This paper proposes a four-regime bivariate Markov regime-switching model to estimate the daily time-varying minimum variance hedge ratios for West Texas Intermediate (WTI) crude oil, and evaluates its in- and out-of-sample hedging performances with two-regime model, CC-GARCH, TVC-GARCH, and OLS...

In this paper, we investigate the relationship between volatility of and liquidity provision through the aggregation of high-frequency data on the stock index option markets of Taiwan. Strong evidence shows the different behaviors of liquidity supply for market makers and nonmarket makers. In...

Using transactions and quotes data, we find significant magnet effects of price limit rules in Taiwan Stock Exchange (TSEC). Consistent with Subrahmanyam [Subrahmanyam, A., 1994. Circuit breakers and market volatility: a theoretical perspective. Journal of Finance 49, 237-254], we find that when...

This paper utilizes the most flexible skewed generalized t (SGT) distribution for describing petroleum and metal volatilities that are characterized by leptokurtosis and skewness in order to provide better approximations of the reality. The empirical results indicate that the forecasted...

This study provides a comprehensive analysis of the possible influences of jump dynamics, heavy-tails, and skewness with regard to VaR estimates through the assessment of both accuracy and efficiency. To this end, the ARJI model, and its degenerative GARCH model with normal, GED, and skewed...
