Abstract
This paper analyzes Zambian export patterns using a new transaction-level trade data set for the period 1999-2011. The data show that, in international comparison, Zambian exports are exceptionally concentrated (on mining products). This reliance has been increasing in recent years. Zambia's exports are also characterized by a high level of churning of firms and products. Multivariate models of survival probabilities suggest that exchange rate volatility and difficult access to imported inputs significantly inhibit diversified and stable exports. The econometric analysis is complemented with a qualitative study of the Zambian export sector. The analysis concludes that one of the main policy levers for unleashing Zambia's full potential as an exporter is by facilitating access to imported inputs. Additional measures that ease foreign exchange transactions, simplify export and certification requirements, and increase the predictability of Zambia's trade regime could be effective to promote Zambia's nontraditional exports.

Publication The Economic Value of Weather Forecasts: A Quantitative Systematic Literature Review(Washington, DC: World Bank, 2025-09-10)This study systematically reviews the literature that quantifies the economic benefits of weather observations and forecasts in four weather-dependent economic sectors: agriculture, energy, transport, and disaster-risk management. The review covers 175 peer-reviewed journal articles and 15 policy reports. Findings show that the literature is concentrated in high-income countries and most studies use theoretical models, followed by observational and then experimental research designs. Forecast horizons studied, meteorological variables and services, and monetization techniques vary markedly by sector. Estimated benefits even within specific subsectors span several orders of magnitude and broad uncertainty ranges. An econometric meta-analysis suggests that theoretical studies and studies in richer countries tend to report significantly larger values. Barriers that hinder value realization are identified on both the provider and user sides, with inadequate relevance, weak dissemination, and limited ability to act recurring across sectors. Policy reports rely heavily on back-of-the-envelope or recursive benefit-transfer estimates, rather than on the methods and results of the peer-reviewed literature, revealing a science-to-policy gap. These findings suggest substantial socioeconomic potential of hydrometeorological services around the world, but also knowledge gaps that require more valuation studies focusing on low- and middle-income countries, addressing provider- and user-side barriers and employing rigorous empirical valuation methods to complement and validate theoretical models.Publication The State of Global Services Trade Policies: Evidence from Recent Data(Washington, DC: World Bank, 2025-10-28)The economic environment for services trade has changed dramatically over the past 15 years, driven by rapid technological progress that has expanded the possibilities for exchanging services. How has trade policy responded to these changes? How do policy stances in a wide range of service sectors compare across economies? With its unprecedented global coverage, the Services Trade Policy Database and the associated Services Trade Restrictions Index, developed jointly by the World Bank and the World Trade Organization, help address these questions. This paper makes three principal contributions. First, it offers an in-depth discussion of the current state of services trade policies and their differences across 134 economies and 34 services subsectors. Second, the paper reveals how recent (2016–22) changes in policy stances have seen progressive liberalization by lower-income economies but stabilization or even slight policy reversals in high-income economies. This dynamic differs fundamentally from the trend that unfolded after the Great Recession over 2008–16. Third, the paper shows the implications of policy changes over the past six years on services trade costs, and it showcases how the Services Trade Policy Database’s regulatory information can inform trade negotiations, regulatory analysis, and policy making. Alongside these contributions, the paper documents updates to the Services Trade Policy Database’s economy and sector coverage and explains the latest methodological improvements made to the World Bank–World Trade Organization Services Trade Restrictions Index.Publication It’s Not (Just) the Tariffs: Rethinking Non-Tariff Measures in a Fragmented Global Economy(Washington, DC: World Bank, 2025-10-22)As tariffs have declined, non-tariff measures (NTMs) have become central to trade policy, especially in high-income countries and regulated sectors like food and green technologies. Although NTMs may serve legitimate goals, they could also sort countries and firms into or out of markets based on compliance capacity and differences in product mix. Documenting recent advances in the estimation of ad valorem equivalents (AVEs), this paper uncovers new patterns of use and exposure of NTMs. High-income countries rely more heavily on NTMs relative to tariffs, while low- and middle-income countries face steeper AVEs on their exports. Firm-level evidence shows that NTMs disproportionately affect smaller firms, leading to market exit and concentration. Poorly designed NTMs can harm productivity and welfare, while coordinated, capacity-aware use can deliver inclusive outcomes. Policy design, transparency, and diagnostics must evolve to reflect the growing role—and risks—of NTMs in a fragmented global trade landscape.Publication The Marshall Plan: Then and Now(Washington, DC: World Bank, 2025-10-14)This paper is a product of the Development Policy Team, Development Economics. It is part of a larger effort by the World Bank to provide open access to its research and make a contribution to development policy discussions around the world.

