An extensive choice is a possibly indecisive choice behavior, in which all, some or none of the items in a menu may be selected. We describe a bounded rationality model for extensive choices, which relies on a pluralist paradigm. An extensive choice is s-pluralist if there is a population of...

Sufficientarianism is a prominent approach to distributive justice in political philosophy and in policy analyses. However, it is virtually absent from the formal normative economics literature. We analyze sufficientarianism axiomatically in the context of the allocation of 0–1 normalized...

Suflicientarianism is a prominent approach in political philosophy and in policy analyses. However, it is virtually absent from the formal normative economics liter­ature. We analyse suflicientarianism axiomatically in the context of the allocation of opportunities (formalised as chances of...

We describe a model that explains possibly indecisive choice behavior, that is, quasi-choices (choice correspondences that may be empty on some menus). The justification is here provided by a proportion of ballots, which are quasi-choices rationalizable by an arbitrary binary relation. We call a...

We study two related versions of the no-impatience postulate in the context of transitive and reflexive relations on infinite utility streams which are not necessarily complete. Both are excluded by the traditional (weak) anonymity axiom. We show explicit social welfare relations satisfying...
