Investigating the relationship between gold and silver prices

Article Abstract:

Analysis of gold and silver price relationships reveals that non-linear models perform better than random walk in-sample and out of sample for gold prices, and that in-sample non-linear models are better for silver prices. The study evaluates the effects of large bubbles on price cointegration, the existence of simultaneous relationships between the rates of return of gold and silver and the extent of error-correction term inclusion improves non-linear models.
