Testing the hypothesis that international equity market correlation increases in volatile times is a difficult exercise and misleading results have often been reported in the past because of a spurious relationship between correlation and volatility. This paper focuses on extreme correlation,...

This paper relates the volatility of the (trade-weighted) effective real exchange rate to the degree of trade openness of an economy. The theoretical part presents an intertemporal monetary model with nominal labour (factor) market rigidities. Both monetary and aggregate supply shocks are shown...

The paper analyzes foreign investment and asset prices in a context of uncertainty over future government policy. The model endogenizes the process of learning by foreign investors facing a potentially opportunistic government, which chooses strategically the timing of a policy reversal in order...

We examine the effects of endogenously determined realignment expectations in a model of a target zone with sluggish price adjustment. We allow these expectations to be based on a policy rule which attaches differing weights to output and price stability. We find that for realistic parameter...

In credible target zone regimes, exchange rates should, according to Krugman's 1991 theory, spend a disproportionate amount of time near the edges of the fluctuation band. The major application of this theory has been to the European Monetary System (EMS), with several authors reporting that...

Many recent papers suggest that the basic flex-price target zone model does not perform well empirically. This paper derives some of the testable implications of a sticky-price target zone model in order to determine whether the assumption of perfect price flexibility explains the empirical...

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

The desire to avoid speculative runs on currencies appears to be one of the main reasons leading policy-makers to impose currency bands, but the standard analysis of target zones rules out any speculative inefficiencies by assumption. As an alternative we first present simple models of excess...

The paper argues that real world fixed exchange rate regimes usually have finite bands instead of completely fixed exchange rates between realignments because exchange rate bands, contrary to the textbook result, give central banks some monetary independence even with free international capital...

Using Krugman's (1991) target zone model, we find an explicit, sub-game perfect solution for a central bank wishing to stabilize the exchange rate given proportional costs of intervention. We demonstrate, however, that precommitment to narrower bands would yield a welfare gain - which provides a...
