Abstract
Two non-transitive theories to model decision making under risk are regret theory (Loomes and Sugden, 1982, Loomes and Sugden, 1987) and salience theory (Bordalo et al., 2012). While the psychological underpinning of these two approaches is different, the models share the assumption that within-state comparisons of outcomes across choice options are a key determinant of choice behavior. We investigate the overlap between these theories and show that original regret theory (Loomes and Sugden, 1982) is a special case of salience theory (Bordalo et al., 2012), which itself is a special case of generalized regret theory (Loomes and Sugden, 1987).
