This paper proposes a semiparametric realized stochastic volatility model by integrating the parametric stochastic volatility model utilizing realized volatility information and the Bayesian nonparametric framework. The flexible framework offered by Bayesian nonparametric mixtures not only...

This paper suggests a new approach to evaluate realized covariance (RCOV) estimators via their predictive power on return density. By jointly modeling returns and RCOV measures under a Bayesian framework, the predictive density of returns and ex-post covariance measures are bridged. The forecast...

The recent Sino-U.S. trade conflict has made the impact of economic policy uncertainty (EPU) between China and the US on the global market gradually become a hot topic. This paper uses a spillover directional measure to investigate the cross-category spillovers among crude oil and gold markets...
