What Determines the Shape of the Probability Weighting Function Under Uncertainty?
When valuing risky prospects, people typically overweight small probabilities and underweight medium and large probabilities, but there is vast heterogeneity in individual behavior. We explore the relationship between person-specific probability weights, estimated from investment decisions in a laboratory experiment, and personal characteristics. We find considerable interaction effects with ge...
متن کاملOn the shape of the probability weighting function.
Empirical studies have shown that decision makers do not usually treat probabilities linearly. Instead, people tend to overweight small probabilities and underweight large probabilities. One way to model such distortions in decision making under risk is through a probability weighting function. We present a nonparametric estimation procedure for assessing the probability weighting function and ...
متن کاملPsychophysics of the probability weighting function
A probability weighting function w(p) for an objective probability p in decision under risk plays a pivotal role in Kahneman-Tversky’s prospect theory. Although recent studies in econophysics and neuroeconomics widely utilized probability weighting functions, psychophysical foundations of the probability weighting functions have been unknown. Notably, a behavioral economist Prelec (1998) axioma...
متن کاملWhat determines the sticking probability of water molecules on ice?
We present both experimental and theoretical studies of the sticking of water molecules on ice. The sticking probability is unity over a wide range in energy (0.5 eV-1.5 eV) when the molecules are incident along the surface normal, but drops as the angle increases at high incident energy. This is explained in terms of the strong orientational dependence of the interaction of the molecule with t...
