Abstract
Catastrophe risk models are quantitative models used to estimate probabilistic loss distributions for a specified range of assets subject to a baseline level of disaster risk. While cat risk models are used extensively by the insurance and reinsurance industry to estimate expected losses to insured assets, their ability to estimate damages outside of a narrow range of physical assets such as buildings or infrastructure is still limited. This paper first provides a brief outline of cat risk models as they currently exist, and then outlines the major econometric issues involved in incorporating research from the growing literature on the microeconomic impacts of disasters into a cat model framework. Attention is specifically drawn to issues arising from the generally low recurrence frequencies of disasters, the likely role of difficult-to-document indirect damages in influencing total disaster costs, and issues related to generalizing disaster response functions across different domains. The paper ends by noting the large discrepancy between the current state of the literature on disaster impacts on microeconomic indicators and the level needed for adequate cat risk model performance, and suggests means of closing that gap as well as potential areas for future research.

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 Advancing Disaster Risk Financing and Insurance in ASEAN Member States : Framework and Options for Implementation, Volume 2. Technical Appendices(Washington, DC, 2012-04)This report is part of a project being jointly conducted by the World Bank, the Global Facility for Disaster Reduction and Recovery (GFDRR), the Association of Southeast Asian Nations (ASEAN) Secretariat, and United Nations International Strategy for Disaster Reduction (UNISDR). It aims to provide capacity building on disaster risk financing and insurance (DRFI) in ASEAN Member States. DRFI is a relatively new topic and, therefore, training and capacity building of local stakeholders is essential. Governments must understand the benefits and the limitations of disaster risk financing and insurance as part of their comprehensive Disaster Risk Management (DRM) strategies. This report presents main findings and recommendations on DRFI in the ASEAN region. Following the World Bank disaster risk financing and insurance framework, it consists of five chapters, including this introduction. Chapter two presents a preliminary economic and fiscal risk assessment of natural disasters in ASEAN Member States. Chapter three provides an overview of the fiscal management of natural disasters currently implemented by ASEAN Member States. Chapter four reviews the state of the private catastrophe insurance markets, including property catastrophe risk insurance, agricultural insurance, and disaster micro-insurance. Chapter five identifies five main recommendations for strengthening the long-term financial and fiscal resilience of ASEAN Member States against natural disasters, as part of their broader disaster risk management and climate change adaptation agendas.Publication Natural Disaster Risk Management in the Philippines : Enhancing Poverty Alleviation Through Disaster Reduction(Washington, DC, 2005-10)The Philippines by virtue of its geographic circumstances is highly prone to natural disasters, such as earthquakes, volcanic eruptions, tropical cyclones and floods, making it one of the most disaster prone countries in the world. This report seeks to document the impacts of natural disasters on the social and economic development of the Philippines; assess the country's current capacity to reduce and manage disaster risk; and identify options for more effective management of that risk. The Philippine institutional arrangements and disaster management systems tend to rely on a response, or reactive approach, in contrast to a more effective proactive approach, in which disasters are avoided, by appropriate land-use planning, construction and other pre-event measures which avoid the creation of disaster-prone conditions. To evolve to a more proactive role, it is important that a national framework for comprehensive disaster risk management be prepared and implemented. The framework should incorporate the essential steps of integrated risk management, which include risk identification, risk reduction, and risk sharing/financing. The study identified some specific areas under these key themes that would need to be addressed to improve the current system, discussed through the study. The study also found that currently, the Government and individual households bear the majority of costs caused by natural disasters. More effective options for financing disaster risk, and relieving the burden of disasters from the public sector should be explored, including the idea of a catastrophe insurance pool, and/or contingent credit facilities. Also found was that, despite the high hazard risk in the Philippines, the insurance coverage for residential dwellings' catastrophes is almost non-existent. It is stipulated the Bank should examine the ongoing portfolio to identify how its projects can support the goal of disaster risk reduction. In addition, the Bank should consider more direct support to the development of an integrated disaster management risk approach, through the provision of technical assistance and lending.Publication The Sendai Report(World Bank, Washington, DC, 2012)This report argues that the practice of disaster risk management (DRM) is a defining characteristic of resilient societies, and should therefore be integrated, or 'mainstreamed', into all aspects of development. The report will inform the Development Committee at the annual meetings 2012, and support discussion at the Sendai dialogue, a special event co-organized by the Government of Japan and the World Bank as part of the Annual Meetings program. This event will engage delegates on the importance of mainstreaming DRM, drawing upon the lessons from the great East Japan earthquake and tsunami of 2011, and other disasters. This paper includes the following headings: disasters and development: an alarming trend; disaster risk management in action; national policies and planning; International Development Cooperation; disaster risk management at the World Bank; the way forward: priorities and opportunities; and glossary and references.Publication A Workbook on Planning for Urban Resilience in the Face of Disasters : Adapting Experiences from Vietnam’s Cities to Other Cities(World Bank, 2012-01-26)This workbook is intended to help policy makers in developing countries plan for a safer future in urban areas in the face of natural disasters and the consequences of climate change. It is based on the experiences of three cities in Vietnam, Can Tho, Dong Hoi, and Hanoi, that worked with international and local experts under World Bank