driven framework to analyze spatial accessibility and agglomeration frictions in complex, data-constrained urban systems.Publication Investment in Emerging and Developing Economies(Washington, DC: World Bank, 2026-01-07)The world faces a pressing challenge to meet key development objectives amid slowing growth and rising macroeconomic and geopolitical risks. With the number of job seekers rising rapidly, infrastructure shortfalls continuing to be large, and climate costs mounting, the case for a significant investment push has never been stronger. Yet the capacity to respond in many emerging markets and developing economies has eroded. Since the global financial crisis, investment growth has slowed to about half its pace in the 2000s, with both public and private investment weakening. Foreign direct investment inflows—a critical source of capital, technology, and managerial know-how—have also fallen sharply and become increasingly concentrated, leaving low-income countries with only a marginal share. The risks of further retrenchment are significant, as trade tensions, policy uncertainty, and elevated debt levels continue to weigh on investment. Reigniting momentum will require ambitious domestic reforms to strengthen institutions, rebuild macro-fiscal stability, and deepen trade and investment integration—the foundations of a supportive business climate. At the same time, international cooperation is indispensable. A renewed commitment to a predictable system of cross-border trade and investment flows, combined with scaled-up financial support and sustained technical assistance, is essential to help emerging markets and developing economies—especially low-income countries and economies in fragile and conflict situations—bridge financing gaps and implement the domestic reforms needed to restore investment as an engine of growth, jobs, and development.

Publication Distribution-Sensitive Multidimensional Poverty Measures(Published by Oxford University Press on behalf of the World Bank, 2019-10)This paper presents axiomatic arguments to make the case for distribution-sensitive multidimensional poverty measures. The commonly used counting measures violate the strong transfer axiom, which requires regressive transfers to be unambiguously poverty increasing, and they are also invariant to changes in the distribution of a given set of deprivations among the poor. The paper appeals to strong transfer as well as an additional cross-dimensional convexity property to offer axiomatic justification for distribution-sensitive multidimensional poverty measures. Given the nonlinear structure of these measures, it is also shown how the problem of an exact dimensional decomposition can be solved using Shapley decomposition methods to assess dimensional contributions to poverty. An empirical illustration for India highlights distinctive features of the distribution-sensitive measures.Publication Distribution-Sensitive Multidimensional Poverty Measures(World Bank, Washington, DC, 2018-02)This paper presents axiomatic arguments to make the case for distribution-sensitive multidimensional poverty measures.

Crisis, Poverty, and Income Distribution in the Philippines(World Bank, Washington, DC, 2000-10)Using household survey data for 1998, the authors assess the distributional impact of the recent economic crisis in the Philippines. The results suggest that the impact of the crisis was modest, leading to a five percent reduction in average living standards, and a nine percent increase in the incidence of poverty - with larger increases indicated for the depth, and severity of poverty. The greater shock came from El Nino, rather than through the labor market. The labor market shock was progressive (reducing inequality) while El Nino shock was regressive (increasing inequality). Not all households were equally vulnerable to the crisis-induced shocks. Household and community characteristics affected the impact of the shocks. Ownership of land, made households more susceptible to the El Nino shocks, higher levels of education made households more vulnerable to wage, and employment shocks. The impact of the crisis was greater in more commercially developed communities. Occupational diversity within a household helped mitigate the adverse impact. There is some evidence of consumption smoothing by the households affected by the crisis, but the poor were less able to protect their consumption, which is a matter of policy concern.Publication Growth, Urbanization, and Poverty Reduction in India(World Bank, Washington, DC, 2016-02)Longstanding development issues are revisited in the light of a newly-constructed data set of poverty measures for India spanning 60 years, including 20 years since reforms began in earnest in 1991. The study finds a downward trend in poverty measures since 1970, with an acceleration post-1991, despite rising inequality. Faster poverty decline came with higher growth and a more pro-poor pattern of growth. Post-1991 data suggest stronger inter-sectoral linkages: urban consumption growth brought gains to the rural as well as the urban poor, and the primary-secondary-tertiary composition of growth has ceased to matter, as all three sectors contributed to poverty reduction.Publication Has India’s Economic Growth Become More Pro-Poor in the Wake of Economic Reforms?(2009-10-01)The extent to which India's poor have benefited from the country s economic growth has long been debated. This paper revisits the issues using a new series of consumption-based poverty measures spanning 50 years, and including a 15-year period after economic reforms began in earnest in the early 1990s. Growth has tended to reduce poverty, including in the post-reform period. There is no robust evidence that the responsiveness of poverty to growth has increased, or decreased, since the reforms began, although there are signs of rising inequality. The impact of growth is higher for poverty measures that reflect distribution below the poverty line, and it is higher using growth rates calculated from household surveys than national accounts. The urban-rural pattern of growth matters to the pace of poverty reduction. However, in marked contrast to the pre-reform period, the post-reform process of urban economic growth has brought significant gains to the rural poor as well as the urban poor.

