In the literature on speculative attacks on a fixed exchange rate, it is usually assumed that the monetary authority responsible for fixing the exchange rate reacts passively to the monetary disruption caused by the attack. This assumption is grossly at odds with actual experience where...

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....

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...

The possibility that movements in market prices of assets or goods may be caused by self-fulfilling prophecies, called bubbles or sunspots, has long intrigued market observers. If bubbles or sunspots exist, market prices differ from their fundamental values, and markets do not necessarily...

This paper develops an open-economy model of the business cycle. Thenominal prices in the model are flexible and monetary nonneutrality isdeveloped using information confusion about the sources of disturbances todemand coupled with differential persistence of demand shocks. Firms useinventories...

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,...

In this paper we develop a rational expectations exchange rate model which is capable of confronting explicitly agents' beliefs about a future switch in exogenous driving processes. In our set-up the agents know with certainty both the initial exogenous process and the new process to be adopted...

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:...

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...

Fixed exchange rates are less volatile than floating rates. But the volatility of macroeconomic variables such as money and output does not change very much across exchange rate regimes. This suggests that exchange rate models based only on macroeconomic fundamentals are unlikely to be very...
