Abstract
This paper reviews the literature on the fiscal policy instruments commonly used to reduce transport sector externalities. The findings show that congestion charges would reduce vehicle traffic by 9 to 12 percent and significantly improve environmental quality. The vehicle tax literature suggests that every 1 percent increase in vehicle taxes would reduce vehicle miles by 0.22 to 0.45 percent and CO2 emissions by 0.19 percent. The fuel tax is the most common fiscal policy instrument; however its primary objective is to raise government revenues rather than to reduce emissions and traffic congestion. Although subsidizing public transportation is a common practice, reducing emissions has not been the primary objective of such subsidies. Nevertheless, it is shown that transport sector emissions would be higher in the absence of both public transportation subsidies and fuel taxation. Subsidies are also the main policy tool for the promotion of clean fuels and vehicles. Although some studies are very critical of biofuel subsidies, the literature is mostly supportive of clean vehicle subsidies.

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.

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 Pricing Externalities from Passenger Transportation in Mexico City(2009-10-01)The Mexico City Metropolitan Area has been suffering severely from transportation externalities such as accidents, air pollution, and traffic congestion. This study examines pricing instruments to reduce these externalities using an analytical and numerical model. The study shows that the optimal levels of a gasoline tax and a congestion toll on automobiles could generate social benefits, measured in terms of welfare gain, of US$132 and US$109 per capita, respectively, through the reduction of externalities. The largest component of the welfare gains comes from reduced congestion, followed by local air pollution reduction. The optimal toll and tax would, however, double the cost of driving and could be politically sensitive. Still, more than half of those welfare gains could be obtained through a more modest tax or toll, equivalent to $1 per gallon of gasoline. The welfare gains from reforming the pricing of public transportation are small relative to those from reforming the taxation of automobiles. Although the choice among travel modes depends on specific circumstances, in the absence of road travel pricing that accounts for externalities, there will be potential for higher investment in roads relative to mass transit. Given the rapidly increasing demand for transportation infrastructure in Mexico City, careful efforts should be made to include the full social costs of travel in evaluating alternative infrastructure investments.Publication Controlling Greenhouse Gas Emissions Generated by the Transport Sector in ECA : Policy Options(World Bank, Washington, DC, 2013-02)Greenhouse gas emissions (GHG) generated from transport are among the fastest growing in Europe and in the Europe and Central Asia (ECA) region, posing a challenge in creating a low-carbon future, as economic development has been paralleled with a modal share increasingly dominated by roads.1 This modal shift, as in the European Union (EU), has been driven by a number of factors, including growing affluence, suburbanization, and falling land use densities in urban areas, which have translated into more widespread vehicle ownership, increasing trip numbers and lengths, while reducing the financial viability of public transport and non-motorized transport. This paper begins by reviewing recent trends in transport and GHG emission trends in the ECA region, using trends in the EU-15 and EU-27 as comparators.8 Subsequently, it will provide an overview of climate friendly transport policies for the road, rail, and air transport modes, before presenting some land transport success stories and then turning to a discussion on how to use revenues generated from pricing policy instruments. The objective is to provide a menu of policy options to improve the functioning of the transport sector in ECA, while addressing the externalities generated by the sector.Publication Demand Side Instruments to Reduce Road Transportation Externalities in the Greater Cairo Metropolitan Area(World Bank, Washington, DC, 2012-06)Economically efficient prices for the passenger transportation system in the Greater Cairo Metropolitan Area would account for broader societal costs of traffic congestion and accidents, and local and global pollution. A $2.20 per gallon gasoline tax (2006 US$) would be economically efficient, compared with the current subsidy of $1.20 per gallon. Removal of the existing subsidy alone would achieve about three-quarters of the net benefits from subsidy elimination and the tax. Per-mile tolls could target congestion and accident externalities more efficiently than fuel taxes, although they are not practical at present. A combination of $0.80 per gallon gasoline tax to address pollution (versus $2.20 without tolls), and $0.12 and $0.19 tolls per vehicle mile on automobiles and microbuses, respectively, to address traffic congestion and accident externalities (versus $0.22 without fuel taxes) would be most efficient. Current public bus and rail subsidies are relatively close to efficient levels in the absence of such policies; however, if automobile and microbus externalities were fully addressed through more efficient pricing, optimal subsides to public transit would be smaller than current levels.Publication Estimating the Size of External Effects of Energy Subsidies in Transport and Agriculture(World Bank Group, Washington, DC, 2015-04)It is widely accepted that the costs of underpricing energy are large, whether in advanced or developing countries. This paper explores how large these costs can be by focussing on the size of the external effects that energy subsidies in particular generate in two important sectors—transport and agriculture—in two countries in the Middle East and North Africa, the Arab Republic of Egypt (transport) and the Republic of Yemen (agriculture). The focus is mainly on the costs associated with congestion and pollution, as well as the impact of underpriced energy for depletion of scarce water resources, including through crop selection. Quantifying the size of external effects in developing countries has received relatively little analytical attention, although there is a significant body of literature for developed countries. By building on earlier research, as well as employing the United Nations ForFITS model, the paper provides indicative estimates of the external costs of energy subsidies, as manifested in congestion and pollution. The estimates using simulations indicate that these costs could be materially reduced by elimination or reduction of energy subsidies. The paper also describes the impact of energy subsidies on water consumption in a region where water resources are particularly limited. The findings provide further evidence of the adverse and significant consequences of subsidizing energy.Publication Why Have CO2 Emissions Increased in the Transport Sector in Asia? Underlying Factors and Policy Options(2009-10-01)Rapidly increasing emissions of carbon dioxide from the transport sector, particularly in urban areas, is a major challenge to sustainable development in developing countries. This study analyzes the factors responsible for transport sector CO2 emissions growth in selected developing Asian countries during 1980-2005. The analysis splits the annual emissions growth into components representing economic development; population growth; shifts in transportation modes; and changes in fuel mix, emission coefficients, and transportation energy intensity. The study also reviews existing government policies to limit CO2 emissions growth, particularly various fiscal and regulatory policy instruments. The study finds that of the six factors considered, three - economic development, population growth, and transportation energy intensity - are responsible for driving up transport sector CO2 emissions in Bangladesh, the Philippines, and Vietnam. In contrast, only economic development and population growth are responsible in the case of China, India, Indonesia, Republic of Korea, Malaysia, Pakistan, Sri Lanka, and Thailand. CO2 emissions exhibit a downward trend in Mongolia due to decreasing transportation energy intensity. The study also finds that some existing policy instruments help reduce transport sector CO2 emissions, although they were not necessarily targeted for this purpose when introduced.

