Abstract
In order to understand the impact of facilitating access to savings accounts and to examine the importance of these barriers for formal savings, author designed a field experiment among smallholder cash crop farmers in Malawi. In partnership with a local microfinance institution, author randomized offers of account-opening and deposit assistance for formal savings accounts. In order to test the importance of individual self-control problems or pressure to share resources with others in the social network, treated farmers were randomly assigned to one of two types of savings interventions. The first group was offered an 'ordinary' bank account with standard features. The second group was offered the ordinary account as well as a 'commitment' savings account.

Publication Commitments to Save : A Field Experiment in Rural Malawi(2011-08-01)This paper reports the results of a field experiment that randomly assigned smallholder cash crop farmers formal savings accounts. In collaboration with a microfinance institution in Malawi, the authors tested two primary treatments, offering either: 1) "ordinary" accounts, or 2) both ordinary and "commitment" accounts. Commitment accounts allowed customers to restrict access to their own funds until a future date of their choosing. A control group was not offered any account but was tracked alongside the treatment groups. Only the commitment treatment had statistically significant effects on subsequent outcomes. The effects were positive and large on deposits and withdrawals immediately prior to the next planting season, agricultural input use in that planting, crop sales from the subsequent harvest, and household expenditures in the period after harvest. Across the set of key outcomes, the commitment savings treatment had larger effects than the ordinary savings treatment. Additional evidence suggests that the positive impacts of commitment derive from keeping funds from being shared with one's social network.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 Insurance, Credit, and Technology Adoption : Field Experimental Evidence from Malawi(World Bank, Washington, DC, 2007-12)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.Publication Identification Strategy : A Field Experiment on Dynamic Incentives in Rural Credit Markets(2010-10-01)How do borrowers respond to improvements in a lender's ability to punish defaulters? This paper reports the results of a randomized field experiment in rural Malawi that examines the impact of fingerprinting borrowers in a context where a unique identification system is absent. Fingerprinting allows the lender to more effectively use dynamic repayment incentives: withholding future loans from past defaulters while rewarding good borrowers with better loan terms. Consistent with a simple model of borrower heterogeneity and information asymmetries, fingerprinting led to substantially higher repayment rates for borrowers with the highest ex ante default risk, but had no effect for the rest of the borrowers. The change in repayment rates is driven by reductions in adverse selection (smaller loan sizes) and lower moral hazard (for example, less diversion of loan-financed fertilizer from its intended use on the cash crop).Publication Commitment Savings Accounts in Malawi(Washington, DC, 2015-03)Malawi s economy is heavily dependent on agriculture, especially tobacco, which comprises a majority of the country s exports. Tobacco farmers have one harvest a year, and while their income stream occurs over several months it must last them for the entire year, making it difficult to smooth consumption throughout the year. The objective of this case study is to present the design and implementation of a commitment savings product for groups of tobacco farmers in Malawi. The product was successful in encouraging savings, increasing input purchases and yields for the next year s harvest, and increasing consumption after the harvest. The following sections describe the lack of formal savings options for rural farmers, the behavioral concept behind commitment savings accounts, the product designed to address these problems and subsequent changes to the original design, results of a field experiment evaluating the product, and lessons learned for other commitment savings products.

