Best Complete Approximations of Preference Relations
Hiroki Nishimura, Efe A. Ok
We investigate the problem of approximating an incomplete preference relation on a finite set by a complete preference relation. We aim to obtain this approximation in s…
Monotonic Extensions of Lipschitz Maps
Efe A. Ok
We study the problem of extending an order-preserving real-valued Lipschitz map defined on a subset of a partially ordered metric space without increasing its Lipschitz constant an…
Measuring Stochastic Rationality
Efe A. Ok, Gerelt Tserenjigmid
Our goal is to develop a partial ordering method for comparing stochastic choice functions on the basis of their individual rationality. To this end, we assign to any stochastic ch…
A class of dissimilarity semimetrics for preference relations
Hiroki Nishimura, Efe A. Ok
We propose a class of semimetrics for preference relations any one of which is an alternative to the classical Kemeny-Snell-Bogart metric. (We take a fairly general viewpoint about…
Embedding of Topological Posets in Hyperspaces
Gerald Beer, Efe A. Ok
We study the problem of topologically order-embedding a given topological poset X in the space of all closed subsets of X which is topologized by the Fell topology and ordered by s…
Lipschitz Bernoulli utility functions
Efe A. Ok, Nik Weaver
We obtain variants of the classical von Neumann-Morgenstern expected utility theorem, with and without the completeness axiom, in which the derived Bernoulli utility functions are…
