Credibility And The Dynamics Of Stabilization Policy A Basic Framework

This paper studies price stabilization policy under both predetermined and flexible exchange rates. Under predetermined exchange rates, a non-credible stabilization program results in an initial expansion of output, followed by a later recession. The initial expansion accompanies an appreciating real exchange rate. Under flexible exchange rates, the recession occurs at the beginning of the program. The real exchange rate appreciates sharply on impact but depreciates afterwards. Lack of credibility is more costly under predetermined exchange rates because the real effects are more pronounced.

We study the effects of a credible, gradual exchange rate based disinflation program in a two sector economy. After an initial real exchange rate depreciation, the reductions in the rate of devaluation reduce the monetary wedge generated by a cash in advance constraint, leading to a gradual increase in absorption that yields progressive real exchange rate appreciations and current account deficits. An initial boom in economic activity is not followed by a later contraction, as labor supply expands during the whole length of the program.

This paper provides a critical survey of the literature on politico-institutional determinants of the government budget. We organize our discussion around two questions: Why did certain OECD countries, but not others, accumulate large public debts? Why did these fiscal imbalances appear in the last twenty years rather than sooner? We begin by discussing the “tax smoothing” model and conclude that this approach alone cannot provide complete answers to these questions. We then proceed to a discussion of political economy models, which we organize into six groups: (1) models based upon opportunistic policy makers and naive voters with “fiscal illusion”; (2) models of intergenerational redistributions; (3) models of debt as a strategic variable, linking the current government with the next one; (4) models of coalition governments; (5) models of geographically dispersed interests; and (6) models emphasizing the effects of budgetary institutions. We conclude by briefly discussing policy implications.

This paper analyzes stabilization policy under predetermined exchange rates in a cash-in-advance, staggered-prices model. Under full credibility, a reduction in the rate of devaluation results in an immediate and permanent reduction in the inflation rate, with no effect on output or consumption. In contrast, a non-credible stabilization results in an initial expansion of output, followed by a later recession. The inflation rate of home goods remains above the rate of devaluation throughout the program, thus resulting in a sustained real exchange rate appreciation.

This paper presents a broad overview of postwar analytical thinking on international macroeconomics, culminating in a more detailed discussion of recent progress. The paper reviews important empirical evidence that has inspired alternative modeling approaches, as well as theoretical and policy considerations behind developments in the field. The paper presents an empirical study of fiscal policy in countries with extreme monetary regimes. It also examines members of multilateral currency unions, dollarized countries that officially use the money of another country, and countries using currency boards.

The global financial crisis triggered severe shocks for developing countries, whose embrace of greater commercial and financial openness has increased their exposure to external shocks, both real and financial. This new edition of Development Macroeconomics has been fully revised to address the more open and less stable environment in which developing countries operate today. Describing the latest advances in this rapidly changing field, the book features expanded coverage of public debt and the management of capital inflows as well as new material on fiscal discipline, monetary policy regimes, currency, banking and sovereign debt crises, currency unions, and the choice of an exchange-rate regime. A new chapter on dynamic stochastic general equilibrium (DSGE) models with financial frictions has been added to reflect how the financial crisis has reshaped our thinking on the role of such frictions in generating and propagating real and financial shocks. The book also discusses the role of macroprudential regulation, both independently and through its interactions with monetary policy, in preserving financial and macroeconomic stability. Now in its fourth edition, Development Macroeconomics remains the definitive textbook on the macroeconomics of developing countries. The most authoritative book on the subject—now fully revised and expanded Features new material on fiscal discipline, monetary policy regimes, currency, banking and sovereign debt crises, and much more Comes with online supplements on informal financial markets, stabilization programs, the solution of DSGE models with financial frictions, and exchange rate crises

This book presents articles that focus on the inter-related issues of choice of exchange rate and monetary policy regimes, and others that use a global macroeconomic model developed by the author and collaborators to quantify the effects of the 'baby boom' on global imbalances, costs of disinflation, and the effects of German unification. The book presents new analysis of the euro-zone experience and its applicability to other monetary unions, as well as a discussion of the prerequisites for successful inflation targeting. It is grounded in real-world data, readily accessible to non-specialists, and addresses important economic policy issues.