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 Financial Liberalization and Allocative Efficiency of Capital(2011-05-01)Financial liberalization may have a positive effect on growth not only through the increase in the quantity of the available funds, but also through a more efficient allocation of resources across firms and sectors. Despite this intuitive appeal, there is little empirical evidence on the positive effect of financial liberalization on capital allocation. The main difficulty of investigating the linkage between liberalization of financial markets and capital allocation efficiency lies in the fact that the efficiency of capital allocation is not directly observable. One way to address this issue is to evaluate the effect of financial liberalization within the Heckscher-Ohlin framework. Producing and exporting products inconsistent with a country's factor endowments constitutes a serious misallocation of the funds, which undermines competitiveness of the economy and inhibits its long run growth. This paper tests the allocative efficiency hypothesis by evaluating the effect of stock market liberalization on the survival of different product categories using export data for 91 countries over the period of 1975-2003. Preliminary results suggest that after liberalization of the domestic stock market, products employing intensively scarce factors exit at a relatively higher rate from a country's export portfolio. In other words, following liberalization episodes, a country tends to rebalance its export portfolio towards products consistent with its factor's endowments.Publication Patterns of Foreign Direct Investment Flows and Trade-Investment Inter-Linkages in Southern Africa : Linking Middle-Income and Low-Income Neighbors(World Bank, Washington, DC, 2010-05)This report discusses the patterns of foreign direct investment flows and trade-investment inter-linkages in Southern Africa. It will discuss how cross-border investment flows create a possible channel of growth spillover from South Africa and other MICs to LICs in the subregion, and identify the roles of subregional trade and investment flows in generating these neighborhood effects with LICs. After an introduction with background on the subregion of Southern Africa, Section 2 provides facts on the patterns of trade in Southern African countries to illustrate how much (or little) the Southern African subregion is integrated today and whether or not intraregional trade is growing. Section 3 presents aggregate trends in foreign direct investment flows (and stocks) in SSA, discusses how SASR is situated in such trends, and analyzes the emerging trends of intra-SASR cross-border investments, largely driven by South Africa. Section 4 analyzes trade-investment linkages in Southern Africa at the firm level. Section 5 discusses areas of domestic policies in enhancing trade and foreign direct investment in Southern Africa. Section 6 summarizes the findings from this analysis and discusses their policy implications.Publication ASEAN Integration Monitoring Report(Jakarta: ASEAN Secretariat and the World Bank, 2013)The Association of Southeast Asian Nations (ASEAN) is a community of more than 600 million people living in ten countries in one of the most dynamic regions of the world. Consistent with this, ASEAN's share of world GDP and world trade has sharply increased over the past decades. In 2003, ASEAN's regional integration agenda was significantly deepened when ASEAN Member States adopted the ambitious goal of forming an ASEAN Economic Community (AEC) by 2015. These goals were crystallized in the highly specific targets set for creating a 'single market and production base' in the ASEAN Economic Community Blueprint of 2007, signed by the Heads of the Governments of the ASEAN countries. The focus of the report is on policy and market integration outcomes achieved in ASEAN Member States (AMS) as part of the Pillar One of the ASEAN Economic Community (AEC) formation process. The aim is to assess progress drawing on evidence from a large range of indicators on policies and outcomes. The report then suggests priorities for future actions for implementing the AEC 2015 goals. This report is based on the inception report presented to and endorsed by the Senior Economic Officials' Meetings of the ASEAN last year and on the presentation on early findings also to the SEOM. The earlier version of this report was also presented to the 45th ASEAN Economic Ministers' Meetings in Bandar Seri Begawan, Brunei Darussalam in August 2013. This report is intended to complement the recent mid-term review report by the Economic Research Institute for ASEAN and East Asia (ERIA, 2012), which has focused more on progress with agreements and commitments for achieving AEC 2015 goals.Publication World Trade Indicators 2008 : Benchmarking Policy and Performance(Washington, DC : World Bank, 2008)The World Trade Indicators (WTI) database and ranking tool cover country level indicators of trade performance and policies and institutions that affect trade. The purpose