Abstract
Using 40 years of historical rainfall data, this paper estimates a distribution for payouts on rainfall insurance policies offered to farmers in the State of Andhra Pradesh, India, in 2006. The authors find that the contracts primarily protect households against extreme tail events; half the expected value of indemnities paid by the insurance are generated by only 2 percent of rainfall realizations. Contract payouts are significantly correlated cross-sectionally, and also inversely associated with real GDP growth. The paper discusses the implications of these findings for the potential benefits of insurance to households, the risks facing a financial institution underwriting rainfall insurance contracts, and pricing.

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 Barriers to Household Risk Management : Evidence from India(2010-12-01)Why do many households remain exposed to large exogenous sources of non-systematic income risk? This paper uses a series of randomized field experiments in rural India to test the importance of price and non-price factors in the adoption of an innovative rainfall insurance product. The analysis finds that demand is significantly price-elastic, but that even if insurance were offered with payout ratios similar to US, widespread coverage would not be achieved. The paper identifies key non-price frictions that limit demand: liquidity constraints, particularly among poor households, lack of trust, and limited salience. The authors suggest potential improvements in contract design to mitigate these frictions.Publication Microinsurance : A Case Study of the Indian Rainfall Index Insurance Market(2010-10-01)Rainfall index insurance provides a payout based on measured local rainfall during key phases of the agricultural season, and in principle can help rural households diversify a key source of idiosyncratic risk. This paper describes basic features of rainfall insurance contracts offered in India since 2003, and documents stylized facts about market demand and the distribution of payouts. The authors summarize the results of previous research on this market, which provides evidence that price, liquidity constraints, and trust all present significant barriers to increased take-up. They also discuss potential future prospects for rainfall insurance and other index insurance products.Publication The Mechanics and Regulation of Variable Payout Annuities(2011-08-01)This paper discusses the mechanics and regulation of participating and unit-linked variable payout annuities. These annuities offer benefits that are not fixed in either nominal or real terms but depend on the performance of the fund or funds in which the underlying reserve assets are invested, their profit sharing features, and the treatment of longevity risk. The paper focuses on the treatment of investment and longevity risks by different types of these annuities and underscores the challenge of establishing a robust and effective framework of regulation and supervision for these products. The paper also addresses the exposure of annuitants to integrity risk and places special emphasis on the need for a high level of meaningful transparency.Publication Patterns of Rainfall Insurance Participation in Rural India(World Bank, Washington, DC, 2007-11)This paper describes the contract design and institutional features of an innovative rainfall insurance policy offered to smallholder farmers in rural India, and presents preliminary evidence on the determinants of insurance participation. Insurance takeup is found to be decreasing in basis risk between insurance payouts and income fluctuations, increasing in household wealth and decreasing in the extent to which credit constraints bind. These results match with predictions of a simple neoclassical model appended with borrowing constraints. Other patterns are less consistent with the "benchmark" model; namely, participation in village networks and measures of familiarity with the insurance vendor are strongly correlated with insurance takeup decisions, and risk-averse households are found to be less, not more, likely to purchase insurance. We suggest that these results reflect household uncertainty about the product itself, given their limited experience with it.Publication Designing the Payout Phase of Funded Pension Pillars in Central and Eastern European Countries(2010-04-01)Over the past decade or so, most Central and Eastern European countries have reformed their pension systems, significantly downsizing their public pillars and creating private pillars based on capitalization accounts. Early policy attention was focused on the accumulation phase but several countries are now reaching the stage where they need to address the design of the payout phase. This paper reviews the complex policy issues that will confront policymakers in this effort and summarizes recent plans and developments in four countries (Poland, Hungary, Estonia, and Lithuania). The paper concludes by highlighting a number of options that merit detailed consideration.

Publication Taxes, Spending, and Equity: International Patterns and Lessons for Developing Countries(Washington, DC: World Bank, 2025-11-17)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.Publication Data Transparency and GDP Growth Forecast Errors(World Bank, Washington, DC, 2023-04-19)This paper examines the role of a country’s data transparency in explaining gross domestic product growth forecast errors. It reports four sets of results that have not been previously reported in the existing literature. First, forecast errors—the difference between forecasted and realized gross domestic product growth—are large. Globally, between 2010 and 2020, the average same-year forecast error was 1.3 percentage points for the World Bank’s forecasts published in January of each year, and 1.5 percentage points for the International Monetary Fund’s January forecasts. Second, the Middle East and North Africa region has the largest forecast errors compared to other regions. Third, data capacity and transparency significantly explain forecast errors. On average, an improvement in a country’s Statistical Capacity Index, a measure of data capacity and transparency, is associated with a decline in absolute forecast errors. A one standard deviation increase in the log of the Statistical Capacity Index is associated with a decline in absolute forecast errors by 0.44 percentage point for World Bank forecasts and 0.49 percentage point for International Monetary Fund forecasts. The results are robust to a battery of control variables and robustness checks. Fourth, the role of the overall data ecosystem, not just those elements related to gross domestic product growth forecasting, is important for the accuracy of gross domestic product growth forecasts. Finally, gross domestic product growth forecasts from the World Bank are more accurate and less optimistic than those from the International Monetary Fund and the private sector.Publication World Development Report 2007(World Bank, 2006)The theme of The World Development Report 2007 is youth - young people between the ages of 12 to 24. As this population group seeks identity and independence, they make decisions that affect not only their own well-being, but that of others, and they do this in a rapidly changing demographic and socio-economic environment. Supporting young people's transition to adulthood poses important opportunities and risky challenges for development policy. Are education systems preparing young people to cope with the demands of changing economies? What kind of support do they get as they enter the labor market? Can they move freely to where the jobs are? What can be done to help them avoid serious consequences of risky behavior, such as death from HIV-AIDS and drug abuse? Can their creative energy be directed productively to support development thinking? The report will focus on crucial capabilities and transitions in a young person's life: learning for life and work, staying healthy, working, forming families, and exercising citizenship. For each, there are opportunities and risks; for all, policies and institutions matter.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 Nigeria Development Update - Staying the Course(Washington, DC: World Bank, 2024-11-13)The Nigeria Development Update (NDU) is a World Bank report series produced twice a year that assesses recent economic and social developments and prospects in Nigeria, and places these in a longer-term and global context. The NDU also provides an in-depth examination of selected policy issues and medium-term development challenges in Nigeria. It is intended for a wide audience, including policy makers, business leaders, financial market participants, and the community of analysts and professionals engaged in Nigeria’s evolving economy
