Abstract
High inequality in Africa is something of a paradox: Africa should be a low-inequality continent according to the Kuznets hypothesis (because African countries are poor and agriculture-based), and also because land (the main asset) is widely shared. The author's hypothesis is that African inequality is politically determined. Yet in the empirical analysis, despite the introduction of several political variables, there is still an inequality-increasing "Africa effect" linked to ethnic fractionalization. The politics, however, may work through ethnic fractionalization, which provides an easy and secure basis for the formation of political groups. Although this is a plausible explanation, it is not fully satisfactory, and the author criticizes it in the concluding section.

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 Inequality is Bad for Growth of the Poor (But Not for That of the Rich)(World Bank Group, Washington, DC, 2014-07)The paper assesses the impact of overall inequality, as well as inequality among the poor and among the rich, on the growth rates along various percentiles of the income distribution. The analysis uses micro-census data from U.S. states covering the period from 1960 to 2010. The paper finds evidence that high levels of inequality reduce the income growth of the poor and, if anything, help the growth of the rich. When inequality is deconstructed into bottom and top inequality, the analysis finds that it is mostly top inequality that is holding back growth at the bottom.Publication Democracy and Income Inequality : An Empirical Analysis(World Bank, Washington, DC, 2001-03)Standard political economy theories suggest that democratization has a moderating effect on income inequality. But the empirical literature has failed to uncover any such robust relationship. The authors take another look at the issue. The authors argue that prevailing ideology may be an important determinant of inequality and that the democratization effect "works through" ideology. In societies that value equality highly there is less distributional conflict among income groups, so democratization may have only a negligible effect on inequality. But in societies that value equality less, democratization reduces inequality through redistribution as the poor outvote the rich. The authors' cross-country empirical analysis, covering 126 countries in 1960-98, confirms the hypothesis: ideology, as proxied by a country's dominant religion, seems to be related to inequality. In addition, while in Judeo-Christian societies increased democratization appears to lead to lower inequality, in Muslim and Confucian societies it has an insignificant effect. The authors hypothesize that Muslim and Confucian societies rely on informal transfers to reach the desired level of inequality, while Judeo-Christian societies, where family ties are weaker, use political action.Publication Reform and Inequality During the Transition : An Analysis Using Panel Household Survey Data, 1990-2005(World Bank, Washington, DC, 2008-11)Using for the first time household survey data from 26 post-Communist countries, covering the period 1990-2005, this paper examines correlates of unprecedented increases in inequality registered by most of the economies. The analysis shows, after controlling for country fixed effects and type of survey used, that economic reform is strongly negatively associated with the income share of the bottom decile, and positively with the income shares of the top two deciles. However, breaking economic reform into its component parts, the picture is more nuanced. Large-scale privatization and infrastructure reform (mostly consisting of privatization and higher fees) are responsible for the pro-inequality effect; small-scale privatization tends to raise the income shares of the bottom deciles. Acceleration in growth is also pro-rich. But democratization is strongly pro-poor, as is lower inflation. Somewhat surprisingly, the analysis finds no evidence that greater government spending as share of gross domestic income reduces inequality.Publication Does Liberté = Egalité? A Survey of the Empirical Links between Democracy and Inequality with Some Evidence on the Transition Economies(World Bank, Washington, DC, 2002-08)The effect of the distribution of political rights on income inequality has been studied both theoretically and empirically. The authors review the existing literature and, in particular, the available empirical evidence. The literature suggests that formal exclusion from the political process through restrictions on the voting franchise appears to have caused a high degree of economic inequality. And democratization in the form of franchise expansion has typically led to an expansion in redistribution, at least in the small sample of episodes studied. In a less pronounced way, albeit more emphatically compared with the ambiguous results of earlier research, recent evidence indicates an inverse relationship between other measures of democracy, based on civil liberties and political rights, and inequality. The transition experience of Eastern European countries, however, seems to some extent go against these conclusions. This opens possible new vistas for research, namely the need to incorporate the length of democratic experience and the role played by ideology and social valuesPublication Measuring Ancient Inequality(World Bank, Washington, DC, 2007-11)Is inequality largely the result of the Industrial Revolution? Or, were pre-industrial incomes and life expectancies as unequal as they are today? For want of sufficient data, these questions have not yet been answered. This paper infers inequality for 14 ancient, pre-industrial societies using what are known as social tables, stretching from the Roman Empire 14 AD, to Byzantium in 1000, to England in 1688, to Nueva España around 1790, to China in 1880 and to British India in 1947. It applies two new concepts in making those assessments - what the authors call the inequality possibility frontier and the inequality extraction ratio. Rather than simply offering measures of actual inequality, the authors compare the latter with the maximum feasible inequality (or surplus) that could have been extracted by the elite. The results, especially when compared with modern poor countries, give new insights in to the connection between inequality and economic development in the very long run.

