We contrast two different asset pricing models, where the pricing kernel either (i) increases in the volatility … dimension, reflecting investors' aversion to volatility, or (ii) could be non-monotonic in volatility, reflecting heterogeneity … in investors' beliefs. The two models yield opposite predictions about volatility tail behavior, whereby the model with …

Financial markets exhibit high levels of volatility. Volatile markets are usually associated with high risks and … high volatility using a suitable hedging structure. One particular volatility hedge, involves taking a position in an …

This paper provides an empirical study on the predictability of implied volatility using dataset collected from the … implied volatility characteristics across various maturities. We applied both in and out-of-sample tests that include the … provides evidence of non-random movement in the implied volatility series and indicates predictability of implied volatility …

, and the corresponding implied volatility surfaces have been analyzed in some detail. In the non-asymptotic regimes, option … trivially expressed in terms of their implied volatility. Recently, attempts at calculating the asymptotic limits of the implied … volatility have yielded several expressions for the short-time, long-time, and wing asymptotics. In order to study the volatility …

We propose a model of volatility tail behavior, in which the pricing measure dominates the physical measure in both … tails of the volatility distribution and, hence, the derived pricing kernel exhibits an increasing and decreasing region in … the volatility dimension. The model features investors who have heterogeneity in beliefs about volatility outcomes, and …

between stock returns and idiosyncratic return volatility at the firm level. By allowing for the volatility of the underlying … idiosyncratic choice variables to exhibit independent switches between a high and low volatility regime, we show that the options …' constant expected returns are composed of (i) a state dependent drift term that relates positively with the volatility regime …

This paper estimates how the shape of the implied volatility smile and the size of the variance risk premium relate to … parameters of GARCH-type time-series models measuring how conditional volatility responds to return shocks. Markets in which … return shocks lead to large increases in conditional volatility tend to have larger variance risk premia than markets in …
