ambiguity model of decision making under uncertainty developed by Klibanoff, Marinacci and Mukerji (2005).  We revisit these … thought exeperiments and find, to the contrary, that they either point to strengths of the smooth ambiguity model compared to … experiment, raise criticisms that apply equally to a broad range of current ambiguity models. …

We propose and axiomatize a new model of preferences that achieves a separation between ambiguity, identified as a … characteristic of the decision maker's subjective information, and ambiguity attitude, a characteristic of the decision maker …

Are foundations of models of ambiguity-sensitive preferences too flawed to be usefully applied to economic models?  Al …-Najjar and Weinstein do not apply to quite a few of the ambiguity preference models of more recent vintage, and therefore to that … extent do not undermine the foundational aspects or applicability of ambiguity models in general.  Second, we argue the focus …

This paper axiomatizes an intertemporal version of the Smooth Ambiguity decision model developed in Klibanoff …, Marinacci, and Mukerji (2005). A key feature of the model is that it achieves a separation between ambiguity, identified as a … characteristic of the decision maker's subjective beliefs, and ambiguity attitude, a characteristic of the decision maker's tastes …

We report a portfolio-choice experiment that enables us to estimate parametric models of ambiguity aversion at the … of ambiguity aversion, one kinked and one smooth, that encompass many of the theoretical models in the literature. Each … specification includes two parameters: one for ambiguity attitudes and another for risk attitudes. We also estimate a three …
