Abstract
Accurate measurement of stock levels, turnover, and profitability in microenterprises in developing countries is difficult because the majority of these firms do not keep detailed records. This paper tests the use of radio frequency identification tags as a means of objectively measuring stock levels and stock flow in small retail firms in Sri Lanka. In principle, the tags offer the potential to track stock movements accurately. The paper compares the stock counts obtained from RFID reads to physical stock counts and to survey responses. There are three main findings. First, current RFID-technology is more difficult to use, and more time-consuming to employ, than had been envisaged. Second, the technology works reasonably well for paper products, but very poorly for most products sold by microenterprises: on average only about one-quarter of the products tagged could be read and there was considerable day-to-day variation in read-efficiency. Third, a comparison of survey responses and physical stock-takes shows much higher accuracy for survey measures. As a result, the study concludes that this technology is currently unsuitable for improving stock measurement in microenterprises, except perhaps for a few products.

Publication Intergenerational Income Mobility around the World(Washington, DC: World Bank, 2025-07-09)This paper introduces a new global database with estimates of intergenerational income mobility for 87 countries, covering 84 percent of the world’s population. This marks a notable expansion of the cross-country evidence base on income mobility, particularly among low- and middle-income countries. The estimates indicate that the negative association between income mobility and inequality (known as the Great Gatsby Curve) continues to hold across this wider range of countries. The database also reveals a positive association between income mobility and national income per capita, suggesting that countries achieve higher levels of intergenerational mobility as they grow richer.Publication The Future of Poverty(Washington, DC: World Bank, 2025-07-15)Climate change is increasingly acknowledged as a critical issue with far-reaching socioeconomic implications that extend well beyond environmental concerns. Among the most pressing challenges is its impact on global poverty. This paper projects the potential impacts of unmitigated climate change on global poverty rates between 2023 and 2050. Building on a study that provided a detailed analysis of how temperature changes affect economic productivity, this paper integrates those findings with binned data from 217 countries, sourced from the World Bank’s Poverty and Inequality Platform. By simulating poverty rates and the number of poor under two climate change scenarios, the paper uncovers some alarming trends. One of the primary findings is that the number of people living in extreme poverty worldwide could be nearly doubled due to climate change. In all scenarios, Sub-Saharan Africa is projected to bear the brunt, contributing the largest number of poor people, with estimates ranging between 40.5 million and 73.5 million by 2050. Another significant finding is the disproportionate impact of inequality on poverty. Even small increases in inequality can lead to substantial rises in poverty levels. For instance, if every country’s Gini coefficient increases by just 1 percent between 2022 and 2050, an additional 8.8 million people could be pushed below the international poverty line by 2050. In a more extreme scenario, where every country’s Gini coefficient increases by 10 percent between 2022 and 2050, the number of people falling into poverty could rise by an additional 148.8 million relative to the baseline scenario. These findings underscore the urgent need for comprehensive climate policies that not only mitigate environmental impacts but also address socioeconomic vulnerabilities.Publication Engineering Ukraine’s Wirtschaftswunder(Washington, DC: World Bank, 2025-07-29)As Ukraine emerges from the devastation of war, it faces a historic opportunity to engineer its own Wirtschaftswunder—a productivity-driven economic transformation akin to post-war West Germany. While investment-led growth may offer quick wins, it is efficiency, innovation, and institutional reform that will determine Ukraine’s long-term economic trajectory. Drawing on rich micro-level firm data spanning 25 years, this paper uncovers deep structural distortions that have suppressed creative destruction and productivity in Ukraine. It finds that business dynamism is on the decline, alongside rising market concentration among incumbent businesses, including low productivity state owned enterprises. To inform priorities for reviving business dynamism, this study develops a model of creative destruction drawing on Acemoglu et al. (2018) and Akcigit et al. (2021). The quantitative assessment highlights that policies that discipline entrenched incumbents are the bedrock for reviving business dynamism and engineer Ukraine’s Wirtschaftswunder. Policies targeting specific types of firms have limited efficacy when incumbents run wild.