volatility is associated with a rise in discount rates and a decline in consumption. To study the impact of volatility we provide … a framework in which cashflow, discount-rate, and volatility risks determine risk premia. We show that volatility plays … positive risk premium and help explain the cross-section of expected returns. Our evidence shows that volatility is important …

We show that a business-cycle component of consumption growth (dubbed business-cycle consumption) with cycles between 2 … and 4 years is effective in explaining the differences in risk premia across alternative test assets, including recently … aggregation of returns and consumption growth over suitable horizons. Consistent with our formalization, we show that the factor …
