While expanding public investment can help filling infrastructure bottlenecks, scaling up too much and too fast often leads to inefficient outcomes. This paper rationalizes this outcome looking at the association between cost inflation and public investment in a large sample of road construction projects in developing countries. Consistent with the presence of absorptive capacity constraints, our results show a non-linear U-shaped relationship between public investment and project costs. Unit costs increase once public investment is close to 10% of GDP. This threshold is lower (about 7% of GDP) in countries with low investment efficiency and, in general, the effect of investment scaling up on costs is especially strong during investment booms.
This paper investigates how macroeconomic uncertainty affects the fiscal multiplier of public investment. In theory, uncertainty can reduce the multiplier if the private sector becomes more cautious and does not respond to the fiscal stimulus. Conversely, it can increase the fiscal multiplier if public investment shocks improve private agents’ expectations about future economic outlook, and lead to larger private spending. Using the disagreement about GDP forecasts as a proxy for uncertainty, we find that unexpected increases in public investment have larger and longer-lasting effects on output, investment, and employment during periods of high uncertainty, with multipliers above 2, and the larger multipliers are not driven by economic slack. Public investment shocks are also found to boost private sector confidence during heightened uncertainty, driving-up expectations about future economic development which in turn magnify private sector response to the initial stimulus.
A structural growth slowdown is under way across the world: at current trends, the global rate of potential growth is expected to fall to a three-decade low over the remainder of the 2020s. Nearly all the forces that have powered growth and prosperity since the early 1990s have weakened. In addition, a series of shocks has affected the global economy over the past three years. A persistent and broad-based decline in long-term growth prospects imperils the ability of emerging market and developing economies to combat poverty, tackle climate change, and meet other key development objectives. The challenges presented by this potential inability call for an ambitious policy response at the national and global levels. This book presents the first detailed analysis of the growth slowdown and a rich menu of policy options to deliver better growth outcomes. ------------------------------------------------------------------------------------------------------------- This book presents a sobering analysis of the secular growth slowdown based on the most comprehensive database of potential growth estimates available to date. With nearly all the forces that have driven growth and prosperity in recent decades now weakened, the book argues that a prolonged period of weakness is under way, with serious implications for emerging market and developing economies. The authors call for bold policy actions at both the national and global levels to lift growth prospects. The book is essential reading for policy makers, economists, and anyone concerned about the future of the global economy. Beatrice Weder di Mauro Professor of International Economics, Geneva Graduate Institute, and President of the Centre for Economic Policy Research (CEPR) Economic policy making is becoming increasingly complicated in the 2020s. In addition to tackling traditional trade-offs in aggregate demand management and improving efficiency on the supply side, policy makers need to address new priorities and challenges, from addressing climate change and its impacts to improving income distribution, all in the context of lower growth rates, waning productivity growth, and flattening of the globalization process that has brought unprecedented prosperity across the globe and lifted more than a billion people out of poverty. In Falling Long-Term Growth Prospects, the authors do a phenomenal job of assessing these trends at the global and regional levels, identifying and unpacking salient twenty-first-century policy challenges, and providing thoughtful and evidence-based policy prescriptions for leaders in advanced, emerging market, and developing economies. Importantly, the book underscores that these challenges tend to be global and, hence, global cooperation at all levels is necessary to achieve optimal results. Alas, we seem to be going in the opposite direction; this book offers a road map to put us back on the path to creating a more integrated, prosperous, and equitable global community. Michael G.

Investment in infrastructure can be a driving force of the economic recovery in the aftermath of the COVID-19 pandemic in the context of shrinking fiscal space. Public-private partnerships (PPP) bring a promise of efficiency when carefully designed and managed, to avoid creating unnecessary fiscal risks. But fiscal illusions prevent an understanding the sources of fiscal risks, which arise in all infrastructure projects, and that in PPPs present specific characteristics that need to be addressed. PPP contracts are also affected by implicit fiscal risks when they are poorly designed, particularly when a government signs a PPP contract for a project with no financial sustainability. This paper reviews the advantages and inconveniences of PPPs, discusses the fiscal illusions affecting them, identifies a diversity of fiscal risks, and presents the essentials of PPP fiscal risk management.