Publication Ukraine Country Environmental Analysis(World Bank, Washington, DC, 2016-01)The objective of the Country Environmental Analysis (CEA) is to assess the adequacy and performance of the policy, legal, and institutional framework for environmental management in Ukraine, in light of the decentralization process of environmental governance and wider reform objectives, and to provide recommendations to government to address the key gaps identified. Ukraine is the second largest country in Europe and has a population of 43 million, the majority of whom live in urban areas. It is a lower middle income country, with the services, industry and agriculture sectors being main contributors to the country’s Gross Domestic Product (GDP). Ukraine faces a number of environmental challenges, as identified in its National Environmental Strategy 2020 (NES). Key among these are: air pollution; quality of water resources and land degradation; solid waste management; biodiversity loss; human health issues associated with environmental risk factors; in addition to climate change. The scope of Ukrainian environmental legislation is quite broad and comprehensive (more than 300 legal acts) and covers most areas of environmental protection and natural resources management. However, the environmental legislation faces a number of weaknesses:The environmental legislation is largely declaratory in nature and does not have all the essential enforcement mechanisms for the implementation of legal acts and international agreements; Many of the acts are not coordinated with each other; and Legislation undergoes limited analysis of its impact—for example, no in-depth analysis such as Regulatory Impact Analysis is conducted for proposed pieces of legislation.Publication Digital Africa(Washington, DC: World Bank, 2023-03-13)All African countries need better and more jobs for their growing populations. "Digital Africa: Technological Transformation for Jobs" shows that broader use of productivity-enhancing, digital technologies by enterprises and households is imperative to generate such jobs, including for lower-skilled people. At the same time, it can support not only countries’ short-term objective of postpandemic economic recovery but also their vision of economic transformation with more inclusive growth. These outcomes are not automatic, however. Mobile internet availability has increased throughout the continent in recent years, but Africa’s uptake gap is the highest in the world. Areas with at least 3G mobile internet service now cover 84 percent of Africa’s population, but only 22 percent uses such services. And the average African business lags in the use of smartphones and computers as well as more sophisticated digital technologies that catalyze further productivity gains. Two issues explain the usage gap: affordability of these new technologies and willingness to use them. For the 40 percent of Africans below the extreme poverty line, mobile data plans alone would cost one-third of their incomes—in addition to the price of access devices, apps, and electricity. Data plans for small- and medium-size businesses are also more expensive than in other regions. Moreover, shortcomings in the quality of internet services—and in the supply of attractive, skills-appropriate apps that promote entrepreneurship and raise earnings—dampen people’s willingness to use them. For those countries already using these technologies, the development payoffs are significant. New empirical studies for this report add to the rapidly growing evidence that mobile internet availability directly raises enterprise productivity, increases jobs, and reduces poverty throughout Africa. To realize these and other benefits more widely, Africa’s countries must implement complementary and mutually reinforcing policies to strengthen both consumers’ ability to pay and willingness to use digital technologies. These interventions must prioritize productive use to generate large numbers of inclusive jobs in a region poised to benefit from a massive, youthful workforce—one projected to become the world’s largest by the end of this century.Publication Regional Poverty and Inequality Update: Latin America and the Caribbean, October 2025(Washington, DC: World Bank, 2025-10-23)This brief summarizes recent facts related to poverty and inequality in Latin America and the Caribbean (LAC) using the latest wave of harmonized household surveys from the Socio-Economic Database for LAC (SEDLAC). This brief was produced by the Poverty Global Practice in the LAC Region of the World Bank.Publication Employment and Poverty in the Philippines(World Bank, Washington, DC, 2015-12)This study analyzes labor market performance in the Philippines from the perspective of workers’ welfare. It argues that pervasive in-work poverty is the main challenge facing labor policy. Poverty is primarily due to low earning capacity of the poor and to their limited access to regular and productive jobs. Behind these are the two interrelated root causes of in-work poverty—low education of the poor, and the scarcity of productive job opportunities. The labor market is segmented into “good” and “bad” jobs, with the poor working in the latter. They hold jobs that are informal, temporary or casual, and low-paid. Widespread informality means that the poor neither benefit from the minimum wage policy nor from employment protection legislation. They do not benefit from wage growth either, because their bargaining power is weak. “Good” jobs are so few, especially in rural areas, that even better educated workers are often forced to take unskilled jobs and work as low-paid laborers. The reduction of in-work poverty hinges on removing constraints to gainful employment in both supply side (better education and skills) and demand side (better jobs). It is critical that the young poor have improved access to quality education, and be equipped with skills required in the modern sector of the economy. But in parallel, better jobs need to be created, which can be attained from the growth of the formal and higher value added sector of the economy. The process of structural transformation should be supported by effective labor policy. Labor regulations need to be made simpler and more flexible to facilitate the reallocation of labor from less to more productive activities, and from informal to formal sector. Targeted training programs have the potential to address the problem of low skills among the poor workers, especially the young ones. Such programs should be developed on a pilot basis and expanded if proven to be cost-effective.Publication Thailand Monthly Economic Monitor, October 2025(Washington, DC: World Bank, 2025-10-22)Fiscal conditions remained stable, with a modest widening of the deficit to 3.1 percent of GDP. New stimulus measures are expected to support short-term demand without breaching the public debt ceiling. Inflation stayed negative, reflecting lower energy and food prices amid subdued domestic demand. The central bank kept the policy rate unchanged, citing limited policy space. Thailand’s growth momentum has slowed further as manufacturing activity and services weakened as projected. Tourism remained subdued, largely due to fewer Chinese visitors. Goods exports also slowed as earlier front-loaded orders faded, particularly in agriculture and industrial goods. The Thai baht depreciated in early October as the US dollar appreciated and the current account turned negative.