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 Disentangling the Key Economic Channels through Which Infrastructure Affects Jobs(Washington, DC: World Bank, 2025-04-03)This paper takes stock of the literature on infrastructure and jobs published since the early 2000s, using a conceptual framework to identify the key channels through which different types of infrastructure impact jobs. Where relevant, it highlights the different approaches and findings in the cases of energy, digital, and transport infrastructure. Overall, the literature review provides strong evidence of infrastructure’s positive impact on employment, particularly for women. In the case of electricity, this impact arises from freeing time that would otherwise be spent on household tasks. Similarly, digital infrastructure, particularly mobile phone coverage, has demonstrated positive labor market effects, often driven by private sector investments rather than large public expenditures, which are typically required for other large-scale infrastructure projects. The evidence on structural transformation is also positive, with some notable exceptions, such as studies that find no significant impact on structural transformation in rural India in the cases of electricity and roads. Even with better market connections, remote areas may continue to lack economic opportunities, due to the absence of agglomeration economies and complementary inputs such as human capital. Accordingly, reducing transport costs alone may not be sufficient to drive economic transformation in rural areas. The spatial dimension of transformation is particularly relevant for transport, both internationally—by enhancing trade integration—and within countries, where economic development tends to drive firms and jobs toward urban centers, benefitting from economies scale and network effects. Turning to organizational transformation, evidence on skill bias in developing countries is more mixed than in developed countries and may vary considerably by context. Further research, especially on the possible reasons explaining the differences between developed and developing economies, is needed.

Publication ICTs for Agriculture in Africa(World Bank, Washington, DC, 2014-01)The strategic application of information and communications technology (ICT) to the agricultural industry, the largest economic sector in most African countries, offers the best opportunity for economic growth and poverty alleviation on the continent. Food security is paramount for the survival of individuals, families, and ultimately nations, yet Africa's agriculture sector has been in decline over the past 40 years. African agriculture is predominantly rain-fed, has low-yielding production, and lacks access to critical information, market facilitation, and financial intermediation services. The role that ICT can play in addressing these challenges is increasing as personal ICT devices such as mobile phones or tablet are becoming more widely available. ICT, when embedded in broader stakeholder systems, can bring economic development and growth as it can help bridge critical knowledge gaps. Mobile technology, on the other hand, is increasingly being adopted as the technology of choice for delivery of ICT services and solutions. The wider adoption of ICT in agriculture is of strategic importance to five main stakeholder groups: businesses; farmers; researchers; government; and citizens. In identifying the ways in which ICT can help agriculture, it is useful to view the farming life cycle as a three-stage process: pre-cultivation; crop cultivation and harvesting; and crop cultivation and harvesting.Publication Supply Chain Security Guide(World Bank, Washington, DC, 2009)A supply chain is a system of resources, organizations, people, technologies, activities and information involved in the act of transporting goods from producer to consumer and user. This (SCS) guide is intended for trade and transport government officials, port authorities and transport, cargo and logistics communities, in particular in developing countries. The purpose of the guide is to make concerned trade and transport-related officials, managers and personnel in developing countries acquainted with, and aware of, the many initiatives mushrooming in the field of supply chain security, what these will mean for their respective organizations, and how to tackle the inlaid challenges. This chapter attempts to clarify the background and current status of the multitude of programs that exist across the world today. This is achieved by, firstly, giving a brief account of the changing security environment (post 9/11) and its resulting implications for SCS programs. This is important as it helps to explain the motivation of the programs which are later expanded upon in more detail within the chapter. Within this section, the motivations for different types of programs, not directly linked to the events of 9/11 but to other reasons, such as combating illegal activities, enhancement of efficiency and standardization are also explained. Secondly, a list of the main programs is present under four main subheadings: compulsory programs, major voluntary programs, regional or national programs, and others. Tables