When investment is repeated, previous outcomes (winning/losing) as well as the current budget level (gain/loss domain) influence decisions. The first is related to the so-called "gamblers fallacy". The second to value function relative to some reference point. Both effects have been extensively...

Despite the fact that conceptual models of individual decision making under risk are deterministic, attempts to econometrically estimate risk preferences require some assumption about the stochastic nature of choice. Unfortunately, the consequences of making different assumptions are, at...

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 experimental study investigates insurance decisions in low-probability, high-loss risk situations. Results indicate that subjects consider the probability of loss (loss size) when they make buying decisions (paying decisions). Most individuals are risk averse with no specific threshold...