Publication Kyrgyz Republic Country Climate and Development Report(Washington, DC: World Bank, 2025-11-03)This Country Climate and Development Report (CCDR) on the Kyrgyz Republic aims to support the country’s development goals amid a changing climate. The CCDR considers two policy scenarios up to 2050: the business-as-usual (BAU) and high-growth scenarios. As it quantifies the likely impacts of climate change on the Kyrgyz economy between now and 2050, the report highlights key government actions to best prepare for and adapt to climate impacts (referred to as “with adaptation” measures), with a particular focus on the time horizon up to 2030. The CCDR also outlines a path to net zero emissions by 2050 (referred to as “with mitigation” measures, “decarbonization,” or, simply, “net zero 2050”), highlighting associated development co-benefits.Publication Jobs in a Changing Climate: Insights from World Bank Group Country Climate and Development Reports Covering 93 Economies(Washington, DC: World Bank, 2025-11-05)The World Bank Group’s Country Climate and Development Reports (CCDRs) provide a crosscutting look at how countries’ development prospects, and the job opportunities they offer to their people, can be threatened by climate impacts and supported by climate policies. Climate change and policies affect jobs through impacts on productivity, energy and material efficiency, and physical, human, and natural capital. They can also transform employment opportunities, especially through complementary measures that help workers and firms adapt to and benefit from new technologies and production practices. Prepared by the World Bank, the International Finance Corporation (IFC), and the Multilateral Investment Guarantee Agency (MIGA), CCDRs integrate country perspectives, climate science and economic modeling, private sector information, and policy analysis to assess how countries can successfully grow and develop their economies and create jobs despite increasing climate risks and while achieving their climate objectives and commitments. Each CCDR starts from the country’s development priorities, opportunities, and challenges, and is developed in close consultation with governments, businesses, and civil society, ensuring the recommendations reflect national priorities. By combining evidence on adaptation, resilience, and emissions pathways, CCDRs highlight where climate action can reinforce development and job creation, and where targeted policies are needed to manage risks and smooth labor market transitions. Taken together, these elements can help create local jobs, ensure economic transitions are just and inclusive, and equip workers and firms to navigate the disruptions and opportunities of a changing climate and changing technologies.Publication Comoros Country Climate and Development Report(Washington, DC: World Bank, 2025-06-18)The Union of the Comoros (The Comoros) has significant vulnerability to climate change-related risks but has considerable opportunities to strengthen preparedness and resilience against these challenges. According to the Notre Dame Global Adaptation Index, the Comoros is the 29th-most vulnerable country to climate change and the 163rd most ready to adapt (out of 191). The Comoros archipelago is exposed to many natural hazards that adversely affect the country’s natural capital, people, and physical infrastructure. In 2014, the economic cost of climate-related disasters was estimated at 5.7 million dollars annually, equivalent to 9.2 percent of Gross Domestic Product (GDP). Between 2018 and 2023, as many as 11 tropical depressions or cyclones impacted the country, with Cyclone Kenneth causing the greatest damage, equivalent to 14 percent of GDP, resulting in total economic growth falling from 3.6 percent in 2018 to 1.9 percent in 2019. More than 345,000 people (40 percent of the population) were affected by the cyclone, with 185,000 people experiencing severe impacts and 12,000 people displaced. However, there is an opportunity for the country to grow more robust and shock-responsive, and to establish pre-positioned funding mechanisms to enhance future crisis response efforts. For the Comoros, adaptation and climate-resilient development are the key climate change focus areas, with the country projected to face 836 million dollars 2050 in additional costs due to climate-related impacts. Current plans to adapt to the impacts of climate change in the Comoros include efforts to improve water management, strengthen coastal protection, and develop climate-smart agriculture practices. Given the country’s reliance on its natural resource base for economic growth and mobility, protection of these resources from climate change will be essential for promoting resilient growth and development. In addition to growing the adaptive capacity of the country’s natural resource sectors, strategic economic diversification will be important to help minimize future climate impacts, and development activities will need to be undertaken in such a way as to attract low-carbon co-benefits. The Union of the Comoros is committed to addressing climate change through its Nationally Determined Contribution (NDC) and national priorities. The country’s NDC (which was revised in 2021 for a ten-year horizon) sets ambitious targets, with a goal of reducing greenhouse gas emissions by 23 percent by 2030. The country also plans to significantly increase the share of renewable energy in its energy portfolio, reaching 33 MW by 2030. This will not only promote low-carbon development but also reduce the country’s dependency on imported oil and coal, which