Abstract
This paper discusses compensation mechanisms to strengthen incentives for lower-income countries to adopt carbon taxes through donor-funded support programs. The paper considers two cases: the provision of climate finance when the host country uses the additional mitigation to meet its own greenhouse gas mitigation target (the "incremental cost price"); and a transaction in an international carbon market with the mitigation credit created by host country mitigation transferred outside the country (the “opportunity cost price”). Both offset the host country's deadweight loss from imposing a carbon tax, which is lower when the host country enjoys large co-benefits from mitigation. Formulas are derived for the incremental cost price and the opportunity cost price. The opportunity cost price is always larger than the incremental cost price, as the host country under the opportunity cost price must use additional, more expensive mitigation policies to reach its mitigation target. The paper discusses additional costs and barriers that deter hosts from adopting carbon taxes. These arguments can help to explain why few low-income countries have so far adopted carbon taxes, and why the necessary compensation for tax adoption may exceed theoretical assessments.

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 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 Labor Demand in the Age of Generative AI: Early Evidence from the U.S. Job Posting Data(Washington, DC: World Bank, 2025-11-18)This paper examines the causal impact of generative artificial intelligence on U.S. labor demand using online job posting data. Exploiting ChatGPT’s release in November 2022 as an exogenous shock, the paper applies difference-in-differences and event study designs to estimate the job displacement effects of generative artificial intelligence. The identification strategy compares labor demand for occupations with high versus low artificial intelligence substitution vulnerability following ChatGPT’s launch, conditioning on similar generative artificial intelligence exposure levels to isolate substitution effects from complementary uses. The analysis uses 285 million job postings collected by Lightcast from the first quarter of 2018 to the second quarter of 2025Q2. The findings show that the number of postings for occupations with above-median artificial intelligence substitution scores fell by an average of 12 percent relative to those with below-median scores. The effect increased from 6 percent in the first year after the launch to 18 percent by the third year. Losses were particularly acute for entry-level positions that require neither advanced degrees (18 percent) nor extensive experience (20 percent), as well as those in administrative support (40 percent) and professional services (30 percent). Although generative artificial intelligence generates new occupations and enhances productivity, which may increase labor demand, early evidence suggests that some occupations may be less likely to be complemented by generative artificial intelligence than others.Publication External Finance in Emerging Markets and Developing Economies: A Tale of Differences in Vulnerabilities(Washington, DC: World Bank, 2025-12-04)Over the past two decades, many emerging markets and developing economies have been viewed as increasingly resilient to external financial shocks. This paper assesses whether such resilience is broadly shared across emerging markets and developing economies by classifying them into three tiers based on economic size, income level, institutional strength, and financial integration. The analysis shows that first-tier emerging markets and developing economies have improved their external balance sheets and reduced dependence on official support. However, second- and third-tier emerging markets and developing economies have experienced growing external vulnerabilities since the global financial crisis, marked by rising external debt liabilities and declining foreign exchange reserves. Using a range of indicators, including sovereign defaults, arrears, partial defaults, and International Monetary Fund lending, the paper identifies episodes of external financial distress and shows that distress remains widespread among second- and third-tier emerging markets and developing economies. The empirical analysis confirms that key components of the net international investment position—especially external debt and foreign exchange reserves—predict the onset of external financial distress, with institutional quality shaping the impact. Weak institutions amplify risks, while strong institutions mitigate them. These findings highlight the importance of recognizing heterogeneity across emerging markets and developing economies, strengthening institutional quality alongside external balance-sheet management, and rebuilding buffers to safeguard against renewed global financial stress.Publication Rigging the Scores: Corruption through Scoring Rule Manipulation in Public Procurement Auctions(Washington, DC: World Bank, 2025-12-02)Public procurement is highly susceptible to corruption, especially in developing countries. Although open auctions are widely adopted to curb it, this paper finds that corruption remains prevalent even within this procurement format. Procurement officers can collaborate with firms to manipulate scoring rules, ensuring predetermined winners, while corrupt firms submit noncompetitive bids to meet minimum bidder requirements. Using extensive data from Chinese public procurement auctions, the paper introduces model-driven statistical tools to detect such corruption, identifying a corruption rate of 65 percent. A procurement expert audit survey confirms the tools’ reliability, with a 91 percent probability that experts recognize suspicious scoring rules when flagged. Firm-level analysis reveals that local, state-owned, and less productive firms are favored in corrupt auctions. Lastly, the paper explores policy implications. Analysis of the national anti-corruption campaign since 2012 suggests that general investigations may be insufficient to address deeply ingrained corrupt practices. Using counterfactuals based on an estimated structural model, the paper shows that implementing anonymous call-for-tender evaluations could improve social welfare by 10 percent by eliminating suspicious rules and encouraging broader participation.

