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 …
