Preferences with Open Graphs: A New Result

Vohra, Ranjit - In: Economics Bulletin 34 (2014) 4, pp. 2267-2274

We provide a new characterization of binary relations that have an open graph. This result is applicable to any binary … relation on any topological space. The relationship of this new theorem to several known results for binary relations used for …

Revealed Preference and Nonparametric Analysis – Continuous Extensions and Recoverability

Heufer, Jan - 2012

This paper shows how revealed preference relations, observed under general budget sets, can be extended using closure operators which impose certain assumptions on preferences. Common extensions are based on the assumption that preferences are convex and/or monotonic, but we also consider...

Generalized KKM theorem, minimax inequalities and their applications

Tian, Guoqiang - Volkswirtschaftliche Fakultät, … - 1994

This paper extends the well-known KKM theorem and variational inequalities by relaxing the closedness of values of a correspondence and lower semicontinuity of a function. The approach adopted is based on Michael's continuous selection theorem. As applications, we provide theorems for the...

Transfer Method for Characterizing the Existence of Maximal Elements of Binary Relations on Compact or Noncompact Sets

Tian, Guoqiang; Zhou, Jianxin - Volkswirtschaftliche Fakultät, … - 1992

This paper systematically studies the existence of maximal elements for unordered binary relation on compact or noncompact sets in a general topological space. This is done by developing a method, called transfer method, to derive various necessary and sufficient conditions that characterize the...