are presented at the end of the section summarizing the main points of each program. Finally, some of the issues surrounding the programs are presented in the concluding section.Publication Using Locational Data from Mobile Phones to Enhance the Science of Delivery(World Bank, Washington, DC, 2014-06)The objective of this report is to examine the potential of locational data for the 'science of delivery' in the field of development. The 'science of delivery' is a term popularized by the World Bank President, Jim Yong Kim, and refers to using evidence-based experimentation to improve development outcomes (Walji, 2013). In this context, locational data is a new tool that is starting to be used in a variety of development fields including health, education, disaster risk management, traffic planning etc. this broad introduction to the topic in chapter one, the next chapter explores the technology behind locational data. Chapter three presents the methodology followed in this research and chapter four, which is the heart of this report, then presents a series of mini case studies of how it is actually being used in a representative sample of different development fields. This is the 'evidence-based experimentation' which can be harnessed to improve the 'science of delivery', and examples of both active and passive collection of locational data are presented. Finally, chapter five examines, in broader terms, the longer term potential of locational data as a development tool, once smartphone ownership becomes more widespread.Publication Global Value Chains in the Electronics Industry : Was the Crisis a Window of Opportunity for Developing Countries?(2010-09-01)This paper presents evidence of the importance of electronics global value chains (GVCs) in the global economy, and discusses the effects of the recent economic crisis on the industry. The analysis focuses on how information is exchanged and introduces the concept of "value chain modularity." The authors identify three key firm level actors -- lead firms, contract manufacturers, and platform leaders -- and discuss their development, or "co-evolution" in the context of global integration. Company, cluster, and country case studies are then presented to illustrate how supplier capabilities in various places have developed in the context of electronics global value chains. The findings identify some of the persistent limits to upgrading experienced by even the most successful firms in the developing world. Four models used by developing country firms to overcome these limitations are presented: (1) global expansion though acquisition of declining brands (emerging multinationals); (2) separation of branded product divisions from contract manufacturing (original design manufacturing (ODM) spinoffs); (3) successful mixing of contract manufacturing and branded products (platform brands) for contractors with customers not in the electronic hardware business; and (4) the founding of factory-less product firms that rely on global value chains for a range of inputs, including production (emerging factory-less start-ups).Publication ICT as an Enabler of Transformation in Ethiopia(World Bank, Washington, DC, 2014-01)Over the last two decades, Ethiopia has achieved remarkable progress toward social and economic indicators. Analytical evidence shows that development projects with a significant information and communication technology (ICT) component have a higher potential to achieve greater outcomes on the ground than the ones not supported by ICT. This is why the Government of Ethiopia sees ICT within the broader context of its socioeconomic development objectives and believes that it should take advantage of today's most innovative and reliable technologies to accelerate the rate of economic growth and alleviate poverty in the country. The Government of Ethiopia has requested the ICT sector unit of the World Bank to prepare a comprehensive report on how ICT can be used to achieve a true transformation of the Ethiopian economy and society. Therefore, this report explores how ICT can be leveraged to foster the development of an ICT-enabled industry and the private sector in general, to enhance public sector performance, to develop the agriculture and health sectors, and finally how all these efforts can lead to the emergence of an open innovation ecosystem. This report takes stock of current and recently-launched ICT initiatives in Ethiopia and develops sector-specific recommendations based on international best practices that help leverage the transformative power of ICT to improve the social and economic well-being of citizens and achieve rapid and sustainable socioeconomic development. The report explores following topics: background in chapter one, presents fostering the development of ICT-enabled industry and the private sector in chapter two. Chapter three deals with enhancing the performance of the public sector. Chapter four is developing the health sector. Chapter five deals with agricultural and rural development. Chapter six helps in creating an open innovation ecosystem; and chapter seven presents recommendations for ICT-enabled transformation in Ethiopia.

