We investigate the conditions for sustainability of debt roll-over schemes under uncertainty. In contrast with the requirements identified in recent research, we show that a necessary and sufficient condition for sustainability of such schemes is that the asymptotic interest rate on government debt be lower than the asymptotic growth rate of the economy, a natural extension of a familiar criterion in a deterministic framework. However, we also show that for realistic parameter values, Ponzi games that are sustainable in the long run may display explosive patterns over relatively long horizons. This may explain why governments may be reluctant to play Ponzi games even when they are feasible in the long run.

This paper presents a practical guide to public debt dynamics, fiscal sustainability, and cyclical adjustment of budgetary aggregates. The paper discusses fiscal formulas, which may be of practical use in fiscal analysis. The paper derives, respectively, the formulas for debt dynamics, and cyclical and inflation adjustment of budgetary aggregates. It discusses other relationships for special applications, and some practical implications and usage. The formulas related to debt dynamics are based on the assumption that changes in liabilities are the result of above-the-line budgetary operations.
Topics discussed in this publication include: an introduction to theoretical and practical aspects of fiscal sustainability; theoretical prerequisites for fiscal sustainability analysis; debt indicators in the measurement of vulnerability; cyclical adjustment of budget surplus; pro-cyclical fiscal policy using Mexico's fiscal accounts as a case study; fiscal rules and the experience of Chile; currency crises and models for deal with financing costs.
This paper focuses on exchange rate economics. Two main views of exchange rate determination have evolved since the early 1970s: the monetary approach to the exchange rate (in flexible-price, sticky-price, and real interest differential formulations); and the portfolio balance approach. In this paper, the literature on these views is surveyed, followed by a discussion of the empirical evidence and likely future developments in the area of exchange rate determination. The literature on foreign exchange market efficiency, exchange rates and “news,” and international parity conditions is also reviewed.
"The Sovereign Debt Crisis," 2012 edition, looked at how governments ran up substantial deficits in order to avert a worldwide depression and their subsequent attempts to rebalance their budgets. This updated edition concentrates on the delicate balancing act the economies of the United States, Japan, and the eurozone face between the present need to boost sluggish economic growth by providing sufficiently cheap, low-risk credit and the longer-term challenges of cutting massive debt and returning to a sustainable fiscal policy. The authors argue that many of the euro area economies, having noticeable difficulty paying their international debts, are in a sovereign debt crisis, while America and Japan are, for now, holding steady but in real danger of slipping into crisis. The book shows how the process has evolved in these three major developed economies and how their policy choices impact global financial markets.
Market Behaviour and Macroeconomic Modelling discusses several state-of-the-art developments in the modelling approach to market behaviour in macroeconomic modelling. Leading experts in this field, deal with the implications of market imperfections in commodity markets, capital markets and labour markets for macroeconomic modelling and stabilization policy. They demonstrate that incorporating market imperfections leads to very different policy recommendations than those derived from the standard perfect competition model.
Addressing the global financial crisis has required fiscal intervention on a substantial scale by governments around the world. The consequent buildup of public debt, in particular its sustainability, has moved to center stage in the policy debate. If the Asia and Pacific region is to continue to serve as an engine for global growth, its public debt must be sustainable. Public Debt Sustainability in Developing Asia addresses this issue for Asia and the Pacific as a whole as well as for three of the most dynamic economies in the region: the People’s Republic of China, India, and Viet Nam. The book begins with a discussion of the reasons for increased attention to debt-related issues. It also introduces fiscal indicators for the Asian Development. Bank’s developing member countries and economies. The sustainability of their debt is assessed through extant approaches and with the most up-to-date data sources. The book also surveys the existing literature on debt sustainability, outlining the main issues related to it, and discusses the key implications for the application of debt sustainability analysis in developing Asia. Also highlighted is the importance of conducting individual country studies in view of wide variations in definitions of public expenditure, revenues, contingent liabilities, government structures (e.g., federal), and the like, as well as the impact of debt on interest rates. The book further provides in-depth debt sustainability analyses for the People’s Republic of China, India, and Viet Nam. Public Debt Sustainability in Developing Asia offers a comprehensive analytical and empirical update on the sustainability of public debt in the region. It breaks new ground in examining characteristics that are crucial to understanding sustainability and offers richer policy analysis that should prove useful for policymakers, researchers, and graduate students.
The sharp increase in fiscal deficits and public debt in most advanced and several developing economies has raised concerns about the sustainability of public finances and highlighted the need for a significant adjustment over the medium term. This paper assesses the usefulness of fiscal rules in supporting fiscal consolidation, discusses the design and implementation of rules based on a new data base spanning the whole Fund membership, and explores the fiscal framework that could be adopted as countries emerge from the crisis.
"Fiscal policy makers have faced an extraordinarily challenging environment over the last few years. At the outset of the global financial crisis, the International Monetary Fund (IMF) for the first time advocated a fiscal expansion across all countries able to afford it, a seeming departure from the long-held consensus among economists that monetary policy rather than fiscal policy was the appropriate response to fluctuations in economic activity. Since then, the IMF has emphasized that the speed of fiscal adjustment should be determined by the specific circumstances in each country. Its recommendation that deficit reduction proceed steadily, but gradually, positions the IMF between the fiscal doves (who argue for postponing fiscal adjustment altogether) and the fiscal hawks (who argue for a front-loaded adjustment). This volume brings together the analysis underpinning the IMF's position on the evolving role of fiscal policy. After establishing its analytical foundation, with chapters on such topics as fiscal risk and debt dynamics, the book analyzes the buildup of fiscal vulnerabilities before the crisis, presents the policy response during the crisis, discusses the fiscal outlook and policy challenges ahead, and offers lessons learned from the crisis and its aftermath. Topics discussed include a historical view of debt accumulation; the timing, size, and composition of fiscal stimulus packages in advanced and emerging economies; the heated debate surrounding the size of fiscal multipliers and the effectiveness of fiscal policy as a countercyclical tool; coordination of fiscal and monetary policies; the sovereign debt crisis in Europe; and institutional reform aimed at fostering fiscal discipline."--Publisher's description.
