I examine moment characteristics and predictability assumptions of dynamic asset pricing models. I propose a new measure --- the generalized entropy --- to summarize moment information of the multi-horizon pricing kernel for a dynamic model. Both static and dynamic strategy returns impose robust restrictions on the generalize entropy, providing a way to test candidate models. Applying this test to leading representative agent models and by creating dynamic strategies that depend on model-implied predictive signals, I find that models featuring growth uncertainty is able to explain market data better.
