Public debt seems to be one of the great issues of the nineties. The United States have turned from the largest creditor of the world to the largest debtor, due to dramatic budget deficits. The European Union tries to build dams against the flood, see the treaty of Maastricht. And in Germany, public debt tends to explo de, doubling within a few years. The reason for this is the immense cost of Ger man unification. I had many helpful talks with my colleague Michael Schmid (now at Bam berg). In addition, Michael Brauninger and Philipp Lichtenauer carefully discus sed with me all parts of the manuscript. Last but not least, Doris Ehrich typed the manuscript as excellently as ever. I would like to thank all of them. Contents INTRODUCTION 3 5 BRIEF SURVEY OF THE LITERATURE PART I. CLOSED ECONOMY 9 CHAPTER I. SOLOW MODEL 11 1. Fixed Deficit Ratio 11 1. 1. Simple Model 11 1. 2.

This book studies the sustainability and optimality of public debt under different scenarios: the closed economy, the small open economy, and a two-country setting. Sustainability refers to the existence and the stability of the long-run equilibrium. Optimality relates to the path of public debt that maximizes discounted utility. The analysis is conducted within the framework of the Solow model, the overlapping generations model and the infinite horizon model. The government can follow different strategies, it either fixes the deficit ratio or the tax rate. As a result, a fixed deficit ratio generally can be sustained. By contrast, a fixed tax rate generally cannot be sustained. Depending on the chosen fiscal strategy, there exists either an optimal deficit ratio or an optimal tax rate that maximizes the sum of consumption and government purchases per capita.

This study presents the facts, arguments and scenarios around public debt from a global perspective. Especially the largest economies feature record debt and fiscal risks, including from population ageing and financial imbalances. Given low interest rates, there is no imminent problem. But at some point, debt will have to come down. There are four possible scenarios how debt could come down. First, governments could economise and reform. Second, governments could default. Third, governments could erode the real value of debt via inflation and negative real interest rates. However, this scenario cannot continue forever. Policy errors can prompt a loss of confidence, destabilisation and crisis. This fourth scenario last included the largest economies in the 1970s. It would become a major global challenge if it were to happen again in today's interconnected world.

The initial government debt-to-GDP ratio and the government’s commitment play a pivotal role in determining the welfare-optimal speed of fiscal consolidation in the management of a debt crisis. Under commitment, for low or moderate initial government debt-to-GPD ratios, the optimal consolidation is very slow. A faster pace is optimal when the economy starts from a high level of public debt implying high sovereign risk premia, unless these are suppressed via a bailout by official creditors. Under discretion, the cost of not being able to commit is reflected into a quick consolidation of government debt. Simple monetary-fiscal rules with passive fiscal policy, designed for an environment with “normal shocks”, perform reasonably well in mimicking the Ramsey-optimal response to one-off government debt shocks. When the government can issue also long-term bonds–under commitment–the optimal debt consolidation pace is slower than in the case of short-term bonds only, and entails an increase in the ratio between long and short-term bonds.

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.

This paper presents a model of optimal taxation in which both private agents and the government can default on their debt. We first consider Ramsey equilibria in which the government can precommit to its policies but in which private agents can default. We then consider sustainable equilibria in which both government and private agent decision rules are required to be sequentially rational. We show that when there is sufficiently little discounting and government consumption fluctuates enough, the Ramsey allocations and policies (in which the government never defaults) can be supported by a sustainable equilibrium.

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.

This paper proposes a signaling model that offers a new perspective on why governments deviate from optimal tax smoothing and delay debt stabilization. In our model, dependable—but not fully credible—governments have an incentive to tighten the fiscal regime when the signaling effect on credit ratings is larger (that is, when a sufficiently large stock of debt has been accumulated). At this point, they may deviate from tax smoothing not to be mimicked by weak governments. The model predicts that primary balances and debt stocks are complementary inputs in the credit rating function as tests on Italian, Irish, Belgian, and Danish data show.