Publication Reducing Carbon Dioxide Emissions through Joint Implementation of Projects(World Bank, Washington, DC, 2000-06)Efficient reduction of carbon dioxide emissions requires coordination of international efforts. Approaches proposed include carbon taxes, emission quotas, and jointly implemented energy projects. To reduce emissions efficiently, requires equalizing the marginal costs of reduction between countries. The apparently large differentials between the costs of reducing emissions in industrial and developing countries, implies a great potential for lowering the costs of reducing emissions by focusing on projects in developing countries. Most proposals for joint implementation of energy projects emphasize installing more technically efficient capital equipment, to allow reductions in energy use for any given mix of input, and output. But such increases in efficiency are likely to have potentially important second-round impacts: 1) Lowering the relative effective price of specific energy products. 2) Lowering the price of energy relative to other inputs. 3) Lowering the price of energy-intensive products relative to other products. The author explores the consequences of these second-round impacts, and suggests ways to deal with them in practical joint-implementation projects. For example, the direct impact of reducing the effective price of a fuel is to increase consumption of that fuel. Generally, substitution effects also reduce the use of other fuels, and the emissions generated from them. If the fuel whose efficiency is being improved, is already the least emission-intensive, the combined impact of these price changes is less likely to be favorable, and may even increase emissions. In the example the author uses, increase in coal use efficiency was completely ineffective in reducing emissions, because it resulted in emission-intensive coal being substituted for less polluting oil and gas.Publication Defining Results-Based Climate Finance, Voluntary Carbon Markets and Compliance Carbon Markets(Washington, DC, 2022)Under the Kyoto Protocol, compliance carbon markets (CCM) were primarily in the form of the Clean Development Mechanism (CDM) and Joint Implementation (JI). In 2015, the Paris Agreement introduced a new bottom-up approach to address climate change. Under the Paris Agreement, Parties set non-binding climate targets through their nationally determined contributions (NDCs). Article 6 of the Paris Agreement recognizes cooperation among countries for achieving their NDCs and raising climate ambition. This provides the basis for international CCM, where countries can trade emission reduction (“carbon”) credits with each other. Article 9 of the Paris Agreement stipulates that developed countries shall provide resources to developing countries for climate mitigation and adaptation. Developed countries would also take the lead in mobilizing climate finance from a variety of sources that represents a progression beyond previous efforts. The objective of this information paper is to outline three avenues for monetizing climate results – results-based climate finance (RBCF), voluntary carbon markets (VCM), and CCM. The paper is intended to describe activities by non-state or private sector actors in these mechanisms, and how their participation can facilitate the achievement of climate benefits in a cost-effective manner.Publication Assessment of Net Mitigation in the Context of International Greenhouse Gas Emissions Control Mechanisms(World Bank, Washington, DC, 2016-03)This paper discusses the scope for market mechanisms, already established for greenhouse gas mitigation in Annex 1 countries that ratified the Kyoto Protocol, for implementing "net mitigation," defined here as mitigation beyond Annex 1 countries' formal mitigation requirements under the Kyoto Protocol. Such market mechanisms could be useful for establishing and extending greenhouse gas mitigation targets also under the Paris Agreement from December 2015. Net mitigation is considered in two possible forms: as a "net atmospheric benefit," or as an “own contribution” by offset host countries. A main conclusion is that a “net atmospheric benefit” is possible at least in the short run, best implemented via stricter baselines against which offsets are credited; but it can also take the form of offset discounting whereby offset buyers are credited fewer credits. The latter, although generally inefficient, can be a second-best response to certain imperfections in the offset market, which are discussed in the paper. There is less merit for claiming that "own contributions" can lead to additional mitigation under existing mechanisms.Publication Results-Based Aid in the Energy Sector : An Analytical Guide(World Bank Group, Washington, DC, 2015-01)Results-based approaches (RBA) are becoming increasingly important, in both developed and developing countries. Within the energy sector, there are already several large-scale results-based schemes that make payments to implementers and service providers. However, support to national or regional governments based on the achievement of results in the energy sector remains unusual. This report seeks to explore the opportunity of utilizing RBA within the energy sector. It complements earlier work by vivid economics and the energy sector management assistance program (ESMAP) on results-based financing (RBF). The report constitutes one output in a broader research agenda on RBAs in the energy sector being undertaken by ESMAP of the World Bank. This report is intended to provide a high-level guide to results-based aid in the energy sector. It should be useful for a wide range of interested parties, including recipients, donor agencies, development practitioners, and academics. By providing a clear and justified analytical framework, the report ensures that the analysis is rigorous and open to critique. Chapter one gives introduction. Chapter two considers the theory of change underlying results-based aid, and uses this to derive four pre-conditions for RBA to be effective. Chapter three provides a discussion of the energy results chain, which can be used to frame the selection of results level and indicator. Chapter four outlines the factors to consider when selecting a results level and indicator for RBA. Chapter five considers when it is appropriate to target governments as the recipient in an aid program, rather than implementers or service providers. Chapter six discusses the remaining key design issues within an RBA agreement. A final section, chapter seven, considers the intersection between RBA and ongoing work on tracking and measuring energy access under the sustainable energy for all initiative.Publication Turning the Right Corner : Ensuring Development through a Low-Carbon Transport Sector(Washington, DC: World Bank, 2013-05-29)This report 'Turning the right corner - ensuring development through a low carbon transport sector' emphasizes that developing countries need to transition to a low carbon transport sector now to avoid locking themselves into an unsustainable and costly future. Furthermore, it argues that this transition can be affordable if countries combine policies to reduce greenhouse gas emissions with broader sector reforms aimed at reducing local air pollution, road safety risks, and congestion. This report looks at relationships between mobility, low carbon transport and development, drawing attention to the inertia in transport infrastructure. It complements the analysis by reviewing how climate change is likely to affect operations and infrastructure, cost-effective measures for minimizing negative effects, and policies and decision frameworks. It further highlights current and projected research findings and examples from developing countries. And it concludes that new technology is not enough, and that urgent action is needed before economies become locked into high-carbon growth. It discusses how to reconcile development with the need to curb emissions, looking at three sets of instruments and their limitations: new technologies and alternative fuels, supply-side measures, and demand-side policies. This report also looks at both available funding, such as carbon financing and international assistance, and at ways to generate new resources, considering that accounting for negative externalities dramatically alters the economics of transport investment.

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 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.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 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.
