An Improved Estimator For Black-Scholes-Merton Implied Volatility
Hallerbach, Winfried - Erasmus Research Institute of Management (ERIM), … - 2004
We derive an estimator for Black-Scholes-Merton implied volatility that, when compared to the familiar Corrado & Miller [JBaF, 1996] estimator, has substantially higher approximation accuracy and extends over a wider region of moneyness.

Level Shifts in Volatility and the Implied-Realized Volatility Relation
Christensen, Bent Jesper; Magistris, Paolo Santucci de - School of Economics and Management, University of Aarhus - 2010
We propose a simple model in which realized stock market return volatility and implied volatility backed out of option prices are subject to common level shifts corresponding to movements between bull and bear markets. The model is estimated using the Kalman filter in a generalization to the...

Summary statistics of option-implied probability density functions and their properties
Lynch, Damien; Panigirtzoglou, Nikolaos - Bank of England - 2008
The statistics that summarise probability density functions(pdfs) implied from option prices can be used to assess market expectations about future uncertainty, asymmetry and the probability of extreme movements in asset prices. A time-series analysis of these statistics for equity index and...

A comparison of implied and realized volatility in the Nordic power forward market
Birkelund, Ole Henrik; Haugom, Erik; Molnár, Peter; … - In: Energy Economics 48 (2015) C, pp. 288-294
In this paper we study implied and realized volatility for the Nordic power forward market. We create an implied volatility index with a fixed time to maturity. This index is compared to a realized volatility time series calculated from high-frequency data. The results show that the implied...
