Abstract
Large-scale transport infrastructure investment can facilitate structural transformation by changing firm behavior. Although its impact is evident over the long term, an important empirical challenge is potential endogeneity of infrastructure placement. By using the dynamic panel data regression, the paper examines the impacts of massive road corridor investment under the Nurly Zhol program in Kazakhstan. The paper takes advantage of detailed micro shipping data to capture historical changes in transport connectivity over the past 10 years. While the average travel speed has slightly increased, transport costs have been nearly halved. The estimated translog cost functions indicate that local market accessibility is the most important factor to boost firm productivity. The elasticity was 0.24 in absolute terms. Inventory is found to be a major cost factor for firms. It is found that a 10-percent improvement in accessibility to large cities, such as Astana and Almaty, could allow firms to reduce their inventory by 8.7 percent. The market accessibility is found to foster firm agglomerations, but agglomeration economies do not seem to translate into higher firm productivity. This is possibly because the Kazakh economy still lacks effective forward or backward linkages across industries.

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 Firms’ Locational Choice and Infrastructure Development in Tanzania(World Bank, Washington, DC, 2015-06)Agglomeration economies are among the most important factors in increasing firm productivity. However, there is little evidence supportive of this in Africa. Using the firm registry database in Tanzania, this paper examines a new application of the logit approach with two empirical issues taken into account: spatial autocorrelation and endogeneity of infrastructure placement. The paper finds significant agglomeration economies. It is also found that firms are more likely to be located where local connectivity and access to markets are good. The paper finds that dealing with infrastructure endogeneity and spatial autocorrelation in the empirical model is important. According to the exogeneity test, infrastructure variables are likely endogenous. The spatial autoregressive term is significant. As expected, therefore, there are positive externalities of firm location choice around the neighboring areas.Publication Agglomeration Economies and Transport Connectivity Revisited(World Bank, Washington, DC, 2023-08-02)Transport connectivity is an important determinant of agglomeration economies and urbanization. However, measuring its impacts is a complex task when causality is considered. An important empirical challenge comes from potential endogeneity of infrastructure placement. To deal with the endogeneity problem, first, the paper constructs detailed georeferenced connectivity measurements based on micro shipping data collected over 10 years. Then, the system generalized method of moments regression is applied. Using unique data from the Caucasus and Central Asian countries, the paper estimates the impact of transport connectivity on agglomeration economies. It finds that agglomeration economies are significant and persistent in the region. Thus, the existing firm clusters are likely to continue growing. However, a constraint is also found. Large cities exhibit congestion diseconomies. Finally, the paper shows that the improvement of transport connectivity, especially local market accessibility, has a significant effect on agglomeration. By contrast, no clear evidence to support the impact of improved regional connectivity on agglomeration is observed yet. To take full advantage of agglomeration economies at the regional level, further efforts may be needed, for instance, toward increasing efficiency in transportation and logistics, improving the freight load, and/or reducing the time and costs of border crossing, which add to overall transport costs and times.Publication What is Missing Between Agricultural Growth and Infrastructure Development? Cases of Coffee and Dairy in Africa(World Bank, Washington, DC, 2007-11)Although it is commonly believed that aggregate economic growth must be associated with public infrastructure stocks, the possible infrastructure needs and effects are different from industry to industry. The agriculture sector is typical. Various infrastructures would affect agriculture growth differently depending on the type of commodity. This paper finds that a general transport network is essential to promote coffee and cocoa production, perhaps along with irrigation facilities, depending on local rainfall. Conversely, along with the transport network, the dairy industry necessitates rural water supply services as well. In some African countries, a 1 percent improvement in these key aspects of infrastructure could raise GDP by about 0.1-0.4 percent, and by possibly by several percent in some cases.Publication Infrastructure and Economic Development in Sub-Saharan Africa(World Bank, Washington, DC, 2008-09)An adequate supply of infrastructure services has long been viewed by both academics and policy makers as a key ingredient for economic development. Sub-Saharan Africa ranks consistently at the bottom of all developing regions in terms of infrastructure performance, and an increasing number of observers point to deficient infrastructure as a major obstacle for growth and poverty reduction across the region. This paper offers an empirical assessment of the impact of infrastructure development on growth and inequality, with a focus on Sub-Saharan Africa. The paper uses a comparative cross-regional perspective to place Africa's experience in the international context. Drawing from an updated data set of infrastructure quantity and quality indicators covering more than 100 countries and spanning the years 1960-2005, the paper estimates empirical growth and inequality equations including a standard set of control variables augmented by infrastructure quantity and quality measures, and controlling for the potential endogeneity of the latter. The estimates illustrate the potential contribution of infrastructure development to growth and equity across Africa.Publication Improving Logistics Costs for Transportation and Trade Facilitation(World Bank, Washington, DC, 2008-03)Access to basic infrastructure services - roads, electricity, water, sanitation - and the efficient provision of the services, is a key challenge in the fight against poverty. Many of the poor (and particularly the extreme poor) in rural communities in Latin America live on average 5 kilometers or more from the nearest paved road, which is almost twice as far as non-poor rural households. There have been major improvements in access to water, sanitation, electricity, telecommunications, ports, and airports, but road coverage has not changed much, although some effort and resources have been invested to improve the quality of road networks. This paper focuses on the main determinants of logistics costs and physical access to services and, whenever possible, provides evidence of the effects of these determinants on competitiveness, growth, and poverty in Latin American economies. The analysis shows the impact of improving infrastructure and logistics costs on three fronts - macro (growth), micro (productivity at the firm level), and poverty (the earnings of poor/rural people). In addition, the paper provides recommendations and solutions that encompass a series of policies to reduce the prevalent high logistics costs and limited access to services in Latin America. The recommendations rely on applied economic analysis on logistics and trade facilitation.

