It is argued that in order to accommodate experimentally-observed choice patterns, it is not enough to model the utility function as being dependent on changes from a reference wealth point. Instead, individuals should be modeled as treating decisions as part of an identifiable sequence of...

Traditional accounts of "hindsight bias" inadequately distinguish "primary" hindsight bias from both "secondary" and "tertiary" hindsight bias. A subject exhibits primary bias when she assigns a higher ex ante probability estimate to actual outcomes, secondary bias when she believes that she...

This paper investigates the shape of the utility function for losses. From a rational point of view it can be argued that utility should be concave. Empirically, measurements of the utility for losses show mixed results but most evidence supports convex rather than concave utilities. However,...

Empirical studies of voting behavior provide evidence of bandwagon effects. Some voters, believing that a particular candidate will win, vote for this candidate even though they prefer the alternative. This paper provides a non-expected utility explanation of such behavior by positing that...
