“…We examine the causal relationship between commodity prices and nominal exchange rates for three commodity currencies (Canada, Australia, Chile) and three commodity spot prices (crude oil, copper and gold), using daily data (and 5-minute data, for Canada). In view of the incomplete nature of causality at only one horizon, we study and compare causality at different horizons as proposed in Dufour and Renault (1998) and Dufour, Pelletier and Renault (2006). Further, to avoid the overly simplifying features of pure significance tests for non-causality, we compute measures at many horizons because they allow one to assess in a much more precise way the underlying linkages when causality at different horizons in different directions is present.…”
