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 Global Poverty Revisited Using 2021 PPPs and New Data on Consumption(Washington, DC: World Bank, 2025-06-05)Recent improvements in survey methodologies have increased measured consumption in many low- and lower-middle-income countries that now collect a more comprehensive measure of household consumption. Faced with such methodological changes, countries have frequently revised upward their national poverty lines to make them appropriate for the new measures of consumption. This in turn affects the World Bank’s global poverty lines when they are periodically revised. The international poverty line, which is based on the typical poverty line in low-income countries, increases by around 40 percent to $3.00 when the more recent national poverty lines as well as the 2021 purchasing power parities are incorporated. The net impact of the changes in international prices, the poverty line, and new survey data (including new data for India) is an increase in global extreme poverty by some 125 million people in 2022, and a significant shift of poverty away from South Asia and toward Sub-Saharan Africa. The changes at higher poverty lines, which are more relevant to middle-income countries, are mixed.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 Gender Gaps in the Performance of Small Firms: Evidence from Urban Peru(Washington, DC: World Bank, 2025-09-23)This paper estimates the gender gap in the performance of firms in Peru using representative data on both formal and informal firms. On average, informal female-led firms have lower sales, labor productivity, and profits compared to their male-led counterparts, with differences more pronounced when controlling for observable determinants of firm performance. However, gender gaps are only significant at the bottom of the performance distribution of informal firms, and these gaps disappear at the top of the distribution of informal firms and for formal firms. Possible explanations for the performance gaps at the bottom of the distribution include the higher likelihood of small, female-led firms being home-based, which is linked to lower profits, and their concentration in less profitable sectors. The paper provides suggestive evidence that household responsibilities play a key role in explaining the gender gap in firm performance among informal firms. Therefore, policies that promote access to care services or foster a more equal distribution of household activities may reduce gender productivity gaps and allow for a more efficient allocation of resources.Publication The Exposure of Workers to Artificial Intelligence in Low- and Middle-Income Countries(Washington, DC: World Bank, 2025-02-05)Research on the labor market implications of artificial intelligence has focused principally on high-income countries. This paper analyzes this issue using microdata from a large set of low- and middle-income countries, applying a measure of potential artificial intelligence occupational exposure to a harmonized set of labor force surveys for 25 countries, covering a population of 3.5 billion people. The approach advances work by using harmonized microdata at the level of individual workers, which allows for a multivariate analysis of factors associated with exposure. Additionally, unlike earlier papers, the paper uses highly detailed (4 digit) occupation codes, which provide a more reliable mapping of artificial intelligence exposure to occupation. Results within countries, show that artificial intelligence exposure is higher for women, urban workers, and those with higher education. Exposure decreases by country income level, with high exposure for just 12 percent of workers in low-income countries and 15 percent of workers in lower-middle-income countries. Furthermore, lack of access to electricity limits effective exposure in low-income countries. These results suggest that for developing countries, and in particular low-income countries, the labor market impacts of artificial intelligence will be more limited than in high-income countries. While greater exposure to artificial intelligence indicates larger potential for future changes in certain occupations, it does not equate to job loss, as it could result in augmentation of worker productivity, automation of some tasks, or both.Publication Geopolitical Risks and Trade(Washington, DC: World Bank, 2025-09-23)This paper studies the impact of geopolitical risks on international trade, using the Geopolitical Risk (GPR) index of Caldara and Iacoviello (2022) and an empirical gravity model. The impact of spikes in geopolitical risk on trade is negative, strong, and heterogeneous across sectors. The findings show that increases in geopolitical risk reduce trade by about 30 to 40 percent. These effects are equivalent to an increase of global tariffs of up to 14 percent. Services trade is most vulnerable to geopolitical risks, followed by agriculture, and the impact on manufacturing trade is moderate. These negative effects are partially mitigated by cultural and geographic proximity, as well as by the presence of trade agreements.

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 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 Lebanon Economic Monitor, Fall 2022(Washington, DC, 2022-11)The economy continues to contract, albeit at a somewhat slower pace. Public finances improved in 2021, but only because spending collapsed faster than revenue generation. Testament to the continued atrophy of Lebanon’s economy, the Lebanese Pound continues to depreciate sharply. The sharp deterioration in the currency continues to drive surging inflation, in triple digits since July 2020, impacting the poor and vulnerable the most. An unprecedented institutional vacuum will likely further delay any agreement on crisis resolution and much needed reforms; this includes prior actions as part of the April 2022 International Monetary Fund (IMF) staff-level agreement (SLA). Divergent views among key stakeholders on how to distribute the financial losses remains the main bottleneck for reaching an agreement on a comprehensive reform agenda. Lebanon needs to urgently adopt a domestic, equitable, and comprehensive solution that is predicated on: (i) addressing upfront the balance sheet impairments, (ii) restoring liquidity, and (iii) adhering to sound global practices of bail-in solutions based on a hierarchy of creditors (starting with banks’ shareholders) that protects small depositors.Publication Argentina Country Climate and Development Report(World Bank, Washington, DC, 2022-11)The Argentina Country Climate and Development Report (CCDR) explores opportunities and identifies trade-offs for aligning Argentina’s growth and poverty reduction policies with its commitments on, and its ability to withstand, climate change. It assesses how the country can: reduce its vulnerability to climate shocks through targeted public and private investments and adequation of social protection. The report also shows how Argentina can seize the benefits of a global decarbonization path to sustain a more robust economic growth through further development of Argentina’s potential for renewable energy, energy efficiency actions, the lithium value chain, as well as climate-smart agriculture (and land use) options. Given Argentina’s context, this CCDR focuses on win-win policies and investments, which have large co-benefits or can contribute to raising the country’s growth while helping to adapt the economy, also considering how human capital actions can accompany a just transition.Publication Morocco Economic Update, Winter 2025(Washington, DC: World Bank, 2025-04-03)Despite the drought causing a modest deceleration of overall GDP growth to 3.2 percent, the Moroccan economy has exhibited some encouraging trends in 2024. Non-agricultural growth has accelerated to an estimated 3.8 percent, driven by a revitalized industrial sector and a rebound in gross capital formation. Inflation has dropped below 1 percent, allowing Bank al-Maghrib to begin easing its monetary policy. While rural labor markets remain depressed, the economy has added close to 162,000 jobs in urban areas. Morocco’s external position remains strong overall, with a moderate current account deficit largely financed by growing foreign direct investment inflows, underpinned by solid investor confidence indicators. Despite significant spending pressures, the debt-to-GDP ratio is slowly declining.Publication World Development Report 2006(Washington, DC, 2005)This year’s Word Development Report (WDR), the twenty-eighth, looks at the role of equity in the development process. It defines equity in terms of two basic principles. The first is equal opportunities: that a person’s chances in life should be determined by his or her talents and efforts, rather than by pre-determined circumstances such as race, gender, social or family background. The second principle is the avoidance of extreme deprivation in outcomes, particularly in health, education and consumption levels. This principle thus includes the objective of poverty reduction. The report’s main message is that, in the long run, the pursuit of equity and the pursuit of economic prosperity are complementary. In addition to detailed chapters exploring these and related issues, the Report contains selected data from the World Development Indicators 2005‹an appendix of economic and social data for over 200 countries. This Report offers practical insights for policymakers, executives, scholars, and all those with an interest in economic development.
