The lattice structure of preference comparison

Gregorio Curello and Ludvig Sinander

Papers from arXiv.org

Abstract: Most comparisons of preferences have the structure of single-crossing dominance. We examine the lattice structure of single-crossing dominance, proving characterisation, existence and uniqueness results for minimum upper bounds of arbitrary sets of preferences. We apply these theorems to monotone comparative statics, ambiguity- and risk-aversion, social choice, and politically correct discourse.
