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 …

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 …

We develop a discrete-time affine stochastic volatility model with time-varying conditional skewness (SVS). Importantly …, we disentangle the dynamics of conditional volatility and conditional skewness in a coherent way. Our approach allows … autoregressive conditional heteroskedasticity (GARCH), and stochastic volatility with jumps (SVJ) models. Our results are not due to …

Volatility has been one of the most active and successful areas of research in time series econometrics and economic … empirical insights to emerge from this burgeoning literature, with a distinct focus on forecasting applications. Volatility is … inherently latent, and Section 1 begins with a brief intuitive account of various key volatility concepts. Section 2 then …

Current practice largely follows restrictive approaches to market risk measurement, such as historical simulation or RiskMetrics. In contrast, we propose flexible methods that exploit recent developments in financial econometrics and are likely to produce more accurate risk assessments, treating...

This paper proposes the new concept of stochastic leverage in stochastic volatility models.Stochastic leverage refers … stochastic volatility process. We provide a systematic treatment of stochastic leverage and propose to model the stochastic … tractable and allow for a direct economic interpretation. In particular, we propose two new stochastic volatility models which …
