Arrovian aggregation of MBA preferences : an impossibility result ; conference paper

Herzberg, Frederik

Cerreia-Vioglio, Ghirardato, Maccheroni, Marinacci and Siniscalchi (Economic Theory, 48:341-375, 2011) have recently axiomatised preferences in the presence of ambiguity as Monotonic Bernoullian Archimedean (MBA) preferences. We investigate the problem of Arrovian aggregation of MBA preferences - and prove dictatorial impossibility results for both finite and infinite populations.
