In this paper, we examine the evolution of the S&P500 returns volatility around market crashes using a Markov …-Switching model. We find that volatility typically switches into the high volatility state well before a crash and remains in the high … volatility by uniformed traders result in a crash. …

We show that there is … substantial difference between the behavior of the East Asian return and volatility spillover indices over time. While the return … spillover index reveals increased integration among the East Asian equity markets, the volatility spillover index experiences …

In particular, we argue that putting in place institutional structures will not serve the purpose without addressing …

In recent years, numerous volatility-based derivative products have been engineered. This has led to interest in … constructing conditional predictive densities and confidence intervals for integrated volatility. In this paper, we propose … nonparametric estimators of the aforementioned quantities, based on model free volatility estimators. We establish consistency and …
