DESCRIPTION:Building on the emerging literature on correlation preference r
 eflecting regret and salience considerations\, we offer an axiomatization o
 f correlation utility (CU) without requiring transitivity or completeness. 
 Under a correlation independence axiom\, CU specializes to correlation expe
 cted utility (CEU) which is not compatible with behavior in the correlated 
 Allais common-consequence problem. This motivates our correlation betweenne
 ss axiom and characterization of the corresponding correlation betweenness 
 utility (CBU). We investigate the implications of an absence of correlation
  sensitivity as well as (in)completeness for CEU and CBU. Under correlation
  insensitivity\, we demonstrate using the Kantorovich duality that CEU redu
 ces to EU while CBU reduces to a skew-symmetric bilinear utility together w
 ith weakening correlation independence to correlation projective independen
 ce\, reducing further to weighted utility under transitivity. Finally\, we 
 characterize correlation distribution reduction preference\, subsuming two 
 major generalizations of SEU: one maintains Savage’s Postulate 2 without 
 transitivity (Fishburn\, 1989)\; the other maintains transitivity without P
 ostulate 2 (Machina and Schmeidler\, 1992).\\n\\nContact: Gaëtan Fournier
