Public Debt Sustainability

As countries recover from the coronavirus pandemic, they are confronted with an even more challenging debt crisis. Xavier Debrun argues in the foreword that in deciding where we go from here that there is no longer a consensus regarding the optimum design and enforcement of fiscal rules. Rather we must address a series of questions and challenges to the conventional wisdom. This book provides an opportunity for scholars to explore these questions from an international perspective, with reference to European countries, and emerging nations as well as the United States.

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.

Despite its beneficial aspects, public debt can be hazardous for macroeconomic performance should it reach unrepayable levels as a consequence of snowballing explosive trends. Failure to monitor the existing trend in public debt in order to detect such divergences from the stable path, and the lack of an adaptive public financial management can potentially culminate in a public debt crisis whose disruptive economic impacts can permeate all sectors of the economy very swiftly. However, public debt sustainability is a vague concept with no straightforward operational definitions. In addition, its multi-faceted nature is an impediment for the implementation of real-world appraisal of the fiscal posture from a stability viewpoint. As such, quantifying the public debt sustainability is essential for overhauling the fiscal policies so as to avoid a potential debt crisis stemming from malfunctioning fiscal policies. This book provides the reader with a practical and straightforward framework that outlines a tool for undertaking public debt sustainability analysis. In order to guide further empirical investigations, the discussion in this book is underpinned by a real-world application of the model which highlights the practical aspects of the tool with reference to time-varying empirical evidence from a developing country.

Public debt has become a severe problem for a great many economies. While the effects of tax policies on the allocation of resources are readily derived, the mechanisms that make public deficits and debt influence the economy are not so easily understood. This book elaborates on the effects of public debt starting from the intertemporal budget constraint of the government. It is shown under which conditions a government can stick to the intertemporal budget constraint and then, demonstrated how public debt affects the growth process and welfare in market economies. The effects are derived for models with complete labor markets as well as taking into account labor market imperfections. The focus in this book is on fiscal policy issues, but it also deals with monetary policy aspects. The theoretical analysis is complemented with empirical time series analyses on debt sustainability and with panel studies dealing with the relationship between public debt and economic growth.

The paper offers an approach to assessing the sustainability of public debt taking into account the effect of fiscal policy on output, as well as uncertainty in the model parameters and system dynamics. Uncertainty is specified in general terms, and the analysis is based on the notion of invariant sets. Examples are provided to illustrate how the method can be applied in practice.

The book begins with a discussion of the reasons why there is increased attention on debt related issues and outline the contents of the volume. The book also includes fiscal indicators for Developing Member Countries (DMCs) as categorized by the Asian Development Bank (ADB). Debt sustainability for these countries is assessed through extant approaches and with the most updated data sources. It also surveys the extant literature on debt sustainability, outlining the main issues related to debt sustainability and discusses the key implications for the application of debt sustainability analysis in developing Asia. The book highlights the importance of doing 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 in the impact of debt on interest rates. It provides in-depth debt sustainability analyses of China, India and Vietnam. The book is a comprehensive analytical and empirical update of the sustainability public debt in developing Asia. It breakes new ground in that various characteristics of the sustainability that have not yet been explored in the literature which, nevertheless, are crucial to understanding it. As a consequence, the policy analysis is based on firmer footings than in the extant literature and should prove useful to graduate students, researchers as well as policymakers.

This paper proposes a framework for public debt sustainability analysis (DSA) that is complementary to that generally used by IFIs. The DSA in this paper has three components: (i) an integrated and consistent accounting framework for the Consolidated Public Sector (CPS); (ii) the estimation of an appropriate, and country-specific debt threshold, following the approach proposed by Reinhart, Rogoff and Savastano (2003); and (iii) a method for the calculation of the CPS primary balance to achieve the desired debt targets, without resorting to ad-hoc assumptions for the values of the macroeconomic variables during the planning horizon, in the spirit of Garcia and Rigobon (2004) and Celasun, Debrun and Ostry (2006). The paper uses this approach to analyze the sustainability of the Dominican Republic's Public Debt.
