Emerging markets business cycle models treat default risk as part of an exogenous interest rate on working capital, while sovereign default models treat income fluctuations as an exogenous endowment process with ad-noc default costs. We propose instead a general equilibrium model of both sovereign default and business cycles. In the model, some imported inputs require working capital financing; default on public and private obligations occurs simultaneously. The model explains several features of cyclical dynamics around default triggers an efficiency loss as these inputs are replaced by imperfect substitutes; and default on public and private obligations occurs simultaneously. The model explains several features of cyclical dynamics around deraults, countercyclical spreads, high debt ratios, and key business cycle moments.

Motivated by the recent European debt crisis, this paper investigates the scope for a bailout guarantee in a sovereign debt crisis. Defaults may arise from negative income shocks, government impatience or a "sunspot"-coordinated buyers strike. We introduce a bailout agency, and characterize the minimal actuarially fair intervention that guarantees the no-buyers-strike fundamental equilibrium, relying on the market for residual financing. The intervention makes it cheaper for governments to borrow, inducing them borrow more, leaving default probabilities possibly rather unchanged. The maximal backstop will be pulled precisely when fundamentals worsen.

This paper reviews empirical and theoretical work on the links between banks and their governments (the bank-sovereign nexus). How significant is this nexus? What do we know about it? To what extent is it a source of concern? What is the role of policy intervention? The paper concludes with a review of recent policy proposals.

The global economy has experienced four waves of rapid debt accumulation over the past 50 years. The first three debt waves ended with financial crises in many emerging market and developing economies. During the current wave, which started in 2010, the increase in debt in these economies has already been larger, faster, and broader-based than in the previous three waves. Current low interest rates mitigate some of the risks associated with high debt. However, emerging market and developing economies are also confronted by weak growth prospects, mounting vulnerabilities, and elevated global risks. A menu of policy options is available to reduce the likelihood that the current debt wave will end in crisis and, if crises do take place, will alleviate their impact.

An integrated approach to the economics of sovereign default Fiscal crises and sovereign default repeatedly threaten the stability and growth of economies around the world. Mark Aguiar and Manuel Amador provide a unified and tractable theoretical framework that elucidates the key economics behind sovereign debt markets, shedding light on the frictions and inefficiencies that prevent the smooth functioning of these markets, and proposing sensible approaches to sovereign debt management. The Economics of Sovereign Debt and Default looks at the core friction unique to sovereign debt—the lack of strong legal enforcement—and goes on to examine additional frictions such as deadweight costs of default, vulnerability to runs, the incentive to “dilute” existing creditors, and sovereign debt’s distortion of investment and growth. The book uses the tractable framework to isolate how each additional friction affects the equilibrium outcome, and illustrates its counterpart using state-of-the-art computational modeling. The novel approach presented here contrasts the outcome of a constrained efficient allocation—one chosen to maximize the joint surplus of creditors and government—with the competitive equilibrium outcome. This allows for a clear analysis of the extent to which equilibrium prices efficiently guide the government’s debt and default decisions, and of what drives divergences with the efficient outcome. Providing an integrated approach to sovereign debt and default, this incisive and authoritative book is an ideal resource for researchers and graduate students interested in this important topic.

This paper studies the effect of sovereign debt restructurings with external private creditors on growth during the period 1970-2010. We find that there are bad and good (or not so bad) debt restructurings for growth. While growth generally declines in the aftermath of a sovereign debt restructuring, agreements that allow countries to exit a default spell (final restructurings) are associated with improving growth. The impact can be significant. In general, three years after restructuring, growth is about 5 percent lower compared to countries that did not face restructuring over the same period. The exception is for final restructurings, which result in positive growth in the years immediately after the restructuring. Final restructurings tend to be better for growth because they reduce countries’ debt, with the strongest effect for countries that exit restructurings with relatively low debt levels.

A cutting-edge graduate-level textbook on the macroeconomics of international trade Combining theoretical models and data in ways unimaginable just a few years ago, open economy macroeconomics has experienced enormous growth over the past several decades. This rigorous and self-contained textbook brings graduate students, scholars, and policymakers to the research frontier and provides the tools and context necessary for new research and policy proposals. Martín Uribe and Stephanie Schmitt-Grohé factor in the discipline's latest developments, including major theoretical advances in incorporating financial and nominal frictions into microfounded dynamic models of the open economy, the availability of macro- and microdata for emerging and developed countries, and a revolution in the tools available to simulate and estimate dynamic stochastic models. The authors begin with a canonical general equilibrium model of an open economy and then build levels of complexity through the coverage of important topics such as international business-cycle analysis, financial frictions as drivers and transmitters of business cycles and global crises, sovereign default, pecuniary externalities, involuntary unemployment, optimal macroprudential policy, and the role of nominal rigidities in shaping optimal exchange-rate policy. Based on courses taught at several universities, Open Economy Macroeconomics is an essential resource for students, researchers, and practitioners. Detailed exploration of international business-cycle analysis Coverage of financial frictions as drivers and transmitters of business cycles and global crises Extensive investigation of nominal rigidities and their role in shaping optimal exchange-rate policy Other topics include fixed exchange-rate regimes, involuntary unemployment, optimal macroprudential policy, and sovereign default and debt sustainability Chapters include exercises and replication codes

In an environment characterized by weak contractual enforcement, sovereign lenders can enhance the likelihood of repayment by making their claims more difficult to restructure ex post. We show however, that competition for repayment among lenders may result in a sovereign debt that is excessively difficult to restructure in equilibrium. This inefficiency may be alleviated by a suitably designed bankruptcy regime that facilitates debt restructuring.

How creditors came to wield unprecedented power over heavily indebted countries—and the dangers this poses to democracy The European debt crisis has rekindled long-standing debates about the power of finance and the fraught relationship between capitalism and democracy in a globalized world. Why Not Default? unravels a striking puzzle at the heart of these debates—why, despite frequent crises and the immense costs of repayment, do so many heavily indebted countries continue to service their international debts? In this compelling and incisive book, Jerome Roos provides a sweeping investigation of the political economy of sovereign debt and international crisis management. He takes readers from the rise of public borrowing in the Italian city-states to the gunboat diplomacy of the imperialist era and the wave of sovereign defaults during the Great Depression. He vividly describes the debt crises of developing countries in the 1980s and 1990s and sheds new light on the recent turmoil inside the Eurozone—including the dramatic capitulation of Greece’s short-lived anti-austerity government to its European creditors in 2015. Drawing on in-depth case studies of contemporary debt crises in Mexico, Argentina, and Greece, Why Not Default? paints a disconcerting picture of the ascendancy of global finance. This important book shows how the profound transformation of the capitalist world economy over the past four decades has endowed private and official creditors with unprecedented structural power over heavily indebted borrowers, enabling them to impose painful austerity measures and enforce uninterrupted debt service during times of crisis—with devastating social consequences and far-reaching implications for democracy.

This paper studies the international propagation of sovereign debt default. We posit a two-country economy where capital constrained banks grant loans to firms and invest in bonds issued by the domestic and the foreign government. The model economy is calibrated to data from Europe, with the two countries representing the Periphery (Greece, Italy, Portugal and Spain) and the Core, respectively. Large contractionary shocks in the Periphery trigger sovereign default. We find sizable spillover effects of default from Periphery to the Core through a drop in the volume of credit extended by the banking sector.
