Highly favorable external conditions have helped Latin America strengthen its economic fundamentals over the last decade. But, has the region built enough buffers to guard itself from a weakening of the external environment? This paper addresses this question by developing a simple framework...

Fiscal problems have long been considered a central feature of financial--that is, currency, debt, and banking--crises. This paper addresses four questions: What are the fiscal causes of crises? Which fiscal vulnerability indicators help to predict crises? Can fiscal variables explain the...

Although credit rating agencies have gradually moved away from a policy of never rating a private borrower above the sovereign (the "sovereign ceiling") it appears that sovereign ratings remain a significant determinant of the credit rating assigned to corporations. We examine this link using...

This paper proposes a new framework for the analysis of public sector debt sustainability. The framework uses concepts and methods from modern practice of contingent claims to develop a quantitative risk-based model of sovereign credit risk. The motivation in developing this framework is to...

This paper develops a comprehensive new framework to measure and analyze sovereign risk. Since traditional macroeconomic vulnerability indicators and accounting-based measures do not address risk in a comprehensive and forward-looking way, the contingent claims approach is used to construct a...

The paper examines the evolution of public sector debt levels and structures in 12 emerging market countries around the time of financial crises. In particular, it focuses on whether the debt situation of sovereign borrowers became more vulnerable in the aftermath of crises. The principal...

We develop an early-warning model of sovereign debt crises. A country is defined to be in a debt crisis if it is classified as being in default by Standard & Poor's, or if it has access to nonconcessional IMF financing in excess of 100 percent of quota. By means of logit and binary recursive...

Crises on external sovereign debt are typically defined as defaults. Such a definition accurately captures debt-servicing difficulties in the 1980s, a period of numerous defaults on bank loans. However, defining defaults as debt crises is problematic for the 1990s, when sovereign bond markets...

This paper introduces the Asset and Liability Management (ALM) compound option model. The model builds on the observation that the public sector net worth in a multi-period setting corresponds to the value of an option on an option on total government assets. Hence, the ALM compound option model...

This paper develops a new index which provides early warning signals of fiscal sustainability problems for advanced and emerging economies. Unlike previous studies, the index assesses the determinants of fiscal stress periods, covering public debt default as well as near-default events. The...
