A possibility of the existence of a discontinuity of Prelec’s (probability weighting) function W(p) at the probability p = 1 is discussed. This possibility is supported by the Aczél–Luce question whether Prelec’s weighting function W(p) is equal to 1 at p = 1, by the purely mathematical...

A need for experiments on the certainty effect near the certainty (near the probability p = 1) is stated in this paper. The need supported by the Aczél–Luce question whether Prelec’s weighting function W(p) is equal to 1 at p = 1, by the purely mathematical restrictions and the...

This paper investigates the behaviour in repeated decision situations. The experimental study shows that subjects show low or no risk-aversion, but put very high value on the opportunity to sell the lottery in every stage of the decision problem. There is evidence that risk attitudes depend on...
