“…In this study, the effects of VIX on commodity returns and their conditional volatilities will be examined and, in particular, it will determined if differential effects exist contingent on whether the VIX index is relatively high or low. Second, compared to the most commonly used Markov switching models where regimes are driven by unobservable Markov chains (see, e.g., Choi and Hammoudeh (2010) and Bhar and Malliaris, 2011)), threshold models utilize observable state variables, which permits one to relate certain asymmetric characteristics of the data with observable financial and economic factors. In this study, the threshold value for each commodity return is estimated after controlling for the market return (MSCI World Index), the VIX index, and the exchange rate.…”
