RATIONAL CHOICE ON NONFINITE SETS BY MEANS OF EXPANSION-CONTRACTION AXIOMS
Sánchez, M.C.
Year of publication: 1995
Keywords: Rational Choice; Expansion Contraction Axioms; Nonf inite Sets.
Abstract
The rationalization of a choice function in terms of assumptions which involve expansion or contraction properties of the feasible set over nonfinite sets is analyzed. Schwartz's results [15], stated in the finite case, are extended to this more general framework. Moreover a characterization result when continuity conditions are imposed on the choice function as well as on the binary relation which rationalizes it is presented.