currently make up 95 percent of the energy mix. Additionally, the Comoros has declared its intention to increase CO2 removals by 47 percent by 2030, compared to BAU.Publication Guinea-Bissau Country Climate and Development Report(Washington, DC: World Bank, 2024-10-23)Guinea-Bissau is endowed with a wealth of natural resources, with the highest natural capital per capita in West Africa (US3,874 dollars per capita), which could be leveraged for sustainable and resilient growth. However, Guinea-Bissau faces significant development hurdles, such as high poverty rates, political instability, and economic challenges, including an over-reliance on cashew nuts. Rural poverty has increased, and the nation's infrastructure, education, and health care systems are underdeveloped. Climate change poses a severe threat, potentially impacting agriculture, fisheries, and infrastructure. Without adaptation, it could lead to a significant cut in real GDP per capita (minus 7.3 percent by 2050) and increase in poverty (with up to over 200,000 additional poor by 2050, that is, 5 percent of the expected population, in the worst scenario). The country's low greenhouse gas emissions are expected to rise, mainly due to agriculture and land-use changes, with deforestation being a major contributing factor. Although Guinea-Bissau is a low emitter, it has high mitigation ambitions, targeting a 30 percent reduction in greenhouse gas emissions by 2030. The Nationally Determined Contribution outlines significant climate actions, with initiatives focused on forest conservation, sustainable agriculture, and community development. However, the country's political instability, institutional weaknesses, and limited financial resources pose challenges to implementing these climate commitments, which depend heavily on external funding. The financial sector's underdevelopment and vulnerability to external shocks limit its ability to support green investments, though reforms could enhance resilience. Guinea-Bissau must consider its climate financing as development financing and vice-versa, engage the private sector, and integrate climate goals with national development plans to ensure a sustainable future. Concessional climate financing is vital due to the underdeveloped financial sector and the government’s limited borrowing capacity. Addressing Guinea-Bissau's vulnerability to climate change and its structural issues requires a cohesive approach that integrates development and climate strategies. This could involve improving governance, diversifying the economy, protecting natural capital, developing human capital, and investing in sustainable agriculture and infrastructure. The transition to a more sustainable and inclusive development pathway that supports economic growth is possible, but requires focusing on key strategic sectors, enhancing institutional capacity, and creating the conditions to mobilize finance. As a highly vulnerable country, there are myriad needs in the different sectors; however, to be more efficient and effective, Guinea-Bissau should prioritize actions in a few sectors, especially actions on biodiversity, agriculture, and social protection. Low carbon development, especially in energy and forestry sectors, could provide cost-efficient solutions and attract climate finance, including from the private sector, which will support the overall development agenda.Publication Mongolia Country Climate and Development Report(Washington, DC: World Bank, 2024-10-22)Mongolia’s development prospects are uniquely challenged by both the impacts of climate change and the global shift toward a low-carbon economy. The country’s efforts toward decarbonization pose significant challenges given the structurally high-emission intensity of its economy. While challenging, climate action also presents Mongolia with opportunities to achieve important development benefits. The effects of climate risks and the shift away from coal will have diverse impacts across different regions, communities, and socioeconomic levels. The report assesses the critical interconnections between Mongolia’s development ambitions and climate change action and identifies ways to transition to a more economically diversified, inclusive, and resilient development path. It highlights key climate and transition risks affecting Mongolia’s future development and presents a pathway to enhance climate mitigation and adaptation. The report also makes a case for strengthening policies to enhance resilience to climate change and ensure a just transition, particularly for the most vulnerable. The report is structured as follows: section 1 gives introduction. Section 2 delves into the linkages between development and climate in Mongolia and presents model-based findings on the economic and poverty impacts of climate change under different scenarios. Section 3 covers four in-depth sectoral analyses. The first two mainly focus on adaptation to climate change in the agriculture and water sectors. The third considers prospects for the extraction sector, while the fourth sectoral analysis focuses on decarbonizing power and heat generation. Section 4 shifts the focus to how the government can boost resilience for climate-vulnerable populations. Section 5 outlines options for mobilizing private and public financing and private investments to support the green transition. Section 6 examines the existing institutional and governance structure for climate action and presents recommendations to improve its effectiveness, and section 7 concludes with a framework for prioritizing the policy actions outlined in this report.
