Although much of the theoretical literature on ambiguity works under the assumption of uncertainty aversion …-UA (for α-Uncertainty Attitude) preferences: a simple extension of the family of uncertainty averse preferences (Cerreia …-Vioglio et al., 2011b) with a Hurwicz-style mixing coefficient, so as to admit a richer range of uncertainty attitudes.

Examples include … multi-attribute decisions under uncertainty, such as some climate decisions, where trade-offs across attributes may be state … dependent. This paper proposes and characterises a model of uncertainty averse preferences that can simultaneously incorporate …
