An outcome below this reference outcome is regarded as resulting from a loss: a loss decreases the decision maker''s basic utility more than a comparable gain increases this utility. An elegant and simple method to model this phenomenon was proposed by Shalev (2002): the utility of an outcome below the reference outcome is obtained from the basic utility by subtracting a multiple of the loss in basic utility: this multiple, the loss aversion coefficient, is constant across different reference outcomes. We provide a preference foundation for this loss aversion model.
