Abstract
This paper characterizes the firm size distribution by exploiting establishment-level censuses covering both formal and informal firms in Sub-Saharan Africa. The paper finds a "missing middle" in the employment-based size distribution of firms in four Sub-Saharan African countries. This "missing middle" hinges on the inclusion of informal firms, and it is not explained by state- or foreign-owned firms at the top of the size distribution, nor does it emerge from the size distribution of entrants. The paper reconciles these empirical results with a model of firm dynamics with endogenous informality and shows that calibrated values of entry barriers and productivity-dependent idiosyncratic distortions generate a "missing middle" that is consistent with its underlying drivers in the data.

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 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 The Evolution of Local Participatory Democracy in Nepal(Washington, DC: World Bank, 2025-11-05)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.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 Closing the Gender Gap in Entrepreneurship: Overcoming Challenges in Law and Practice for Female Entrepreneurs(Washington, DC: World Bank, 2026-01-07)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.

Publication Taxing the Good? Distortions, Misallocation, and Productivity in Sub-Saharan Africa(Published by Oxford University Press on behalf of the World Bank, 2020-02)This paper uses comprehensive and comparable firm-level manufacturing censuses from four Sub-Saharan African (SSA) countries to examine the extent, costs, and nature of within-industry resource misallocation between heterogeneous production units. This paper finds evidence of severe misallocation in which resources are diverted away from high-productivity firms towards low-productivity ones, although the magnitude differs across countries. Estimated aggregate productivity gains from the hypothetical equalization of marginal returns range from 30 percent in Côte d’Ivoire to 160 percent in Kenya. The magnitude of reallocation gains appears considerably lower when performing the same counterfactual exercise based on the World Bank Enterprise Surveys once the value-added shares of industries are adjusted using the census data. This suggests that linking firm-level survey data to aggregate outcomes requires census-type data or sampling methods that take the true structure of production into account.Publication Taxing the Good? Distortions, Misallocation, and Productivity in Sub-Saharan Africa(World Bank, Washington, DC, 2017-01)This paper uses comprehensive and comparable firm-level manufacturing census data from four Sub-Saharan African countries to examine the extent, costs, and nature of within-industry resource misallocation across heterogeneous firms. The paper finds evidence of severe misallocation in which resources are diverted away from high-productivity firms toward low-productivity ones in all four countries, although the magnitude differs across countries. The paper shows that a hypothetical reallocation of resources that equalizes marginal returns across firms would increase manufacturing productivity by 31.4 percent in Cote d'Ivoire and as much as 162.7 percent in Kenya. The paper emphasizes the importance of the quality of the underlying data, by comparing the results against those from the World Bank Enterprise Surveys. The comparison finds that the survey-based results underestimate the extent of misallocation vis-a-vis the census. Finally, the paper finds that the size of existing distortions is correlated with various measures of business environment, such as lack of access to finance, corruption, and regulations.Publication Unmasking the Impact of COVID-19 on Businesses(World Bank, Washington, DC, 2020-10)This paper provides a comprehensive assessment of the short-term impact of the COVID-19 pandemic on businesses worldwide with a focus on developing countries. The results are based on a novel data set collected by the World Bank Group and several partner institutions in 51 countries covering more than 100,000 businesses. The paper provides several stylized facts. First, the COVID-19 shock has been severe and widespread across firms, with persistent negative impact on sales. Second, the employment adjustment has operated mostly along the intensive margin (that is leave of absence and reduction in hours), with a small share of firms laying off workers. Third, smaller firms are disproportionately facing greater financial constraints. Fourth, firms are increasingly relying on digital solutions as a response to the shock. Fifth, there is great uncertainty about the future, especially among firms that have experienced a larger drop in sales, which is associated with job losses. These findings provide a better understanding of the magnitude and distribution of the shock, the main channels affecting businesses, and how firms are adjusting. The paper concludes by discussing some avenues for future research.Publication Policies to Support Businesses through the COVID-19 Shock(World Bank, Washington, DC, 2021-01)Relying on a novel dataset covering more than 120,000 firms in 60 countries, this paper con-tributes to the debate about D policies to support businesses through the COVID-19 pandemic. While governments around the world have implemented a wide range of policy support measures, evidence on the reach of these policies, the alignment of measures with firm needs, and their targeting and effectiveness remains scarce. This paper provides the most comprehensive assessment to date of these issues, focusing primarily on the developing economies. It shows that policy reach has been limited, especially for the more vulnerable firms and countries, and identifies mismatches between policies provided and policies most sought. It also provides some indicative evidence regarding mistargeting of policies and their effectiveness in addressing liquidity constraints and preventing layoffs. This assessment provides some early guidance to policymakers on tailoring their COVID-19 business support packages and points to new directions in data and research efforts needed to guide policy responses to the current pandemic and future crises.Publication Importing and Firm Productivity in Ethiopian Manufacturing(Published by Oxford University Press on behalf of the World Bank, 2019-10)This paper investigates the causal relationship between importing and firm productivity. Using a rich dataset from Ethiopian manufacturing over the period 1996–2011, I find that most firms rely on production inputs from the world market. These firms are better performing as shown by significant, economically large import premia. I also find strong evidence of self-selection of more productive firms into importing which is indicative of sizable import market entry costs. To examine the causal effect of importing on firm productivity, I use a model in which the static and dynamic effects of importing are separately estimated. The estimation results provide support to learning-by-importing. However, the productivity gains are small in size compared to similar findings in other studies. I provide some evidence in support of firms’ limited absorptive capacity in explaining the small productivity gains.

