Abstract
This paper studies the role of morality in the decision to repay debts. Using a field experiment with a large Islamic bank in Indonesia, the paper finds that moral appeals strongly increase credit card repayments. In this setting, all of the banks late-paying credit card customers receive a basic reminder to repay their debt one day after they miss the payment due date. In addition, two days before the end of a ten-day grace period, clients in a treatment group also receive a text message that cites an Islamic religious text and states that “non-repayment of debts by someone who is able to repay is an injustice.” This message increases the share of customers meeting their minimum payments by nearly 20 percent. By contrast, sending either a simple reminder or an Islamic quote that is unrelated to debt repayment has no effect on the share of customers making the minimum payment. Clients also respond more strongly to this moral appeal than to substantial financial incentives: receiving the religious message increases repayments by more than offering a cash rebate equivalent to 50 percent of the minimum repayment. Finally, the paper finds that removing religious aspects from the quote does not change its effectiveness, suggesting that the moral appeal of the message does not necessarily rely on its religious connotation.

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 Debt Overhang in Emerging Europe?(2011-08-01)This paper assesses the extent to which debt overhang poses a constraint to economic activity in Emerging Europe, as the region emerges from the recent financial and economic crisis. At the macroeconomic level, it finds that the external imbalance problem for Emerging Europe has been in most cases more one of flows (high current account deficits in the pre-crisis years) rather than large stocks of external debt. A high reliance on equity funding means that net external debt is far lower than net external liabilities. Domestic balance sheets have expanded quite rapidly but sector liabilities remain relatively low compared with advanced economies. With the important exception of Hungary, public debt levels also remain relatively low in Emerging Europe. At the microeconomic level, the potential for debt overhang in the corporate sector is limited to a few countries: Latvia, Lithuania, Estonia, and Slovenia. Due to the low incidence of household debt, hardly any country, except Estonia, seems to face a threat of debt overhang in the household sector. The strong increase in non-performing loans compared with pre-crisis bank profitability suggests that debt overhang in the banking sector is a threat in Ukraine, Latvia, Lithuania, Hungary, Georgia, and Albania. Financial integration of Emerging Europe seems to have contributed to the transmission of the crisis to the region. At the same time, this integration is helping the region in managing the crisis by concerted actions of the major players.Publication What Does Debt Relief Do for Development? Evidence from India’s Bailout Program for Highly-Indebted Rural Households(2012-11)This paper studies the impact of a large debt relief program, intended to attenuate investment constraints among highly-indebted households in rural India. It isolates the causal effect of bankruptcy-like debt relief settlements using a natural experiment arising from India's Debt Relief Program for Small and Marginal Farmers -- one of the largest debt relief initiatives in history. The analysis shows that debt relief has a persistent effect on the level of household debt, but does not increase investment and productivity as predicted by theories of debt overhang. Instead, the anticipation of future credit constraints leads to a greater reliance on informal financing, lower investment and a decline in productivity among bailout recipients. The results suggest that one-time settlements may be insufficient to incentivize new investment, but can have significant real effects through their impact on borrower expectations.Publication Responsible Lending : Overview of Regulatory Tools(World Bank, Washington, DC, 2013-10)This paper provides an overview of key regulatory actions a government may implement to support responsible lending. It covers a range of possible interventions, including the provision of information, developing consumers' ability to use that information, formal requirements for responsible behavior of the lenders, and regulatory limits for loans. Because the research on the effectiveness of the responsible lending policies is limited, the paper focuses on literature overview and empirical evidence when available and uses case studies to describe key policies. A regulator seeking to develop a responsible lending framework must cover all areas of the responsible lending regulatory and educational mix. No single solution may be applied universally. The regulators must ensure they understand the retail credit markets. The paper identifies main policy options and areas for further research. Better data on lending markets before and after the rules are introduced and more detailed understanding of consumer behavior helps in identifying effective regulatory rules and supervisory actions that help ensure more responsible lending while not limiting financial inclusion and the growth of the credit market. Access to credit is sometimes considered by national authorities a crucial measure of financial inclusion. Low-income countries where microfinance is a key contributor financial inclusion may use similar measures.Publication The Economic Effects of a Borrower Bailout : Evidence from an Emerging Market(World Bank Group, Washington, DC, 2014-11)This paper studies the credit market implications and real effects of one the largest borrower bailout programs in history, enacted by the government of India against the backdrop of the 2008-2009 financial crisis. The study finds that the stimulus program had no effect on productivity, wages, or consumption, but led to significant changes in credit allocation and an increase in defaults. Post-program loan performance declines faster in districts with greater exposure to the program, an effect that is not driven by greater risk-taking of banks. Loan defaults become significantly more sensitive to the electoral cycle after the program, suggesting the anticipation of future credit market interventions as an important channel through which moral hazard in loan repayment is intensified.Publication Emergency Hand Loan(Washington, DC, 2015-03)The poor and other underserved populations in developing countries have unique financial service s needs. However, there is often a mismatch between what financial institutions offer and what underserved populations need or want. This product gap may reflect a lack of interest by financial institutions in designing more target products, or a lack of willingness or capacity on the part of financial institutions to design, market and implement tailor-made financial products. The objectives of the Product Design Case Studies are to 1) develop expertise related to product design and innovation processes through a better understanding of best practices in the field, in depth research and application of behavioral economics concepts; 2) increase awareness of product design/innovation and the links between product development and financial inclusion; and 3) generate publicity and knowledge sharing around product design and innovation. While the hand loan product was broadly successful in achieving its original intent, the pilot encountered considerable institutional and execution challenges that are instructive for future product innovation efforts. The first two sections describe the problem and the innovative product designed to address it. The next section describes the final design and implementation of the product in detail. The fourth section covers post-pilot data collection and results. The final sections discuss lessons learned and planned future enhancements.

Publication Direct and Indirect Impacts of Transport Mobility on Access to Jobs: Evidence from South Africa(Washington, DC: World Bank, 2025-11-12)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.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 Preventing, Detecting, and Deterring Fraud in Social Health Insurance Programs(World Bank, Washington, DC, 2018-11)This paper draws lessons from anti-fraud experiences in social health insurance programs of six selected countries across the income spectrum: Indonesia, the Philippines, Republic of Korea, Croatia, Turkey, and the United States. A standardized questionnaire was used to collect information on how the programs prevent, detect, and deter fraud. The questionnaire was supplemented by a literature review and conversations with key informants. The analysis summarizes similarities and differences in the legal framework, institutional mechanisms, and capacity to manage fraud. Across all countries, the primary responsibility for managing fraud lies with the public entity that administers the program. In terms of capacity, all program-administering agencies have dedicated anti-fraud units and staff. In addition, all countries have specific anti-fraud policies and guidelines that address fraud and have a clear operational and legal definition of fraud. In terms of preventing fraud, the use of pre-authorization screening for high-end procedures is common. For detecting fraud, most countries use anti-fraud ‘hotlines’ and encourage other forms of reporting of suspected fraudulent behavior; the use of ‘red flags’-triggers that identify suspicious claims based on deviations from norms, is also common. The level of sophistication in using data analytics to detect potential fraud, however, varies across countries. Social health insurance programs in higher-income countries are more likely to use advanced statistical and data-mining techniques compared to those in lower-income countries. All programs across all countries undertake post-reimbursement medical claims and beneficiary audits. In terms of deterring fraud, sanctions often include the use of financial penalties, cancellation of contracts, and criminal prosecutions; however, in most countries, public providers are not penalized and prosecuted to the same degree as private providers.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 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.
