Original and Cumulative Prospect Theory: A Discussion of Empirical Dierences
نویسندگان
چکیده
This paper discusses dierences between prospect theory and cumulative prospect theory. It shows that cumulative prospect theory is not merely a formal correction of some theoretical problems in prospect theory, but it also gives dierent predictions. Some experiments by Lola Lopes are re-analyzed, and are demonstrated to favor cumulative prospect theory over prospect theory. It turns out that the mathematical form of cumulative prospect theory is well suited for modeling the psychological phenomenon of diminishing sensitivity. *c 1997 by John Wiley & Sons, Ltd.

Composition Rules in Old and New Prospect Theory†
Original and cumulative prospect theory differ in the composition rule used to combine the probability weighting function and the value function. We test these composition rules by performing a novel test. We apply estimates of prospect theory’s weighting and value function obtained from two-outcome cash equivalents, a domain where original and cumulative prospect theory coincide, to three-outc...
متن کاملExplaining Heterogeneity in Risk Preferences Using a Finite Mixture Model
This paper studies the effect of the space (distance) between lotteries' outcomes on risk-taking behavior and the shape of estimated utility and probability weighting functions. Previously investigated experimental data shows a significant space effect in the gain domain. As compared to low spaced lotteries, high spaced lotteries are associated with higher risk aversion for high probabilities o...
متن کاملAn Axiomatization of Cumulative Prospect Theory for Decision Under Risk
Cumulative prospect theory was introduced by Tversky and Kahneman so as to combine the empirical realism of their original prospect theory with the theoretical advantages of Quiggin’s rank-dependent utility. Preference axiomatizations were provided in several papers. All those axiomatizations, however, only consider decision under uncertainty. No axiomatization has been provided as yet for deci...
متن کاملConditioning under Cumulative Prospect Theory
This paper derives conditions under which the standard decomposition of unconditional expected utility into marginal probabilities and conditional expected utilities generalizes to Cumulative Prospect Theory. The results are relevant for empirical analyses in which marginal probabilities are used as explanatory variables.
متن کاملTests of Cumulative Prospect Theory with graphical displays of probability
Recent research reported evidence that contradicts cumulative prospect theory and the priority heuristic. The same body of research also violates two editing principles of original prospect theory: cancellation (the principle that people delete any attribute that is the same in both alternatives before deciding between them) and combination (the principle that people combine branches leading to...
