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.

This paper reviews the literature on financial crises focusing on three specific aspects. First, what are the main factors explaining financial crises? Since many theories on the sources of financial crises highlight the importance of sharp fluctuations in asset and credit markets, the paper briefly reviews theoretical and empirical studies on developments in these markets around financial crises. Second, what are the major types of financial crises? The paper focuses on the main theoretical and empirical explanations of four types of financial crises—currency crises, sudden stops, debt crises, and banking crises—and presents a survey of the literature that attempts to identify these episodes. Third, what are the real and financial sector implications of crises? The paper briefly reviews the short- and medium-run implications of crises for the real economy and financial sector. It concludes with a summary of the main lessons from the literature and future research directions.

This paper examines credibility and reputational factors in explaining the December 1994 crisis of the Mexican peso. After reviewing events leading to the crisis, a model emphasizing the inflation-competitiveness trade-off is presented to explain the formation of devaluation expectations. Estimation results indicate that investors appear to have seriously underestimated the risk of devaluation, despite early warning signals. The collapse of confidence that followed the December 20 devaluation may have been the result of a shift in the perceived commitment of the authorities to exchange rate stability.

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.

''In summary, the book is valuable as a textbook both at the advanced undergraduate level and at the graduate level. It is also very useful for the economist who wants to be brought up-to-date on theoretical and empirical research on exchange rate behaviour.'' ""Journal of International Economics""