Publication World Bank East Asia and Pacific Economic Update, October 2025: Jobs(Washington, DC: World Bank, 2025-10-07)GDP growth in the East Asia and Pacific (EAP) region remains above the global average but is projected to slow down in 2025 and even further in 2026. The sluggishness is due to a less favorable external environment—rising trade restrictions, easing but still elevated global uncertainty, and slowing global growth—as well as persistent domestic difficulties. Today, many people are in low-productivity or informal jobs, and many of the young cannot find any jobs. The class of people vulnerable to falling into poverty is now larger than the middle class in most countries. In a region that thrived because export-oriented, labor-intensive growth created more productive jobs, firms must deal with higher tariffs and workers must contend with the growing use of robots, AI and digital platforms. More productive jobs would be created by reforms to enhance economic opportunity, human capacity and their virtuous interplay.Publication Safety First(World Bank, Washington, DC, 2021-07)This paper examines the long-term consequences of unsafe public spaces for women. It combines student-level survey data, a mapping of potential travel routes to all the colleges in the choice set, and crowdsourced mobile application safety data from Delhi. The findings show that women choose a college in the bottom half of the quality distribution over a college in the top quintile to feel safer while traveling, relative to men with comparable choice sets who choose a college in the top one-third of the distribution over a college in the top quintile. These findings have implications beyond women’s human capital attainment, such as their participation in the labor force.Publication Commodity Markets Outlook, October 2025(Washington, DC: World Bank, 2025-10-29)Commodity prices are expected to decline by about 7 percent overall this year, reflecting subdued global economic activity, elevated trade tensions and policy uncertainty, ample global supply of oil, and weather-related supply shocks. In 2026, commodity prices are forecast to fall by a further 7 percent, a fourth consecutive year of decline, as global growth remains sluggish and the oil market oversupplied. Energy price movements are envisaged to continue contributing to global disinflation in 2026. Metals and minerals prices are expected to remain stable in 2026, while agricultural prices are projected to edge down, primarily due to strong supply conditions. Precious metals prices are expected to rise another 5 percent, after a historically large, investment-driven rally of about 40 percent in 2025. Risks to the commodity price projections are tilted to the downside. Key downside risks include weaker-than-expected global growth, a longer-than-assumed period of economic policy uncertainty, and additional oversupply of oil. Upside risks include intensifying geopolitical tensions, the market impact of additional oil sanctions, supply reductions stemming from additional trade restrictions, unfavorable weather conditions, faster-than-expected rollout of new data centers. Commodity price volatility in recent years has revived interest in supply management via international commodity agreements. Historical experience, however, shows that the most effective policy is to promote diversification, innovation, transparency, and market-based pricing—measures that build lasting resilience to commodity price volatility.Publication Global Economic Prospects, June 2025(Washington, DC: World Bank, 2025-06-10)The global economy is facing another substantial headwind, emanating largely from an increase in trade tensions and heightened global policy uncertainty. For emerging market and developing economies (EMDEs), the ability to boost job creation and reduce extreme poverty has declined. Key downside risks include a further escalation of trade barriers and continued policy uncertainty. These challenges are exacerbated by subdued foreign direct investment into EMDEs. Global cooperation is needed to restore a more stable international trade environment and scale up support for vulnerable countries grappling with conflict, debt burdens, and climate change. Domestic policy action is also critical to contain inflation risks and strengthen fiscal resilience. To accelerate job creation and long-term growth, structural reforms must focus on raising institutional quality, attracting private investment, and strengthening human capital and labor markets. Countries in fragile and conflict situations face daunting development challenges that will require tailored domestic policy reforms and well-coordinated multilateral support.Publication Future Jobs: Robots, Artificial Intelligence, and Digital Platforms in East Asia and Pacific(Washington, DC: World Bank, 2025-05-19)People in East Asia and Pacific (EAP) countries have prospered over the last few decades because of the growth in productive jobs. Do industrial robots, artificial intelligence (AI), and digital platforms threaten that development model? "Future Jobs" presents evidence that new technologies have thus far boosted employment. Increases in productivity and scale have outweighed the labor-displacing effects of automation technologies. However, the benefits have been uneven, favoring skilled workers while some less-skilled workers, in more routine and manual jobs, have been pushed into the informal sector. Digital platforms have generated new opportunities for the hitherto marginalized but also created insecurity for incumbent workers. Looking ahead, digitization will enhance the tradability of services, and AI will transform the production processes. EAP countries can benefit by equipping their workforce with the necessary skills and opening their long-protected services sectors to trade and investment. Policy makers, researchers, and businesses will find in this book both insights and questions on how best to harness the potential of new technologies to sustain prosperity in EAP countries.
