If currency crises are triggered when the currency overvaluation hits a threshold, the expected magnitude of a devaluation, conditional on its occurrence, is substantially different from the unconditional expected currency overvaluation. That is not true if currency crises are triggered by...

This paper investigates the theoretical properties of a class of 'second generation' models of currency crises as well as their applicability to empirical work. We show that under some conditions these models give rise to an arbitrarily large number of equilibria, as well as cyclic or chaotic...

This paper puts recent theoretical developments in the literature on currency crises in perspective by comparing two theoretical approaches, one based on the speculative attack model of Krugman-Flood-Garber and the other approach, which evolved following the 1992-93 crisis of the European...

The global financial crisis of 2007-09 has led to an intensive research program analyzing a wide range of issues related to financial crises. This paper presents a summary of a forthcoming book, Financial Crises: Causes, Consequences, and Policy Responses, that includes 19 contributions...

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...

The paper analyzes the integration of euro area sovereign bond markets during the European sovereign debt crisis. It tests for contagion (i.e., an intensification in the transmission of shocks across countries), fragmentation (a reduction in spillovers) and flight-to-quality patterns, exploiting...

In a country with high probability of default, higher interest rates may render the currency less attractive if sovereign default is costly. This paper develops that intuition in a simple model and estimates the effect of changes in interest rates on the exchange rate in Brazil using data from...

The paper considers three methods for eliminating the zero lower bound on nominal interest rates and thus for restoring symmetry to domain over which the central bank can vary its policy rate. They are: (1) abolishing currency (which would also be a useful crime-fighting measure); (2) paying...

In broad perspective, there have been essentially two competing views of the global financial crisis, albeit there are some complementarities among them. One view looks across the border: it mainly blames external imbalances, the large-scale mix of unprecedented pattern current account deficits...

This paper investigates empirically three potential drivers of financial imbalances ahead of the global financial crisis: rising global imbalances (capital flows); loose monetary policy; and inadequate supervision and regulation. We perform panel data regressions for OECD countries from 1999 to...
