Social welfare function
|Issue Date:||2003||Citation:||Sethuraman, J.,Piaw, T.C.,Vohra, R.V. (2003). Integer programming and arrovian social welfare functions. Mathematics of Operations Research 28 (2) : 309-326. ScholarBank@NUS Repository.||Abstract:||We characterize the class of Arrovian Social Welfare Functions (ASWFs) as integer solutions to a collection of linear inequalities. Many of the classical possibility, impossibility, and characterization results can be derived in a simple and unified way from this integer program. Among the new results we derive is a characterization of preference domains that admit a nondictatorial, neutral ASWF. We also give a polyhedral characterization of all ASWFs on single-peaked domains.||Source Title:||Mathematics of Operations Research||URI:||http://scholarbank.nus.edu.sg/handle/10635/44003||ISSN:||0364765X|
