报告简介：

We study a class of heterogeneous-agent endowment economies with long run risks in which the persistent component in the aggregate consumption growth process is unobservable. Agents holding different beliefs regarding the persistent component engage in Bayesian learning. Agents are averse to uncertainty arising from state estimation and have generalized recursive smooth ambiguity preferences. By examining a two-agent model with an elasticity of intertemporal substitution above 1 and reasonable risk aversion, we find that: 1) under recursive preferences without ambiguity aversion, the consumption share of the agent with the correct belief dominates in the long run, 2)smooth ambiguity, in conjunction with state uncertainty, generates uncertainty sharing motive that leads to long-run survival of both agents, and 3) the time-varying welfare weights of agents and their posterior beliefs well explain the time variation of price-dividend ratios in the data. We also examine long-run survival outcomes for alternative values of preference parameters as well as the case in which agents differ in their degrees of ambiguity aversion.
