In the 1990s, currency crises in Europe, Mexico and Southeast Asia have drawn worldwide attention to speculative attacks on government-controlled exchange rates. To improve our understanding of these events, researchers have undertaken new theoretical and empirical work. In this paper, we...

We develop a modified understand better the 1994 Mexican peso crisis as well as aspects of the European currency crises in 1992-93. We introduce the assumption that the speculative attack is sterilized by the domestic monetary authority, we incorporate a stochastic risk premium, and we allow for...

Most of the literature on two-tier exchange markets is built around models in which domestic policy can exert a powerful influence on the spread between the current account exchange rate and the capital account exchange rate. We show that if optimizing agents are risk neutral, domestic policy...

A developing country often pegs its exchange rate to a single currency, such as the U.S. dollar, even though it faces a higher inflation rate than the country to which it is pegged. As a consequence, it experiences real exchange-rate misalignments and a series of easily-anticipated devaluations....

The paper develops a general stochastic macroeconomic model which can be used to study the international transmission of disturbances under alternative exchange-rate systems. Four types of exchange-rate systems are considered: uniform flexible exchange rates, uniform fixed exchange rates,...

Though financial globalization should improve international risk sharing, empirical support is lacking. We develop a simple welfare-based measure that captures how far countries are from the ideal of perfect risk sharing. Applying it to data, we find some evidence that international risk sharing...

After the speculative attacks on government-controlled exchange rates in Europe and in Mexico, economists began to develop models of currency crises with multiple solutions. In these models, a currency crisis occurs when the economy jumps suddenly from one solution to another. This paper...
