This paper studies the intraday volatility of European government bonds under the framework of the multiplicative … component GARCH model (Engle and Sokalska, 2012). Intraday return volatility is specified as the product of daily volatility … debt crisis. We observe large transitory intraday volatility often due to illiquidity effects and outliers. We suggest a …

market volatility, but the risk premium for tail events cannot solely be explained by the level of the volatility. Our …

We provide empirical evidence of volatility forecasting in relation to asymmetries present in the dynamics of both … return and volatility processes. Using recently-developed methodologies to detect jumps from high frequency price data, we … variation. The leverage effect is separated into continuous and discontinuous effects, and past volatility is separated into …

frequency can be obtained almost as precisely as if volatility is observable by simply incorporating the strong information … content of realized volatility measures extracted from high-frequency data. For this purpose, we introduce asymptotically … exact volatility measurement equations in state space form and propose a Bayesian estimation approach. Our highly efficient …

We provide new empirical evidence on volatility forecasting in relation to asymmetries present in the dynamics of both … return and volatility processes. Leverage and volatility feedback effects of the S&P 500 price and volatility dynamics are … continuous volatility. Granted that jumps in both return and volatility are important components for generating the two effects …

Rogers-Satchell (RS) measure is an efficient volatility measure. This paper proposes quantile RS (QRS) measure to … on Standard and Poor 500 and Dow Jones Industrial Average indices show that volatility estimates using QRS measures …-of-sample forecast. For return models, the constant mean structure with Student-t errors and QRS volatility estimates provides the best …

Forecasting volatility models typically rely on either daily or high frequency (HF) data and the choice between these … two categories is not obvious. In particular, the latter allows to treat volatility as observable but they suffer from … these two family forecasting-volatility models, comparing their performance (in terms of Value at Risk, VaR) under the …