Publication World Development Report 2014(Washington, DC, 2013-10-06)The past 25 years have witnessed unprecedented changes around the world—many of them for the better. Across the continents, many countries have embarked on a path of international integration, economic reform, technological modernization, and democratic participation. As a result, economies that had been stagnant for decades are growing, people whose families had suffered deprivation for generations are escaping poverty, and hundreds of millions are enjoying the benefits of improved living standards and scientific and cultural sharing across nations. As the world changes, a host of opportunities arise constantly. With them, however, appear old and new risks, from the possibility of job loss and disease to the potential for social unrest and environmental damage. If ignored, these risks can turn into crises that reverse hard-won gains and endanger the social and economic reforms that produced these gains. The World Development Report 2014 (WDR 2014), Risk and Opportunity: Managing Risk for Development, contends that the solution is not to reject change in order to avoid risk but to prepare for the opportunities and risks that change entails. Managing risks responsibly and effectively has the potential to bring about security and a means of progress for people in developing countries and beyond. Although individuals’ own efforts, initiative, and responsibility are essential for managing risk, their success will be limited without a supportive social environment—especially when risks are large or systemic in nature. The WDR 2014 argues that people can successfully confront risks that are beyond their means by sharing their risk management with others. This can be done through naturally occurring social and economic systems that enable people to overcome the obstacles that individuals and groups face, including lack of resources and information, cognitive and behavioral failures, missing markets and public goods, and social externalities and exclusion. These systems—from the household and the community to the state and the international community—have the potential to support people’s risk management in different yet complementary ways. The Report focuses on some of the most pressing questions policy makers are asking. What role should the state take in helping people manage risks? When should this role consist of direct interventions, and when should it consist of providing an enabling environment? How can governments improve their own risk management, and what happens when they fail or lack capacity, as in many fragile and conflict-affected states? Through what mechanisms can risk management be mainstreamed into the development agenda? And how can collective action failures to manage systemic risks be addressed, especially those with irreversible consequences? The WDR 2014 provides policy makers with insights and recommendations to address these difficult questions. It should serve to guide the dialogue, operations, and contributions from key development actors—from civil society and national governments to the donor community and international development organizations.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 Classroom Assessment to Support Foundational Literacy(Washington, DC: World Bank, 2025-03-21)This document focuses primarily on how classroom assessment activities can measure students’ literacy skills as they progress along a learning trajectory towards reading fluently and with comprehension by the end of primary school grades. The document addresses considerations regarding the design and implementation of early grade reading classroom assessment, provides examples of assessment activities from a variety of countries and contexts, and discusses the importance of incorporating classroom assessment practices into teacher training and professional development opportunities for teachers. The structure of the document is as follows. The first section presents definitions and addresses basic questions on classroom assessment. Section 2 covers the intersection between assessment and early grade reading by discussing how learning assessment can measure early grade reading skills following the reading learning trajectory. Section 3 compares some of the most common early grade literacy assessment tools with respect to the early grade reading skills and developmental phases. Section 4 of the document addresses teacher training considerations in developing, scoring, and using early grade reading assessment. Additional issues in assessing reading skills in the classroom and using assessment results to improve teaching and learning are reviewed in section 5. Throughout the document, country cases are presented to demonstrate how assessment activities can be implemented in the classroom in different contexts.Publication World Development Report 2015(Washington, DC: World Bank, 2015)Every policy relies on explicit or implicit assumptions about how people make choices. Those assumptions typically rest on an idealized model of how people think, rather than an understanding of how everyday thinking actually works. This year’s World Development Report argues that a more realistic account of decision-making and behavior will make development policy more effective. The Report emphasizes what it calls 'the three marks of everyday thinking.' In everyday thinking, people use intuition much more than careful analysis. They employ concepts and tools that prior experience in their cultural world has made familiar. And social emotions and social norms motivate much of what they do. These insights together explain the extraordinary persistence of some social practices, and rapid change in others. They also offer new targets for development policy. A richer understanding of why people save, use preventive health care, work hard, learn, and conserve energy provides a basis for innovative and inexpensive interventions. The insights reveal that poverty not only deprives people of resources but is an environment that shapes decision making, a fact that development projects across the board need to recognize. The insights show that the psychological foundations of decision making emerge at a young age and require social support. The Report applies insights from modern behavioral and social sciences to development policies for addressing poverty, finance, productivity, health, children, and climate change. It demonstrates that new policy ideas based on a richer view of decision-making can yield high economic returns. These new policy targets include: the choice architecture (for example, the default option); the scope for social rewards; frames that influence whether or not a norm is activated; information in the form of rules of thumb; opportunities for experiences that change mental models or social norms. Finally, the Report shows that small changes in context have large effects on behavior. As a result, discovering which interventions are most effective, and with which contexts and populations, inherently requires an experimental approach. Rigor is needed for testing the processes for delivering interventions, not just the products that are delivered.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.
