I experimentally examine whether feedback about others' choices provides an anchor for decision-making under ambiguity … relative ambiguity attitude (compared to the peer's) significantly matters for shifts in individual attitudes, and that … dynamics considerably differ between gain and loss domains. For gains, learning to be comparably ambiguity averse increases the …

The existence of ambiguity presents a challenge to decision-makers as it eliminates the ability to apply standard …, ambiguity arises in most strategically important decisions in some form because of the genuine limits on the decision … problems as strategic decision-making under ambiguity where choices over resource investments must be made in competitive …

ambiguity aversion. This characterization extends to regret-based models as well. As an application of our general result, we … characterize dynamically consistent updating for two important models of ambiguity averse preferences: the ambiguity averse smooth … ambiguity preferences (Klibanoþ, Marinacci and Mukerji [Econometrica 73 2005, pp. 1849-1892]) and the variational preferences …

We propose a class of multiple-prior representations of preferences under ambiguity where the belief the decision … Optimism. The model does not restrict the sign of the DM's ambiguity attitude, and we show that it provides a unified framework … through which to characterize different degrees of ambiguity aversion, as well as to represent context-dependent negative and …

This paper analyzes dynamic choice for ambiguity-sensitive decision makers. It demonstrates that unambiguous behavioral … sophisticated MEU preferences are then used to analyze the value of information under ambiguity; a basic trade-off between …
