The Wishart autoregressive (WAR) process is a powerful tool to model multivariate stochastic volatility (MSV) with correlation risk and derive closed-form solutions in various asset pricing models. However, making inferences of the WAR stochastic volatility (WAR-SV) model is challenging because...

This paper investigates how the presence of foreign investors in privatized firms affects privatization policy in a mixed oligopoly. We find that an increase in the stockholding ratio of foreign investors in a privatized firm increases the optimal degree of privatization, whereas an increase in...
