This paper estimates a speculative attack model of currency crises in order to identify the role of economic fundamentals and any early warning signals of a potential currency crisis. The data from the Mexican economy was used to illustrate the model. Based on the results, a deterioration in fundamentals appears to have generated high one-step-ahead probabilities for the regime changes during the sample period 1982-1994. Particularly, increases in inflation differentials, appreciations of the real exchange rate, foreign reserve losses, expansionary monetary and fiscal policies, and increases in the share of short-term foreign currency debt appear to have contributed to the market pressures and regime changes in that period.

In the 1990s, currency crises in Europe, Mexico, and Asia have drawn worldwide attention to speculative attacks on government-controlled exchange rates and have prompted researchers to undertake new theoretical and empirical analysis of these events. This paper provides some perspective on this work and relates it to earlier research. It derives the optimal commitment to a fixed exchange rate and proposes a common framework for analyzing currency crises. This framework stresses the important role of speculators and recognizes that the government’s commitment to a fixed exchange rate is constrained by other policy goals. The final section finds that some crises may be particularly difficult to predict using currently popular methods.

Table of contents

This paper reviews recent developments in the theoretical and empirical analysis of balance-of-payments crises. A simple analytical model highlighting the process leading to such crises is first developed. The basic framework is then extended to deal with a variety of issues, such as: alternative post-collapse regimes, uncertainty, real sector effects, external borrowing and capital controls, imperfect asset substitutability, sticky prices, and endogenous policy switches. Empirical evidence on the collapse of exchange rate regimes is also examined, and the major implications of the analysis for macroeconomic policy discussed.

The management of financial crises in emerging markets is a vital and high-stakes challenge in an increasingly global economy. For this reason, it's also a highly contentious issue in today's public policy circles. In this book, leading economists-many of whom have also participated in policy debates on these issues-consider how best to reduce the frequency and cost of such crises. The contributions here explore the management process from the beginning of a crisis to the long-term effects of the techniques used to minimize it. The first three chapters focus on the earliest responses and the immediate defense of a currency under attack, exploring whether unnecessary damage to economies can be avoided by adopting the right response within the first few days of a financial crisis. Next, contributors examine the adjustment programs that follow, considering how to design these programs so that they shorten the recovery phase, encourage economic growth, and minimize the probability of future difficulties. Finally, the last four papers analyze the actual effects of adjustment programs, asking whether they accomplish what they are designed to do-and whether, as many critics assert, they impose disproportionate costs on the poorest members of society. Recent high-profile currency crises have proven not only how harmful they can be to neighboring economies and trading partners, but also how important policy responses can be in determining their duration and severity. Economists and policymakers will welcome the insightful evaluations in this important volume, and those of its companion, Sebastian Edwards and Jeffrey A. Frankel's Preventing Currency Crises in Emerging Markets.
