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 suddenly jumps from one solution to another. This paper...

We present a model of a “soft” exchange rate target zone and interpret it as a stylized description of the post-August 1993 ERM. Our central bank targets a moving average of the current and past exchange rates, rather than the exchange rate’s current level, thus allowing the rate to move...

A typical strategy used by speculators to launch an attack on a fixed exchange regime is the use of forward markets. Central banks also intervene in forward markets to counter speculation. This paper addresses the question of how an attack is launched on the forward market, and what the optimal...

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...

A brief survey of the literature on speculative attacks is provided. The nature and causes of balance-of-payments crises, the implications for the behavior of the current account and the real exchange rate are discussed. Also, potential areas for future research on balance-of-payments crises are...

Bolivia has achieved noteworthy success over the past 15 years in raising incomes, reducing poverty, and maintaining macroeconomic stability by deploying commodity revenues to finance transfers, public investment, and state-led development, using an exchange rate peg as a policy anchor. However,...

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...

Money demand often surges after successful macroeconomic stabilization. This paper gives a name—financial infusion—to these surges because their size, unpredictability, and concurrence with other “success shocks” pose unique challenges to policy, especially under a money rule. An...

We specify an empirical framework to detect the effects of official intervention on real exchange rate dynamics. Using data for 27 advanced and emerging market economies, we find evidence that interventions are a near-universal practice; almost all countries intervene when real exchange rates...
