The lattice structure of preference comparison
Gregorio Curello and
Papers from arXiv.org
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.
