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 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.

Under what circumstances can market forces prevent unsustainable borrowing? Effective market discipline requires that capital markets be open, that; information on the borrower’s existing liabilities be readily available, that no bailout be anticipated, and that the borrower respond to market signals. This paper explores the implications of these conditions, and reviews some relevant empirical evidence.

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.

This book is an attempt to build some structure around the issues of sovereign debt to help guide economists, practitioners, and policymakers through this complicated, but not intractable, subject.

Examining various methods of debt management used in the US., Handbook of Debt Management, provides a comprehensive analysis of securities offered for sale by municipalities, states, and the federal government. The book covers laws regarding municipal bonds, the economic choice between debt and taxes and the tax-exempt status of municipal bond owners, capital budgeting, including state and local government practices, developing governmental and intergovernmental debt policies, pay-as-you-go with debt financing for capital projects, US Internal Revenue Service regulations on arbitrage in state and local government debt proceeds investment, US treasury auctions, and more.

This book examines the challenges facing the international monetary and financial system, as well as the future role of the Bretton Woods institutions in addressing those challenges. The volume is based on the proceedings of a 2004 conference cosponsored by the Banco de Espana and the International Monetary Fund to commemorate the 60th anniversary of the Bretton Woods meetings in July 1944. The chapters look at global imbalances, exchange rate issues, debt in emerging economies, and innovations in private and multilateral lending.

This book presents a theoretically-based comprehensive analysis of macroeconomic consequences of fiscal policy using a popular economic model: the overlapping generations growth model. A wide range of essential public finance issues is analyzed, including the effects of tax reform on dynamic efficiency, positive and normative effects of public spending, considerations of taxes on fixed assets and monetary holdings, and sustainability of deficits. A unique approach is applied in the study of public finance: one expected to generate substantial interest among current graduate students and active researchers.
