We develop a discrete-time real endowment economy featuring Epstein-Zin recursive utility and a Levy time-change subordinator, which represents a clock that connects business time to calendar time. This setup provides a convenient equilibrium framework for pricing non-Gaussian risks, where the solutions for financial prices are available up to integral operations in general, or in closed-form for tempered stable shocks. The non-Gaussianity of fundamentals due to time-deformation induces compensations for higher order moments and co-moments of consumption and dividend growth rates of the assets. Forecastability of the time change leads to predictability of the endowment streams and therefore to time-variation in financial prices and risk premia on assets. In numerical calibrations, we quantitatively analyze the compensations for different types of systematic risk.