Publication World Development Report 2023: Migrants, Refugees, and Societies(Washington, DC : World Bank, 2023-04-25)Migration is a development challenge. About 184 million people—2.3 percent of the world’s population—live outside of their country of nationality. Almost half of them are in low- and middle-income countries. But what lies ahead? As the world struggles to cope with global economic imbalances, diverging demographic trends, and climate change, migration will become a necessity in the decades to come for countries at all levels of income. If managed well, migration can be a force for prosperity and can help achieve the United Nations’ Sustainable Development Goals. World Development Report 2023 proposes an innovative approach to maximize the development impacts of cross-border movements on both destination and origin countries and on migrants and refugees themselves. The framework it offers, drawn from labor economics and international law, rests on a “Match and Motive Matrix” that focuses on two factors: how closely migrants’ skills and attributes match the needs of destination countries and what motives underlie their movements. This approach enables policy makers to distinguish between different types of movements and to design migration policies for each. International cooperation will be critical to the effective management of migration.Publication Europe and Central Asia Economic Update, Fall 2024: Better Education for Stronger Growth(Washington, DC: World Bank, 2024-10-17)Economic growth in Europe and Central Asia (ECA) is likely to moderate from 3.5 percent in 2023 to 3.3 percent this year. This is significantly weaker than the 4.1 percent average growth in 2000-19. Growth this year is driven by expansionary fiscal policies and strong private consumption. External demand is less favorable because of weak economic expansion in major trading partners, like the European Union. Growth is likely to slow further in 2025, mostly because of the easing of expansion in the Russian Federation and Turkiye. This Europe and Central Asia Economic Update calls for a major overhaul of education systems across the region, particularly higher education, to unleash the talent needed to reinvigorate growth and boost convergence with high-income countries. Universities in the region suffer from poor management, outdated curricula, and inadequate funding and infrastructure. A mismatch between graduates' skills and the skills employers are seeking leads to wasted potential and contributes to the region's brain drain. Reversing the decline in the quality of education will require prioritizing improvements in teacher training, updated curricula, and investment in educational infrastructure. In higher education, reforms are needed to consolidate university systems, integrate them with research centers, and provide reskilling opportunities for adult workers.Publication World Development Report 2024(Washington, DC: World Bank, 2024-08-01)Middle-income countries are in a race against time. Many of them have done well since the 1990s to escape low-income levels and eradicate extreme poverty, leading to the perception that the last three decades have been great for development. But the ambition of the more than 100 economies with incomes per capita between US$1,100 and US$14,000 is to reach high-income status within the next generation. When assessed against this goal, their record is discouraging. Since the 1970s, income per capita in the median middle-income country has stagnated at less than a tenth of the US level. With aging populations, growing protectionism, and escalating pressures to speed up the energy transition, today’s middle-income economies face ever more daunting odds. To become advanced economies despite the growing headwinds, they will have to make miracles. Drawing on the development experience and advances in economic analysis since the 1950s, World Development Report 2024 identifies pathways for developing economies to avoid the “middle-income trap.” It points to the need for not one but two transitions for those at the middle-income level: the first from investment to infusion and the second from infusion to innovation. Governments in lower-middle-income countries must drop the habit of repeating the same investment-driven strategies and work instead to infuse modern technologies and successful business processes from around the world into their economies. This requires reshaping large swaths of those economies into globally competitive suppliers of goods and services. Upper-middle-income countries that have mastered infusion can accelerate the shift to innovation—not just borrowing ideas from the global frontiers of technology but also beginning to push the frontiers outward. This requires restructuring enterprise, work, and energy use once again, with an even greater emphasis on economic freedom, social mobility, and political contestability. Neither transition is automatic. The handful of economies that made speedy transitions from middle- to high-income status have encouraged enterprise by disciplining powerful incumbents, developed talent by rewarding merit, and capitalized on crises to alter policies and institutions that no longer suit the purposes they were once designed to serve. Today’s middle-income countries will have to do the same.Publication Services Unbound(Washington, DC: World Bank, 2024-12-09)Services are a new force for innovation, trade, and growth in East Asia and Pacific. The dramatic diffusion of digital technologies and partial policy reforms in services--from finance, communication, and transport to retail, health, and education--is transforming these economies. The result is higher productivity and changing jobs in the services sector, as well as in the manufacturing sectors that use these services. A region that has thrived through openness to trade and investment in manufacturing still maintains innovation-inhibiting barriers to entry and competition in key services sectors. 'Services Unbound: Digital Technologies and Policy Reform in East Asia and Pacific' makes the case for deeper domestic reforms and greater international cooperation to unleash a virtuous cycle of increased economic opportunity and enhanced human capacity that would power development in the region.Publication Unlocking the Power of Healthy Longevity(Washington, DC: World Bank, 2024-09-12)Noncommunicable diseases (NCDs) are among the major health and development challenges of our time. Every year, about 41 million people die due to NCDs. This makes up about 74 percent of all deaths globally, the majority of which are in low- and middle-income countries (LMICs). Countless more people live with NCDs every day. Yet, NCDs are largely treatable and preventable. The risk of developing NCDs and deaths from them can both be lowered with appropriate attention to prevention and treatment. However, weak health systems and limited access to affordable care and information, especially in LMICs, contribute to lapses in seeking and receiving appropriate and timely care. This compendium is a compilation of 18 chapters, each exploring a different but related topic in the nexus of NCDs, human capital, and productivity. It is based on a series of analytical work taken up by the World Bank to support the Healthy Longevity Initiative (HLI) - a collaborative effort between the World Bank, the University of Toronto, and key academic and development partners including the Harvard University and the University of Washington. The HLI presents one of a growing set of efforts to increase the urgency of policy response to NCDs across the world.