supervision to develop local resilience action plans (LRAPs) in 2009-10. An LRAP is a detailed planning document that reflects local concerns and priorities based on the experiences of the past and projections for the future. It is not a wish list of projects that may never be completed because they are too costly or lack political support. Rather, it should be a realistic document that describes and establishes priorities for specific steps that can be undertaken in the near term to adapt to both climate related and other hazards. Regardless of their size, location, political orientation, or technical capacity, other cities can learn from the experiences of these pilot cities to develop their own LRAPs. The purpose of this workbook is to adapt the initial experiences of Can Tho, Dong Hoi, and Hanoi to benefit the national government and other communities in Vietnam and beyond. Indeed, the process described in this workbook was later adopted in the cities of Iloilo, the Philippines; Ningbo, China; and Yogyakarta, Indonesia, and the concluding chapter of this workbook draws on some of the lessons learned in these cities. However, the workbook, while generalizable to other contexts, largely reflects the Vietnamese experience.Publication Building Resilience : Integrating Climate and Disaster Risk into Development(Washington, DC, 2013-11)This report presents the World Bank Group's experience in climate and disaster resilient development and contends that it is essential to eliminate extreme poverty and achieve shared prosperity by 2030. The report argues for closer collaboration between the climate resilience and disaster risk management communities through the incorporation of climate and disaster resilience into broader development processes. Selected case studies are used to illustrate promising approaches, lessons learned, and remaining challenges all in contribution to the loss and damage discussions under the United Nations Framework Convention on Climate Change (UNFCCC). The introduction provides an overview of the UNFCCC and also introduces key concepts and definitions relevant to climate and disaster resilient development. Section two describes the impacts of globally increasing weather-related disasters in recent decades. Section three summarizes how the World Bank Group's goals to end extreme poverty and boost shared prosperity are expected to be affected by rising disaster losses in a changing climate. Section four discusses the issue of attribution in weather-related disasters, and the additional start-up costs involved in climate and disaster resilient development. Section five builds upon the processes and instruments developed by the climate resilience and the disaster risk management communities of practice to provide some early lessons learned in this increasingly merging field. Section six highlights case studies and emerging good practices in climate and disaster resilient development. Section seven concludes the report, summarizing key lessons learned and identifying potential gaps and avenues for future work.

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 Transformation through Tourism : Harnessing Tourism as a Development Tool for Improved Livelihoods(Taylor and Francis, 2011-09-20)Is tourism a viable development tool? While the number of tourist arrivals at developed and developing countries grows, the question continues to arise as to the true propoor impact of tourism. The purpose of this note is to highlight some examples of the World Bank’s recent work in tourism and explore possible approaches for the future.Publication Strategic Communication for Development Projects : A Toolkit for Task Team Leaders(World Bank, Washington, DC, 2003)Efforts to promote general awareness of public health issues - the traditional goal of information, education, and communication (IEC) programs have built a good foundation for population, health, and nutrition (PHN) activities. So communication programs must be designed to support behavior change in key constituencies delivering the message not just to potential clients, but to health providers as well. This document accompanies a toolkit designed to help Bank task managers plan and supervise the implementation of communication activities in PHN projects. It reviews the basic principles of communication for behavior change, presenting a step-by-stop guide to planning and implementing communication activities and linking those steps to the Bank's project cycle. The toolkit contains a set of practical modules, including: communication research approaches for bank projects; a guide to communication indicators; sample term of reference for Bank and Borrower consultants; guide questions for assessing organizational capacity; sample budget and implementation plan; and case studies of best practice in behavior change communication.Publication Coping and Resilience during the Food, Fuel, and Financial Crises(Taylor and Francis, 2012-12-20)This article aggregates qualitative field research from sites in 17 developing countries to describe crisis impacts and analyse how people coped with the food, fuel, and financial crises during 2008–2011. The research uncovered significant hardships behind the apparent resilience, with widespread reports of food insecurity, debt, asset loss, stress, and worsening crime and community cohesion. There were important gender and age differences in the distribution of impacts and coping responses, with women often acting as shock absorbers. The more common sources of assistance were family, friends, community-based and religious organisations with formal social protection and finance less important. The traditional informal safety nets of the poor became depleted as the crisis deepened, pointing to the need for better formal systems for coping with future shocks.Publication Leading with Ideas : Skills for Growth and Equity in Thailand(World Bank, 2012-01-01)In Thailand, enhancing workforce skills and promoting innovation is part of the country's strategy to facilitate the transformation toward a more knowledge-intensive and creative economy generating good jobs. This report provides valuable insight for Thailand to develop the skills necessary to boost ideas-led growth and equity. The report draws on findings from employer surveys, analyses Thailand's skills development performance from the lifecycle perspective, and outlines possible strategies to meet the emerging challenges in matching labor force skills with Thailand's development objectives. In particular, the report highlights possible approaches for consideration while implementing the skills agenda outlined in the eleventh national economic and social development plan. This report will contribute to a constructive discussion and informed decisions that will help the equitable and sustained growth of Thailand's economy.
