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...

During the European exchange market turmoil in 1992-3 it was evident that speculative attacks tended to spread across currencies. Using a two-country version of the model developed by Flood and Garber (1984) we show how a speculative attack against one currency may accelerate the `warranted'...

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...

This paper provides a comprehensive evaluation of the short-horizon predictive ability of economic fundamentals and forward premia on monthly exchange rate returns in a framework that allows for volatility timing. We implement Bayesian methods for estimation and ranking of a set of empirical...

This paper proposes a theory of twin banking-currency crises in which both fundamentals and self-fulfilling beliefs play crucial roles. Fundamentals determine whether crises will occur. Self-fulfilling beliefs determine when they occur. The fundamental that causes ‘twin crises’ is government...

This paper argues that the recent Southeast Asian currency crises was caused by large prospective deficits associated with implicit bailout guarantees to failing banking systems. We articulate this view using a simple dynamic general equilibrium model whose key feature is that a speculative...

The impact of exchange rate fluctuations on international trade has long been a major concern for policy-makers. This is particularly the case in Europe, where countries trade extensively with each other. The crisis that began in the Summer of 1992 generated increased exchange rate fluctuations...

Existing models of exchange rate crises do not provide a good explanation for the breakdown of the ERM in 1992<196>3. This paper presents an alternative model which captures some of the important features of that period. The switch from a fixed to a floating rate is triggered by an optimizing...</196>