of this initiative by the World Bank is to benchmark progress in these areas while highlighting important data gaps. The value of timely, good-quality data for policy making and effective international negotiations cannot be underestimated. Such data are also needed for reducing transactions costs for businesses. This publication summarizes patterns in world trade policy and trade outcomes revealed by the WTI database, focusing mainly on regional and income level variations and providing the context to help evaluate individual country progress. It is hoped that this initiative, by benchmarking country performance in various policy and outcome areas, will enhance the ability of policy makers to design and implement needed trade-related reforms. It is also hoped that countries will be further encouraged to produce better and more up to date data and make it publicly available, both domestically and in international databases, in a timely manner.Publication Trade Policy Reform in the East Asian Transition Economies(World Bank, Washington, DC, 2001-01)The performance of the East Asian transition economies in export and income growth has been strikingly better than that of countries in Eastern Europe and the former Soviet Union. The East Asian economies have achieved remarkably high growth rates in outputs and exports without the often large declines in output and exports observed in Eastern Europe and the former Soviet Union. East Asian reformers have successfully made many of the parallel changes needed in both domestic and trade policies to secure export and income growth. (It makes no sense, for example, to introduce the trade policy instruments of a market economy when the domestic economy is still based on central planning.) But there has been no single magic formula for their success. The author discusses what each of the economies (Cambodia, China, Lao People's Democratic Republic, and Vietnam) has done. China experienced an extended transition process; the transition ws much shorter in other East Asian transition economies--especially Cambodia. Several of the East Asian transition economies used accession to a regional arrangement as part of their reform strategy. China focused mainly on unilateral reforms and, more recently, reforms associated with its accession to the World Trade Organization. Most have made extensive use of policies to attract foreign investment and to mitigate the burden of protection on manufacturing exporters. Most of the remaining trade policy problems, although difficult, appear to be problems more of development than of transition.

Publication Business Ready 2024(Washington, DC: World Bank, 2024-10-03)Business Ready (B-READY) is a new World Bank Group corporate flagship report that evaluates the business and investment climate worldwide. It replaces and improves upon the Doing Business project. B-READY provides a comprehensive data set and description of the factors that strengthen the private sector, not only by advancing the interests of individual firms but also by elevating the interests of workers, consumers, potential new enterprises, and the natural environment. This 2024 report introduces a new analytical framework that benchmarks economies based on three pillars: Regulatory Framework, Public Services, and Operational Efficiency. The analysis centers on 10 topics essential for private sector development that correspond to various stages of the life cycle of a firm. The report also offers insights into three cross-cutting themes that are relevant for modern economies: digital adoption, environmental sustainability, and gender. B-READY draws on a robust data collection process that includes specially tailored expert questionnaires and firm-level surveys. The 2024 report, which covers 50 economies, serves as the first in a series that will expand in geographical coverage and refine its methodology over time, supporting reform advocacy, policy guidance, and further analysis and research.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 Digital Progress and Trends Report 2023(Washington, DC: World Bank, 2024-03-05)Digitalization is the transformational opportunity of our time. The digital sector has become a powerhouse of innovation, economic growth, and job creation. Value added in the IT services sector grew at 8 percent annually during 2000–22, nearly twice as fast as the global economy. Employment growth in IT services reached 7 percent annually, six times higher than total employment growth. The diffusion and adoption of digital technologies are just as critical as their invention. Digital uptake has accelerated since the COVID-19 pandemic, with 1.5 billion new internet users added from 2018 to 2022. The share of firms investing in digital solutions around the world has more than doubled from 2020 to 2022. Low-income countries, vulnerable populations, and small firms, however, have been falling behind, while transformative digital innovations such as artificial intelligence (AI) have been accelerating in higher-income countries. Although more than 90 