Does ambiguity matter? Estimating asset pricing models with a multiple-priors recursive utility Academic Article uri icon


  • 2014 Elsevier B.V. This paper considers asset pricing models with stochastic differential utility incorporating decision makers' concern with ambiguity on true probability measure. Under a representative agent setting, we empirically evaluate alternative preference specifications including a multiple-priors recursive utility. We find that relative risk aversion is estimated around 1-8 with ambiguity aversion and 7.4-15 without ambiguity aversion. Estimated ambiguity aversion is both economically and statistically significant and can explain up to 45% of the average equity premium. The elasticity of intertemporal substitution is higher than one, but its identification appears to be weak, as observed by previous authors.
