Abstract
<p>Multivariate stochastic volatility (MSV) models and their extensions have been widely developed to capture multivariate volatility of returns of asset prices, such as stock prices and foreign exchange rates. As a return distribution of asset prices tends to be skewed, this paper introduces the MSV models with a skew-t distribution. A shrinkage method for skewness parameters is also introduced. An empirical analysis using daily stock returns in the S&P500 is provided to show that the skew-t distribution and the shrinkage method improve predictive ability of the MSV model.</p>
