The Retrospective Evaluation of Payment Sequences: Duration Neglect and Peak-and-End-Effects

Abstract

In this paper we present experimental research examining the ability of individuals to make good retrospective evaluations of payment sequences. Inspired by the evidence on systematic biases in the retrospective evaluation of affective episodes involving pain and pleasure we designed choice scenarios for payment sequences in which the existence of peak and end effects as well as duration neglect could be examined. There are two main results: We do not observe a systematic impact of payment sequence features (other than its sum) on the choices if subjects merely get delivered the payments without any affection or effort. Subjects, by and large, choose the sequence with the highest total payment. In a second scenario, in which payments were linked to the subjects? effort and performance in strenuous tasks, we observe a strong effect of duration neglect and a weaker, but still significant end effect. We further find that the mere number of peak losses in a sequence strongly influences its attractiveness. In this scenario subjects do not often choose the sequence with the highest total payment.