percent of the population in high-income countries was online in 2022, only one in four people in low-income countries used the internet, and the speed of their connection was typically only a small fraction of that in wealthier countries. As businesses in technologically advanced countries integrate generative AI into their products and services, less than half of the businesses in many low- and middle-income countries have an internet connection. The growing digital divide is exacerbating the poverty and productivity gaps between richer and poorer economies. The Digital Progress and Trends Report series will track global digitalization progress and highlight policy trends, debates, and implications for low- and middle-income countries. The series adds to the global efforts to study the progress and trends of digitalization in two main ways: · By compiling, curating, and analyzing data from diverse sources to present a comprehensive picture of digitalization in low- and middle-income countries, including in-depth analyses on understudied topics. · By developing insights on policy opportunities, challenges, and debates and reflecting the perspectives of various stakeholders and the World Bank’s operational experiences. This report, the first in the series, aims to inform evidence-based policy making and motivate action among internal and external audiences and stakeholders. The report will bring global attention to high-performing countries that have valuable experience to share as well as to areas where efforts will need to be redoubled.Publication The Container Port Performance Index 2023(Washington, DC: World Bank, 2024-07-18)The Container Port Performance Index (CPPI) measures the time container ships spend in port, making it an important point of reference for stakeholders in the global economy. These stakeholders include port authorities and operators, national governments, supranational organizations, development agencies, and other public and private players in trade and logistics. The index highlights where vessel time in container ports could be improved. Streamlining these processes would benefit all parties involved, including shipping lines, national governments, and consumers. This fourth edition of the CPPI relies on data from 405 container ports with at least 24 container ship port calls in the calendar year 2023. As in earlier editions of the CPPI, the ranking employs two different methodological approaches: an administrative (technical) approach and a statistical approach (using matrix factorization). Combining these two approaches ensures that the overall ranking of container ports reflects actual port performance as closely as possible while also being statistically robust. The CPPI methodology assesses the sequential steps of a container ship port call. ‘Total port hours’ refers to the total time elapsed from the moment a ship arrives at the port until the vessel leaves the berth after completing its cargo operations. The CPPI uses time as an indicator because time is very important to shipping lines, ports, and the entire logistics chain. However, time, as captured by the CPPI, is not the only way to measure port efficiency, so it does not tell the entire story of a port’s performance. Factors that can influence the time vessels spend in ports can be location-specific and under the port’s control (endogenous) or external and beyond the control of the port (exogenous). The CPPI measures time spent in container ports, strictly based on quantitative data only, which do not reveal the underlying factors or root causes of extended port times. A detailed port-specific diagnostic would be required to assess the contribution of underlying factors to the time a vessel spends in port. A very low ranking or a significant change in ranking may warrant special attention, for which the World Bank generally recommends a detailed diagnostic.Publication Global Economic Prospects, January 2025(Washington, DC: World Bank, 2025-01-16)Global growth is expected to hold steady at 2.7 percent in 2025-26. However, the global economy appears to be settling at a low growth rate that will be insufficient to foster sustained economic development—with the possibility of further headwinds from heightened policy uncertainty and adverse trade policy shifts, geopolitical tensions, persistent inflation, and climate-related natural disasters. Against this backdrop, emerging market and developing economies are set to enter the second quarter of the twenty-first century with per capita incomes on a trajectory that implies substantially slower catch-up toward advanced-economy living standards than they previously experienced. Without course corrections, most low-income countries are unlikely to graduate to middle-income status by the middle of the century. Policy action at both global and national levels is needed to foster a more favorable external environment, enhance macroeconomic stability, reduce structural constraints, address the effects of climate change, and thus accelerate long-term growth and development.
