We provide two ways to reconcile small values of the intertemporal elasticity of substitution (IES) that range between 0.35 and 0.5 with empirical evidence that the IES is large. We do this reconciliation using a model in which all agents have identical preferences and the same access to asset markets. We also conduct an encompassing test, which indicates that specifications of the model with small values of the IES are more plausible than specifications with a large IES.

JEL classification: E21, E32, O41

Key words: uncertainty, intertemporal elasticity of substitution, risk aversion, business cycles, growth
