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...

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 introduces the concept of range-dependent utility. Instead of reference dependence which evaluates outcomes relative to some reference point, we postulate dependence on a given lottery (set of lotteries) outcomes range. In this way the decision maker is a fully rational expected...

This short paper shows that the Allais Paradox and the Common Ratio Effect regarded as classic examples of the violation of the Expected Utility Theory Axioms – may be easily explained by assuming that changes in wealth (i.e. gains and losses) are perceived in relative terms. The preference...
