what Precious Metals act as safe havens and when some us evidence
Social Science Research Network, 2013Co-Authors: Brian M. LuceyAbstract:Gold’s role as a safe haven asset has been intensively studied in recent years. This paper extends the Precious Metals literature and examines the safe haven properties of four Precious Metals (gold, silver, platinum and palladium) against US stock and bond declines. We also examine how these results change over time. Results suggest that during some periods silver, platinum and palladium act as safe havens when gold does not. In some periods one or more of the other assets acts a stronger safe haven than does gold.

The macroeconomic determinants of volatility in Precious Metals markets
Resources Policy, 2010Co-Authors: Jonathan A. Batten, Cetin Ciner, Brian M. LuceyAbstract:This paper models the monthly price volatilities of four Precious Metals (gold, silver, platinum and palladium prices) and investigates the macroeconomic determinants (business cycle, monetary environment and financial market sentiment) of these volatilities. Gold volatility is shown to be explained by monetary variables, but this is not true for silver. Overall, there is limited evidence that the same macroeconomic factors jointly influence the volatility processes of the four Precious metal price series, although there is evidence of volatility feedback between the Precious Metals. These results are consistent with the view that Precious Metals are too distinct to be considered a single asset class, or represented by a single index. This finding is of importance for portfolio managers and investors.

The Macroeconomic Determinants of Volatility in Precious Metals Markets
Research Papers in Economics, 2008Co-Authors: Jonathan A. Batten, Cetin Ciner, Brian M. LuceyAbstract:We investigate key macroeconomic factors that impact the price returns of Precious Metals markets. The markets investigated were gold, silver, platinum and palladium; whereas the macroeconomic factors accommodated business cycle, monetary environment and financial market sentiment factors. The key findings present limited evidence that the same macroeconomic factors jointly influence the volatility processes of the Precious metal price series, although there is some evidence of volatility feedback between the Precious Metals. This finding lends weight to views that individual commodities are too distinct to be considered a single asset class or represented by a single index; a finding of considerable importance for portfolio managers and investors.

Dynamic relationship between Precious Metals
Resources Policy, 2013Co-Authors: Ahmet SensoyAbstract:Abstract We use a relatively new approach to endogenously detect the volatility shifts in the returns of four major Precious Metals (gold, silver, platinum and palladium) from 1999 to 2013. We reveal that the turbulent year of 2008 has no significant effect on volatility levels of gold and silver however causes an upward shift in the volatility levels of palladium and platinum. Using the consistent dynamic conditional correlations, we show that Precious Metals get strongly correlated with each other in the last decade which reduces the diversification benefits across them and indicates a convergence to a single asset class. We endogenously detect the shifts in these dynamic correlation levels and reveal uni-directional volatility shift contagions among Precious Metals. The results show that gold has a uni-directional volatility shift contagion effect on all other Precious Metals and silver has a similar effect on platinum and palladium. However, the latter two do not matter in terms of volatility shift contagion. Thus, investors that hedge with Precious Metals should, in particular, monitor the volatility levels of gold and silver.

Precious Metals recovery from waste printed circuit boards: A review for current status and perspective
Resources Conservation and Recycling, 2016Co-Authors: Yan Lu, Zhenming XuAbstract:Abstract Nowadays, rapid economic growth, continuous technological innovation and the improvement of living standards have result in large amounts of waste electric and electronic equipment (WEEE). Amongst all these WEEE, waste printed circuit boards (WPCBs) are considered as the most valuable components due to Precious Metals contained. Previous studies found that the presence of Precious Metals are richer in WPCBs than in typical metal mines, which are driven recycling Precious Metals from WPCBs to a profitable business without proper pollution controls in developing countries. However, recovering Precious Metals from WPCBs is a challenge because WPCBs are both valuable and harmful simultaneously, which are caused by their complex materials makeup. Hence, the proper technologies to recycle Metals from WPCBs without negative effects to the environment and human health are urgent and essential. In this article, the current Metals recycling technologies from WPCBs are reviewed. Then, an integrated technological route, including Metals enrichment and Precious Metals recovery, is proposed. Finally, in order to promote the development of Metals (Precious Metals) recovery from WPCBs, some improvements and recommendations in techniques and the future trend are also put forward.

Risk Management of Precious Metals
The Quarterly Review of Economics and Finance, 2011Co-Authors: Shawkat Hammoudeh, Farooq Malik, Michael McaleerAbstract:This paper examines volatility and correlation dynamics in price returns of gold, silver, platinum and palladium, and explores the corresponding risk management implications for market risk and hedging. Value-at-Risk (VaR) is used to analyze the downside market risk associated with investments in Precious Metals, and to design optimal risk management strategies. We compute the VaR for major Precious Metals using the calibrated RiskMetrics, different GARCH models, and the semi-parametric Filtered Historical Simulation approach. The best approach for estimating VaR based on conditional and unconditional statistical tests is documented. The economic importance of the results is highlighted by assessing the daily capital charges from the estimated VaRs.

Precious Metals exchange rate volatility transmissions and hedging strategies
International Review of Economics & Finance, 2010Co-Authors: Shawkat Hammoudeh, Michael Mcaleer, Yuan Yuan, Mark A ThompsonAbstract:This study examines the conditional volatility and correlation dependency and interdependency for the four major Precious Metals (i.e., gold, silver, platinum and palladium), while accounting for geopolitics within a multivariate system. The implications of the estimated results for portfolio designs and hedging strategies are also analyzed. The results for the four Metals system show significant short-run and long-run dependencies and interdependencies to news and past volatility. Furthermore, these results become more pervasive when the exchange rate and federal funds rate are included. Monetary policy also has a differential impact on the Precious Metals and the exchange rate volatilities. Finally, the applications of the results show the optimal weights in a two-asset portfolio and the hedging ratios for long positions.

The results for the four Metals system show significant short-run and long-run dependencies and interdependencies to news and past volatility. These results have become more pervasive when the exchange rate and FFR are included. Monetary policy also has a differential impact on the Precious Metals and the exchange rate volatilities. Finally, the applications of the results show the optimal weights in a two-asset portfolio and the hedging ratios for long positions.

recovery of high purity Precious Metals from printed circuit boards
Journal of Hazardous Materials, 2009Co-Authors: Young Jun Park, Derek J FrayAbstract:Abstract Waste printed circuit boards (WPCB) have an inherent value because of the Precious metal content. For an effective recycling of WPCB, it is essential to recover the Precious Metals. This paper reports a promising method to recover the Precious Metals. Aqua regia was used as a leachant and the ratio between Metals and leachant was fixed at 1/20 (g/ml). Silver is relatively stable so the amount of about 98 wt.% of the input was recovered without an additional treatment. Palladium formed a red precipitate during dissolution, which were consisted of Pd(NH 4 ) 2 Cl 6 . The amount precipitated was 93 wt.% of the input palladium. A liquid–liquid extraction with toluene was used to extract gold selectively. Also, dodecanethiol and sodium borohydride solution were added to make gold nanoparticles. Gold of about 97 wt.% of the input was recovered as nanoparticles which was identified with a high-resolution transmission electron microscopy through selected area electron diffraction and nearest-neighbor lattice spacing.
