PREFERENCE STABILITY AND SUBSTITUTION OF INDIFFERENTS: A REJOINDER TO SEIDENFELD

摘要

Seidenfeld (Seidenfeld, T.[1988a], Decision theory without 'Inde- pendence' or without 'Ordering', Economics and Philosophy 4: 267-290) gave an argument for Independence based on a supposition that admissibility of a sequential option is preserved under substitution of indifferents at choice nodes (S). To avoid a natural complaint that (S) begs the question against a critic of Independence, he provided an independent proof of (S) in his (Seidenfeld, T. [1988b], Rejoinder [to Hammond and McClennen], Economics and Philosophy 4:309-315).
