The Long-Run Relationship of Gold and Silver and the Influence of Bubbles and Financial Crises

This paper analyzes the long-run relationship between gold and silver prices. We closely follow Escribano and Granger (1998) and extend their study. We use a longer sample period from 1970-2011 and study the role of bubbles and financial crises for the relationship between gold and silver prices. We find clear evidence for a co-integration relationship between gold and silver with gold prices driving the relationship. The analysis also indicates that the results are influenced by bubble-like episodes and financial crises
