We develop an empirically highly accurate discrete-time daily stochastic volatility model that explicitly distinguishes … inter-dependencies among the shocks to returns and the two different volatility components. The model estimates suggest that … the leverage effect, or asymmetry between returns and volatility, works primarily through the continuous volatility …

The volatility premium is a well-documented phenomenon, which can be approximated by the difference between the … previous month level of the VIX Index and the rolling 30-day close-to-close volatility. In concordance with existing literature …, we show evidence that VIX is generally above the 30-day rolling volatility giving rise to the volatility premium, so that …

Stochastic volatility models are widely used in interest rate modeling to match the option smiles -- the two most …, Heston-LMM and SABR-LMM respectively.In this paper we consider the CEV model with a general stochastic volatility. Assuming … that rate-volatility correlation is zero we are able to obtain an exact integral representation of the option price …

In the current low-interest-rate environment, extending option models to negative rates has become an important issue. In our previous paper, we introduced the Free SABR model, which is a natural and an attractive extension to the classical SABR model. In spite of its advantages over the Shifted...

This paper attempts a re-examination of the relationship between the output volatility and economic growth using an … integrated (HFI) and low financially integrated (LFI) country groups. Overall, the results indicate that output volatility as a … proxy of macroeconomic volatility has negative effect on economic growth. The results appear to be stronger when we include …

The speed of convergence of the truncated realized covariance to the integrated covariation between the Brownian parts of two semimartingales is heavily influenced by the presence of infinite activity jumps with infinite variation. Namely, the two small jumps processes play a crucial role...
