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 …

We consider a tractable affine stochastic volatility model that generalizes the seminal Heston (1993) model by … variance, and we examine the impact of the distribution of jumps on the associated implied volatility smile. We provide … sufficient conditions for the asymptotic behavior of the implied volatility of variance for small and large strikes. In …

In a tractable stochastic volatility model, we identify the price of the smile as the price of the unspanned risks … traded in SPX option markets. The price of the smile reflects two persistent volatility and skewness risks, which imply a …-form and structural models of stochastic volatility …
