Abstract
Microfinance has been heralded as an effective way to address imperfections in credit markets. But from a theoretical perspective, the success of microfinance contracts has puzzling elements. In particular, the group-based mechanisms often employed are vulnerable to free-riding and collusion, although they can also reduce moral hazard and improve selection. The authors created an experimental economics laboratory in a large urban market in Lima, Peru and over seven months conducted 11 different games that allow them to unpack microfinance mechanisms in a systematic way. They find that risk-taking broadly conforms to predicted patterns, but that behavior is safer than optimal. The results help to explain why pioneering microfinance institutions have been moving away from group-based contracts.

    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.

    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.

    The Evolution of Local Participatory Democracy in Nepal
    (Washington, DC: World Bank, 2025-11-05) Bhusal, Thaneshwar; Breen, Michael G; Rao, Vijayendra
    Nepal is, according to its constitution, among the world’s most decentralized countries, with a long and complex tradition of local-level public participation. This paper traces the evolution of Nepal’s modern participatory institutions, examining the extent to which they are “induced” by external interventions versus being “organically” rooted in indigenous practices. The paper identifies three broad phases: an initial focus on participation in project implementation; a subsequent phase that expanded citizen engagement; and a third phase of citizen empowerment, culminating in the 2015 federal constitution, which granted unprecedented local autonomy. The analysis yields five key findings. First, over the past 50 years, successive reforms have progressively expanded opportunities for citizens to influence local decision-making. Second, these reforms have integrated traditional participatory mechanisms into formal institutions of local government. Third, although central-level initiatives exist, most participatory platforms continue to operate at the local level. Fourth, the federal constitution has created a new landscape of local democracy, embedding autonomy and accountability. Fifth, although they are still valued in many ethnic and territorial communities, traditional participatory practices are gradually disappearing. The paper concludes by offering policy recommendations to help donor agencies and governments strengthen Nepal’s democratic trajectory. It argues that effective interventions should build on Nepal’s deep participatory traditions while recognizing the constitutional reality of far-reaching local autonomy.

    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.

    Closing the Gender Gap in Entrepreneurship: Overcoming Challenges in Law and Practice for Female Entrepreneurs
    (Washington, DC: World Bank, 2026-01-07) Behr, Daniela M.; Xi, Yue
    Despite significant strides toward gender equality, women around the world continue to encounter systemic obstacles that hinder their entrepreneurial success. This paper systematically reviews the literature on the barriers female entrepreneurs face and the solutions proposed to overcome these challenges. It discusses institutional factors, financial factors, human capital factors, and social and cultural factors. The literature overview is complemented by a series of stylized facts that illustrate how overcoming some of these existing barriers is correlated with improved women’s entrepreneurship and female labor force participation, drawing on the World Bank’s Women, Business and the Law database as well as the World Bank’s Enterprise Surveys. The findings underscore the need for creating an enabling environment where women can thrive as entrepreneurs.

    Microfinance Games
    (2010) Jakiela, Pamela; Gine, Xavier; Karlan, Dean; Morduch, Jonathan
    Microfinance banks use group-based lending contracts to strengthen borrowers' incentives for diligence, but the contracts are vulnerable to free-riding and collusion. We systematically unpack microfinance mechanisms through ten experimental games played in an experimental economics laboratory in urban Peru. Risk-taking broadly conforms to theoretical predictions, with dynamic incentives strongly reducing risk-taking even without group-based mechanisms. Group lending increases risk-taking, especially for risk-averse borrowers, but this is moderated when borrowers form their own groups. Group contracts benefit borrowers by creating implicit insurance against investment losses, but the costs are borne by other borrowers, especially the most risk averse.

    Finding Missing Markets (and a Disturbing Epilogue) : Evidence from an Export Crop Adoption and Marketing Intervention in Kenya
    (World Bank, Washington, DC, 2008-01) Ashraf, Nava; Giné, Xavier; Karlan, Dean
    In much of the developing world, many farmers grow crops for local or personal consumption despite export options that appear to be more profitable. Thus many conjecture that one or several markets are missing. This paper reports on a randomized controlled trial conducted by DrumNet in Kenya that attempts to help farmers adopt and market export crops. DrumNet provides smallholder farmers with information about how to switch to export crops, makes in-kind loans for the purchase of the agricultural inputs, and provides marketing services by facilitating the transaction with exporters. The experimental evaluation design randomly assigns pre-existing farmer self-help groups to one of three groups: (1) a treatment group that receives all DrumNet services, (2) a treatment group that receives all DrumNet services except credit, or (3) a control group. After one year, DrumNet services led to an increase in production of export oriented crops and lower marketing costs; this translated into household income gains for new adopters. However, one year after the study ended, the exporter refused to continue buying the cash crops from the farmers because the conditions of the farms did not satisfy European export requirements. DrumNet collapsed in this region as farmers were forced to sell to middlemen and defaulted on their loans. The risk of such events may explain, at least partly, why many seemingly more profitable export crops are not adopted.

