The stochastic volatility model usually incorporates asymmetric effects by introducing the negative correlation between … the innovations in returns and volatility. In this paper, we propose a new asymmetric stochastic volatility model, based … between the innovations in returns and volatility. The new model is estimated by the efficient importance sampling method of …
