This paper provides new evidence of the macroeconomic effects of public investment in advanced economies. Using public investment forecast errors to identify the causal effect of government investment in a sample of 17 OECD economies since 1985 and model simulations, the paper finds that increased public investment raises output, both in the short term and in the long term, crowds in private investment, and reduces unemployment. Several factors shape the macroeconomic effects of public investment. When there is economic slack and monetary accommodation, demand effects are stronger, and the public-debt-to-GDP ratio may actually decline. Public investment is also more effective in boosting output in countries with higher public investment efficiency and when it is financed by issuing debt.

This book analyzes the dynamic macroeconomic effects of public capital in industrialized countries. The issue of whether public capital is productive has received a great deal of recent attention. Yet, existing empirical analyses have been limited to a small set of countries. This book presents a new database that provides internationally comparable capital stock estimates for 22 OECD countries for the 1960-2001 period. Building on this database, the book estimates the dynamic effects of public capital using a variety of econometric methods. The results suggest that public capital is productive in OECD countries on average. The theoretical analysis based on a dynamic general equilibrium model shows that the effects of public capital depend crucially on the way the government chooses to finance additional spending.

This paper provides new empirical evidence of the macroeconomic effects of public investment in developing economies. Using public investment forecast errors to identify unanticipated changes in public investment, the paper finds that increased public investment raises output in the short and medium term, with an average short-term fiscal multiplier of about 0.2. We find some evidence that the effects are larger: (i) during periods of slack; (ii) in economies operating with fixed exchange rate regimes; (iii) in more closed economies; (iv) in countries with lower public debt; and (v) in countries with higher investment efficiency. Finally, we show that increases in public investment tend to lower income inequality.

To investigate the effects on Papua New Guinea’s economy of substantial liquified natural gas revenues arriving in 2015, we employ a model to examine the macroeconomic effects of a scalingup of natural resource windfall revenues and the implications for a variety of policy responses. The model is a multi-sector dynamic stochastic general equilibrium (DSGE) model, and features components that allow for a detailed study of the effects of both fiscal and monetary policy in response to a positive shock to the mineral resource value of a country. The model contains tradable, non-tradable, and mining sectors, as well as an independent central bank and fiscal authority. We calibrate the model to the current economy of Papua New Guinea and run a suite of policy simulations. We find that macroeconomic effects from a resource boom typically associated with Dutch Disease effects such as a real appreciation and a fall in tradable sector production stem largely from the non-tradable component of government spending. The central bank can offset the real appreciation, but not without crowding out the private sector. A sovereign wealth fund (SWF), combined with a smooth capital spending path, entails the best means of dealing with macroeconomic volatility and maintaining a stable fiscal regime.

This textbook equips instructors and students with an overview of the existing literature so that the latter can attain an overall understanding of macroeconomic and microeconomic public finance. The literature on public finance has grown dramatically with theoretical studies and empirical analysis, and much of the focus has been on macroeconomic effects of public services. The standard textbook offerings, however, are mainly restricted to microeconomic topics of public finance. This text intends to fill this gap by presenting a theoretical-based, comprehensive explanation of public finance. Particular emphasis is directed at developing tools that can be applied theoretically and empirically to clarify essential economic concerns in the current public sector in advanced countries, including Japan. Such concerns include the macroeconomic effect of fiscal policy, the dependence on bonds for covering government deficits, and social security reform. The main text explains the standard concepts of public finance, and the appendix offers various advanced topics. The material will facilitate an understanding of how to investigate changes in the public sector, interpret results, and basically do research on fiscal policy. The textbook will be of value to a broad range of course offerings, including those generally focused on fiscal policy, on social security reform and on tax reform.

The pace of recovery has disappointed in recent years, and downside risks have increased, including from heightened geopolitical tensions. These increased risks make it a priority to raise actual and potential growth. In a number of economies, an increase in public infrastructure investment can also provide support to demand and help boost potential output. And in advanced economies as well as emerging and developing economies there is a general, urgent need for structural reforms to strengthen growth potential or make growth more sustainable. The four individual chapters examine the overall global outlook, the prospects for individual countries and regions, the benefits of increased public infrastructure investment in terms of raising output, and the extent to which global imbalances have narrowed significantly since their peak in 2006.

We estimate the short-term effects of fiscal consolidation on economic activity in 14 countries in Latin America and the Caribbean. We examine contemporaneous policy documents to identify changes in fiscal policy motivated by a desire to reduce the budget deficit and not by responding to prospective economic conditions. Based on this narrative dataset, our estimates suggest that fiscal consolidation has contractionary effects on GDP, consistent with a multiplier of 0.9. We find these effects to be close to those in OECD countries based on a similarly constructed dataset (Devries and others, 2011). We also find similar estimation results for the two groups of economies for the effect of fiscal consolidation on the external current account balance, providing support for the twin deficits hypothesis.

This paper analyzes the tradeoffs between savings, debt and public investment in the Republic of Congo, a developing country with looming oil exhaustibility concerns. Our results highlight the risks to fiscal and capital sustainability of oil exporting countries from large scaling-up in public investment and oil price volatility in view of a projected decline in the oil revenue to GDP ratio. However, structural reforms that improve the efficiency of public investment can allow for a relatively faster buildup of sustainable public capital and sustain higher non-oil growth without adversely affecting the debt ratio or savings. Moreover, we show that even if a government pursues prudent fiscal policy that preserves resource wealth and debt sustainability in the face of exhaustible and volatile resource revenues, low public investment quality in the form of a misallocation of resources can hinder attainment of sustainable public capital and positive non-oil growth.

Physical Capital Development and Energy Transition in Latin America and the Caribbean introduces the reader to applied theory and potential solutions to manage the transition from fossil energies to renewables given the resource wealth and infrastructural limitations of Latin American and Caribbean (LAC) countries. The work presents consistent empirical approaches and relevant econometric approaches grounded in case studies that offer realistic portrayals of complex multidisciplinary phenomena. It provides policymakers with the knowledge needed for economic decision-making, especially regarding the energy transition and the physical capital development in the LAC (and similar developing regions). The work concludes by road mapping future LAC physical capital investment options to promote 21st-century sustainable energy development. - Analyses the macroeconomics of physical capital and energy transition in LAC countries - Uses case studies to draw pragmatic comparative energy policy implications - Deploys econometric techniques to address empirical approaches on energy and development economics - Discusses the effects of the energy transition on environmental degradation - Links energy economics and public investment management

How effective was public investment in stimulating the Japanese economy during the economic stagnation of the 1990s? Using a dataset of regional public investment spending, we find that investment multipliers were higher than for public consumption, although they were relatively low and declining over time. The paper also finds that the effectiveness of economic infrastructure investment, implemented mainly by the central government, is lower than that of social investment mostly undertaken by local governments. These results suggest that while public investment may yield higher output effects than other spending, its effectiveness depends upon its composition, the level of government implementation, and supply side factors.
