We analyze the time-dependence of exchange rate correlations using a new multivariate GARCH model. This model consists of two parts. First, we transform the exchange rate changes into their principal components and specify univariate GARCH models for all components. Second, we use the inverse of...

Empirical relationships between crude oil prices and exchange rates of oil exporting countries tend to vary over time. I use econometric models of the norwegian and canadian nominal exchange rates to investigate whether such time-variation could reflect shifts in the key oil price drivers over...