International cooperation has never been more needed, but the current system of "aid" is outdated and ineffective. The Future of Aid calls for a wholesale restructuring of the aid project, a totally new approach fit for the challenges of the 21st century: Global Public Investment. Across the world, billions of people are struggling to get by in unequal and unsustainable societies, and international public finance, which should be part of the answer, is woefully deficient. Engagingly written by a well-known expert in the field, The Future of Aid calls for a series of paradigm shifts. From a narrow focus on poverty to a broader attack on inequality and sustainability. From seeing international public money as a temporary last resort, to valuing it as a permanent force for good. From North-South transfers to a collective effort, with all paying in and all benefitting. From outdated post-colonial institutions to representative decision-making. From the othering and patronising language of "foreign aid", to the empowering concept of Global Public Investment. Ten years ago, in The Trouble with Aid, Jonathan Glennie highlighted the dangers of aid dependency and the importance of looking beyond aid. Now he calls for a revolution in the way that we think about the role of public money to back up our ambitious global objectives. In the wake of the COVID-19 crisis, it is time for a new era of internationalism.
The result of two years work by 19 experienced policymakers and two Nobel prize-winning economists, 'The Growth Report' is the most complete analysis to date of the ingredients which, if used in the right country-specific recipe, can deliver growth and help lift populations out of poverty.
The Public Investment Management (PIM) Reference Guide aims to convey country experiences and good international practices as a basis for decisions on how to address a country-specific PIM reform agenda. The country references are drawn largely from previous diagnostics and technical assistance reports of the World Bank. The application of country diagnostics and assessments has revealed a need to address the following issues when undertaking a country reform in PIM: • Clarification of the definition and scope of public investment and public investment management • Establishment of a sound legal, regulatory, and institutional setting for PIM, making sure it is linked to the budget process • Allocation of roles and responsibilities for key players in PIM across government • Strengthening of guidance on project preappraisal, appraisal, and selection-prioritization procedures and deepening of project appraisal methodologies • Integration of strategic planning, project appraisal-selection, and capital budgeting • Management of multiyear capital budget allocations and commitments • Efforts to address effective implementation, procurement, and monitoring of projects • Strengthening of asset management and ex post evaluation • Integration of PIM and public-private partnership (PPP) in a unified framework • Rationalization and prioritization of the existing PIM project portfolio • Development of a PIM database and information technology in the form of a PIM information system. The PIM Reference Guide does not seek to provide definitive answers or standard guidance for the common PIM issues facing countries. Nor does it seek to provide a detailed template for replication across countries: this would be impossible given the diversity of country situations. Instead, each chapter begins with an overview of the specific reform issue, lists approaches and experiences from different countries, and summarizes the references and good practices to be considered in designing country-specific reform actions.
Setting macroeconomic policy is especially difficult in fragile states. Macroeconomic Policy in Fragile States addresses the many issues involved and considers ways to improve the effectiveness of macroeconomic management in the face of these constraints.

Asia has shown the world what success in economic development looks like. From the amazing transformations of Japan, the Republic of Korea, and the other ‘tigers’ in the early 70s, to the more recent takeoffs of the People’s Republic of China (PRC), India, and the leading economies in Southeast Asia, the region has prospered at a startling pace. Technologies were adopted, productivity raised, and export markets conquered. Billions were lifted out of poverty. What was once a backwater is now a global engine of growth.
The book considers when governments should give guarantees to private investors. After describing the history of guarantees, and the challenges the politics and psychology create for good decisions, the book sets out a principles for allocating risk (and therefore guarantees), techniques for valuing guarantees, and rules to encourage good decisions.
