The present paper is intended to accomplish two tasks. First, models predicting overshooting and magnification, respectively, will be checked for their consistency with two key empirical regularities: A. The observed pattern of price level vs. exchange-rate volatility. B. The observed pattern of...

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...

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...

Regressions of ex post changes in floating exchange rates on appropriate interest differentials typically imply that the high- interest rate currency tends to appreciate, the `forward discount puzzle.' Using data from the European Monetary System, we find that a large part of the forward...

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...

In the context of a flexible-price monetary exchange rate model and the assumption of uncovered interest parity, we obtain a measure of the fundamental determinant of exchange rates. Daily data for the European Monetary System are used to explore the importance of non-linearities in the...
