Abstract
Georgia is upgrading its principal highway, running for more than 350 kilometers between the Black Sea on its western border and Azerbaijan in the east, at a cost of about 2.3 billion US dollars, or nearly 14 percent of its 2014 Gross domestic product (GDP). Apart from the immediate effects of the construction (financed largely by international institutions), how much will this relatively large investment improve economic conditions in Georgia? Will it significantly reduce travel costs, and if so, how much of the gain will flow through to the whole economy? Answers to those types of questions are rarely quantified for infrastructure projects in developing countries, either because the projects are too small or the necessary country-specific model is lacking. The Georgia project offered a unique combination of circumstances that made the estimations feasible: (1) a large investment relative to the size of the economy; (2) an already existing model and dataset depicting how the sectors of Georgia’s economy interact; and (3) partial completion of the road upgrade that allowed a simulation of expected gains to be informed by actual interim outcomes.

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 Private Participation in Transport : Lessons from Recent Experience in Europe and Central Asia(World Bank, Washington, DC, 2009-06)Facing fiscal constraints, many governments in Central and Eastern Europe and Southeastern Europe have pursued private finance for transport infrastructure more to move investments off budget than to improve efficiency and services. Results have been mixed and suggest a need to focus more on public-private partnerships (PPPs) that can achieve value for money. Today's economic environment will reduce the potential for PPP projects in the short term. Some PPP projects at an advanced stage of procurement may need additional public support, while ambitious projects may need to be phased to reduce their scale to what the market can absorb.Publication Transport at COP21(World Bank, Washington, DC, 2015-12)The case for climate action has never been stronger. Around the world, climate change is putting at risk the lives of millions of people as well as threatening many coastal cities and endangering trillion of dollars of investments in transport infrastructure and services. The Twenty-First Conference of the Parties (COP21) to the United Nations Framework Convention on Climate Change (UNFCCC) will bring heads of state and ministers to Paris at the end of November to reach a global climate agreement with far-reaching implications for low-carbon and climate-resilient growth. Transport is playing a greater role in COP21 than in past UNFCCC conferences as a critical part of the solution: a sector that can contribute to both reducing greenhouse gas (GHG) emissions and building economy wide resilience to the impacts of climate change. In view of the sector’s potential, the heavily debated transport question is how to sustainably meet the rising global demand for greater interconnectedness and mobility. The World Bank and the seven other leading multilateral development banks have joined forces with the Paris Process for Mobility and Climate (PPMC) and the rest of the transport community to call for more action on transport and climate change.Publication The Health Benefits of Transport Projects : A Review of the World Bank Transport Sector Lending Portfolio(Washington, DC : World Bank, 2008)This paper reviews the contribution of the World Bank's transport lending portfolio to health outcomes, as background for the Independent Evaluation Group's (IEG) evaluation of the Bank's support for health, nutrition and population (HNP). Over the past decade (FY97-06), the World Bank committed nearly $28 billion to 229 new transport projects managed by the Transport Sector Board (TSB). Specifically, the paper reviews the extent to which these projects: cite potential health benefits or risks in design documents; include specific objectives with respect to improving health outcomes or mitigating health risks; propose environmental improvements that are likely to provide health benefits; target transport services, and both health and behavioral outcomes to the poor; and plans to collect evidence on changes in health outcomes as a result of transport interventions. For completed projects, it assesses the extent to which expected health benefits or objectives have been achieved. This review of health benefits in the transport lending portfolio over the past decade shows that in the majority of the cases the focus has been on improvements in road safety, as measured by a reduction in the fatality or injury rates. Among the 55 projects with health related objectives, 82 percent had objectives to improve road safety, while only 7 percent had objectives to improve safety of other modes of transport and only 2 percent each had HIV/AIDS prevention or air quality improvement objectives.Publication Transport Activity Measurement Toolkit for On-Road Vehicles : Practitioners' Guide(World Bank, Washington, DC, 2011-06)Although urbanization is frequently cited as a major cause of greenhouse gas and local air pollution emissions growth, it could be better understood as one of the crucial links between climate and development. Urbanization is a major driver of development, and once in cities, people tend to increase their mobility dramatically, driving an increase in greenhouse gas and other emissions from transport. The demand for transport is not limited only to urban environments. As each economy becomes richer, its demand for passenger and freight mobility increases. This increase in car usage coupled with a tendency to have a lower number of passengers per car, has been sufficient to offset the improvements gained in vehicle fuel efficiency. The increasing transport demand, if not accompanied by adequate growth in infrastructure and facilities, leads to rising congestion, time loss, and air quality deterioration that can stifle economic growth and quality of life. Finding the delicate balance of policy options to achieve long-term improvements in on-road transport and reduce the impact of its externalities is critical and needs to be tailored to each locale. This requires measurements both to design the interventions and evaluate their impacts. This transport activity measurement toolkit (TAMT) has been developed specifically to simplify this measurement process by providing standardized software, data collection forms, and a consistent standardized methodology.

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 The Role of Social Ties in Factor Allocation(Published by Oxford University Press on behalf of the World Bank, 2019-10)We investigate whether social structure helps or hinders factor allocation using unusually rich data from the Gambia. Evidence indicates that land available for cultivation is allocated unequally across households; and that factor transfers are more common between neighbors, co-ethnics, and kinship-related households. Does this lead to the conclusion that land inequality is due to flows of land between households being impeded by social divisions? To answer this question, a novel methodology that approaches exhaustive data on dyadic flows from an aggregate point of view is introduced. Land transfers lead to a more equal distribution of land and to more comparable factor ratios across households in general. But equalizing transfers of land are not more likely within ethnic or kinship groups. In conclusion, ethnic and kinship divisions do not hinder land and labor transfers in a way that contributes to aggregate factor inequality. Labor transfers do not equilibrate factor ratios across households. But it cannot be ruled out that they serve a beneficial role, for example, to deal with unanticipated health shocks.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 MIGA Annual Report 2013 : Insuring Investments, Ensuring Opportunities(Washington, DC: World Bank Group, 2013-10-11)In fiscal year 2013, Multilateral Investment Guarantee Agency (MIGA) issued 2.8 billion dollars in investment guarantees for projects in our developing member countries. At 1.5 billion dollars, representing more than half of new business, the bulk of MIGA's guarantees issued support investments in Sub-Saharan Africa. Sixty-nine percent of new business volume this year was in complex projects in infrastructure and extractive industries, a strategic priority for the Agency. This year, 82 percent of MIGA's new volume fell into one or more of strategic priority areas: investments in the world's poorest countries, "South-South" investments, investments in conflict-affected countries, and investments in complex projects. MIGA also established the conflict-affected and fragile economies facility to further deepen support to this priority area.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.