    Insurance, Credit, and Technology Adoption : Field Experimental Evidence from Malawi
    (World Bank, Washington, DC, 2007-12) Yang, Dean; Giné, Xavier
    The adoption of new agricultural technologies may be discouraged because of their inherent riskiness. This study implemented a randomized field experiment to ask whether the provision of insurance against a major source of production risk induces farmers to take out loans to invest in a new crop variety. The study sample was composed of roughly 800 maize and groundnut farmers in Malawi, where by far the dominant source of production risk is the level of rainfall. We randomly selected half of the farmers to be offered credit to purchase high-yielding hybrid maize and improved groundnut seeds for planting in the November 2006 crop season. The other half of the farmers were offered a similar credit package but were also required to purchase (at actuarially fair rates) a weather insurance policy that partially or fully forgave the loan in the event of poor rainfall. Surprisingly, take up was lower by 13 percentage points among farmers offered insurance with the loan. Take-up was 33.0 percent for farmers who were offered the uninsured loan. There is suggestive evidence that the reduced take-up of the insured loan was due to the high cognitive cost of evaluating the insurance: insured loan take-up was positively correlated with farmer education levels. By contrast, the take-up of the uninsured loan was uncorrelated with farmer education.

    Microinsurance : A Case Study of the Indian Rainfall Index Insurance Market
    (2010-10-01) Menand, Lev; Giné, Xavier; Townsend, Robert; Vickery, James
    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.

    Latest Findings from Randomized Evaluations of Microfinance
    (World Bank, Washington, DC, 2011-12) Bauchet, Jonathan; Marshall, Cristobal; Starita, Laura; Thomas, Jeanette; Yalouris, Anna
    This paper summarizes the latest research findings from a new body of empirical evidence that uses randomized evaluations, similar to those used in medical trials, to compare how one group responds to access to specific new financial services against how a comparable group fares without those services. This paper goes back a couple of years to the first studies that used this approach, and summarizes a series of research studies presented at the October 2010 microfinance impact and innovation conference in New York. These studies evaluated product design for a range of financial services, including credit, savings, and insurance. The studies discussed here were undertaken by research affiliates of Innovations for Poverty Action (IPA), the Financial Access Initiative (FAI), and the Abdul Latif Jameel Poverty Action Lab (J-PAL) at the Massachusetts Institute of Technology; they are all randomized evaluations unless otherwise specified. Part one of this paper reviews the main results from randomized evaluations that measure the impact of microcredit and micro savings on business investment and creation, consumption, and household well-being. Part two presents evidence from evaluations of products and delivery design. Part three discusses the evidence on micro insurance products.

    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.

    Financing Business Innovation
    (World Bank, Washington, DC, 2012) World Bank Group
    Innovation is the main driver of long-term economic growth. The accumulation of capital, whether in the form of physical assets such as plants and equipment, or through better human capital, cannot indefinitely sustain growth unless new products, services, processes, and/or business models are developed and implemented. This paper describes the actors involved and the types of funding available at different stages of the innovation process, the rationales for public intervention, and the advantages and disadvantages of some of the most commonly used policy instruments. Innovation activities are more difficult to finance than other types of investment for several reasons. Innovation produces an intangible asset that does not typically constitute accepted collateral to obtain external funding. Also, the technological and market uncertainty of innovation activities makes the returns to investment highly uncertain, creating significant problems for the standard risk adjustment methods used by providers of funds. This paper uses a streamlined version of an innovation process with three stages to categorize the different sources of finance available; in reality, considerable crossover takes places among instruments because innovation processes are not discrete.

    Ending Poverty in South Asia : Ideas That Work
    (Washington, DC: World Bank, 2007) Glinskaya, Elena; Narayan, Deepa
    The case studies in this book were developed as part of a year-long learning process initiated by the World Bank in 2003-4 to examine large scale poverty reduction programs in a wide range of developing countries around the world. This volume presents 12 of the case studies from South Asia. . The last two decades saw substantial change in the countries of South Asia. All countries of the subcontinent experienced more rapid growth than in the earlier decades and also saw a definite reduction in the incidence of poverty, resulting in the improvement of the lives of hundreds of millions of poor people. One common element was the adoption of broad based economic reforms involving rethinking of earlier approaches to development. The reforms in South Asia were notable in that they were homegrown, gradual, and accompanied by continual redesign and fine tuning. Individuals can make a difference in fighting poverty when ways are found to institutionalize creative ideas and apply them on a scale extending beyond pilot projects. This book recounts 12 such cases from a range of countries and sectors in the South Asia region, with a focus on how these programmes scaled up and on the potential for applying lessons in other settings. These case studies do not offer a blueprint or model for poverty reduction; there is no single model. Nor do they cover every issue that is important. But they suggest the range of ideas that can be successful and the underlying principles that cut across these diverse initiatives. All the programmes tap the imagination and ingenuity of the South Asian people- in government offices, in civil society organizations, in the private sector, and in the villages and urban neighborhoods. All seek to empower poor people to access the economic opportunities and basic services so necessary to human dignity. The lessons are complex, and applying them will undoubtedly require redesign and fine-tuning to fit the initiatives to the local context. What is important, however, is that the experience of the last two decades has shown that reforms and scaling-up innovations can work in South Asia-and if these examples can be strengthened and expanded in the coming decades, the dreams of a subcontinent free of poverty may be realized.

    Leveraging Institutional Platforms to Promote Convergence
    (World Bank, Washington, DC, 2020-03) Kumar, Shantanu; Pinto, Alreena Renita; Gupta, Arshia
    The launch of NRLM to address rural poverty marks a paradigm shift in poverty alleviation because unlike other programs that preceded it, the NRLM focuses on training and capacity building, and enabling women to prepare and implement their livelihoods plans through own institutions and from banks. The importance of promoting convergence with other rural development programs, as well other ministries, is enshrined in the framework of NRLM.
