We test whether induced mood states have an effect on elicited risk and time preferences. Risk preferences between subjects in the control, positive mood, and negative mood treatments are neither economically nor statistically significant. However, we find that subjects induced into a positive...

We revisit the claims about the biological underpinnings of economic behavior by specifically exploring if observed gender differences in risk/time preferences can be explained by natural fluctuations in progesterone/estradiol levels during the menstrual cycle and by prenatal exposure to...

We elicit and compare risk preferences from student subjects and subjects drawn from the general population, using the multiple price list method devised by Holt and and Laury (2002). We find evidence suggesting that students have lower relative risk aversion than others.

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...
