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 …

heteroskedastic processes with fat-tailed innovations in returns and volatility. We provide a tractable risk neutralization framework …

We consider a stochastic volatility model of the mean-reverting type to describe the evolution of a firm’s values … default probability. Our simulation results indicate that the stochastic volatility model tends to predict higher default … probabilities than the corresponding Merton model if a firm’s credit quality is not too low. Otherwise the stochastic volatility …

Stocks with high idiosyncratic volatility perform poorly relative to low idiosyncratic volatility stocks. We offer a … volatility (the positive contemporaneous relation between firm-level stock returns and idiosyncratic volatility). Our approach is … idiosyncratic volatility rises, driving down the firm's systematic risk and hence its expected return - firms with higher …
