We unify and expand the theory of consumer’s behavior, based on Samuelson’s Weak Axiomof Revealed Preference, to permit simultaneously both random choice and non-singletonchoice sets. We provide a consistency postulate for demand behavior when such behavior isrepresented in terms of a...

We model a general choice environment via probabilistic choice correspondences, with (possibly) incomplete domain and infinite universal set of alternatives. We offer a consistency restriction regarding choice when the feasible set contracts. This condition, 'contraction consistency', subsumes...

In dynamic resource allocation models, the non-existence of voting equilibria is a generic phenomenon due to the multi-dimensionality of the choice space even with agents heterogeneous only in their discount factors. Nevertheless, at each point of time there may exist a "median voter" whose...

In dieser Studie wird analysiert, ob die Kinderbetreuungszeit von Eltern in Deutschland über sozioökonomische und soziodemografische und haushalts-strukturelle Eigenschaften hinaus durch psychologische Persönlichkeitsmerkmale (Big Five) erklärt werden kann. Dabei werden innovative...

Behavioral implementation studies implementation when agents' choices need not be rational. All existing papers of this literature, however, fail to handle a large class of choice behaviors because they rely on a well-known condition called Unanimity. This condition says, roughly speaking, that...

This note provides an alternative proof of a known result on the existenceof collections of orderings generating intersection quasi-orderings. Instead of proving theresult from rst principles, it is illustrated how it can be obtained by making use of ananalogous relationship between partial...