Publication Reshaping Economic Geography in East Asia(World Bank, 2009)Reshaping economic geography in East Asia illustrates how extensively spatial factors have influenced and informed by growth and development in the region. This study was conceived as a companion volume to and informed by the World Development Report (WDR) 2009: reshaping economic geography. By providing case studies and illustrative examples and by deepening the understanding of the forces of economic geography in the East Asia region, this work helped to substantiate some of the key concepts in the WDR 2009. There is full consistency in terms of the analytical framework used and broad agreement on how economic geography has influenced growth trends across a diverse range of countries. Reshaping economic geography in East Asia also highlights the dramatic urbanization process under way in the region, evidenced by the number of globally recognized 'mega cities'. Seven of the world's 21 mega cities are in East Asia. Cities in East Asia generate about three-quarters of annual output and between a half and two-thirds of exports. Often, much of this is concentrated in one major city: Bangkok. Bangkok accounts for 40 percent of Thailand's gross domestic product (GDP) and Manila for 30 percent. Other major centers such as Guangzhou, Jakarta, Seoul, Shanghai, and Tokyo are seen as driving their economies. East Asian cities have been able to deliver the agglomeration benefits required for growth and are now exceptionally well connected to the global economy. The region, excluding Japan, is home to 16 of the largest 25 seaports in the world and 14 of the largest 25 container ports. Without this improved connectivity, the region's rapid expansion in trade volumes will not have been possible. This collection of studies is organized in four sections. The first section comprises chapters dealing with the 'context and concepts' for this volume. The second deals with Southeast Asia, specifically, the Association of South East Asian Nations (ASEAN) countries. The third deals with Northeast Asia: China and the Republic of Korea, and the fourth section provide an overview of lessons learned. The time perspective for most of the studies spans several decades; in many cases, outcomes and policies can be traced back half a century or more.Publication China : Integration of National Product and Factor Markets, Economic Benefits and Policy Recommendations(Washington, DC, 2005-06)Lack of market integration has been a long-standing concern in China. The existing empirical evidence on the degree and trend in local protectionism and market fragmentation, has painted a mixed picture - some concluding to increasing fragmentation, others pointing at increasing integration. This report uses a comprehensive set of survey data, and a provincial data set to examine the extent and trends in market fragmentation. It finds mixed results across the three key markets in product, labor and capital: Since the early 1990s, the product market is increasingly integrating, with converging prices across the country, and increasing regional specialization. The survey data suggests strongly that regional protectionism declined significantly over the past 10 years. The labor market, while getting more integrated over the reform period, still shows significant fragmentation across regions and across sectors. The remains of the hukou system, the limited access migrants have to social services, and the highly uneven quality of public services reinforce labor market segmentations. The capital markets still show large misallocations in capital across industries, and across China's regions. More significantly, the empirical evidence indicates that the degree of capital market fragmentation has actually increased in the 1990s compared to the 1980s. As China is moving towards a Xiaokang Society, national market integration takes on increasing prominence. Indeed, the gains for China of better integration of goods and factor markets can be huge - much larger than the gains expected from the World Trade Organization (WTO) accession for which the country worked so hard. The report conducts policy simulations to estimate these gains. The report also estimates the economic gains from greater financial market integration. It conducts a simulation by changing the long standing urban bias policy through the movement of investment from cities to rural areas, while keeping the total amount investment constant. As a continental economy, it is time China starts its own determined effort to more rapidly integrate its markets, to maximize efficiency and growth, and ensure that the welfare gains get distributed more evenly across the nation.Publication Government at Risk : Contingent Liabilities and Fiscal Risk(Washington, DC: World Bank and Oxford University Press, 2002)Conventional fiscal analysis fails to address contingent fiscal risk. The government budget process and documentation generally fail to scrutinize the substantial claims on public resources that are associated with government contingent liabilities, realized and potential. This report fills gaps on our understanding of fiscal risks and develops suitable frameworks for managing them. It offers new analytical concepts, presents country case studies, and based on country case studies, provides a menu of practical ideas for policymakers and scholars to bring fiscal risk within the ambit of public finance. The book is divided into two parts: Part I of this book gives an overview of different approaches to dealing with government fiscal risks. The country examples in this part offer additional conceptual approaches and illustrate some of the discussion in the earlier chapters. Part II presents analytical and institutional approaches that governments might consider when facing risks in specific government programs or sectors. The book indicates that countries differ greatly in their treatment of contingent liabilities and other fiscal risks. In this respect, the book illustrates that contemporary practices have yet to be standardized.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 The Right to Tell : The Role of Mass Media in Economic Development(Washington, DC, 2002)A free press is not a luxury. It is at the core of equitable development. The media can expose corruption. They can keep a check on public policy by throwing a spotlight on government action. They let people voice diverse opinions on governance and reform, and help build public consensus to bring about change. Such media help markets work better. They can facilitate trade, transmitting ideas and innovation across boundaries. The media are also important for human development, bringing health and education information to remote villages in countries from Uganda to Nicaragua. But as experience has shown, the independence of the media can be fragile and easily compromised. It is clear that to support development, media need the right environment-in terms of freedoms, capacities, and checks and balances. The World Development Report 2002, "Building Institutions for Markets (rep. no. 22825)," devoted a chapter to the role of the media in development. This volume is an extension of that work. It discusses how media affects development outcomes under different circumstances and presents evidence on what policy environment is needed to enable the media to support economic and political markets and to provide a voice for the disenfranchised. To this end, it draws together the views of academics as well as perspectives from those on the front line-journalists themselves.
