"fr" => "Nonlinear perception of risk is integrated into models of decision under ambiguity, thereby providing a theoretical basis for behavioral analyses that involve both risk and ambiguity. The main model replaces the risk front of maxmin expected utility by rank-dependent utility, and it is derived from simple, observable axioms that are not restricted to expected utility under risk. The model highlights the interaction between risk attitude and ambiguity attitude, and it is compatible with the paradoxical choices hypothesized by Machina. Following the same idea, nonlinear perception of risk can also be integrated into variational and multiplier preferences. When applied to comparative ambiguity attitudes, the idea enables more comparisons by allowing for both heterogeneous taste and perception of risk."

"fr" => "We adopt a definition of “rationality” as robustness to analysis: A mode of behavior is rational for a decision maker if she feels comfortable with it once it has been analyzed and explained to her. With this definition in mind, is it irrational to violate continuity axioms in one’s stated preferences? Specifically, does it make sense to avoid any positive probability of a negative outcome, no matter how small? Or, if a decision maker states such a “zero risk” policy, does she mean what she says? We propose to study this question axiomatically, asking which modes of behavior correspond to such statements. The baseline model evaluates a lottery by its expected utility and an extra additive term that measures the cost of deviating from a “zero risk” choice. A generalized version allows for multiple sets of principles, where the cost of risking a set of principles is added to the expected utility of a lottery. Stronger assumptions imply that the cost of violating a set of principles is additive in the individual costs. We develop a comparative behavioral analysis that allows making interpersonal comparisons about the relative importance of principles."

Consu-mers care about global warming, child labor, fair trade, etc. We develop an axiomaticmodel of intrinsic values—those that are carriers of meaning in and of themselves—andargue that they often introduce discontinuities near zero. For example, a vegetarian’s pre-ferences would be discontinuous near zero amount of animal meat. We distinguish intrin-sic values from instrumental ones, which are means rather than ends and serve as proxiesfor intrinsic values. We illustrate the relevance of our value-based model in different con-texts, including equity concerns and prosocial behavior."
