Liberty, equality, and impossibility: some general results in the space of ‘soft’ preferences

摘要

This paper is concerned with examining the mutual compatibility of the ethical principles of equity and liberty in a social choice framework of ordinally formulated vague preferences. With sufficiently weakened versions of the liberty and equity principles, one can secure an existence result in a ‘relation‐functional’ setting. However, difficulties tend to re‐appear in a ‘choice‐functional’ setting, when one subscribes to the notion that while preference may be vague, choice must perforce be exact.View full textDownload full textKeywordssoft binary preference relation, soft extended binary preference relation, modified equity, minimal liberalism, generalized soft aggregation rule, H‐rationalizability of a choice functionRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/17487870.2010.523970
