Assessing Debt Sustainability In Emerging Market Economies Using Stochastic Simulation Methods

This paper applies stochastic simulation methods to assess debt sustainability in emerging market economies and provide probability measures for projections of the external and public debt burden over the medium term. The vulnerability of public debt to adverse shocks is determined by a number of interrelated factors, including the volatility of output, financial fragility, the endogenous response of the risk premium, and sudden stops in private capital flows. The vulnerability of external debt is sensitive to the determination of the exchange rate and to the pricing of traded goods. We show that fiscal policy can act in a preemptive manner to prevent the debt burden from rising significantly over the medium term. This requires flexibility in fiscal planning, which many emerging market economies lack. Emerging market economies therefore face a difficult trade-off between managing the risk of a debt crisis and pursuing other important fiscal policy objectives.

This paper documents the specification of a model that was constructed to assess debt sustainability in emerging market economies. Key features of the model include external and fiscal sectors, which allow assessment of external and public debt in a unified framework; public and external debt, which both have an explicit maturity structure along with a distinction between denomination in domestic versus foreign currency to facilitate debt management analysis; monetary and fiscal policy, which are endogenous and specified using explicit forward-looking policy rules; an endogenous risk premium on public and external debt; and a mechanism for invoking a sudden stop in private capital flows. The paper provides an overview of the basic structure of the model, outlines the methodology used to calibrate the parameters, and illustrates the key properties of the model with reference to dynamic responses of selected variables to shocks of interest.

This paper critically reviews recent work regarding the sustainability of public debt. It argues that Debt Sustainability Analyses (DSAs) should be more than mere mechanical simulation exercises. Instead, a DSA should be linked to some objective regarding the distribution of fiscal burdens and distortions over time (in the tradition of Barro’s 1979 tax smoothing objective). The paper discusses objective functions that yield simple and transparent fiscal policy rules.

In this issue, a team of economists look at approaches to modeling the use of IMF resources in order to gauge whether the recent decline in credit outstanding is a temporary or permanent phenomenon. Era Dabla-Norris and Gabriela Inchauste examine what drives the growth of firms, with a focus on informality and regulations. Evan Tanner and Issouf Samake use a vector autoregression approach to examine the probabilistic sustainability of public debt in Brazil. Mexico, and Turkey. And Rachel Glennerster and Yongseok Shin ask whether transparency pays?that is, does the frequency and accuracy of macroeconomic information released to the public lead to lower borrowing costs in sovereign debt markets?

This edition of OECD's periodic survey of the Turkish economy presents an overview of recent economic performance and its outlook and examines how to enhance competitiveness and growth.

Alfred Maizels' work on commodity trade and prices documented trends in a major area of international economic relations. This book elaborates the ideas in the tradition of Maizels' contributons, and discusses and extends these theories in relation to current problems.

This paper examines the sustainability of fiscal policy under uncertainty in three emerging market countries, Brazil, Mexico, and Turkey. For each country, we estimate a vector autoregression (VAR) that includes fiscal and macroeconomic variables. Retrospectively, a historical decomposition shows by how much debt accumulation reflects unsustainable policy, adverse shocks, or both. Prospectively, Monte Carlo techniques reveal the primary surplus that is required to keep the debt/GDP ratio from rising in all but the worst 50 percent, 25 percent, and 10 percent of circumstances. Such a value-at-risk approach presents a clearer menu of policy options than currently used frameworks.
