摘要
The aim of the paper is to analyse causality between the prices of four different metals: gold, silver, platinum and copper. The analysis conducted in this paper is a dynamic one, and the data used consist of monthly prices of futures contracts traded from the period January 2000 January 2012. The assessment of causality was carried out with the use of rolling regression applied to VAR models, which allowed for the assessment of the stability of relations between metal prices. The results obtained indicate that causality changed in the period analysed. Initially the price of copper was the Granger cause of the prices of the remaining metals, while in the later period the price of platinum became the Granger cause of the prices of the remaining metals. Past prices of gold and silver did not improve the forecasts of prices of other metals.
