Abstract
Strong boy-bias and its consequences for young and unborn girls have been widely documented for Asia. This paper considers a country in Sub-Saharan Africa and finds that parental gender preferences do affect fertility behavior and shape traditional social institutions with negative effects on adult women's health and well-being. Using individual-level data for Nigeria, the paper shows that, compared to women with first-born sons, women with first-born daughters have (and desire) more children and are less likely to use contraceptives. Women with daughters among earlier-born children are also more likely to have shorter birth intervals, a behavior medically known to increase the risk of child and maternal mortality. Moreover, they are more likely to end up in a polygynous union, to be divorced, and to be head of the household. The preference for sons is also supported by child fostering patterns in which daughters are substitutes for foster girls, while the same does not hold for sons and foster boys. These results can partly explain excess female mortality among adult women in Sub-Saharan Africa.

    Climate and Social Sustainability in Fragility, Conflict, and Violence Contexts
    (Washington, DC: World Bank, 2026-01-07) Cuesta Leiva, Jose Antonio; Huff, Connor
    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.

    The Macroeconomic Implications of Climate Change Impacts and Adaptation Options
    (Washington, DC: World Bank, 2025-05-29) Abalo, Kodzovi; Boehlert, Brent; Bui, Thanh; Burns, Andrew; Castillo, Diego; Chewpreecha, Unnada; Haider, Alexander; Hallegatte, Stephane; Jooste, Charl; McIsaac, Florent; Ruberl, Heather; Smet, Kim; Strzepek, Ken
    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.

    Institutional Capacity for Policy Implementation: An Analytical Framework
    (Washington, DC: World Bank, 2026-01-07) Kim, Galileu; Kumar, Tanu; Ramalho, Rita; Russell, Stuart
    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.

    South Africa’s Fragmented Cities: The Unequal Burden of Labor Market Frictions
    (Washington, DC: World Bank, 2026-01-08) Baez, Javier E.; Kshirsagar, Varun
    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.

    Investment in Emerging and Developing Economies
    (Washington, DC: World Bank, 2026-01-07) Adarov, Amat; Kose, M. Ayhan; Vorisek, Dana
    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.

    Why Are Adult Women Missing? Son Preference and Maternal Survival in India
    (World Bank, Washington, DC, 2014-03) Milazzo, Annamaria
    This paper is the first to show that excess mortality among adult women can be partly explained by strong preference for male children, the same cultural norm widely known to cause excess mortality before birth or at young ages. Using pooled individual-level data for India, the paper compares the age structure and anemia status of women by the sex of their first-born and uncovers several new findings. First, the share of living women with a first-born girl is a decreasing function of the women's age at the time of the survey. Second, while there are no systematic differences at the time of birth, women with a first-born girl are significantly more likely to develop anemia when young (under the age of 30) and these differences disappear for older women. Moreover, among those in the older age group, they appear to be significantly better off in terms of various predetermined characteristics. These findings are consistent with a selection effect in which maternal and adult mortality is higher for women with first-born girls, especially the poor and uneducated with limited access to health care and prenatal sex diagnostic technologies. To ensure the desired sex composition of children, these women resort to a fertility behavior medically known to increase their risk of death. The observed sex ratios for first births imply that 2.2-8.4 percent of women with first-born girls are 'missing' because of son preference between the ages of 30 and 49.

    Fertility Regulation Behaviors and Their Costs : Contraception and Unintended Pregnancies in Africa and Eastern Europe & Central Asia
    (World Bank, Washington, DC, 2007-12) Lule, Elizabeth; Singh, Susheela; Chowdhury, Sadia Afroze
    The report consists of three parts: global trends in fertility, contraceptive use and unintended pregnancies; studies of two regions (Africa and Eastern Europe/Central Asia) and two countries (Nigeria and Kazakhstan) on the costs of fertility regulation behaviors and provider attitudes towards contraceptive use. Fertility levels have declined steadily over the last three decades but the pace of decline varies among regions. Countries that have achieved a high level of contraceptive use have reached a lower fertility level. A gap continues to exist between actual and desired family size, resulting in unintended pregnancies. More than one-third of the pregnancies that occur are unintended and one in five pregnancies ends in induced abortion. Almost half of all induced abortions are unsafe, and the proportion of all abortions that are unsafe have increased during the last decade. Sixty-six percent of unintended pregnancies occur among women who are not using any method of contraception. Investing in quality family planning programs is a cost-effective way to address unmet need for contraception and reduce the risks of unsafe abortion, thereby improving maternal health. If contraception were provided to the 137 million women who lack access, maternal mortality will decline by 25-35 percent.

    Determinants of Fertility, Women's Health and Employment Behavior in Sri Lanka
    (Washington, DC, 2012-10) World Bank
    The paper analyzes the labor market during 1992-2009, the wartime years, and uses the findings to help understand implications for the labor market as the economy grows and recovers from the conflict. The analysis is primarily based on annual Labor Force Survey (LFS) data collected by the Department of Census and Statistics (DCS) between 1992 and 2009. The paper excludes the North and East from the analysis because the labor market in these provinces was functioning in atypical times, and was affected severely by the security situation. The 2006 moving out of poverty study conducted in conflict areas noted large outmigration of the better off households and the reliance on those left behind on remittances (Center for Poverty Analysis 2006). The study also found that private sector investment had largely dwindled in these provinces, and the main source of jobs was public employment. Looking ahead, over the next 15 years, demand for workers in industry is likely to increase as rebuilding and recovery in the North and East proceeds. In addition, demand for highly skilled workers to meet the needs of the expanding services sector, particularly higher-end services, will also increase. Analyzing the empirical trends using the LFS, it is clear that increasing female labor force participation, addressing high youth unemployment and its causes, and addressing the negative aspects of certain labor market regulations will be key to meeting the needs of a growing economy. The paper is organized as follows. The two sections that follow present an overview of the supply and demand side of the labor market. The next section discusses the ways in which the demographic transition could shape the labor market, particularly in terms of unemployment and earnings. This discussion is followed by three sections examining labor force participation and unemployment, job type, and earnings respectively. The last section concludes with some policy recommendations.