Publication Classroom Assessment to Support Foundational Literacy(Washington, DC: World Bank, 2025-03-21)This document focuses primarily on how classroom assessment activities can measure students’ literacy skills as they progress along a learning trajectory towards reading fluently and with comprehension by the end of primary school grades. The document addresses considerations regarding the design and implementation of early grade reading classroom assessment, provides examples of assessment activities from a variety of countries and contexts, and discusses the importance of incorporating classroom assessment practices into teacher training and professional development opportunities for teachers. The structure of the document is as follows. The first section presents definitions and addresses basic questions on classroom assessment. Section 2 covers the intersection between assessment and early grade reading by discussing how learning assessment can measure early grade reading skills following the reading learning trajectory. Section 3 compares some of the most common early grade literacy assessment tools with respect to the early grade reading skills and developmental phases. Section 4 of the document addresses teacher training considerations in developing, scoring, and using early grade reading assessment. Additional issues in assessing reading skills in the classroom and using assessment results to improve teaching and learning are reviewed in section 5. Throughout the document, country cases are presented to demonstrate how assessment activities can be implemented in the classroom in different contexts.Publication 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 Argentina Country Climate and Development Report(World Bank, Washington, DC, 2022-11)The Argentina Country Climate and Development Report (CCDR) explores opportunities and identifies trade-offs for aligning Argentina’s growth and poverty reduction policies with its commitments on, and its ability to withstand, climate change. It assesses how the country can: reduce its vulnerability to climate shocks through targeted public and private investments and adequation of social protection. The report also shows how Argentina can seize the benefits of a global decarbonization path to sustain a more robust economic growth through further development of Argentina’s potential for renewable energy, energy efficiency actions, the lithium value chain, as well as climate-smart agriculture (and land use) options. Given Argentina’s context, this CCDR focuses on win-win policies and investments, which have large co-benefits or can contribute to raising the country’s growth while helping to adapt the economy, also considering how human capital actions can accompany a just transition.Publication Europe and Central Asia Economic Update, Spring 2025: Accelerating Growth through Entrepreneurship, Technology Adoption, and Innovation(Washington, DC: World Bank, 2025-04-23)Business dynamism and economic growth in Europe and Central Asia have weakened since the late 2000s, with productivity growth driven largely by resource reallocation between firms and sectors rather than innovation. To move up the value chain, countries need to facilitate technology adoption, stronger domestic competition, and firm-level innovation to build a more dynamic private sector. Governments should move beyond broad support for small- and medium-sized enterprises and focus on enabling the most productive firms to expand and compete globally. Strengthening competition policies, reducing the presence of state-owned enterprises, and ensuring fair market access are crucial. Limited availability of long-term financing and risk capital hinders firm growth and innovation. Economic disruptions are a shock in the short term, but they provide an opportunity for implementing enterprise and structural reforms, all of which are essential for creating better-paying jobs and helping countries in the region to achieve high-income status.Publication Morocco Economic Update, Winter 2025(Washington, DC: World Bank, 2025-04-03)Despite the drought causing a modest deceleration of overall GDP growth to 3.2 percent, the Moroccan economy has exhibited some encouraging trends in 2024. Non-agricultural growth has accelerated to an estimated 3.8 percent, driven by a revitalized industrial sector and a rebound in gross capital formation. Inflation has dropped below 1 percent, allowing Bank al-Maghrib to begin easing its monetary policy. While rural labor markets remain depressed, the economy has added close to 162,000 jobs in urban areas. Morocco’s external position remains strong overall, with a moderate current account deficit largely financed by growing foreign direct investment inflows, underpinned by solid investor confidence indicators. Despite significant spending pressures, the debt-to-GDP ratio is slowly declining.
