This paper presents results of a study that has shed new light on the shape of indifference curves in the Marschak-Machina triangle. The most important observation concerns jumps in indifference curves at the triangle legs towards the triangle origin. Such jumps, however, do not appear at the...

This paper discusses solutions derived from lottery experiments using two alternative assumptions: that people perceive wealth changes as absolute amounts of money; and that people consider wealth changes as a proportion of some reference value dependant on the context of the problem under...

This paper presents the functional relationship between two areas of interest in contemporary behavioral economics: one concerning choices under conditions of risk, the other concerning choices in time. The paper first presents the general formula of the relationship between decision utility,...

Prospect Theory (1979) and its Cumulative version (1992) argue for probability weighting to explain lottery choices. Decision Utility Theory presents an alternative solution, which makes no use of this concept. The new theory distinguishes decision and perception utility, postulates a double...

This paper presents a nonparametric approach to classification of data from lottery experiments. Using very basic mathematical tools the paper endeavors to answer the questions: How to determine the "average" subject in a group? How to find a subject presenting the most similar behavior to a...

Prospect Theory (1979) and its Cumulative version (1992) argue for probability weighting to explain lottery choices. Decision Utility Theory presents an alternative solution, which makes no use of this concept. The new theory postulates a double S-shaped decision utility curve similar to the one...

This short paper demonstrates that the claim of Cumulative Prospect Theory (CPT) that people are risk seeking for loss prospects appears to be merely a result of using a specific form of the probability weighting function to estimate the power factor of the value function. Using experimental...

The paper presents a method for lottery valuation using the relative utility function. This function was presented by Kontek (2009) as 'the aspiration function' and resembles the utility curve proposed by Markowitz (1952A). The paper discusses lotteries with discrete and continuous outcome...

We introduce range and sign dependent utility, an integrative behavioral model for uncertain cash flows. For gambles played today, the model can be seen as an extension of original prospect theory based on range, rather than rank. For single future payouts, the model agrees with hyperbolic...