    Fertility Decline in Pakistan 1980-2006
    (World Bank, Washington, DC, 2010-05) World Bank
    Pakistan was selected as a case study because of its estimated 40 percent decline in fertility between 1980 and 2006. Pakistan's high fertility rate began to decline gradually after the late 1980s and has continued to fall since then, though progress has been uneven and there have been signs of a slowdown in recent years. Unlike the other four case study countries (Algeria, Botswana, Iran, and Nicaragua), the history of fertility reduction in Pakistan has not been an overwhelming success story but rather a story of challenges, partial responses, and shortcomings that offer abundant lessons for other high-fertility countries as well as planners in Pakistan.

    Fertility Decline in Algeria 1980-2006
    (World Bank, Washington, DC, 2010-05) World Bank
    Like other countries in the Middle East and North Africa region, Algeria has undergone a demographic transition. But Algeria's fertility decline defies conventional explanation. Despite inauspicious starting conditions-a high total fertility rate, reluctant policy environment, and delayed implementation of a national family planning program-Algeria has surpassed some of its neighbors in fertility reduction. Before its fertility transition, Algeria had one of the highest crude birth rates in the world, nearly 50 per 1,000. The fertility transition began in 1965-70, before any significant government support for or investment in population control or family planning and before significant external donor funding became available. Since then, profound changes in the traditional family model have led to a 64 percent decline in the total fertility rate in recent decades, from 6.76 in 1980 to 2.41 in 2006. Overall, Algeria's fertility decline is best understood in terms of changes in behavior, especially the delay in age at first marriage, the increase in contraceptive use, and-to a certain degree-the negative effects of the economic crisis manifested in the housing shortage and unemployment of young adults.

    GIL Top Policy Lessons on Empowering Adolescent Girls
    (World Bank, Washington, DC, 2020-01) World Bank
    Adolescent girls face multiple challenges that restrict their horizons, often having to make decisions about employment and their fertility at an early age, and with limited formal education opportunities. With lower levels of education than men, girls are often less equipped for work. Additionally, a plethora of expected domestic responsibilities limit their time for income-generating opportunities. A range of gender innovation lab (GIL) studies across Sub-Saharan Africa have demonstrated the potential of girls’ empowerment programs to change the life trajectories of young women even across a variety of contexts. These programs typically combine community-based girls clubs, life-skills training, vocational training, and sometimes financial literacy and microcredit access, for young women. In addition to implementation in countries such as Uganda and Tanzania, these programs have also helped create a buffer from conflict for young women in South Sudan and during the Ebola crisis in Sierra Leone - showing that they are beneficial even across fragile contexts.

    Privatization in Africa
    (World Bank, Washington, DC, 1999-04) Cambell White, Oliver C.; Bhatia, Anita
    In a way, the story of privatization in Africa reflects some of the problems which have beset many other development processes: lack of political commitment, poor design, insufficient resources, weak management, and corruption. Privatization in Africa is the outcome of a study undertaken during 1995 and 1996. Up to that time, privatization throughout the continent had been slow, with few visible results and a general feeling among observers and donors that African governments' commitment to the process was generally half-hearted. The purpose of the study was to answer three questions about privatization: (i) what has been happening? (ii) What has resulted? And (iii) what could be done to improve the process in terms of outcome. The data and analyses presented to answer these questions fill a significant gap in the published literature on privatization in Africa. The case-study countries were Benin, Burkina Faso, Ghana, Kenya, Madagascar, Nigeria, Togo, Uganda, and Zambia. The study shows that more privatization has been happening across Africa than was generally thought to be the case; but it also raises many issues about how the process has been planned and implemented. The controversy starts with why African governments have privatized. The study maintains that the evidence suggests that most governments have privatized reluctantly and not for the reasons set out in policy statements.

    Digital Africa
    (Washington, DC: World Bank, 2023-03-13) Begazo, Tania; Dutz, Mark Andrew; Blimpo, Moussa
    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.

    Direct and Indirect Impacts of Transport Mobility on Access to Jobs: Evidence from South Africa
    (Washington, DC: World Bank, 2025-11-12) Iimi, Atsushi
    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.

    Taxes, Spending, and Equity: International Patterns and Lessons for Developing Countries
    (Washington, DC: World Bank, 2025-11-17) Wai-Poi, Matthew; Sosa, Mariano; Bachas, Pierre
    Taxes and public spending underpin the basic administration of government and finance the human capital and infrastructure investments needed for economic growth. They can also have a significant and immediate impact on poverty and inequality. The question of how public finance can support longer-term growth objectives while promoting equity has become even more important in recent years, given the high fiscal deficits and debt levels most countries emerged with in the aftermath of the COVID-19 pandemic. These included the increasing cost of debt and the need to restart environmentally sustainable growth while helping households address the learning losses and other social scars caused by the pandemic. This paper examines the global evidence on which households pay which taxes and who benefits from what spending, and critically, the net effect on different households across the income distribution. The aim is to identify the patterns and lessons that emerge for designing progressive fiscal policies. A global dataset of 96 countries is assembled, spanning all regions of the world and all national income levels, grounded in the Commitment to Equity (CEQ) approach to fiscal incidence.
